PREPARATION OF TRANSDERMAL DRUG DELIVERY SYSTEMS FOR TESTOSTERONE

ANDROGEN DEFICIENCY OCCURS WITH DISORDERS THAT DAMAGE THE TESTES, INCLUDING TRAUMATIC OR SURGICAL CASTRATION. THE AIM OF THIS PROJECT IS TO PREPARE TESTOSTERONE PATCHES OF DRUG-IN-ADHESIVE TYPE SUITABLE FOR MANUFACTURE IN THE LOCAL MARKET WITH CHEAP AVAILABLE COMPONENTS. THE USE OF EUDRAGIT E-100 MATRICES WITH THE INCORPORATION OF 5% W/W EUDRAGIT RL-100 SECONDARY POLYMER RESULTED IN INCREASING TESTOSTERONE RELEASE IN …
