Antidysrhythmic properties-Physiological calcium channel blocker. Reduces SA node impulse formation, prolongs conduction time in myocardium
Anticonvulsant properties-reduces striated muscle contractions and blocks peripheral neuromuscular transmission by reducing acetylcholine release at the myoneural junction |

Incompatible with alcohol, salicylates, sodium bicarb
Additive effects can occur with other CNS depressants
Concurrent use with nifedipine in the trx of maternal hypertension can cause increased hypotension or pronounced muscle weakness and may harm the fetus
