ABSTRACT:
Transdermal dosage compositions are prepared from hydrated poly(vinyl alcohol) gels and pharmacologically active substances without any chemicals such as crosslinking agents and catalysts. Heating process is not involved in the gel preparation. High water contents of the gels enable the stratum corneum to be swollen, resulting in high permeation of drugs through the skin.
