How do drugs act on the central nervous system?

How do drugs act on the central nervous system?

Drug action Like neurotransmitters, drugs can speed up (CNS stimulants) or slow down (CNS depressants) the transfer of electro-chemical messages between neurons in the brain. Messages between neurons can also be distorted when hallucinogenic drugs are taken.

What are examples of CNS drugs?

What are prescription CNS depressants?

  • diazepam (Valium®)
  • clonazepam (Klonopin®)
  • alprazolam (Xanax®)
  • triazolam (Halcion®)
  • estazolam (Prosom®)

What is the CNS and PNS responsible for?

The CNS is made up of the brain and the spinal cord components. The PNS is all the nerves that branch out from the CNS components and extend to other parts of the body – to the sense organs, muscles, and glands. The PNS connects the CNS to the rest of the body.

How do drugs affect the peripheral nervous system?

Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons.

What are the drugs acting on the cardiovascular system?

Types of Cardiovascular agents

  • agents for hypertensive emergencies.
  • agents for pulmonary hypertension.
  • aldosterone receptor antagonists.
  • Angiotensin Converting Enzyme Inhibitors.
  • angiotensin receptor blockers.
  • angiotensin receptor blockers and neprilysin inhibitors.
  • antiadrenergic agents, centrally acting.

What drugs affect the CNS?

Drugs of abuse affecting the CNS include cocaine, heroin, alcohol, amphetamines, toluene, and cannabis. Prescribed medications or medical therapies that can affect the CNS include immunosuppressants, antiepileptics, nitrous oxide, and total parenteral nutrition.

What drugs act on the nervous system?

Stimulants are drugs that exert their action through excitation of the central nervous system. Psychic stimulants include caffeine, cocaine, and various amphetamines. These drugs are used to enhance mental alertness and reduce drowsiness and fatigue.

What controls the peripheral nervous system?

The somatic system is the part of the peripheral nervous system responsible for carrying sensory and motor information to and from the central nervous system. Motor neurons: Also called efferent neurons, motor neurons carry information from the brain and spinal cord to muscle fibers throughout the body.

How do the central nervous system and peripheral system work together to control the body?

The peripheral nervous system (PNS) is one of the two major components of the body’s nervous system. In conjunction with the central nervous system (CNS), the PNS coordinates action and responses by sending signals from one part of the body to another.

What drug speeds up the central nervous system?

Stimulants. Tend to speed up the activity of a person’s central nervous system (CNS) including the brain.

Which drug class exerts pharmacological action specifically on the central nervous system CNS?

Stimulants are drugs that exert their action through excitation of the central nervous system.
