Buccal, polar and non-polar spray or capsule
View Patent ↗Buccal aerosol sprays or capsule using polar and non-polar solvent have now been developed which provide biologically active compounds for rapid absorption through the oral mucosa, resulting in fast onset of effect. The buccal polar compositions of the invention comprises formulation I: aqueous polar solvent 30-99.89%, active compound 0.001-60%, optionally containing flavoring agent 0.1-10%. Propellant 2-10%. The non polar composition of the invention comprises formulation II: non-polar solvent 20-85%, active compound 0.005-50%, and optionally flavoring agent 0.1-10% and propellant 50-80%.

spraying the oral mucosa of the mammal with a buccal spray composition, containing a pharmacologically active compound dissolved in a pharmacologically acceptable solvent, comprising in weigh percent of the composition:
an active compound in an amount of between 0.1 and 25 percent selected from the group consisting of a biologically active peptide, central nervous system active amine, sulfonyl urea, antibiotic, antifungal, sleep inducer, antiasthmatic, antiemetic, antiviral, histamine H-2 receptor antagonist, barbiturate, prostaglandin, or bronchial dilator;
a polar solvent in an amount between 10 and 97 percent; and
a propellant in an amount between 2 and 10 percent, wherein said propellant is a C 3 to C 5 hydrocarbon of linear or branched configuration.
2. The method of claim 1 , wherein the spray composition further comprises flavoring a agent in an amount between 0.05 and 10 percent by weight of the total composition.
3. The method of claim 2 , wherein the polar solvent is present in an amount between 20 and 97 percent by weight of the total composition, the active compound is presented in an amount between 0.1 and 15 percent by weight of the total composition, the propellant is presented in an amount between 2 and 10 percent by weight of the composition, and the flavoring agent is present in an amount between 0.1 and 5 percent by weight of the total composition.
4. The method of claim 3 , wherein the polar solvent is present in an amount between 25 and 97 percent by weight of the total composition, the active compound is present in an amount between 0.2 and 25 percent by weight of the total composition, the propellant is present in an amount between 2 and 10 percent by weight of the composition, and the flavoring agent is present in an amount between 0.1 and 2.5 percent by weight of the total composition.
5. The method of claim 1 , wherein the polar solvent comprises a polyethyleneglycol having a molecular weight between 400 and 1000 g/mol, C 2 to C 8 mono- and poly-alcohol or C 7 to C 18 alcohol of linear or branched configuration.
6. The method of claim 1 , wherein the polar solvent comprises aqueous polyethylene glycol.
7. The method of claim 1 , wherein the polar solvent comprises aqueous ethanol.
8. The method of claim 1 , wherein the active compound is selected from the group consisting of cyclosporine, clozapine, zidevudine, erythromycin, ondansetron, cimetidine, phenytoin, carboprost thromethamine, valerian, or a pharmaceutically acceptable salt thereof.
9. The method of claim 1 , wherein the flavoring agent comprises a synthetic or natural oil of peppermint, oil of spearmint, citrus oil, fruit flavor, sweetener or mixture thereof.
10. The method of claim 1 , wherein the polar solvent is present in an amount between 55 and 72 percent by weight of the total composition, the active compound is cyclosporine present in an amount between 15 and 25 percent by weight of the total composition, the propellant is present in an amount between 2 and 10 percent by weight of the composition, and the flavoring agent is present in an amount between 0.1 and 5 percent by weight of the total composition.
11. The method of claim 1 , wherein the polar solvent is present in an amount between 19 and 90 percent by weight of the total composition, the active compound is ondansetron hycrochloride present in an amount between 2.5 and 15 percent by weight of the total composition, the propellant is present in an amount between 2 and 10 percent by weight of the composition, and the flavoring agent is present in an amount between 1 and 10 percent by weight of the total composition.
12. The method of claim 1 , wherein the propellant comprises propane, N-butane, iso-butane, N-pentane, iso-pentane, neo-pentane, or a mixture thereof.
13. A method for administering an effective amount of a pharmacologically active compound to a mammal to provide transmucosal absorption of a pharmacologically effective amount of the active compound through the oral mucosa of the mammal to the systemic circulatory system of the mammal, comprising:
spraying the oral mucosa of the mammal with a buccal spray composition, containing a pharmacologically active compound dissolved in a pharmacologically acceptable solvent, comprising in weight percent of the composition:
an active compound in an amount between 0.1 and 25 percent selected from the group consisting of an antihistamine, alkaloid, hormone, benzodiazepine or analgesic;
a polar solvent in an amount between 10 and 97 percent; and
a propellant in an amount between 2 and 10 percent, wherein said propellant is a C 3 to C 8 hydrocarbon of linear or branched configuration.
