A new, simple, accurate, precise and reproducible UV spectrophotometric method is being developed for the simultaneous estimation of amlodipine besylate, olmesartan medoxomil and hydrochlorthiazide in tablet dosage form. The stock solutions were prepared in methanol. The max for amlodipine besylate, olmesartan medoxomil and hydrochlorthiazide were 238.5nm, 256.5nm and 271.5nm respectively. The amlodipine besylate, olmesartan medoxomil and hydrochlorthiazide obeyed Beer's law in concentration range of 5-25ug/ml, 6-30ug/ml and 5-25ug/ml respectively. Results of analysis of simultaneous equation...

We carried out a QSAR study on benzotriazine derivatives & studied 28 potent GABAA receptor ligands; derivatives of benzotriazines, using a combination of various physicochemical, steric, electronic and thermodynamic descriptors to determine the quantitative correlation between binding affinity and structural features with potent anticonvulsant activity. Correlation between these properties and anticonvulsant activity was used to synthesize compounds possessing potent anticonvulsant activity. Most of the compounds showed an ability to inhibit the maximum electroshock (MES) and...
