  2. Adrenergic agonist - Wikipedia

    en.wikipedia.org/wiki/Adrenergic_agonist

    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.

  3. List of adrenergic drugs - Wikipedia

    en.wikipedia.org/wiki/List_of_adrenergic_drugs

    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

  4. Beta2-adrenergic agonist - Wikipedia

    en.wikipedia.org/wiki/Beta2-adrenergic_agonist

    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 ...

  5. Adrenergic neuron blockers - Wikipedia

    en.wikipedia.org/wiki/Adrenergic_neuron_blockers

    Higher selectivity is associated with less off-target binding, which is binding between drug molecules and receptors other than target receptors. [6] Therefore, non-selective adrenergic blockers can cause various adverse effects as they can also exert actions on non-target receptors, such as non-selective alpha blockers and beta blockers.

    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 ...

  7. Agonist-antagonist - Wikipedia

    en.wikipedia.org/wiki/Agonist-antagonist

    Agonist vs. antagonist. In pharmacology the term agonist-antagonist or mixed agonist/antagonist is used to refer to a drug which under some conditions behaves as an agonist (a substance that fully activates the receptor that it binds to) while under other conditions, behaves as an antagonist (a substance that binds to a receptor but does not activate and can block the activity of other agonists).

  8. Parasympathomimetic drug - Wikipedia

    en.wikipedia.org/wiki/Parasympathomimetic_drug

    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.

  9. Dopamine agonist - Wikipedia

    en.wikipedia.org/wiki/Dopamine_agonist

    Pramipexole is a highly active non-ergot D 2-like receptor agonist with a higher binding affinity to D 3 receptors rather than D 2 or D 4 receptors. The mechanism of action of pramipexole is mostly unknown, it is thought to be involved in the activation of dopamine receptors in the area of the brain where the striatum and the substantia nigra ...
