A simple, fast, accurate and precise reverse phase HPLC method is developed and described for the determination of ramelteon in tablet dosage form. Chromatography was carried on an ODS column using a mixture of acetonitrile and phosphate buffer pH 7.0 (35:65 V/V) as the mobile phase at a flow rate of 1.0 mL/min with detection at 286 nm. The retention time of the drug was 7.7 min. The procedure was validated for linearity, precision, accuracy, and robustness. The developed method was validated for linearity from 50 to 150% which shows the method is quite linear with a correlation coefficient of 0.999, for precision which includes system precision, method precision, intraday and by another analyst on another day, and accuracy. The %RSD for system precision was observed to be 1.1, whereas the method precision was observed to be 0.2. The % recovery from ‘accuracy’ studies yielded the recovery of 99.7-101.5% which indicates the capability of the method, and finally for robustness that includes studies w.r.t. change in flow rate, the percentage of organic modifier and pH. As per ICH guidelines, method validation results are in good agreement. The proposed method was simple, sensitive, precise and accurate.

The present research work illustrates the development and validation of RP HPLC method for simultaneous estimation of tenofovir disproxil fumarate, emtricitabine and rilpivirine hydrochloride in bulk and formulated in a pharmaceutical dosage form as a nanosupension. Antiretroviral drug treatment is the primary line of therapy for treating HIV. The multicomponent system formulated as a nanosuspension evidenced increased hydrophilicity, potency and decreased side effects. The separation was carried out by using efficient BDS hypersil C18 HPLC column with empower software. Combination method of Precipitation—ultrasonic homogenization was used for the preparation of the nanosuspension. The mobile phase used was methanol, water, acetonitrile (80:13.4:6.6) v/v and flow rate 1mL /min. The developed method was thus validated as per ICH guidelines for various parameters whose results advocated the reliability of the method. The results for parameters viz. retention times of tenofovir disproxil fumarate, emtricitabine and rilpivirine were 3.09 min, 2.78 min and 3.68 min, linearity range was between 7.5-90, 5-60, 0.625-7.5µg/mL, respectively.
