Dave Год: 2013 Издание:LAP Lambert Academic Publishing Страниц: 84 ISBN: 9783659425288 A fixed dose combination of Ceftazidime(CEF) and Tazobactam(TAZO) is used as powder form of injection for the treatment of resistant lower respiratory tract and other infections. Stability indicating RP-HPLC and HPTLC methods were developed and validated for estimation of CEF and TAZO in an injection. RP-HPLC method was linear in the concentration range of 80-480 µg/mL and 10-60 µg/mL with R2 of 0.9998 and 0.9989 for CEF & TAZO respectively. Both the drugs were susceptible to acidic, alkaline and oxidative hydrolysis conditions. HPTLC method was linear in the concentration range of 1000-6000 ng/band for CEF and 2000-12000 ng/band for TAZO with R2 of 0.9993 and 0.9991 for respective drugs. The present work describes simple, economical and non interfering methods for estimation of CEF & TAZO. The methods were validated and found to be sensitive, accurate and precise. Percentage recovery shows that the method is free from interference of the excipients used in the formulation....
