A reverse phase HPLC method is developed for the determination of Raloxifene in pharmaceutical dosage forms. Chromatography was carried out on an inertsil C18 column using a mixture of acetonitrile and phosphate buffer (30:70 v/v) as the mobile phase at a flow rate of 1 mL/min. Detection was carried out at 290 nm .The retention time of the drug was 10.609 min. The method produced linear responses in the concentration range of 0.5-200 µg/mL of Raloxifene. The method was found to be applicable for determination of the drug in tablets.

Abstract For type 2 diabetes treatment, combinations of drugs from the thiazolidinedione and sulfonylurea groups are now available in the same tablet or capsule. Therefore, a stability-indicating and validated HPLC method was developed for simultaneous determination of pioglitazone, rosiglitazone, and glipizide in combined dosage forms. The examined drugs were subjected to different conditions such as acid and base, temperature, and UV light, and degradation of pioglitazone and glipizide was observed under thermal and acidic stress. However, selectivity of the presented method for pioglitazone, rosiglitazone, and glipizide assay against their degradation products was confirmed. It was also demonstrated to be robust, resisting small deliberate changes in pH of the buffer, flow rate, and percentage of acetonitrile in the mobile phase. The presented method utilizes a LiChrospher RP18 column (125 4.0 mm), acetonitrile in phosphate buffer at pH 4.3 (40 + 60, v/v) as the mobile phase, and UV detection at 225 nm for pioglitazone/glipizide or 245 nm for rosiglitazone/glipizide. The method was validated with respect to linearity, precision, and accuracy. Finally, the elaborated procedure was applied for the QC of pioglitazone/glipizide and rosiglitazone/glipizide mixtures.

A novel approach was used to develop and validate a rapid, specific, accurate and precise Reverse phase High performance liquid chromatographic (RP-HPLC) method for the simultaneous determination of Metformin and Sitagliptin in pharmaceutical dosage forms and its applications to dissolution study. The chromatographic separation was carried out on a C8 (250mm X 4.6 mm i.d., 5μm) column with a mobile phase of 40 Acetonitrile: 60 Phosphate Buffer (pH 6.8), using UV detector at 257 nm at 1ml min-1 flow rate. The retention time for Metformin was 2.11 minutes and 5.30 minutes for Sitagliptin. The Linearity for Metformin was found to be 10-80 µg ml-1 with R2 value of 0.9998 and for Sitagliptin 1-8 µg ml-1 with R2 value of 0.9976. Dissolution study of both for Metformin and Sitagliptin was carried, Percentage of drug release was established which was found to be 96.23% and 102.64% respectively, in the period of 50 minutes.

A simple, rapid, precise, and accurate RP-HPLC method for the estimation of Ivabradine Hydrochloride an anti-anginal agent, both as a bulk drug and in pharmaceutical formulation was developed. The chromatographic separation was achieved on a Thermosil C18 150 × 4.5 mm, 5μm column by using a mobile phase containing a mixture of methanol and phosphate buffer pH 6.5 in the ratio of 65:35 % v/v at a flow rate of 1ml/min and at an ambient temperature. The detection was monitored at a wavelength of 265nm. A clear chromatographic peak was identified with the retention time of 4.36 min and tailing factor of 1.23. The developed method was validated according to ICH guidelines with respect to specificity, linearity, accuracy, precision and robustness. The method shows a good linear relationship with correlation co-efficient of more than 0.992 in the concentration range of 30μg-150μg. The method showed mean % Recovery of 100.4% and %RSD for repeatability and intermediate precision was less than 2%. The proposed method can be used successfully for the quantitative determination of Ivabradine HCL in pharmaceutical dosage forms.
