The objective of the present study was to develop clarithromycin tablets from polymeric hydrophilic matrices using methocel and characterization for its physic-chemical properties and in vitro release studies to optimize its release profile with the standard marketed product. Matrix tablets were prepared by wet granulation method using PVP and ethyl cellulose as binding agents. The matrix tablets were evaluated for its thickness, hardness, friability, weight variation, drug content and in vitro release studies. The drug delivery was analyzed using the paddle method in phosphate buffer pH 6.0 (dissolution medium I) and phosphate buffer pH 6.8 containing 0.5% sodium lauryl sulfate (dissolution medium II) and compared with USP dissolution limits. The dissolution release profile of formulation F9 was comparable with the market formulation and the difference factor and similarity factor f1 and f2 was found to be 2.44 and 83.18 in dissolution medium I; 1.44 and 89.71 in dissolution medium II. Stability studies were carried out as per ICH guidelines and tested for its physicochemical properties and in vitro studies. The study shows that the matrix method can be employed for preparing clarithromycin sustained release formulation using combination of hydrophilic polymers like Methocels and sodium carboxy methyl cellulose.
