1.0 Abstract: A sensitive and precise stability indicating RP-HPLC method was developed and validated for the simultaneous determination of known related substances, isomer-I(RRT 0.85), isomer-II(RRT 1.13) and other unknown related substances of nebivolol in nebivolol tablets. The chromatographic separation was performed on Hypersil BDS Phenyl (250mm x 4.6mm) 5μm, using isocratic elution of buf...
1.1 introduction “i see translation as the attempt to produce a text so transparent that it does not seem to be translated. a good translation is like a pane of glass. you only notice that it’s there when there are little imperfections- scratches, bubbles. ideally, there shouldn’t be any. it should never call attention to itself.” “norman shapiro” (venuti, 1995:1) edward fitzgerald is the br...
Liquid chromatographic method was developed for simultaneous quantitative determination of dicyclomine hydrochloride, mefenamic acid and paracetamol in their combined dosage form. The separation was achieved using a C18 column (250×4.6 mm id, 5 μm) using acetonitrile:20 mM potassium dihydrogen phosphate 70:30 (v/v) adjusted to pH 4 using orthophosphoric acid as mobile phase at a flow rate of 1 ...
The objective of the study was to develop a simple, specific and stability-indicating HPLC method for the simultaneous determination of creatine phosphate sodium (CPS) and its related substances in pharmaceutical formulation. Separation of creatine phosphate sodium from its major process impurities and degradation products was achieved on a Hypersil BDS C18 column (250 × 4.6 mm, 5 μm) with an a...
Background: Intravenous regional anesthesia (IVRA) is an efficient method for short-term procedures of the upper extremities. Some defects are associated with IVRA including tourniquet-related pain and insufficient duration of the anesthesia. The main purpose of the current study was to compare the effects of adding paracetamol or magnesium sulfate to lidocaine in IVRA on pain, venous blood gas...
