objective(s): response surface methodology (rsm) by central composite design (ccd) was applied to statistically optimize the preparation of rutin-quercetin (ru-qr) dual drug loaded human hair keratin nanoparticles as well as evaluate the characteristics. materials and methods: the effects of three independent parameters, namely, temperature (x1:10-40 c), surfactant (x2: sds (1), sls (2), tween-...

the objective of present research was to design, evaluate and compare drug release from two different dosage forms in pulsatile drug delivery system (dds) for metoprolol tartarate (mt) as tablet and capsule. pulsatile systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal delivery ...

Initially, the design of new drugs was based on the prototypical molecule, usually a natural product and making structural modifications. For designing of new drugs the understanding of the etiology of the disease and the structure of the receptor where the ligand (drug) will bind is very much important. Now a day, there is increasing computational power coupled with applicable software, has le...

Previous analysis of systems pharmacology has revealed a tendency of rational drug design in the pharmaceutical industry. The targets of new drugs tend to be close with the corresponding disease genes in the biological networks. However, it remains unclear whether the rational drug design introduces disadvantages, i.e. side effects. Therefore, it is important to dissect the relationship between...

In the field of pharmaceutical sciences, the drug discovery is an interdisciplinary approach by which new potential drug candidates are discovered. Traditionally, new drug molecules were discovered through identifying the active principles from natural sources or by serendipitous discovery. But it was time consuming and expensive. As a result, in the last few years there has been a technologica...

In the last years, considerable progress has been made concerning efficient drug design by in silico adapting drug molecule candidates to known binding sites that had been spatially elucidated by methods of structural biology. This allows identification of suitable ligands with regard to both geometry of the binding pocket and affinity as deduced from knowledge of docking points and energy calc...

Objective(s): A Box-Behnken design was used for evaluation of Eudragit coated diclofenac pellets. The purpose of this work was to optimize diclofenac pellets to improve the physicochemical properties using experimental design. Materials and Methods: Diclofenac was loaded onto the non-pareil beads using conventional coating pan. Film coating of pellets was done at the same pan. The effect of pla...
