Pharmacology of Antianginal Drugs_ A Comprehensive Overview

Pharmacology of Antianginal Drugs: A Comprehensive Overview

Antianginal drugs are a crucial class of medications used to manage angina pectoris, a condition characterized by chest pain due to reduced blood flow to the heart. This presentation will explore the pharmacological aspects of these drugs, their mechanisms of action, and their clinical applications.

Introduction to Angina

Definition and pathophysiology

Types of angina: stable, unstable, and variant (Prinzmetal's)

Goals of antianginal therapy

Classes of Antianginal Drugs

a) Nitrates

b) Beta-blockers

c) Calcium channel blockers

d) Other agents (e.g., ranolazine, ivabradine)

Nitrates

Mechanism of action: NO-mediated vasodilation

Pharmacokinetics and dosage forms

Clinical uses and side effects

Tolerance and strategies to prevent it

Beta-blockers

Mechanism: Reduction of heart rate and contractility

Subtypes: Cardioselective vs. non-selective

Pharmacokinetics and dosing

Clinical applications beyond angina

Adverse effects and contraindications

Calcium Channel Blockers (CCBs)

Mechanism: Inhibition of calcium influx

Subtypes: Dihydropyridines vs. non-dihydropyridines

Pharmacokinetics and dosing strategies

Clinical uses in angina and other cardiovascular conditions

Side effects and precautions

Newer Antianginal Agents

Ranolazine: Mechanism and clinical use

Ivabradine: If inhibitor and its role in angina management

Combination Therapy

Rationale for combining different classes
