| Summary: | The oral drug delivery is the most generally used route of administration that has been explored for the
delivery of drugs through various pharmaceutical products. Solubility of drug plays critical role in achieving
the optimum therapeutic levels of the drug in blood and thus bioavailability. There are many drugs of
various therapeutic categories fall in Biopharmaceutics Classification System Classes II and IV as they lack
solubility. For all these drugs, dissolution is the big issue for the absorption process. Valsartan is an effective
antihypertensive agent and it can be used for the treatment of hypertension in most cases. The objective
of this study is to prepare Valsartan as an oral sachet which can be used as an alternative dosage form
after improvement of drug solubility using solubilizing agents such as sodium lauryl sulfate and tween 80.
Three different formulas of Valsartan sachet were prepared by conventional technique of wet granulation
method named conventional formula (Fc), sodium lauryl sulfate formula (Fs), and tween 80 formula (Ft) then
compared with the available marketed product of Valsartan tablet (Fd) as a reference. The preformulations
studies were conducted to exclude drug excipients interaction. Evaluation was performed in terms of
weight variation, dose content uniformity, and drug release study using dissolution test apparatus. Fourier
Transforms Infrared Spectroscopy reveals no drug excipient interaction and the drug release profile for Fs
and Ft formulas within 30 min was 100.16% and 104.16%, respectively, while for Fc only 57.55% of the
drug was released. This difference in the release profile was statistically significant (P < 0.05) between
Fs and Ft with Fc, but a non- significant difference (P > 0.05) was observed between Fs and Ft with
the marketed Valsartan tablet (Fd). The results support the possibility of using the prepared formulas Fs
and Ft as a Valsartan sachet for the oral administration alternative to conventional Valsartan tablets Fd |
