a convenient liquid chromatographic-single quadrupole mass spectrometric (lc-ms) method was developed and validated for dexchlorpheniramine maleate (inn name: chlorphenamine) determination in human plasma. the need for just a single liquid-liquid extraction with ethyl acetate and being highly sensitive were the advantages of this method. the linearity was also excellent over the range of 1 to 1...
The paper describes the synthesis of pH sensitive interpenetrating polymeric network (IPN) beads composed of chitosan, glycine, glutamic acid, cross linked with glutaraldehyde and their use for controlled drug release. The drug was loaded into beads by varying their composition such as, amount of crosslinker glutaraldehyde, ratio of chitosan, glycine and glutamic acid. The beads were characteri...
The inhibitory effects of aqueous-ethanolic extracts of Crocus sativus (Iridaceae), on histamine (H1) receptors was examined on tracheal chains of guinea pigs. The effects of three concentrations of aqueous-ethanolic extract, 10 nM chlorpheniramine, and saline on histamine (H1) receptors were tested on three groups of guinea pig tracheal chains as follows; incubated trachea with: 1) indomethaci...
INTRODUCTION Calotropis procera is known to produce contact dermatitis and the latex of this plant produces intense inflammation when injected locally. However, the precise mode of its pro-inflammatory effect is not known. In present study we have pharmacologically characterized the inflammation induced by latex of C. procera in a rat paw edema model and determined the role of histamine in late...
Achillea wilhelmsii have been used in folk remedies. The relaxant effects of the extract of A. wilhelmsii on tracheal chains of guinea pigs were examined. The relaxant effects of four cumulative concentrations of the extract, theophylline and saline were examined by their relaxant effects on precontracted tracheal chains of guinea pig by KCl (group 1), 10 μM methacholine (group 2), incubated ti...
BACKGROUND AND THE PURPOSE OF THE STUDY The linear multivariate calibration models such as principal components regression (PCR) and partial least squares regressions (PLS1 and PLS2) due to the mathematical simplicity and physical or chemical interpretability are sufficient and generally preferred method for analysis of multicomponent drugs. In this study, simultaneous determination of paraceta...
