4. The oral mucosa represents a barrier to drug permeation and it is intermediate between skin epidermis and the gut in its permeability characteristics. The effectiveness of the buccal barrier and whether buccal absorption could provide means for Amiloride hydrochloride administration can be

determined by ex vivo permeation studies. Permeation studies were carried BTK inhibitors out on optimized formulation. Histological examination was performed to evaluate the pathological changes in cell morphology and tissue organization during administration of buccoadhesive tablets. The administration site of buccal tablet over the buccal mucosa did not cause any irritation, ulceration, inflammation and redness, and it resembles to controlled buccal mucosa. In vivo buccal diffusion studies were conducted for optimized formulations of both films and tablets in the rabbits showed zero order release pattern. The in vivo studies of buccal films of Amiloride hydrochloride

in rabbits did not show any inflammation or any other sensitization reactions at the administration site. In vitro and in vivo correlations were carried out for the therapeutic efficacy of pharmaceutical formulations and are governed check details by the factors related to both in vitro and in vivo characteristics of the drug. A graph was plotted by taking cumulative % in vitro release and cumulative % in vivo drug release for the same period of time and the release rate followed zero order, showing the correlation co efficient value to be 0.994. In vivo kinetic parameters were listed in Table 5, already and Fig. 5 are representing the in vivo data. Buccal films and tablets of Amiloride hydrochloride were prepared and evaluated in the present work. Films and tablets were prepared by solvent casting technique and compression method respectively, by employing

the various polymers alone and in combinations. All the physicochemical characteristics were evaluated, which showed satisfactory results with good buccoadhesive strength. The formulations were showing good stability in natural human saliva. Good correlation was observed between in-vitro and in-vivo profile, revealed the ability of the formulations to reproduce the in-vitro release pattern through the biological membrane. Hence Amiloride hydrochloride oral mucoadhesive buccal formulations which can be used mainly in minimizing dose and mainly help to improve the patient compliance and Amiloride hydrochloride is a drug of choice for delivery through the control release via buccal route. All authors have none to declare. The authors express sincere thanks to Management of Annamacharya college of Pharmacy and School of Pharmaceutical Sciences, JNTU-K, Kakinada for their cooperation in the present research work. “
“Among various approaches, preparation of drug embedded matrix tablets is one of the least complicated methods for obtaining controlled release and is widely applied in industry.
