This top-selling medical pharmacology study tool is now in its Second Edition. Targeted for second year medical students to review and prepare for the USMLE Step 1, these updated cards are organized by mechanism, and feature a template format that conveys information needed for learning and retaining the pharmacology concepts as well as for memorization. Five new cards are added to comprise a section, Fundamentals of Pharmacology, plus 50 additional drugs are covered. Other revisions include renaming Side Effects to Adverse Effects, and inclusion of chemical structures retained only where a clear connection to the mechanism applies.
