Formulation and Evaluation of Buccal Mucoadhesive Bilayered Tablets of Enalapril Maleate
Abstract: The buccal mucoadhesive bilayered tablets of Enalapril Maleate were fabricated with objective of avoiding first pass metabolism and prolonging the duration of action. The tablets were prepared by wet granulation wherein, one layer comprised of drug and bio adhesive polymer, whereas second layer consisted of drug free backing layer of ethyl cellulose. Bioadhesive polymers like Carbopol 934P and one either of three HPMC K4M/ HPMC K15M/ HPMC K100M were employed …

Formulation Development of Antihypertensive Buccal Patches and Characterisation
Abstract: Buccal patches containing atenolol and nifedipine were fabricated from mucoadhesive polymers like chitosan and hydroxypropyl methylcellulose (HPMC) 15CPS for the purpose of prolonging drug release and improving their bioavailability. The fabricated films were smooth, uniform and the colour was brown with good flexibility. The weight and thickness of all the formulations were found to be uniform. The drug content was in the range of 95–98%, indicating drug uniformity. Swelling index …

Gastro Retentive Drug Target System: Its Needs, Advantages, Limitation and Approaches
Abstract: Background: Gastro retentive drug delivery systems (GRDDS) address limitations of oral therapy for drugs with poor solubility, instability at intestinal pH, or narrow absorption windows by prolonging gastric residence and increasing contact with the gastric mucosa. Objectives: To review GRDDS approaches—floating systems, mucoadhesive systems, and super porous hydrogels—with emphasis on formulation strategies and polymer–excipient selection to enhance gastric retention, modulate buoyancy/swelling/adhesion, and ultimately improve oral bioavailability and therapeutic outcomes for …
