What are the different drugs acting on ANS?
Drugs acting on Autonomic Nervous System, Sympathomimetic drugs (Adrenergic Agonist) Sympatholytic drugs (Adrenergic Antagonist) Alpha Blockers Beta Blockers B.
What is ANS in pharmacology?
The autonomic nervous system (ANS) is a complex set of neurons that mediate internal homeostasis without conscious intervention or voluntary control. • Thus respiration, circulation, digestion, body temperature, metabolism, sweating and the secretion of certain endocrine gland are regulated in part or entirely by ANS.
What are autonomic nervous system drugs?
Autonomic drugs are used clinically to either imitate or inhibit the normal functions of the sympathetic and parasympathetic nervous systems. A large number of additional drug classes also interact with these systems to produce a stunning number of possible side effects.
What are the drugs acting on sympathetic nervous system?
The main drugs that have been clearly shown to affect SNS function are beta-blockers, alpha-blockers, and centrally acting drugs. On the contrary, the effects of ACE inhibitors (ACE-Is), AT1 receptor blockers (ARBs), calcium channel blockers (CCBs), and diuretics on SNS function remain controversial.
What are sympathetic and parasympathetic drugs?
Autonomic drugs can either inhibit or enhance the functions of the parasympathetic and sympathetic nervous systems. This type of drug can be used to treat a wide range of diseases, such as glaucoma, asthma, urinary, gastrointestinal and cardiopulmonary disorders.
What is the difference between SNS and PNS?
The parasympathetic nervous system (PNS) controls homeostasis and the body at rest and is responsible for the body’s “rest and digest” function. The sympathetic nervous system (SNS) controls the body’s responses to a perceived threat and is responsible for the “fight or flight” response.
