Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists [2] are a group of medications that disrupt the movement of calcium (Ca 2+) through calcium channels. [3] Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension.
It is a calcium antagonist accompanied with L-type and N-type calcium channel blocking functions. Unlike other calcium antagonists, cilnidipine can act on the N-type calcium channel in addition to acting on the L-type calcium channel. It was patented in 1984 and approved for medical use in 1995.
ATC code C08 Calcium channel blockers is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. [1] [2] [3] Subgroup C08 is part of the anatomical group C Cardiovascular system ...
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]
Flunarizine is a selective calcium antagonist with moderate other actions including antihistamine, serotonin receptor blocking and dopamine D 2 blocking activity. Compared to other calcium channel blockers such as dihydropyridine derivatives, verapamil and diltiazem, flunarizine has low affinity to voltage-dependent calcium channels.
There are several different major classes of channel blockers, including: Calcium (Ca 2+) channel blockers; Chloride (Cl −) channel blockers; Potassium (K +) channel blockers; Sodium (Na +) channel blockers; The following types which act on ligand-gated ion channels (LGICs) via binding to their pore also exist: 5-HT 3 receptor antagonists
Verapamil is also a Kv voltage gated potassium channel blocker. [37] Calcium channels are also present in the smooth muscle lining blood vessels. By relaxing the tone of this smooth muscle, calcium channel blockers dilate the blood vessels. This has led to their use in treating high blood pressure and angina pectoris. The pain of angina is ...
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]
