Development and Validation of Stability Indicating RP-HPLC Method for Estimation of Rilpivirine Hydrochloride in Tablet Dosage Form

A simple, sensitive, rapid and reproducible HPLC Method was developed and validated for estimation of Rilpivirine in the presence of degradation products generated from forced decomposition studies. The analysis was carried out on Hypersil BDS C18, 250 X 4.6mm, 5? column using a mixture of ammonium acetate Buffer (pH to 6.0 0.05) and Acetonitrile in the proportion 55:45 respectively as a mobile phase at a flow rate of 1.2 mL/minute. The wavelength selected for the analysis was 300 nm. The peak for Rilpivirine HCl was observed at 10.33 minute. A linear response was observed in the range of 12.5 - 62.5 ?g/mL with a correlation coefficient of 0.999. The method was validated for specificity, linearity, precision, accuracy and robustness. The obtained results were indicating that the method is selective in analysis of Rilpivirine in the presence of degradation products formed under various stress conditions

DEVELOPMENT AND VALIDATION OF UV SPECTROPHOTOMETRIC METHOD FOR THE ESTIMATION OF ELVITEGRAVIR (EVG) IN BULK AND PHARMACEUTICAL FORMULATIONS

ABSTRACT A simple, rapid, precise and economical spectrophotometric method has been developed for quantitative analysis of Elvitegravir (EVG) in manufactured tablet formulation. The stock solution and subsequent dilution of Elvitegravir was done in methanol. The standard solution of Elvitegravir in methanol showed absorption maxima at 313.00 nm. The drug obeyed Beers-Lamberts Law in the concentration range of 1-100 μg/mL with coefficient of correlation (R 2 ) was 0.999 . The method can be adopted in routine analysis of Elvitegravir in bulk and tablet dosage form and it involves relatively low cost solvents and no complex extraction technique

RECENT RESEARCH ON ANALYTICAL METHODS OF ANALYSIS OF RALTEGRAVIR AND ELVITEGRAVIR : A REVIEW

ABSTRACT Highly Active antiretroviral therapy ( HAART ), a combination drug therapy is a topic of current interest in the treatment of HIV and AIDS. Techniques for the analysis and the quality control of antiretroviral drugs, particularly in the drug combinations are vital in achieving quality of these drugs and the treatments involved. Integrase inhibitor are a class of antiretroviral drug designed to block the action of integrase , a viral enzymes that inserts a viral genome into the DNA of the host cell. Since integration is a vital step in retroviral replication, blocking it can halt further spread of the virus. Integrase inhibitor were initially developed for the treatment of HIV infection . The HPLC,UV and HPTLC methods are available for the analysis of Raltegravir and Elvitegravir, the recently used drug for HIV and AIDS are reviewed in this articles
