Study Notes
Calcium Channel Blockers (CCBs)
- CCBs block voltage-gated calcium (Ca²⁺) channels, influencing cardiac and vascular activity.
- Classification based on tissue selectivity:
- Cardiac Effects: Verapamil, Diltiazem
- Vascular Effects (Dihydropyridines): Nifedipine, Amlodipine, Nimodipine, Nicardipine
- Effects on Other Tissues: Flunarizine, Cinnarizine
Pharmacological Effects
-
Cardiovascular System (CVS):
-
Negative inotropic effects:
- Nifedipine: No effect
- Diltiazem: Moderate effect
- Verapamil: Strong effect
-
A-V conduction:
- Nifedipine: No effect
- Diltiazem: Decreases conduction
- Verapamil: Significantly decreases conduction
-
Heart Rate (HR):
- Nifedipine: Increases (reflex tachycardia)
- Diltiazem: Decreases
- Verapamil: Strongly decreases
-
Negative inotropic effects:
-
Blood Vessels:
-
Coronary Vasodilation:
- Nifedipine: Strong
- Diltiazem: Moderate
- Verapamil: Moderate
-
Peripheral Vasodilation:
- Nifedipine: Strong
- Diltiazem: Moderate
- Verapamil: Moderate
-
Blood Pressure Reduction:
- Nifedipine: Strong
- Diltiazem: Moderate
- Verapamil: Moderate
-
Coronary Vasodilation:

Other Effects:
- Relaxation of smooth muscles across various systems (vascular, bronchial, gastrointestinal, uterine).
- Reduction of calcium-mediated cell necrosis and apoptosis.
- Verapamil affects pancreatic beta-cell insulin release minimally clinically.
Therapeutic Uses
-
Cardio-selective CCBs (Verapamil & Diltiazem):
- Used in ischemic heart disease (IHD) to reduce myocardial contractility and oxygen demand, improve coronary blood flow, and decrease myocardial necrosis.
-
Vasculo-selective CCBs (Dihydropyridines like Nifedipine):
- Effective in managing arterial hypertension and peripheral vascular diseases (e.g., Raynaud's disease) while improving peripheral microcirculation.
- Nifedipine can relax the uterus and delay preterm labor.
- Nimodipine specifically prevents cerebral vasospasm and ischemia after subarachnoid hemorrhage.
Adverse Effects
-
Verapamil & Diltiazem:
- Bradycardia and heart block.
- Worsening of congestive heart failure due to negative inotropic effects.
- Constipation linked to reduced gastrointestinal motility.
-
Nifedipine:
- Hypotension and reflex tachycardia.
- Gingival hyperplasia.
- Salt and water retention causing ankle edema, more common than with Verapamil.
Contraindications & Precautions
-
Verapamil & Diltiazem:
- Contraindicated in congestive heart failure and significant bradycardia or heart block.
- Caution in Wolff-Parkinson-White (WPW) syndrome, where abnormal conduction pathways may worsen tachycardia under CCB influence.
- Clinical management for WPW includes amiodarone, but definitive treatment is accessory pathway ablation.
