By: Ronik Saha, Pharm.D. Candidate c/o 2013 – Clopidogrel (Plavix®) is a thienopyridine antiplatelet agent, which exerts its antiplatelet effects via in vivo conversion to an active thiol metabolite that irreversibly blocks the P2Y-12 component of platelet ADP receptors.  This prevents activation of the GP2B/3A complex, thereby preventing platelet aggregation.  Along with aspirin, clopidogrel reduces…

By: Neal Shah – Osteoporosis is a disease of the bone characterized by decreased bone mineral density (BMD), which reduces the ability of bone to provide adequate structural support.  The main cause of this decreased BMD is inadequate calcium intake or absorption.  The decreased BMD can cause diffuse lesions throughout the skeletal system and can…
