Abstract

The aim of present study is to examine the in-vitro-in-vivo correlation (IVIVC) of immediate release product. Atenolol 100mg and its brands of immediate release dosage forms. Atenolol is clearly classified into BCS class III, and could be evaluated under bio waiver conditions. The in vitro parameters employed were hardness, weight uniformity, friability, disintegration time, absolute drug content, dissolution rate (in 0.1 N Hydrochloric acid, phosphate buffer and acetate buffer at 37ºC), and dissolution efficiencies were also analyzed. The in-vitro dissolution study was performed on the brands, according to FDA,USP  dissolution profile in three different PH (1.2),(4.5), and (6.8) at 37ºC, using the USP apparatus II,  then f1, f2 were determined for the time intervals of 10, 15, 30, 45 and 60 minutes, and dissolution efficiencies were calculated.  MINITAB 14 statistical program used for in vitro-in vivo correlation, level A was done for reference product. A non linear relation was established which is typical for immediate release formulation, of class III.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
