College Answer

Most candidates managed to provide a classification of calcium anatagonists. The 
pharmacology of verapamil was less well understood. The structure for answering a 
pharmacology question was often poor and there was commonly a lack of precision in 
pharmacokinetics. We suggest that candidates look at a general pharmacokinetic structure
when answering these questions. One approach would be a structure that covers drug name 
and description, pharmaceutics (chemistry/ ampoule contents), Pharmacokinetics, 
Pharmacodynamics (Think CNS/CVS/Resp/GIT etc. if relevant), Dose and Side effects then 
Indications and Contraindications can help organize the information
