ABSTRACT:
A mixture of nitroglycerin and a water-insoluble vinylpyrrolidone polymer provides a polymeric matrix which gradually releases nitroglycerin upon application to the skin of a patient in the form of a film, gel or ointment. The water-insoluble vinylpyrrolidone polymer may be an uncrosslinked copolymer or a crosslinked homopolymer or copolymer. The polymer provides increased stability and reduced volatility of the nitroglycerin while permitting slow and sustained release of the drug upon topical application to the skin.
