Buccal, polar and non-polar spray or capsule

Abstract

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%.

[0001] This application is a continuation in part of applicant PCT application PCT / US97 / 17899 filed Oct. 1, 1997.BACKGROUND OF THE INVENTION

[0002] It is known that certain biologically active compounds are better absorbed through the oral mucosa than through other routes of administration, such as through the stomach or intestine. However, formulations suitable for such administration by these latter routes present their own problems. For example, the biologically active compound must be compatible with the other components of the composition such as propellants, solvents, etc. Many such formulations have been proposed. For example, U.S. Pat. No. 4,689,233, Dvorsky et al., describes a soft gelatin capsule for the administration of the anti-coronary drug nifedipine dissolved in a mixture of polyether alcohols. U.S. Pat. No. 4,755,389, Jones et al., describes a hard gelatin chewable capsule containing nifedipine. A chewable gelatin capsule containing a solution o...
