What are adrenergic drugs in pharmacology?

Adrenergic drugs are medications that stimulate certain nerves in your body. They do this either by mimicking the action of the chemical messengers epinephrine and norepinephrine or by stimulating their release….Vasopressors

  • ephedrine.
  • epinephrine.
  • dopamine.
  • phenylephrine.
  • pseudoephedrine.
  • oxymetazoline.

What is adrenergic drug example?

Examples of adrenergic drugs which selectively bind to alpha-1 receptors are phenylephrine, oxymetazoline. Selective alpha-2 receptor drugs include methyldopa and clonidine. The key beta-1 selective drug is dobutamine. Lastly, beta-2 selective drugs are bronchodilators, such as albuterol and salmeterol.

What are adrenergic and Antiadrenergic drugs?

Centrally acting antiadrenergic agents inhibit the stimulation of the central nervous system alpha-adrenergic receptors and decrease sympathetic stimulation to the blood vessels and the heart.

What are the classification of adrenergic blocking drugs?

β-adrenergic receptor blockers can be classified as being nonselective, selective, and β blockers with additional properties such as the ability to generate nitric oxide, inhibit free radial formation, and inhibit hypertrophic growth.

What are adrenergic neurotransmitters?

An adrenergic nerve fibre is a neuron for which the neurotransmitter is either adrenaline (epinephrine), noradrenaline or dopamine. These neurotransmitters are released at a location known as the synapse, which is a junction point between the axon of one nerve cell and the dendrite of another.

What is another name for an adrenergic drug?

Adrenergic (Sympathomimetic) Drugs Naturally occurring molecules that bind to these receptors include epinephrine (11.1), which binds to α1,α2, and β1 receptors, norepinephrine (11.2), which binds to α1, α2, and β1 receptors, and dopamine (11.3), which binds to dopamine receptors as well as to α1 and β1 receptors.

What are adrenergic drugs side effects?

Some of the side effects of adrenergic agonist drugs include:

  • Headache.
  • Tremor.
  • Irritation/burning in the eye.
  • Blurred vision.
  • Hypertension.
  • Tachycardia (irregular heartbeat)
  • Palpitation.
  • Dry mouth.

What is the function of adrenergic receptors?

Adrenergic receptors are cell surface glycoproteins that recognize and selectively bind the catecholamines, norepinephrine and epinephrine, which are released from sympathetic nerve endings and the adrenal medulla.

What are the 5 adrenergic receptors?

there are five types of adrenergic receptors (receptors binding epinephrine): α1, α2, β1, β2, and β3. These adrenoceptors are found in different combinations in various cells throughout the body.
