Mechanism of action
Diltiazem works by inhibiting the calcium channels in the heart muscles and blood vessels, which helps in the relaxation and dilation of the blood vessels and increases the amount of blood and oxygen that can reach the heart. It lowers blood pressure and lessens the possibility of angina.
It could result in lightheadedness, nausea, weakness, flushing, constipation, headaches, dizziness, and fast heart rate.
