[0047] In all of the embodiments of the device shown hereinbelow, identical numbers refer to identical functions. All figures shown herein are illustrative and none is to scale.
[0048] The present invention teaches a device for delivering a predetermined amount of a substance, preferably comprising a medication or combination of medications, into a body orifice of a subject, the orifice comprising any of the body's natural orifices, including a nostril, the mouth, the ear, the throat, the urethra, the vagina, the rectum and any combination thereof.
[0049] In preferred embodiments of the device, the device comprises a delivery mechanism and a medicament capsule, as described hereinbelow. The device can apply a broad range of drugs and materials to the nasal cavity for local effect, deliver a broad range of drugs and materials through the nasal cavity to the systemic circulation, deliver a broad range of drugs and materials through the nasal cavity to the central nerve system (CNS) the brain, spinal cord and associated nerves, and any combination thereof.
[0050] The drugs to be applied could be, but are not limited to, pharmaceuticals, natural compounds, biologics, hormones, peptides, proteins, viruses, cells, stem cells and any combination thereof.
[0051] However, it should be emphasized that the device can be provided alone as well as in combination with a capsule.
[0052] In some cases, the capsule would be provided with a known medicament within the same and in other cases the capsule would be filled with the medicament just before use.
[0053] In some embodiments of the present invention, the device operating characteristics and the substance characteristics can be jointly optimized to maximize uptake of the substance at the desired site. In preferred variants of such embodiments, uptake is further optimized by exploiting synergies between delivery characteristics generated by the device and by the formulation or composition of the delivered material
[0054] In some embodiments, the substance comprises one or more agents to optimize delivery through the mucosal membrane by means of mucoadhesive agent and/or a permeability enhancer agent and/or a particulate formulation in the nano-particle or macro-particle range, and any combination thereof. In such embodiments, the combination of the device and substance enhance the delivery of the active agent to the target area (nasal epithelium and more specifically olfactory epithelium) and from there to the target tissue (for example the brain).
[0055] A non-limiting example is a composition comprising a drug to be delivered and at least one chemical permeation enhancer (CPE). In a preferred embodiment, the composition contains two or more CPEs which, by using a nasal delivery device, affect in an additive manner or behave synergistically to increase the permeability of the epithelium, while providing an acceptably low level of cytotoxicity to the cells. The concentration of the one or more CPEs is selected to provide the greatest amount of overall potential (OP). Additionally, the CPEs are selected based on the treatment. CPEs that behave primarily by transcellular transport are preferred for delivering drugs into epithelial cells. CPEs that behave primarily by paracellular transport are preferred for delivering drugs through epithelial cells. Also provided herein are mucoadhesive agents that enable the extension of the exposure period of the target tissue/mucus membrane to the active agent, for the enhancement of delivery of the active agent to and through the mucus membrane.
[0056] In contrast to prior-art nasal delivery devices and technologies, the devices of the present invention can produce a fine aerosol in the nasal cavity or other desired body orifice at the target area and at the location of the target tissue instead of producing the aerosol only within the device or immediately after exit from the device. Utilizing the pressure as a driving force and the air as a carrier allows the material to be released from the nozzle as a mixture of aerosol and a pre-aerosolized state. The properties of the resultant aerosol are typically dependent on the properties of the device and of the medium into which the device is discharged. The properties of the device which affect the aerosol characteristics are the delivery pressure, the volume of the delivery gas, the characteristics of its orifice and time to activate.
[0057] In some embodiments, the aerosol properties are fairly independent of the delivered substance, while, in other embodiments, the pressure, volume, orifice characteristics, and delivered substance properties can be co-optimized.
[0058] In prior-art devices the aerosol is produced in proximity exit of the device. Typically, the aerosol comprises a wide fan of aerosol and a low driving force. Therefore, large droplets typically deposit very close to the exit from the device, while smaller droplets tend to quickly contact the walls of the passage, so that deposition is typically predominantly close to the delivery end of the device, with little of the substance reaching desired sites deeper in the body orifice, such as the middle and superior turbinates of the nose.
