Abstract

A simple, accurate and precise spectroscopic method was developed for simultaneous estimation of Clopidogrel Bisulphate and Irbesartan in synthetic mixture using simultaneous equation Method. In this spectroscopic method, for Clopidogrel Bisulphate 220.00 nm and 250.00 nm wavelengths were selected for measurement of absorptivity. Both the drugs show linearity in a concentration range of 10-50 μg/ml at their respective λmax with correlation coefficient (r2) of 0.9996 and 0.9998 for Clopidogrel Bisulphate and Irbesartan, respectively. Accuracy, precision and recovery studies were done by QC samples covering lower, medium and high concentrations of the linearity range. The relative standard deviation for accuracy, precision studies were found to be within the acceptance range (< 2%). The limit of determination was 0.243 μg/ml and 0.323 μg/ml for Clopidogrel Bisulphate and Irbesartan, respectively. The limit of quantification was 0.737 μg/ml and 0.980 μg/ml for Clopidogrel Bisulphate and Irbesartan, respectively. Recovery of Clopidogrel Bisulphate and Irbesartan were found to be 99.57 % and 99.68 % respectively confirming the accuracy of the proposed method. % Assay was found to be 99.41 % and 99.22 % for Clopidogrel Bisulphate and Irbesartan, respectively. The proposed method is recommended for routine analysis since they are rapid, simple, accurate and also sensitive and specific by no heating and no organic solvent extraction.

Abstract

Stability of Donepezil Hydrochloride(DONE) was investigated using stability indicating Reverse phase high performance liquid chromatography (RP-HPLC) utilizing C-18 column and mobile phase containing Acetonitrile: Water (pH 3.5) in ratio of 40:60 at flow rate of 1 ml min-1. Peaks of donepezil and degradation products were well resolved at retention times < 7 min. Stability was performed in 0.1N hydrochloric acid, 0.1N sodium hydroxide, 3 % hydrogen peroxide, neutral, photolytic and dry heat conditions. Fast hydrolysis was seen in alkaline condition as compared to oxidative and neutral conditions. Methods was validated with respect to linearity, precision, accuracy, specificity and robustness LOQ and LOD. It was also found to be stability indicating, and therefore suitable for the routine analysis of Donepezil hydrochloride in the pharmaceutical formulation.

An approach of forced degradation study was successfully applied for the development of a stability-indicating high performance liquid chromatographic method for Indapamide in the presence of its degradation products. In the present study a simple, accurate and precise reverse phase liquid chromatographic method has been developed of Olmesartan Indapamide in bulk. Developed Method was achieved on symmetry C18 (150 mm × 4.6 mm, 5 μ) column using a Acetonitrile: 0.02 M Na2HPO4(45:55 v/v) mobile phase and pH 7 adjusted with ortho phosphoric acid. Isocratic elution mode at a flow rate of 1.0 ml/min at Room temperature with a load of 20μl Injection volume. The detection was carried out at 240 nm. The linearity of the proposed method was investigated in the range of 10-50 microg/mL (r2 = 0.998) for Indapamide. The retention time of Indapamide was found to be around 4.79 min and 7.59 min respectively.

Abstract

The present manuscript describe simple, sensitive, rapid, accurate, precise and economical first derivative spectrophotometric method for the simultaneous determination of Irbesartan (IRB) and Atorvastatin (ATR) in synthetic mixture. The derivative spectrophotometric method was based on the determination of both the drugs at their respective zero crossing point (ZCP). The first order derivative spectra was obtained in methanol and the determinations were made at 225.20 nm (ZCP of Atorvastatin) for Irbesartan and 308.15 nm (ZCP of Irbesartan) for Atorvastatin. The linearity was obtained in the concentration range of succinate 5-30 μg/ml for Irbesartan and 5- 30 μg/ml for Atorvastatin Succinate. The mean recovery was 99.25 and 99.65% for Irbesartan and Atorvastatin succinate, respectively. The method was found to be simple, sensitive, accurate and precise and was applicable for the simultaneous determination of Irbesartan and Atorvastatin in synthetic mixture. The results of analysis have been validated statistically and by recovery studies. The proposed method is recommended for routine analysis since they are rapid, simple, accurate and also sensitive and specific by no heating and no organic solvent extraction.

Abstract

This review article presents the pharmacology of combined treatment of Aripiprazole and Escitalopram oxalate in treatment of Major Depressive Disorders. Aripiprazole is anti psychotic agent. Escitalopram Oxalate is also an antidepressant agent (Selective Serotonin Reuptake Inhibitor). Aripiprazole's antipsychotic activity is likely due to a combination of antagonism at D2 receptors in the mesolimbic pathway and 5HT2A receptors in the frontal cortex. Antagonism at D2 receptors relieves positive symptoms while antagonism at 5HT2A receptors relieves negative symptoms of schizophrenia. Escitalopram Oxalate is selective serotonin reuptake inhibitors (SSRIs) are a group of chemically diverse antidepressant drugs that specifically inhibit serotonin reuptake. The SSRIs block the reuptake of serotonin, leading to increased concentrations of the neurotransmitter in the synaptic cleft and, ultimately, to greater postsynaptic neuronal activity. The combination of both have decrease dose and improve Depression. Combination of both the drugs were approved by us government and has been used in Major Depressive Disorders. The main objective of this review article is to provide pharmacological information of combined therapy of of Aripiprazole and Escitalopram Oxalate to researcher in development of combined dosage form of this.
