| description | Delivery of losartan in a transdermal patch dosage form is challengging in
terms of formulation due to losartan�s low bioavailability and short elimination. This
study aimed to compare and to assess the effects of oleic acid and isopropyl alcohol
with concentration of 5% v/v and of 10% v/v in a transdermal patch formulation
using polyvinyl alcohol and polyvinylpyrrolidone as matrix. In addition, this study
also wanted to know the transport profile of losartan through rat skin membrane
experiment.
Patch formulas were determined by using the Simplex Lattice Design with
software Design Expert version 7.1.6. Physicochemical characteristic including the
visual impression, weight, thickness, loss on drying, the moisture uptake, and drug
content were determined. The best obtained formula was used to study transport of
losartan by using a vertical type diffusion cell and the data observed were analyzed
by using programme of WinSAAM version 3.0.3.
The results showed that patch the best formula obtained was a formula of
enhancer mixture 5% v/v are 4% v/v oleic acid and 1% v/v isopropyl alcohol, for
enhancer mixture 10% v/v are 2,68% v/v oleic acid and 7,31% v/v isopropyl alcohol.
The results of the physical test were not significantly different between observation
and theoretical values at the optimum conditions. Transport test showed that the
amount of drug was ready to be transported for enhancer mixture 5%v/v into the skin
was 15.51 µg, while the enhancer mixture 10%v/v was 28.17 µg. In adition, lag time
enhancer mixture 5% v/v start at 12 hours, while the lag time enhancer mixture of
10% v/v start at 13 hours since the transdermal delivery performed. |
