Study on Drug Delivery System of Poly(methyl- vinylsiloxane) and Levonorgestrel by Small Angle Laser Scattering

Department of Materials Science and Engineering, Tianjin University, Tianjin 300072

Received Date: 4 June 1997
Revised Date: 9 September 1997

Drug releasing process has been studied by small angle laser scattering. The le-vonorgestrel releasing process was followed with ultraviolet spectrometer. The effects of chain motions and the density fluctuations of the polymer on drug releasing process have been discussed.
