Neuropharmacology is the study of how drugs affect function in the nervous system, ... This increase in synaptic dopamine will increase binding to receptors of the ...
The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.
A stimulant is an overarching term that covers many drugs including those that increase the activity of the central nervous system and the body, [1] drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. [2] Sympathomimetic effects are those effects that mimic or copy the actions of the sympathetic nervous ...
A parasympathomimetic drug, sometimes called a cholinomimetic drug [1] or cholinergic receptor stimulating agent, [2] is a substance that stimulates the parasympathetic nervous system (PSNS). [3] [2] These chemicals are also called cholinergic drugs because acetylcholine (ACh) is the neurotransmitter used by the PSNS.
By acting on the receptors and acetylcholinesterase involved in transmission of nerve signals, autonomic drugs can be adopted to stimulate or inhibit the parasympathetic nervous system to achieve therapeutic effects. Promoting stimulation of the parasympathetic nervous system can be attained by using muscarinic agonists or anticholinesterase drugs.
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) antagonists and alpha-2 (α 2) agonists, which are used to treat high ...
Multiple effects on the immune system. The sympathetic nervous system is the primary path of interaction between the immune system and the brain, and several components receive sympathetic inputs, including the thymus, spleen, and lymph nodes. However, the effects are complex, with some immune processes activated while others are inhibited. [22]
Psychoactive drugs interact with particular target sites or receptors found in the nervous system to induce widespread changes in physiological or psychological functions. The specific interaction between drugs and their receptors is referred to as " drug action ", and the widespread changes in physiological or psychological function is ...
