Abstract
A topical composition of a semi-solid consistency suitable is provided for transdermal application of prostaglandin E1. The composition comprises prostaglandin E1, a penetration enhancer, a polysaccharide gum, a lipophilic compound, and an acidic buffer system. The penetration enhancer :is an alkyl-2-(N,N-disubstituted amino)-alkanoate ester, an (N,N-disubstituted amino)- alkanol alkanoate, or a mixture of these. The lipophilic compound may be an aliphatic C1 to C8 alcohol, an aliphatic C8 to C30 ester, or a mixture of these. The composition includes a buffer system capable of providing a buffered pH value for said composition in the range of about 3 to about 7.4.
