Which effect occurs in calcium channel blocker toxicity? Urinary alkalinization does not affect the elimination of nifedipine (Procardia), digoxin (Lanoxin), or paroxetine (Paxil). Urinary alkalinization can increase the renal elimination of phenobarbital (Luminal) and salicylates by changing them to a less-absorbable ionized form. Urinary alkalinization increases the renal elimination of which substance? Procainamide (Pronestyl) and other class IA antidysrhythmics, such as quinidine (Quinidex), are contraindicated because of the risk of QRS widening.

Digoxin (Lanoxin) is not used to treat ventricular dysrhythmias. For a patient with tricyclic antidepressant toxicity, you should expect to treat ventricular dysrhythmias with which cardiac medication?Įxpect to use amiodarone (Cordarone) to treat ventricular dysrhythmias caused by tricyclic antidepressant toxicity. Other effects of tricyclic antidepressant toxicity include tachycardia due to anticholinergic and quinidine-like effects acidosis and hyperthermia.

Which disorder is a major cause of death in tricyclic antidepressant toxicity?Ī major cause of death from tricyclic antidepressant toxicity is refractory hypotension due to decreased cardiac contractility and peripheral vasodilation. With a toxic ingestion, the tricyclic antidepressant amitriptyline (Elavil) produces central nervous system depression. Methaqualone (Quaalude) leads to central nervous system depression and may cause hypertonicity, hyperreflexia, or clonus. An antihypertensive drug, clonidine (Catapres) is an alpha2 agonist that causes central nervous system depression. Which drug can cause a sense of omnipotence, excitement, hyperalertness, hyperactivity, or hypersexuality?Īmphetamine is a central nervous system stimulant that can cause a sense of omnipotence, excitement, hyperalertness, hyperactivity, or hypersexuality. Cyproheptadine is not used to treat overdoses of opiates, such as oxycodone (Ox圜ontin), or tricyclic antidepressants, such as doxepin (Sinequan) or amitriptyline (Elavil). Cyproheptadine (Periactin) may be used to treat an overdose of which drug?Ĭyproheptadine (Periactin) blocks serotonin syndrome caused by an overdose of a selective serotonin reuptake inhibitor, such as bupropion (Wellbutrin). Nystagmus occurs in patients with phencyclidine hydrochloride (PCP) toxicity. In a patient who overdosed on cocaine, which finding is expected?Ĭocaine is a central nervous system stimulant, so the signs and symptoms of overdose include tachycardia, hypertension, hyperthermia, insomnia, hallucinations and agitation.
