Abstract:
Daclatasvir dihydrochloride is an antiviral drug used in the treatment of Hepatitis C and for its estimation in drug product, no Pharmacopeial method is available. Therefore, a simple, rapid, precise and accurate isocratic RP-HPLC method was developed and validated for quantification of daclatasvir dihydrochloride in pharmaceutical dosage form. The quantification was carried out using Hypersil ODS - C18 Column (250mm, 4.6mm, 5μm), Shimadzu LC-2030 Prominence-I Series. The mobile phase composed of phosphate buffer (pH 3.5, adjusted with ortho phosphoric acid) and acetonitrile (60:40 v/v). The flow rate was 1.0ml/min with UV detection at 308 nm. The validation of developed method was conducted for specificity, linearity, accuracy, precision, LOD and LOQ. A linearity was established in the concentration range of 0.5-150% with coefficient of correlation 0.9993. The limit of detection (LOD) was 0.005μg/ml and the limit of quantification (LOQ) was 0.01μg/ml. The method was successfully applied to the assay and in-vitro dissolution studies of daclatasvir dihydrochloride in tablet dosage form. It can be concluded that this method can be very helpful in the quality control estimation of daclatasvir dihydrochloride in different pharmaceutical products intended for hepatitis C infections.
