What does a sympathomimetic drug do?

What does a sympathomimetic drug do?

Sympathomimetic drugs mimic or stimulate the adrenergic nervous system, and they can raise blood pressure to alarming heights, particularly in hypertensive patients.

What is an example of sympathomimetic drugs?

Direct stimulation of the α- and β-adrenergic receptors can produce sympathomimetic effects. Salbutamol is a widely used direct-acting β2-agonist. Other examples include phenylephrine, isoproterenol, and dobutamine.

How do mixed acting sympathomimetic drugs work?

Sympathomimetics are drugs that mimic the stimulation of the sympathetic nervous system. 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).

Which of the following are effects of sympathomimetic drugs?

Side Effects of Sympathomimetics

  • Headache.
  • Reflex bradycardia.
  • Excitability.
  • Restlessness.

Which is the best description of a sympathomimetic drug?

Are there any drugs similar to sympathetic activation?

Drugs that have effects similar to those of sympathetic activation are called sympathomimetic drugs. Which of the following would you not expect to observe in a person who has taken a sympathomimetic drug?

How are sympathomimetic drugs used in the treatment of ostium?

Decongestant medications. Sympathomimetic drugs that influence alpha-adrenergic receptors have been used as therapeutic agents for the decongestion of mucous membranes. Both systemic and topical decongestant medications have been used in reversing a nonpatent ostium.

How are sympathomimetic drugs similar to catecholamines?

These agents are able to directly activate adrenergic receptors or to indirectly activate them by increasing norepinephrine and epinephrine (mediators of the sympathoadrenal system) levels. Chemically these drugs are catecholamines (Figure 1) or are structurally similar to catecholamines. The parent structure is β -phenylethylamine.
