aphthous stomatitis and oral lichen planus may be found on mucosal surfaces including the gingival, tongue and lips. these conditions frequently require topical corticosteroid medication such as triamcinolone acetonide (ta). recently, studies showed that divalent inorganic salts such as zinc sulphate (znso 4 ) are recommended for treatment of aphthouse, herpes ulcers and other ulcers in the bod...

Objective: Designing matrix structured controlled release systems using polymers or waxy lipids is a popular option today. Hollowbeads are formulations characterized by the formation of an air-filled cavity inside. In our study, indomethacin was chosen as model drug. Cetyl alcohol selected to create hollowbeads structure, and NaCMC achieve long-term release. Kollicoat® MAE100P used reduce and/o...

Objective: The objective of the present study was to formulate piperazine citrate tablets using natural aloe vera gum as a binding agent and evaluate tablets. Methods: extracted used for preparation tablets, characteristics are compared with an equivalent amount acacia sodium carboxymethyl cellulose (NaCMC) in different formulations Three batches were prepared (F1), NaCMC (F2), (F3) agents. ass...

The colon is a promising site for drug targeting owing to its long transit time and mild proteolytic activity. The aim of this study was to prepare new low methoxy amidated pectin/NaCMC microspheres cross-linked by a mixture of Zn(2+) and Al(3+) ions and test their potential for colonic targeting of progesterone. A 2(4) factorial design was carried out to optimize the preparation conditions. Hi...
