in this study 50 samples of ecstasy tablets seized in iran during the period of 2007 through 2008 were examined and their physical characteristics (appearance, marking, scored/not scored, color, weight, diameter, thickness) were determined. in order to determine the chemical characteristics of these tablets, color tests (marquis test, simon’s test, chen’s test and gallic acid test), thin layer ...

Aim: Numerous technologies have been used to control the systemic delivery of a pharmacologically active ingredient in a predetermined, predictable, and reproducible manner. One of the most interesting approaches is osmotically controlled oral drug delivery systems. By optimizing formulation and processing parameters, it is possible to develop osmotic systems to deliver drugs of diverse nature ...

Objective(s): The current studys goal is to develop and test a tramadol hydrochloride transdermal gel based on vesicular drug delivery approaches. Materials methods: Transferosomes were chosen as the colloidal carrier for preparation. Thin film hydration was used create transferosomes. obtained transferosomes characterised content, diameter, zeta potential, entrapment efficiency, invitro releas...

A simple, precise and accurate reversed-phase liquid chromatographic method has been developed for the simultaneous estimation of aceclofenac (ACF), paracetamol (PCM) and tramadol hydrochloride (TRM) in pharmaceutical dosage form. The chromatographic separation was achieved on a HiQ-Sil™ HS C18 column (250×4.6 mm i.d., 5 μm particle size), kromatek analytical column at ambient temperature. The ...
