Summary
Intravenous calcium can reverse the vasodilation and blood pressure lowering of nicardipine. Oral supplements at usual doses are unlikely to matter clinically.
What this interaction means in plain words
Calcium and Nicardipine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Calcium belongs to Gastrointestinal Tract; Nicardipine belongs to Cardiovascular.
Why it happens
Increased extracellular calcium opposes L-type calcium channel blockade (pharmacodynamic antagonism).
What to do
Monitor blood pressure when IV calcium is given with nicardipine and adjust the antihypertensive if needed. Routine oral calcium needs no change.
