Drug Designing: Open Access is a scientific open access journal that specifies and describes the development activities conducted in the fields of including molecular modeling, clinical research and drug discovery and delivery.

Journal accepts original manuscripts in the form of research articles, review articles, Clinical reviews, commentaries, case reports, perspectives and short communications.

The journal focuses on all fields of drug design including drug discovery, drug design by rational approach, target-based design, drug synthesis, drug metabolism, structure-based drug design, molecular modeling, ligand-based interaction, development of the generic drug, in silico chemoinformatics and bioinformatics technologies, receptor agonist/antagonist, protease substrate/inhibitor, peptidomimetic, Quality by design, Design for reliability in drug development, Design for traditional Chinese medicine clinical trials, Bayesian sequential design for multi-regional design, Design and analysis for target clinical trials, Design and analysis for diagnostic procedures, Adaptive design for early clinical development, Design for biosimilar studies, Design for bioassay development and validation, Design for statistical genetics, Design for assessment of drug to drug interaction, Design for bridging studies, Design for stability analysis.

This method was developed to determine the enantiomeric purity of some products of esomeprazole (capsules, tablets) manufactured locally and in some neighboring countries for the determination the percentage of R enantiomer. A product of under license company was used for comparison of the results. The study was performed by using a validated HPLC method on chiral column Nucleocel Alpha Sand a mixture ethanol: hexane (70:30, v/v) as a mobile phase, the flow rate was 0.65 ml/min, and the detection was carried out using UV detector at 302nm. The temperature of column was set at 25C. The study showed that some samples were not polluted with R enantiomer, while the others contained this enantiomer in the range of 0.1-2.24%.
