High-Yield Drug Classes for ATI Pharmacology
Cardiovascular Drugs
- Beta blockers (-olol): Metoprolol, atenolol. Lower HR and BP. Never stop abruptly. Monitor for bradycardia, hypotension, fatigue.
- ACE inhibitors (-pril): Lisinopril, enalapril. Lower BP, protect kidneys. Side effect: dry cough, hyperkalemia, angioedema. Avoid in pregnancy.
- Statins (-statin): Atorvastatin, simvastatin. Lower cholesterol. Monitor liver enzymes. Side effect: myopathy — ask about muscle pain.
- Digoxin: Treats heart failure and AFib. Narrow therapeutic index 0.5-2 ng/mL. Toxicity signs: nausea, yellow-green vision, bradycardia. Antidote: Digibind.
Anticoagulants
- Warfarin: Monitor INR (therapeutic 2-3). Antidote: Vitamin K. Many drug and food interactions — consistent vitamin K intake.
- Heparin: Monitor aPTT (therapeutic 60-100 seconds). Antidote: Protamine sulfate. Watch for HIT.
- Enoxaparin (Lovenox): Low molecular weight heparin. SubQ injection. No routine monitoring needed.
Antibiotics
- Penicillins (-cillin): Cross-allergy with cephalosporins. Ask about penicillin allergy before giving.
- Vancomycin: Monitor trough levels, renal function. Red man syndrome — slow the infusion.
- Fluoroquinolones (-floxacin): Avoid in children — damages cartilage. Tendon rupture risk in adults.
High Alert Medications
- Insulin — always double-check dose, know onset/peak/duration
- Opioids — monitor respiratory rate, have naloxone available
- Anticoagulants — bleeding precautions, monitor labs
- Chemotherapy — PPE required, handle with care
