Context: Rosuvastatin is a cholesterol lowering drug. It belongs to class statin. It is prescribed to the patients of coronary artery disease; atherosclerosis; thrombosis; increased low-density-lipoprotein; lipid and triglyceride. Aims:It is a newer drug in market and studies over the pharmacodynamics and pharmacokinetics are in progress. Statin therapy is a long term treatment for which its behavior in the presence of other agents is necessary. For this purpose present study is based on the interaction of the drug with essential and trace elements present in human body or co-administered during multivitamin therapy. Settings and Design: Complexes of rosuvastatin with Cd(II), Cr(II), Mn(II), Fe(III), Co(II), Ni(II) and Zn(II) i.e., metals commonly present in multivitamins, were synthesized in laboratory. Methanolic solution of rosuvastatin with metal chloride salts was reacted. Methods and Material: Reaction between drug and metals was carried out in thermostat at 80 oC for five hours with timely TLC monitoring for completion of reaction. These newly synthesized complexes were identified by IR and NMR spectroscopy and CHN elemental microanalysis and the structure of complexes was proposed. Results: Analyses suggest two molecules of rosuvastatin co-ordinate with the central metal atom through their carboxylic group. CS Chem3D ultra suggests square planner structure of the complex. Conclusions: Synthesis of compounds proposes that rosuvastatin can bind to metals as ligand through its pharmocophore site that may lead to reduced activity of drug and metal both. The study is precursor to in vitro and in vivo study of interaction of drug and metals.
