What is the difference between anti cholinergic and cholinergic drugs?

Cholinergic agents allow you to see due to the production of fluid that moisturizes the eyes and you can salivate because of the production of mucus. You can also urinate and defecate. Anticholinergic agents decrease all the activities mentioned above.

What is a cholinergic drug do?

Cholinergic drug, any of various drugs that inhibit, enhance, or mimic the action of the neurotransmitter acetylcholine, the primary transmitter of nerve impulses within the parasympathetic nervous system—i.e., that part of the autonomic nervous system that contracts smooth muscles, dilates blood vessels, increases …

What is another name for cholinergic drugs?

Examples of direct-acting cholinergic agents include choline esters (acetylcholine, methacholine, carbachol, bethanechol) and alkaloids (muscarine, pilocarpine, cevimeline). Indirect-acting cholinergic agents increase the availability of acetylcholine at the cholinergic receptors.

Is sympathetic adrenergic or cholinergic?

The postganglionic neuron for the sympathetic division is usually an adrenergic neuron which means that it produces norepinephrine (NE) as its neurotransmitter. Sympathetic postganglionic neurons innervating sweat glands and some blood vessels are the exception-; they are cholinergic and release ACH.

How do adrenergic receptors and cholinergic receptors differ?

The key difference between adrenergic and cholinergic receptors is that the adrenergic receptors are G protein -coupled receptors that bind to the neurotransmitters noradrenaline (norepinephrine) and adrenaline (epinephrine) while the cholinergic receptors are inotropic and metabotropic receptors that bind to acetylcholine neurotransmitters.

How can adrenergic drugs stimulate the adrenergic nerves?

Adrenergic drugs stimulate the adrenergic nerves directly by mimicking the action of norepinephrine or indirectly by stimulating the release of norepinephrine. Therapeutically, these drugs are used to combat life-threatening disorders, which include acute attacks of bronchial asthma, shock, cardiac arrest, and allergic reactions.

What do cholinergic blockers do to the pupil?

Cholinergic blockers keep the sphincter muscle of the iris from contracting. The result is dilation of the pupil (mydriasis) and paralysis of the ocular lens (cycloplegia). This can be detrimental to patients with glaucoma because it results in increased intraocular pressure (see Chapter 57).

What do adrenergic antagonists mean?

An adrenergic antagonist is a drug that inhibits the function of adrenergic receptors. There are five adrenergic receptors, which are divided into two groups. The first group of receptors are the beta (β) adrenergic receptors.
