Nifedipine There are two basic types of calcium channel blockers: dihydropyridine and non-dihydropyridine. The most important difference between the two types is that non-dihydropyridine calcium channel blockers can slow down the heart rate, while dihydropyridine calcium channel blockers do not. Nifedipine is a dihydropyridine calcium channel blocker, which means that it does not usually decrease the heart rate.

Calcium antagonist and the peripheral circulation: differences and similarities between PY 108-068 nicardipine, verapamil and diltiazem Abstract. 1 The effects of two dihydropyridines, PY 108-068 (PY) and nicardipine (N), and two other calcium antagonists, verapamil (V) and diltiazem (D), on regional blood flow were measured in open-chest cats, anaesthetized with chloralose-urethane.2 Each substance was infused at 3 different dose rates, each for 10 min. Blood flow to stomach and small intestine was only slightly increased. Flow to the kidneys increased slightly in diltiazem-treated animals but did not change with all other treatments. Flow to the liver, the adrenals, and the spleen remained unchanged or showed a tendency to decrease.

Varenicline Varenicline (trade name Chantix and Champix usually in the form of varenicline tartrate), is a prescription medication used to treat nicotine addiction. Varenicline is a nicotinic receptor partial agonist—it stimulates nicotine receptors more weakly than nicotine itself does. In this respect it is similar to cytisine and different from the nicotinic antagonist, bupropion, and nicotine replacement therapies (NRTs) like nicotine patches and nicotine gum.

Muscarinic antagonist A muscarinic receptor antagonist (MRA) is an agent that blocks the activity of the muscarinic acetylcholine receptor.Acetylcholine (often abbreviated ACh) is a neurotransmitter, whose receptor is a protein found in synapses and other cell membranes.t higher-than-therapeutic doses, atropine and scopolamine cause CNS depression characterized by amnesia, fatigue, and reduction in rapid eye movement sleep. Scopolamine (Hyoscine) has anti-emetic activity and is, therefore, used to treat motion sickness. Antimuscarinics are also used as anti-parkinsonian drugs.
