The aims of this study were to evaluate the dissolution performance of solid dosage forms using the open and closed modes of the FTC Apparatus 4 under different flow rates and provide examples to demonstrate the advantages of the FTC method, in particular the possibility of changing the pH during experiments, in studying the release mechanisms of extended-release products. Immediate-release (IR...
Dissolution methods are different for extended-release mesalamine capsules (pH 7.5 only) and delayed-release tablets (pH 1.4, 6.0, and 7.2). Mesalamine is used for the treatment of ulcerative colitis. The USP methods have several drawbacks in that they do not mimic gastrointestinal tract environments; tablets are removed from vessels to change dissolution medium; and neither method has been ado...
The present study was undertaken with an aim to formulate develop and evaluate Trimetazidine HCL extended release matrix tablets using different polymers as retarding agent. Pre formulation done initially results directed for the further course of formulation. Based on studies batches were prepared selected excipients. Powders evaluated tests Angle repose, Bulk density, tapped compressibility i...
mucoadhesive polymers that bind to the gastric mucin or epithelial cell surface are useful in drug delivery for the purpose of increasing the intimacy and duration of contact of drug with the absorbing membrane. several synthetic polymers are in use for this purpose. since the biodegradability of the synthetic polymers are questionable, in this investigation, an oral mucoadhesive controlled del...
