This investigation describes the preparation and in vitro evaluation of gastroretentive floating tablet of theophylline. Two hydrophilic cellulose derivatives, Methocel K100M and Methocel K15MCR were evaluated for their gel forming and release controlling properties. Sodium bicarbonate and citric acid were incorporated as gas generating agents. The effects(More)
In an Optical WDM network, link/path failure may occur in a very normal way which may cause a great amount of data loss if the link is not restored to reroute the affected traffic accurately and quickly using the redundancy the network. Wavelength Division Multiplexed (WDM) networks, employing wavelength routing have emerged as the dominant technology to(More)
Gastro retentive controlled release drug delivery system of Verapamil HCl was formulated to increase the gastric retention time of the dosage form with controlling the drug release pattern. Different grades of hydroxy propyl methyl cellulose derivatives; Methocel K4M and Methocel K15MCR were incorporated for their gel forming properties. Tablet buoyancy was(More)
Type 2 diabetes mellitus is a heterogeneous disease which involves both defective insulin secretion and peripheral insulin resistance. Despite the availability of other agents for treatment of type 2 diabetes mellitus gliclazide, is preferred in diabetic therapy because of its selective inhibitory activity towards pancreatic K +-ATP channels, antioxidant(More)
The present study was undertaken to formulate directly compressible tablets to investigate the effect of different disintegrating agents such as maize starch and avicel PH101 on disintegration time, in vitro drug dissolution and their release properties. Tablets of paracetamol and the combination of paracetamol and diclofenac using maize starch and avicel(More)
Bi-layer tablets of tramadol hydrochloride were prepared by direct compression technique. Each tablet contains an instant release layer with a sustained release layer. The instant release layer was found to release the initial dose immediately within minutes. The instant release layer was combined with sustained release matrix made of varying quantity of(More)
