Beta Blockers' Angina Action

Decreases heart rate and contractility to reduce workload on the heart.

Nitrate Anti-Anginal Drug

Isosorbide mononitrate is a type of nitrate.

Ranolazine's Angina Benefit

Inhibits late sodium channels to decrease myocardial oxygen demand.

Calcium Channel Blocker Side Effect

Hypotension (low blood pressure) is a potential side effect.
