title: Statistical optimization of transdermal drug delivery system of terbutaline sulfate by factorial analysis.
abstract: A matrix type of transdermal drug delivery system of terbutaline sulfate was designed and developed by full 3(2) factorial method using polyvinyl alcohol (PVA) of medium molecular weight and polyvinyl pyrrolidone (PVP K-30) as matrix forming polymer and propylene glycol as plasticizer. Patches were designed to deliver 62 micrograms/cm2/hr of the drug into the systemic circulation. These were evaluated for in vitro skin permeation study through excised guinea pig skin. The permeation followed Higuchi kinetics, as its coefficients of correlation (r = 0.965-0.978) predominates over other permeation kinetics. Various physico-chemical parameters of the patches were investigated. Statistical optimization of in vitro permeation rate of the drug from the films were evaluated using two way analysis of variance (ANOVA), regression analysis.
