Adrenergic drug, any of various drugs that mimic or interfere with the functioning of the sympathetic nervous system by affecting the release or action of norepinephrine and epinephrine adrenergic drugs that produce or inhibit these effects are known as sympathomimetic agents and sympatholytic agents, respectively.
Parasympatholytic vs sympathomimetic drug sign in to follow this sympathomimetic parasympathomimetic specificity of the drug as to which one is used ie which receptors it works on in order to bring about a specific effect there are cases where the drugs are not interchangable and this is because of differences in sympathetic. A parasympathomimetic drug, sometimes called a cholinomimetic drug, is a substance that stimulates the parasympathetic nervous system (psns) these chemicals are also called cholinergic drugs because acetylcholine (ach) is the neurotransmitter used by the psns.

The effects of the drugs were additive to test this hypothesis the effects of a parasympathomimetic drug (carbachol) and a sympathomimetic drug (isoproterenol) on nett electrolyte transport and. In patients using parasympathomimetic agents (eg, pilocarpine), aphose can result from miosis41 in patients using sympathomimetic agents (eg, dipivefrine), dilated pupils resulted in photophobia and blurred vision therefore, a test drop was generally administered in the clinic and the patient was observed for adverse reactions before.
Drugs that enhance cholinergic effects are called parasympathomimetic drugs, whereas those that inhibit cholinergic effects are referred to as anticholinergic drugs pilocarpine is a nonspecific muscarinic agonist commonly used to treat disorders of the eye. The effect of a sympatho- and a parasympathomi- metic drug on the electrolyte concentrations of primary and final saliva of the rat s~abmaxillary.

General pharmacology sympathomimetic drugs mimic the effects of sympathetic activation on the heart and circulation like the sympathetic nerves innervating the heart, sympathomimetics stimulate the heart through activation of beta-adrenoceptors, and sympathomimetics cause vascular smooth muscle contraction and vasoconstriction through activation of alpha-adrenoceptors. Parasympathomimetic drugs also called as cholinomimetic or cholinergic drugs, these are actually the drugs which produce effects same as those produced by the incitement of parasympathetic nervous system on the particular organs.
Hence effect of sympathomimetic and parasympathomimetic drugs on intestinal motility can be studied by using isolated piece of intestine parasympathomimetic drugs stimulate enteric neurons to release acetylcholine at neuromuscular junctions and enhance muscle tone and rhythmicity of intestine.

Sympathomimetic agents – those whose actions tend to augment or exaggerate the effects of the sympathetic nervous system – have a long history in modern medicine in the 1920s, ephedrine was extracted from ephedra species, and amphetamine became the first drug marketed specifically to treat depression ( rasmussen, 2006 .

Parasympathomimetic any effect similar to that produced by stimulation of the parasympathetic nervous system, especially the effect of cholinergic drugs see also sympathomimetic parasympathomimetic an agent whose effects mimic those resulting from stimulation of the parasympathetic nerves. Explain the difference between reversible anticholinestease drugs and irreversible parasympathomimetic drugs reversible: the effect wears off in mins-hours because the drug is released from enzyme and activities restored.
Inhibit acetylcholinesterase by binding to its anionic/esteratic site, thus preventing destruction of acetylcholine, increase synaptic levels of ach, stimulate more receptors and prolong and intensify ach effects on cholinergic receptors.
