This is a list of adrenergic drugs. These are pharmaceutical drugs , naturally occurring compounds and other chemicals that influence the function of the neurotransmitter epinephrine (adrenaline). Receptor ligands
An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors.The five main categories of adrenergic receptors are: α 1, α 2, β 1, β 2, and β 3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively.
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.
Beta 2-adrenergic agonists, also known as adrenergic β 2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists , they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages , vasodilation in muscle and liver ...
The specific interaction between drugs and their receptors is referred to as "drug action", and the widespread changes in physiological or psychological function is referred to as "drug effect". [2] These drugs may originate from natural sources such as plants and animals, or from artificial sources such as chemical synthesis in the laboratory.
The most common of these binding sites, benzodiazepine, allows for both agonist and antagonist effects on the receptor. A common drug, diazepam, acts as an allosteric enhancer at this binding site. [5] Another receptor for GABA, known as GABA B, can be enhanced by a molecule called baclofen. This molecule acts as an agonist, therefore ...
Bethanechol is a muscarinic agonist.It is included in the therapy for underactive bladder with poor contraction of detrusor muscle. [2] Since contraction of detrusor muscle in the bladder is controlled by the parasympathetic nervous system, Bethanechol can bind to muscarinic receptors to stimulate activation of the parasympathetic nervous system and restore contraction of detrusor muscle.
Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS) and are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling.
