By What are examples of sympathomimetic drugs?
Sympathomimetic drugs—such as cocaine, amphetamines, phencyclidine hydrochloride (PCP), and lysergic acid diethylamide (LSD)—can precipitate a hypertensive emergency.
What are sympathomimetic drugs used for?
Sympathomimetic drugs form a classification of medication used to manage and treat cardiovascular pathology, hypersensitivity, COPD, and glaucoma.
How is sympathomimetic syndrome treated?
For sympathomimetic agents ingested orally, one may consider activated charcoal as long as the patient is alert. Hypertension unresponsive to the benzodiazepines should be managed with a shorting antihypertensive like labetalol or nitroprusside. The main medication for symptomatic treatment is a benzodiazepine.
What are the signs and symptoms of sympathomimetic toxicity?
The classic signs and symptoms (toxidrome) often seen with the sym- pathomimetic drugs include hyperactivity, mydriasis (dilated pupils), hypertension, tachycardia, and hyperthermia; some of these drugs also precipitate psychoses, hallucinations and seizures.
What drugs boost adrenaline?
Vasopressors
- ephedrine.
- epinephrine.
- dopamine.
- phenylephrine.
- pseudoephedrine.
- oxymetazoline.
What is the difference between sympathomimetic and Sympatholytic drugs?
A drug that enhances adrenergic function is known as a sympathomimetic drug, whereas a drug that interrupts adrenergic function is a sympatholytic drug.
Are Sympathomimetics toxic?
Sympathomimetic toxicity is frequently associated with significant agitation, thus necessitating the use of physical restraints and chemical sedation. However, physically restrained patients with sympathomimetic-associated agitation or hyperthermia have an associated significant risk of sudden death.
What are the side effects of sympathomimetics?
Side Effects of Sympathomimetics
- Headache.
- Reflex bradycardia.
- Excitability.
- Restlessness.
What are the adverse effects associated with high doses of sympathomimetic drugs?
Direct sympathomimetics
- Hypertension. (due to peripheral. vasoconstriction. ) and reflex. bradycardia.
- Urinary retention.
- Ischemia. and. necrosis. , especially of the fingers or toes.
- Rebound congestion (with. nasal decongestants. used > 4–6 days)
- Piloerection.
Which drug is an agonist of adrenaline?
Adrenergic Agonists
| Drug | Drug Description |
|---|---|
| Epinephrine | A hormone and neurotransmitter used to treat allergic reactions, to restore cardiac rhythm, and to control mucosal congestion, glaucoma, and asthma. |
| Tizanidine | An alpha-2 adrenergic agonist used for the short-term treatment of muscle spasticity. |
Is used as adrenergic drugs?
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.
Which drug is properly classified as sympathomimetic?
Sympathomimetics include substances such as epinephrine and norepinephrine, as well as synthetic drugs such as phenylephrine.
