摘要
The film‐forming potential of lanolin alcohol was evaluated. Inclusion of ethylcellulose in lanolin alcohol improved film integrity. The hardness and modulus of elasticity of these lanolin alcohol‐ethylcellulose films were improved by incorporating propylene glycol or cetyl alcohol. Triamcinolone acetonide release from selected film compositions was investigated. The data were analyzed from the viewpoint of the first‐order kinetic theory and the release from a planar system having a homogeneous or granular matrix. The results suggest that the drug release follows a diffusion‐controlled matrix model and a square root of time release profile. The release rate constants were proportional to drug concentration. Drug release was maximal from a system containing the drug in a near‐saturated solution. Copyright © 1979 Wiley‐Liss, Inc., A Wiley Company
