Clinical Pharmacy and Therapeutics
Core Concepts
Clinical pharmacy applies drug knowledge to patient care. Candidates must understand disease management (e.g., hypertension, diabetes, asthma), therapeutic guidelines, and individualization of therapy based on age, renal/hepatic function, and genetics. Key skills include medication reconciliation, therapeutic drug monitoring (TDM), and patient education. Drug interactions and contraindications are frequently tested.
Question Traps
- First-line vs. add-on therapy: Guidelines specify first-line agents (e.g., metformin for type 2 diabetes; ACE inhibitors for hypertension with diabetes).
- Renal dosing: Many drugs require dose adjustment in renal impairment (e.g., gentamicin, enoxaparin).
- TDM: Monitor drugs with narrow therapeutic index (e.g., digoxin, vancomycin, phenytoin).
Worked Example / Rule of Thumb
Question: A patient with asthma uses a short-acting beta-agonist (SABA) more than twice weekly. What is the next step? Add a low-dose inhaled corticosteroid (per GINA guidelines). Rule of thumb: “Treat the underlying inflammation” – SABA relieves symptoms but does not control inflammation.
