New co-polymer zwitterionic matrices for sustained release of verapamil hydrochloride.
Stable co-polymer [vinyl acetate-co-3-dimethyl(methacryloyloxyethyl) ammonium propane sulfonate, p(VA-co-DMAPS)] latex of different compositions has been synthesized for the first time by emulsifier-free emulsion copolymerization. The unusual >>overshooting<< behavior of the co-polymer tablets has been explained by the formation of specific clusters from the opposite oriented dipoles-zwitterion...
متن کاملDesign and in Vitro Evalution of Sustained Release Film Coated Tablets of Verapamil Hydrochloride
An attempt was made to formulate the sustained release tablet of verapamil hydrochloride by using the wet granulation method for the treatment of hypertension. In the present formulation the tablets releases the loading dose by immediate drug release and maintenance dose up to 15 hours by extended release. The drug excipient compatability study was carried out with HPLC method and there was no ...
متن کاملSustained Release of Minocycline Hydrochloride from Biomaterials
Minocycline Hydrochloride (MH) is a second-generation, semisynthetic tetracycline antibiotic derivative (Figure 1). It blocks the association of aminoacyl-tRNA with the bacterial ribosome and thus inhibits the bacterial protein synthesis. Independent of its antibacterial property, MH also exhibits potent anti-inflammatory effects, which makes it a promising drug candidate to combat implant-asso...

متن کاملPreparation and In-Vitro Evaluation of Donepezil Hydrochloride Sustained Release Matrix Tablets Using Non-Gelling Polymer
The aim of the current investigation was to develop a Sustained release tablet of Donepezil Hydrochloride using nongelling polymer in order to overcome the problem of dose dumping. Viscarin GP-209 was used as a non-gelling release modifying agent. The formulated granule blends were evaluated for powder properties. Prepared tablets were subjected to post compression evaluations. In-vitro dissolu...
