Side effects of these drugs may include but are not limited to: Constipation; Peripheral edema, which can occur in as much as 70% of people receiving calcium channel blocker, is caused by calcium channel blockers' preferential arteriolar or precapillary dilation without commensurate dilation in the venous or postcapillary circulation.
Potassium channel blockers exhibit reverse use-dependent prolongation of the action potential duration. Reverse use dependence is the effect where the efficacy of the drug is reduced after repeated use of the tissue. [11] This contrasts with (ordinary) use dependence, where the efficacy of the drug is increased after repeated use of the tissue.
Sodium channel blockers are also used as local anesthetics and anticonvulsants. [5] Sodium channel blockers have been proposed for use in the treatment of cystic fibrosis, [6] but current evidence is mixed. [7] It has been suggested that the analgesic effects of some antidepressants may be mediated in part via sodium channel blockade. [8]
Isradipine (tradenames DynaCirc, Prescal) is a calcium channel blocker of the dihydropyridine class. It is usually prescribed for the treatment of high blood pressure in order to reduce the risk of stroke and heart attack. It was patented in 1978 and approved for medical use in 1989. [1]
Calcium channel blocker toxicity is the taking of too much of the medications known as calcium channel blockers (CCBs), either by accident or on purpose. [3] This often causes a slow heart rate and low blood pressure . [ 1 ]
It is a calcium channel blocker of the dihydropyridine type. [2] Nifedipine is taken by mouth and comes in fast- and slow-release formulations. [2] Common side effects include lightheadedness, headache, feeling tired, leg swelling, cough, and shortness of breath. [2] Serious side effects may include low blood pressure and heart failure. [2]
Verapamil, sold under various trade names, [1] is a calcium channel blocker medication used for the treatment of high blood pressure, angina (chest pain from not enough blood flow to the heart), and supraventricular tachycardia. [9]
The side effects could be severe dizziness, fast heartbeat, and swelling of face, lips, tongue, eyelids, hands and feet. Lesser side effects include stomach pain, diarrhea and hypotension. Peripheral edema , a common side effect from the use of amlodipine , was reduced when patients were shifted to cilnidipine.
