What are sympathomimetic classify them with suitable examples?
Sympathomimetics can be divided based on the type of receptors, for which they have a higher affinity, i.e. their spectrum of action. For example, epinephrine is both an α and β agonist, whereas phenylephrine is predominantly an α1 agonist.
What are sympathomimetics also called?
Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines) are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system.
Is sympathomimetic a drug class?
Sympathomimetic Drugs and Adrenergic Receptor Antagonists They are classified as directly acting (act directly on α or β receptors), indirectly acting (act by providing more norepinephrine to act on α or β receptors), or mixed acting (act by both mechanisms).
What is sympathomimetic activity?
Definition. The property of a drug that produces partial agonist effect at the receptor similar to the cholinergic stimulation of the sympathetic nervous system. Supplement. Intrinsic sympathomimetic activity or ISA is often used to describe the property of certain beta-blockers.
What are Sympathoplegic drugs?
A sympatholytic (or sympathoplegic) drug is a medication that opposes the downstream effects of postganglionic nerve firing in effector organs innervated by the sympathetic nervous system (SNS). They are indicated for various functions; for example, they may be used as antihypertensives.
What’s adrenergic mean?
1 : liberating, activated by, or involving adrenaline or a substance like adrenaline an adrenergic nerve. 2 : resembling adrenaline especially in physiological action adrenergic drugs.
Which drugs have intrinsic sympathomimetic activity?
Beta-Blockers, Intrinsic Sympathomimetic Agents such as acebutolol and pindolol possess intrinsic sympathomimetic activity (ISA). These agents can be used alone or in combination with other antihypertensive agents, particularly with a thiazide-type diuretic.
What does action do sympathomimetic drugs have in?
Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors, blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines .

What are sympathomimetic amines?
sympathomimetic amine. an amine that mimics the actions of the sympathetic nervous system. The group includes the catecholamines and drugs that mimic their actions.
