A novel, precise, accurate, rapid and cost effective isocratic reverse-phase high performance liquid chromatographic (RP-HPLC) method was developed, optimized and validated for the estimation of Arterolane maleate and Piperaquine phosphate in pharmaceutical dosage forms (tablet). The drugs were estimated using hypersil C18 (250 mm x 4.6 mm i.d- 5 µm particle size) column. A mobile phase composed of phosphate buffer, acetonitrile, methanol in proportion of 40:30:30 v/v, at a flow rate of 1.0 ml/min was used for the separation. Detection was carried out at 244 nm. The linearity range obtained was 20-70 µg/ml for ART and 100-350 µg/ml for PIP with retention times (Rt) of 3.353 min and 2.389 min for ART and PIP respectively. The correlation coefficient values were found to be 0.999. Precession studies showed % RSD values less than 2 % for both the drugs in all the selected concentrations. The percentage recoveries of ART and PIP were in the range of 99.47-100.72% and 99.30-100.18% respectively. The assay results of ART and PIP were 99.57% and...

The plethora of drug therapies and types of drugs demand different formulations, fabrications conditions and release kinetics. No single polymer can satisfy all the requirements. Therefore, there have been tremendous advances in area of biodegradable copolymers over the last 30 years. This article reviews current research on biodegradable polymers, focusing their potential as drug carries. The major classes of polymers are briefly discussed with regard to synthesis, properties and biodegradability, and known degradation modes and products are indicated based on studies reported in the literature. A vast majority of biodegradable polymers studied belongs to the polyester family, which includes polyglycolides and polylactides. Other degradable polymers such as polyorthoesters, polyanhydrides and polyphosphazenes are also discussed and their advantages and disadvantages are...

The objective of this review was to bring a chemicophysical approach towards dendrimers in different aspects including host-guest interaction and drug targeting. These nanosizedz polymeric molecules are unique in structural properties which have made dendrimers a potential candidate to lend itself as a carrier for drugs and bioactive molecules. Dendrimers offer the coupling of guest molecules by several phenomena including internal complexation and topological complexation forming catenanes and rotaxanes. Surface binding of guest molecules are achieved by coupling with the multiple surface binding groups. The physical attributes like size, shape, molecular weight and surface charge are modified for internalization of dendrimers into the specific cells by passive targeting mode. The polymer-drug couples are linked to targeting ligands for their active targeting by receptor mediated endocytosis. The binding and dissociation kinetics of such molecules can be tuned according to the desired retention time in a biological...
