Analytical chemistry is the science that seeks ever improved means of measuring the chemical composition of natural and artificial materials.Netupitant Delayed emesis has been largely associated with the activation of tachykinin family neurokinin 1 receptors. Palonosetron is a selective serotonin 5-HT3 receptor antagonist. The antiemetic activity of the drug is brought about through the inhibition of 5-HT3 receptors present both centrally and peripherally in turn inhibits the visceral afferent stimulation of the vomiting center.The mobile phase used was orthophosphoric and acetate 70% buffer pH 3 and 30% methanol.The assay of Netupitant and Palanosetron was performed with tablets and the % assay was found to be 100.08 and 100.04, The linearity was found to be linear with a correlation coefficient of 0.999, the precision 0.8 and 0.3 for Netupitant and Palanosetron which shows that the method is precise.The validation of developed method shows that the accuracy is well within the limit, which shows that the method is capable of showing good accuracy and reproducibility. The LOD and LOQ for Netupitant were found to be 3.02 and 9.98 and LOD and LOQ for Palanosetron was found to be 3.00 and 10.00. Thus, it shows that the method is stability indicating, sensitive, accurate, robust and precise. Hence, the developed HPLC method can be successfully applied to the pharmaceutical dosage form and can be used for routine analysis.

A simple, rapid, precise, sensitive and reproducible reverse phase high performance liquid chromatography (RP-HPLC) method has been developed for the quantitative analysis of Dolutegravir and Rilpivirine in pharmaceutical dosage form. Chromatographic separation of Dolutegravir and Rilpivirine was achieved on Waters Alliance -2695, by using Luna C18 (250mm x 4.6mm, 5µm) column and the mobile phase containing 0.1% OPA & ACN in the ratio of 50:50 v/v. The flow rate was 1.0 ml/min, detection was carried out by absorption at 245 nm using a photodiode array detector at ambient temperature. The number of theoretical plates and tailing factor for Dolutegravir and Rilpivirine were NLT 2000 and should not more than 2 respectively. The linearity of the method was excellent over the concentration range 10-150 µg/ml and 5-75 µg/ml for Dolutegravir and Rilpivirine respectively. The correlation coefficient was 0.999. % Relative standard deviation of peak areas of all measurements always less than 2.0. The proposed method was validated according to ICH guidelines. The method was found to be simple, economical, suitable, precise, accurate & robust method for quantitative analysis of Dolutegravir and Rilpivirine study of its stability.

Chromatogram was run through Std Discovery C8 150 x 4.6 mm, 5m. Mobile phase containing Buffer 0.1% OPA: Acetonitrile taken in the ratio 60:40 was pumped through column at a flow rate of 1 ml/min. Buffer used in this method was 0.1% OPA buffer. Temperature was maintained at 30°C. Optimized wavelength selected was 260 nm. Retention time of Sofosbuvir and Ledipasvir were found to be 2.367 min and 3.436 min. %RSD of the Sofosbuvir and Ledipasvir were and found to be 0.6 and 0.5 respectively. %Recovery was obtained as 99.61% and 99.80% for Sofosbuvir and Ledipasvir respectively. LOD, LOQ values obtained from regression equations of Sofosbuvir and Ledipasvir were 0.67, 2.02 and 0.70, 2.12 respectively. Regression equation of Sofosbuvir is y = 4266.x + 7700, and y = 4861.x + 2656.of Ledipasvir.

A simple, rapid, precise and accurate method is developed for the quantitative simultaneous determination of ceftriaxone and tazobactum in bulk and pharmaceutical formulations. Separation of ceftriaxone and tazobactum was successfully achieved by using Inertsil C18 ODS column 250X4.6mm, 5µm in an isocratic mode using water and acetonitrile (80:20) at a flow rate of 1.0 ml/min and was monitored at 254 nm with a retention time of 3.049 minutes and 4.317 minutes for ceftriaxone and tazobactum respectively. The method was validated and the response was found to be linear in the drug concentration range of 20µg/ml to 80 µg/ml for ceftriaxone and 5 µg/ml to 35 µg/ml for tazobactum. The values of the correlation coefficient were found to be 0.999 for ceftriaxone and 0.999 for tazobactum respectively. The LOD and LOQ for ceftriaxone were found to be 0.021 and 0.064 respectively. The LOD and LOQ for tazobactum were found to be 0.030 and 0.091 respectively. The percentage recovery for ceftriaxone and tazobactum were found to be 98-102% respectively which indicates that the proposed method is highly accurate. The specificity of the method shows good correlation between retention times of standard with the sample. The method was extensively validated according to ICH guidelines for Linearity, Accuracy, Precision, Specificity and Robustness. Stability of the drugs was determined by using acid/base, thermal, oxidative stress testing.

A simple, rapid and precise method was developed for the quantitative simultaneous determination of Omeprazole and Domperidone in combined pharmaceutical-dosage forms. The method was based on UV-Spectrophotometric determination of two drugs, using simultaneous equation method. It involves absorbance measurement at 291 nm (λmax of Omeprazole) and 289 nm (λmax of Domperidone) in Methanol: Acetonitrile (30:70 v/v). For UV Spectrophotometric method, linearity was obtained in concentration range of 1-15 µg/ml for Domperidone and 1-50 µg/ml for Omeprazole respectively, with regression 0.999 and 0.999 for Domperidone and Omeprazole respectively. Recovery was in the range of 99 -103%; the value of standard deviation and %R.S.D were found to be < 2 %; shows the high precision of the method., in accordance with ICH guidelines. The method has been successively applied to pharmaceutical formulation and was validated according to ICH guidelines.

A simple, rapid and precise method is developed for the quantitative determination of Fluoxetine in combined pharmaceutical-dosage forms. The method was based on UV Spectrophotometric determination of Fluoxetine drug using Beer-Lamberts Law. It involves absorbance measurement at 224 nm (λmax of Fluoxetine) in water. For UV Spectrophotometric method, linearity was obtained in concentration range of 5-30 mcg/ml with regression 0.999 for Fluoxetine respectively. Recovery was in the range of 98 -102%; the value of standard deviation and %R.S.D was found to be < 2 shows high precision of the method..
