2. Calcium channel blocker - Wikipedia

   en.wikipedia.org/wiki/Calcium_channel_blocker

   Unlike beta blockers, calcium channel blockers do not decrease the responsiveness of the heart to input from the sympathetic nervous system. Since moment-to-moment blood pressure regulation is carried out by the sympathetic nervous system (via the baroreceptor reflex ), calcium channel blockers allow blood pressure to be maintained more ...

3. L-type calcium channel - Wikipedia

   en.wikipedia.org/wiki/L-type_calcium_channel

   L-type calcium channel blocker drugs are used as cardiac antiarrhythmics or antihypertensives, depending on whether the drugs have higher affinity for the heart (the phenylalkylamines, like verapamil), or for the blood vessels (the dihydropyridines, like nifedipine). [5]

4. Dihydropyridine calcium channel blockers - Wikipedia

   en.wikipedia.org/wiki/Dihydropyridine_calcium...

   Compared with certain other L-type calcium channel blockers (for example those of the phenylalkylamine class such as verapamil) that have significant action at the heart, the dihydropyridine calcium channel blockers lower blood pressure mainly by relaxing the smooth muscle of the blood vessel walls. [3]

7. Cardiovascular agents - Wikipedia

   en.wikipedia.org/wiki/Cardiovascular_agents

   Calcium channel blockers (CCBs) preferentially block the L-type voltage-gated calcium channels to prevent the flow of calcium influx in the blood vessels and the heart, thereby reducing peripheral vascular resistance and cardiac output respectively. [10] Dihydropyridines (DHP): amlodipine, nifedipine, felodipine, nicardipine

8. T-type calcium channel - Wikipedia

   en.wikipedia.org/wiki/T-type_calcium_channel

   Calcium channel blockers (CCB) such as mibefradil can also block L-type calcium channels, other enzymes, as well as other channels. [4] Consequently, research is still being conducted to design highly selective drugs that can target T-type calcium channels alone.

9. Antiarrhythmic agent - Wikipedia

   en.wikipedia.org/wiki/Antiarrhythmic_agent

   Class IV agents are slow non-dihydropyridine calcium channel blockers. They decrease conduction through the AV node, and shorten phase two (the plateau) of the cardiac action potential. They thus reduce the contractility of the heart, so may be inappropriate in heart failure.
