Background

In 1.3 million U.S. emergency room visits per year, it is estimated that 170 million patients are involved in agitation, including patients whose agitation is a manifestation of schizophrenia or bipolar disorder.

The current standard of care for treating acute and exacerbating manic events in schizophrenia or bipolar I mania is by administering 5mg, 7.5mg or 10mg olanzapine (an atypical antipsychotic) by intramuscular Injection (IM). Although olanzapine IM is characterized by a rapid onset (reaching mean maximum plasma concentrations within 15 to 45 minutes), this route of administration is characterized by several injection-related acute side effects including injection site pain, excessive sedation, extrapyramidal syndrome and akathisia (Atkins et al, BMC Psychiatry 14,7 (2014); Battaglia et al, am.j.emerg.med.21: 192-charge 198 (2003); Kishi et al, j.psychiatr.res.68: 198-charge 209 (2015)). Moreover, the invasive intramuscular injection procedure may cause emotional trauma to the patient, whether collaborative or uncooperative, and may result in physical attack on hospital personnel attempting to inject. In addition, IM injections are contraindicated in cooperative patients (Nordstrom et al, west.j.emerg.med.13(1):3-10 (2012)).

Oral administration of olanzapine in standard tablets or orally disintegrating tablets has been approved for acute treatment of mania or mixed episodes associated with bipolar 1 disorder and does not suffer from many of the disadvantages of intramuscular injections in this patient population; however, there is a significant lag before effective blood levels are reached and agitation is reduced.

Pulmonary delivery of the typical antipsychotic drug loxapine by oral inhalation has been approved in 2017 for acute treatment of agitation associated with schizophrenia or bipolar 1 disorder in adults. However, the product label contains a black box warning: administration may cause bronchospasm, which may lead to respiratory distress and cessation (adasvre FDA product label, 8 months 2017), and the product is only available under risk assessment and mitigation strategies (REMS).

An effective non-invasive treatment of acute agitation can divert treatment from the emergency room to the "community" early in the onset of the agitation, with obvious benefits, including reduced emergency department visits and health economic burdens. Thus, there is a need for acute treatment of agitation, including agitation associated with schizophrenia and manic depression, which is rapid in onset and does not require parenteral injection.

Disclosure of Invention

We have developed a dry powder formulation of olanzapine suitable for intranasal delivery by a hand-held, manually actuated, propellant driven, metered dose intranasal applicator. After a single dose PK study in cynomolgus monkeys and rodents, we performed a phase I trial in healthy human subjects. In this phase I study, intranasal delivery of olanzapine formulations yielded similar or slightly higher plasma exposure (AUC) and maximum C compared to olanzapine administered IM at the same dose_max. In addition, median T after intranasal delivery of the formulation_max-three test doses in the range of 0.16-0.17 hours-significantly shorter than the median T measured for intramuscular and oral administration_maxShows that the olanzapine can be quickly and effectively absorbed across nasal epithelial cells。

Three standardized behavioral tests were used to measure pharmacodynamic effects. Behavioral testing has shown that intranasal administration of olanzapine produces similar or better sedation than IM or oral administration of olanzapine. Consistent with pharmacokinetic data, behavioral effects of olanzapine were observed significantly earlier in the group of subjects treated with intranasal olanzapine (INP105) than in the group of subjects treated with oral olanzapine (Zyprexa Zydis). These results indicate that intranasal delivery of olanzapine may be an effective method for acute treatment of agitation.

Summary of Experimental observations

We performed two single dose PK studies in cynomolgus monkeys to examine the pharmacokinetics following administration of a multi-powder olanzapine formulation delivered by the intranasal route using a non-human primate precision nasal delivery ("nhpPOD" or "NHP-POD") device. The formulations examined included unmodified crystalline powder, formulations containing HPMC and 1, 2-distearoyl-sn-glycero-3-phosphocholine (DSPC), and formulations containing HPMC and Pluronic F68. A placebo control also delivered intranasally by the nhpPOD device was microcrystalline cellulose.

PK results indicate that intranasal delivery of olanzapine formulations containing HPMC and DSPC using an nhpPOD device resulted in similar plasma exposure (AUC) and T as intramuscular administration of olanzapine_max. The formulated (HPMC/DSPC) powder produced 1.7 times higher AUC and 2.8 times shorter T compared to unformulated olanzapine (Cipla API)_max。

To further optimize Olanzapine (OLZ) formulation, approximately thirty different formulations were designed and manufactured for upper nasal delivery via the POD device. Formulations were tested, characterized and optimized for POD device compatibility. Stabilizers, penetration enhancers, particle size and manufacturing processes were also screened as part of the formulation development process.

In total twenty formulations were evaluated in a single dose PK study in rats (data not shown) and non-human primates (NHPs). The results show that administration of formulations F-OLZ #2, F-OLZ #5 and F OLZ #6 to NHPs via an NHP-POD device resulted in rapid absorption with a median T achieved in a short time_max(15, 15 and 23 minutes, respectively) and in less than 7 minutes more than 40ng/mL, which is approximately the plasma concentration achieved after 3X 10mg intramuscular injection in stable non-agitated patients (as reported in Zyprexa NDA 21253). Delivery of formulations F-OLZ #1, F OLZ #3 and F-OLZ #4 to NHPs via the NHP-POD device resulted in slower plasma absorption than the other 3 formulations, but still resulted in 30-60 min T_maxThis is compared to the time to reach peak plasma concentration (T) for oral Olanzapine (OLZ) tablets or orally disintegrating tablets_max5-8 hours) is significantly faster.

The pharmacodynamic effects of each nasal olanzapine formulation administered to NHPs were collected throughout each study. For T_maxThe shorter lead formulation, with visible sedation observed in NHP by 7 min blood draw, but not over-sedation, and this effect lasted 24 hours. This reported sedative effect was observed in all groups receiving nasal olanzapine, but with a delayed onset of action and less pronounced in the group with slower time to peak plasma concentrations and lower peak exposure.

The pharmacokinetic and pharmacodynamic effects of the intranasally administered formulation F-OLZ #2 (olanzapine formulation with HPMC and DSPC (INP105)) were further tested in a phase 1 clinical trial in healthy human subjects. In this study, intranasal delivery of olanzapine formulations yielded similar or slightly higher plasma exposure (AUC) and maximum C compared to olanzapine administered IM at the same dose_max. In addition, median T after intranasal delivery of the formulation_maxSignificantly shorter than the median T measured for olanzapine administered IM or orally_maxTo show thatOlanzapine is rapidly and efficiently absorbed across nasal epithelial cells.

Three standardized behavioral tests were used to measure pharmacodynamic effects — Visual Analog Scale (VAS); restlessness/calm rating scale (ACES); and digital sign replacement testing (DSST). These tests all show that intranasal olanzapine administration produces similar or better sedation than IM or oral administration of olanzapine. Furthermore, the behavioral effects of olanzapine were observed significantly earlier in the group of subjects treated with intranasal olanzapine (INP105) or IM olanzapine (Zyprexa IM) compared to the group of subjects treated with oral olanzapine (Zyprexa Zydis). This is consistent with pharmacokinetic results where it was found that intranasal delivery of olanzapine had a significantly shorter median T compared to IM or oral delivery_max. These results indicate that intranasal delivery of olanzapine may be an effective method for acute treatment of agitation.

Nasal drug delivery device

In various embodiments, the intranasal applicator device is a non-human primate precision nasal delivery ("nhpPOD") device described in fig. 7A-E, also described in U.S. patent No. 9,550,036, which is incorporated herein by reference in its entirety. In one embodiment, the intranasal device is one of the embodiments of fig. 1,2 and 9 of U.S. patent No. 9,550,036. In these embodiments, the pharmaceutical compound is loaded directly into the compound chamber.

An example nhpPOD apparatus is shown in figure 6.

Referring to fig. 6, a Metered Dose Inhaler (MDI) canister 602 dispensing 25 μ Ι of hydrofluoroalkane is attached to a plastic actuator 604.

Device 500 is also designed to simplify loading of the compound into device 500 by a clinician and use thereof. The device 500 may be reused to administer several doses of the compound.

Fig. 5B illustrates a partial cross-sectional view of a device 500 for intranasal delivery of a compound with a coupled tip, and separately illustrates a perspective view of the tip when disengaged. In the embodiment of fig. 5B, the device 500 includes an actuator body 502, a propellant canister 504, and a tip 506. The tip 506 includes an outer wall 508 and an inner wall 510, an outlet channel 512, an inlet interface 514, one or more grooves 528 (shown in fig. 5C), an outlet orifice 516, and a nozzle 518. Fig. 5B illustrates a compound container 520 coupled to the inlet interface 514. The compound contained in the compound container 520 may be a liquid or a powder. In the embodiment of fig. 5B, the compound is a powder.

As shown in fig. 5B, the device 500 includes a propellant canister 504 located within an actuator body 502. The propellant canister 504 contains a propellant. In one embodiment, the propellant may be pressurized. The propellant is a fluid, e.g., a liquid or a gas. In one aspect, the propellant is a liquid. In another aspect, the propellant is a gas. The propellant includes a pharmaceutically suitable propellant. Some examples of pharmaceutically suitable propellants include Hydrofluoroalkanes (HFAs), including but not limited to HFA, HFA 227, HFA134a, HFA-FP, HFA-BP, and similar HFAs. In one aspect, the propellant is a liquid HFA. In another aspect, the propellant is gaseous HFA. Additional examples of suitable propellants include nitrogen or chlorofluorocarbons (CFCs). Additionally, the propellant may be pressurized air (e.g., ambient air). The canister 504 may be a Metered Dose Inhaler (MDI) device that includes a pressurized canister and a metering valve 522 (including a valve stem) to meter propellant upon actuation. In one embodiment, a pump fitting (not shown) secures the metering valve 522 to the canister 504 and holds the two components in place during use of the device 500. A range of embodiments of the pump fitting include a fixed interface that retains the pump fitting within the actuator body 502, provides vertical displacement, and prevents rotation during installation of the canister 504.

The propellant canister 504 may have the ability to dispense propellant for a certain number of doses. In one embodiment, the device 500 may be shipped without the canister 504 and the canister 504 may be loaded into the actuator body 502 by a user. In some embodiments, the propellant canister may be replaced with a new propellant canister so that the device 500 may be reused. In one aspect, when the MDI device is actuated, a discrete amount of pressurized HFA fluid will be released. The MDI may contain between about 30 and about 300 actuations, inclusive, of the HFA propellant. The amount of fluid propellant released upon actuation may be between about 20 microliters (μ l) to about 200 μ l of liquid propellant, inclusive.

The actuator body 502 includes a propellant channel 524 that is in fluid communication with the propellant canister 504. The propellant channel 524 is in fluid communication with an inlet interface 514 configured to be coupled to the compound container 520 such that propellant released from the propellant canister 504 can be introduced into the compound container 520 via one or more grooves 528 on the inlet interface 514. In the embodiment of fig. 5B, the propellant channel 524 includes a port 526 at a distal end to receive the tip 506. In this configuration, the tip 506 may be coupled to and decoupled from the actuator body 502 by inserting the tip 506 into the port 526. In other embodiments, the port 526 may be inserted into the tip 506. In some embodiments, the port 526 and/or the tip 506 may include a sealed interface that creates a hermetic seal between the propellant channel 524 and the tip 506 such that propellant released from the canister 504 does not escape the propellant channel 524 but is directed toward the inlet interface 514.

The tip 506 may be coupled to the actuator body 502 and decoupled from the actuator body 502, which enables a user to load and unload the compound container 520 to and from the inlet interface 514. Tip 506 includes an outer wall 508 and an inner wall 510, wherein the inner wall forms an outlet passage 512 extending between the proximal and distal ends of tip 506. An inlet interface 514 is positioned around the distal end of the outer wall 508, the inlet interface 514 coupling a compound container 520. In the embodiment of fig. 5B, the inlet interface 514 is a collar that is insertable into the compound container 520. In other embodiments, the inlet interface 514 can be a ring, band, port, or band that interfaces with the compound container 520. The inlet interface 514 includes one or more grooves 528 (shown in fig. 5C) to direct propellant released from the canister 504 into the compound container 520 coupled to the inlet interface 514. The released propellant then contacts the compound within the compound container 520, agitating and entraining the compound and pushing the compound through the outlet channel 512 and out of the outlet orifice 516 located at the distal end of the outlet channel 512. In the embodiment of fig. 5B, the tip 506 includes a nozzle at the distal end of the outlet channel 512 to direct the released propellant and compound out of the outlet orifice in a narrow plume.

Fig. 5C is a perspective view of a tip 506 and a compound container according to one or more embodiments. In the embodiment of fig. 5C, the compound container 520 is a capsule. The capsule may be made of two parts that fit together. When separated, a portion of the capsule (e.g., a half-capsule, as shown in fig. 5E-5G) may be coupled to the tip 506. In use, the compound container 520 may contain a compound within a capsule. In one example, the compound is a powder. As shown in fig. 5E, the half-capsule includes an outlet opening 532 of the compound container 520. The outlet opening 532 may be coupled to the inlet interface 514 as shown in fig. 5F-5G. In the embodiment of fig. 5F-5G, the inlet interface 514 is inserted into the outlet opening 532, and the compound container 520 may be secured to the inlet interface 514 via an interference fit. In an alternative embodiment, the outlet opening 532 may be inserted into the inlet interface 514. As shown in fig. 5G-5H, the tip 506 has an outer wall 508 and an inner wall 510, with an outlet passage 512 formed by a bore or lumen through the inner wall 510. The outlet opening 532 fits around the inlet port 514 such that the compound container 520 and the outlet channel 512 are in fluid communication.

As shown in fig. 5F, 5G, and 5J, the inlet interface 514 is, for example, a ring, band, port, collar, or band that interfaces with the compound container 520. As shown in fig. 5C, 5E, 5F, 5K, 5L, 5M, 5N, 5O, and 5P, one or more grooves 528 are located on the inlet interface 514 and create a flow path for propellant released from the propellant canister 504 to travel into the compound container 520. Examples of grooves 528 include, but are not limited to, channels, slots, radial ports, or passages. The groove 528 provides a path through the inlet interface 514 through which propellant flows into the compound container 520. In one example, there are a plurality of grooves 528. The grooves 528 may be equally spaced around the inlet interface 514. The grooves 528 may be of equal size to one another or may be of different sizes. The grooves 528 extend along the length of the inlet interface 514 such that when the compound container 520 is coupled to the inlet interface 514, a first portion of each groove 528 is exposed within the propellant channel 524 and a second portion of each groove 528 is positioned within the compound container 520. As shown in fig. 5C, inlet interface 514 includes a ledge 530 that is designed to abut compound container 520 when coupled to inlet interface 514 and groove 528 extends beyond ledge 530 such that groove 528 is not completely covered by compound container 520.

In use, propellant released from the canister 504 flows through the propellant channels 524 and into the compound container 520 via the grooves 528, as shown by the direction of the arrows in fig. 5D. The outlet passage 512 is aligned with the outlet opening 532 of the compound container 520. Propellant flows into the compound container 520 in the groove 528 of the inlet interface 514 to agitate the powder, and powder and propellant exit the compound container 520 via the outlet opening 532 corresponding to the outlet channel 512. The propellant and powder mixture is carried through the outlet channel 512 through the nozzle 518 and exits the device 500 at the outlet orifice 516. In one example, the tip 506 may have one or more outlet orifices. The plume exiting the outlet aperture 516 has a narrow spray plume.

In one example of use of the device 500, at the time of use, the user divides the pre-filled capsule in half. In one example, the capsule is pre-filled with a powdered compound. The half-capsule is coupled to the tip 506 via an inlet interface 514. As shown in fig. 5P and 5Q, the tip 506 is then coupled to the actuator body 502. Propellant gas, for example from a refrigerant or compressed gas source, is directed through propellant channels 524 and toward the filled powder capsules. The groove 528 around the inlet interface 514 of the tip 506 introduces a high velocity jet of propellant gas that agitates the dry powder into a suspension within the propellant gas (data not shown, but confirmed by high speed close-up video). The grooves 528, which introduce gas tangentially to the hemispherical bottom of the compound container 520, create jets that will enhance powder agitation and entrainment. Once the powder is suspended, it is evacuated through the outlet opening 532 into the outlet channel 512 and out of the outlet orifice 516 of the device 500.

Generally, any shrinkage joint will cause powder blockage when accelerating the powder formulation through the restrictive orifice. Since the powder administered by the device 500 is suspended in the propellant gas prior to evacuation, it can be further throttled and directed without clogging the device. Thus, a much greater mass of powder can be delivered through a much smaller exit orifice without the device 500 being too long. The time from propellant actuation to the end of compound delivery is less than 1 second.

A groove 528 in the proximal end of the tip 506 will facilitate the flow of gas into the compound container 520. In one example, HFA gas is directed at the surface of the powder dose present in the compound container 520 (e.g., orthogonally or near orthogonally), which results in rapid agitation and entrainment of the powder. The hemispherical shape of the compound container 520 will facilitate redirection of the gas to the outlet channel 512 of the tip 506, as shown in fig. 5D. The arrows of fig. 5B and 5D illustrate the direction of propellant flow after the device 500 is actuated.

The actuator body 502 is attached and sealed to a propellant canister 504 and a tip 506, creating a pressurized flow path for the propellant gas. In certain aspects, the actuator body 502 is a reusable component. In certain aspects, the canister 504 is a reusable component.

In one example, compound container 520 is a standard size 3 drug capsule, but one skilled in the art would know how to use other sized drug capsules and modify device 500 to fit it. Additionally, in another example, the compound container 520 may not be a capsule, but another container capable of holding a compound, such as, but not limited to, an ampoule. In one example, the ampoule may be made of plastic, and in one example, it may be a blow-filled ampoule. To load the device 500, the user or clinician detaches the capsule containing the pre-filled formulation, discards the cap, and mounts the capsule over the tip 506. It is also possible for a clinician to fill an empty compound container 520 at the time of use and then mount the compound container 520 to the tip 506. In certain examples, the capsule is a disposable component.

The tip 506 receives the compound container 520 during loading and then couples to the actuator body 502 prior to use. When the propellant canister 504 is actuated, expanding propellant gas is introduced into the compound container 520 via the groove 528 around the inlet interface 514 of the tip 506. The resulting jet of propellant gas agitates and entrains the powder formulation within the compound container 520 which then exits through the outlet passage 512 and the outlet orifice 516 of the tip 506. In one example, the tip 506 is a disposable component. FIG. 5K illustrates an example measurement of the tip 506 in inches. In the embodiment of fig. 5N, the inlet interface 514 can include a radius along the bottom edge 222 to aid in placement of the compound container 520 onto the tip 506. The radius of curvature may range between about 0.005 inches and 0.025 inches, inclusive.

Fig. 5T and 5U illustrate perspective views of a second embodiment 534 of the tip. Similar to the tip 506, the tip 534 can be coupled to and decoupled from the actuator body 502, which enables a user to load and unload the compound container 536 from the tip 534 to use the device 500 for delivery to the user's upper nasal cavity. As shown in fig. 5T and 5U, the compound container 536 is a capsule. In one example, the compound container 536 can contain a powder. In the embodiment of fig. 5T and 5U, the tip 534 includes an inlet interface 538 for coupling with a compound container 536, wherein the inlet interface 538 has a piercing member 540. The piercing member 540 is designed to pierce the compound container 536 to create an opening in the compound container 536. The piercing member 540 may include a sharp point, a sharp corner, a knife-like edge, or other suitable geometry for piercing the compound container 536. In one embodiment, the inlet interface 538 comprises more than one piercing member 540, wherein each piercing member 540 is designed to pierce a compound container 536. The piercing members 540 may be positioned around the inlet interface 538 in a symmetrical or random pattern. In one embodiment, in use, a user can remove the spike 534 from the actuator body 502, load the compound container 536 into the port 526 of the propellant channel 524, and then insert the spike 534 back into the port 526. As the tip 534 is coupled to the actuator body 502, the piercing member 540 pierces the capsule. In this configuration, as shown in fig. 5U, the pierced capsule fits around piercing member 540. In an alternative embodiment, piercing member 542 can include a plurality of piercing points 544 that respectively pierce compound container 536. The plurality of puncture points 544 can be spaced around puncture member 542, or each

Fig. 5V and 5W illustrate perspective views of a piercing member 542 that can be used with the tip 534 according to one or more embodiments. As shown in fig. 5V, piercing member 542 can be a collar, ring, band, port, or band coupled to the pierced compound container 536. The piercing member 542 includes one or more piercing grooves 546, similar to the grooves 528, which form a flow path between the propellant channel 524 and the compound container 536. Propellant from the propellant canister 504 enters via one or more piercing grooves 546 of the piercing member 542, flows along the piercing grooves 546 and into the pierced compound container 536. As shown in fig. 5V and 5W, piercing member 542 includes a plurality of piercing openings 548. In the embodiment of fig. 5V, 5W, 5X, the puncture opening 548 is in fluid communication with the outlet channel 512. Propellant from the propellant canister 504 flows into the piercing recess 546, mixes with the powder in the pierced compound container 536, and flows into the piercing opening 544 to the outlet channel 512. The arrows in fig. 5X illustrate the flow path of the propellant. The outlet channels 512 provide a path for propellant and powder to the nozzle 518 and outlet orifice 516. The mixture of propellant and powder exits the device 500 via the outlet orifice 516. The plume exiting the device 500 is a narrow spray plume. In this embodiment, piercing member 542 may be integrally molded as a single piece or may be comprised of two or more pieces. In one example, the piercing member 542 may be a separate molded piece that acts in association with the inlet interface 538 (where the capsule is attached). In some embodiments, the inlet interface may include more than one piercing member 542.

As an alternative to a capsule being manually separated prior to placement on the tip 534, the tip 534 may include an integral piercing member 542 and piercing recess 546, as shown in fig. 5V and 5W. To create repeatable puncturing of the compound container 536, the piercing member 542 forms a single point, piercing point 544. In one example, puncture point 544 includes puncture openings 546 spaced radially about puncture point 544. The piercing opening 546 is in fluid communication with the outlet passage 512 to evacuate the powder from the compound container 536.

By allowing the propellant flow path to be created by the inline piercing motion, as shown in fig. 5X, loading of the compound container 536 onto the nib 534 is simplified for the user because the compound container 536 does not require manual manipulation and separation. In one example, piercing member 542 is integrally formed with tip 534. In one example, the filled compound container 536 can be filled and installed into the actuator body 502 or the tip 534 during manufacture of the device 500. In use, a user may apply linear motion to drive the piercing member 542 into the pre-filled compound container 536, thereby creating a complete gas flow path for metering prior to propellant actuation.

The present invention is further described in the following examples, which are not intended to limit the scope of the present invention.

Powder capsule

In one embodiment, a device was constructed and tested. The residual powder in the compound container after actuation was tested. When 2 or more but less than 6 grooves are used on the inlet interface, the device has comparable powder delivery performance as measured by the residue after actuation. In this example, the groove was combined with 63mg HFA propellant and the.040 "outlet orifice of the nozzle. Four grooves (every 90 degrees) were found to provide uniform gas delivery.

Dose mass

A dose mass reproducibility test was performed. The standard deviation of dose delivery indicates that the device is capable of delivering consistent dose quality. The average residual dose amount remaining in the device was < 5%, indicating that very little dose was lost in the device.

Intranasal devices with multiple cartridges

Fig. 7A illustrates another example of a non-human primate precision nasal delivery device 700, and fig. 7B illustrates a side view and a cross-sectional view of an actuator body 710 of the inter-nasal device 700 of fig. 7A. The device 700 may deliver the compound as a liquid, a powder, or some combination thereof. The device 700 includes a propellant canister 705, an actuator body 710, an extension tube 715 and a tip 720. Similar to the device 1, the propellant canister 705 is in fluid communication with the actuator body 710 such that propellant released from the propellant canister 705 travels through the actuator body 710, through the extension tube 715, through the nib 720, and out the outlet opening 725 of the nib 720. The compound may be loaded into the tip 720 such that as the propellant travels through the tip 720, the propellant contacts the compound and propels the compound to the outlet opening 725, where the propellant and compound exit in a plume.

Figure 7C illustrates a side view of the extension tube 715 of the inter-nasal device 700 of figure 7A. The extension tube 715 is a tube that includes an internal passage that creates fluid communication between the actuator body 710 and the tip 720. In the embodiment of fig. 7A-7D, a first end 730 of the extension tube 715 is coupled to the actuator body 710, while a second end 735 of the extension tube 715 is coupled to the tip 720, each of which is coupled via a respective connection interface 740a, 740b (collectively "740"). The connection hub 740 includes a luer lock with a male or female end on each side of the luer lock. In the embodiment of fig. 7A-7D, each connection interface 740 includes a luer lock having two male ends. Thus, the male ends of the connection interface 740a are inserted into the actuator body 710 and the first end 730, respectively, while the male ends of the connection interface 740b are inserted into the tip 720 and the second end 735, respectively. As illustrated in fig. 7C, the second end 735 may include a plurality of filter cartridges 745 positioned within the interior passage of the luer lock. The filter element 745 may be configured to convert the liquid propellant to a gas as the propellant passes through the filter element 745. Alternatively, the extension tube 715 in fig. 7B may be configured to convert the liquid propellant into a gas. The filter element 745 may be comprised of a porous material. The number of filter elements 745 may vary in different embodiments. As the number of filter elements increases, the intensity of the plume may decrease, for example, in terms of its impact force, velocity, plume width, other similar criteria, or some combination thereof. Similarly, the length of the extension tube 715 may be adjusted so that the propellant travels through a longer or shorter distance. Calibrating the intensity of the plume may enable the device 700 to accurately deliver the compound to the nasal cavity. Fig. 7D illustrates an enlarged view of the connection interface 740b at the second end 735 of the extension tube 715 of fig. 7C — the first example embodiment 750 includes a single filter element 745 and the second example embodiment 755 includes three filter elements 745 stacked in series. The number of filter elements 745 may be selected based on the type of compound. For example, a single cartridge 745 may be used for powder compounds while three cartridges 745 may be used for liquid compounds, or vice versa.

Figure 7E illustrates a side view and a cross-sectional view of the tip 720 of the inter-nasal device of figure 7A. The tip 720 is designed to be inserted into a nostril. The tip 720 includes an internal passage 760 and an outlet opening 725 for delivering the compound to the nasal cavity. In the embodiment of fig. 7E, the tip 720 includes a filter element 745 disposed within the interior passage 760. The filter element 745 may be configured to convert the liquid propellant to a gas as the propellant passes through the filter element 745. The filter element 745 may be comprised of a porous material. In the embodiment of fig. 7E, the tip 720 further includes a nozzle 765 at the distal end of the tip 720 proximate the outlet opening 725. The nozzles 765 can enhance deposition of the compound within the nasal cavity, such as to the upper olfactory region of the user. In some embodiments, the nozzle 765 can comprise a single orifice, while in alternative embodiments, the nozzle 765 can comprise multiple orifices (e.g., between 2 and 11 orifices). In some embodiments, the tip 720 may not include a nozzle. Different embodiments of the tip may be used based on the different types of compounds to be delivered to the nasal cavity of the user. For example, a tip for delivering a powder compound may not include a nozzle, while a tip for delivering a liquid compound may include a nozzle, or vice versa. In addition, the number of orifices in the nozzle may similarly vary based on the type of compound. A compound may be loaded into the tip 720 such that the compound is contained within the internal passage 760. In the embodiment of fig. 7E, compound is loaded into the tip 720 through the opening 770 at the proximal end of the tip 720 prior to disposing the filter element 745 within the internal passage 760. The cartridge 745 is then inserted to contain the compound inside the tip 720. In an alternative embodiment, such as one in which the tip 720 does not include a nozzle 765, the compound can be loaded into the tip through the outlet opening 725. In the configuration of fig. 7E, propellant travels from the propellant canister 705 through the actuator body 710 and extension tube 715, through the nib 720 and contacts the filter element 745, and then contacts the compound within the internal passage 760, pushing the compound through the outlet opening 725 where the propellant and compound exit in a plume that is delivered within the user's nasal cavity.

Experimental examples
