Losartan Potassium.

The Losartan Potassium buccal tablets have been developed as controlled drug delivery systems to improve the efficacy of Losartan Potassium through mucosal absorption, reduce dose frequency, toxicity, to improve bioavailability and patient compliance. Many processing variables can persuade the characteristics of the Losartan Potassium buccal tablets. The aim of the study was to study the effect of some selected process variables in the concentration of drug/locust bean gum, hydroxy propyl methyl cellulose K4M on the hardness, mucoadhesive strength and in-vitro release at different hours by applying central composite design, accounting the above independent variables. The central composite design with an R2 value of 0.9695, 0.9928, 0.5839, and 0.7556 has selected as a suitable model for further analysis. The model F value of 44.52, 277.61, 7.02, 15.46 with probability P>F
