Orfadin and Prochlorperazine Edisylate

• Generic Name: nitisinone
• Dosage Forms: capsule
• Other Brand Names: Orfadin, Nityr

Orfadin works by preventing the body from breaking down an amino acid called tyrosine and by keeping other toxic substances from building up and causing harm to your liver or kidneys.

Orfadin is used to treat a rare genetic condition called hereditary tyrosinemia type 1 (HT-1). HT-1 is a metabolic disorder that occurs when the body does not produce enough of an enzyme that breaks down proteins from certain foods. This condition occurs most often in young babies.

Orfadin may also be used for purposes not listed in this medication guide.

• Generic Name: prochlorperazine
• Dosage Forms: n.a.
• Other Brand Names: Compazine, Compro

Symptomatic management of psychotic disorders (i.e., schizophrenia).

Short-term management of nonpsychotic anxiety.

Efficacy established in patients with generalized anxiety disorder; not established whether prochlorperazine is useful for the management of other nonpsychotic conditions in which anxiety or manifestations that mimic anxiety are evident (e.g., physical illness, organic mental conditions, agitated depression, character pathologies).

Because of the risks of toxicity, use only as an alternative to other less toxic anxiolytic agents (e.g., benzodiazepines) in most patients.

Management of severe nausea and vomiting of various etiologies (e.g., postoperative, acute migraine, toxins, radiation, or cytotoxic drugs).

Not effective in preventing vertigo or motion sickness, or for the management of emesis caused by the action of drugs on the nodose ganglion or locally on the GI tract.

Use not recommended for the prevention and treatment of nausea and vomiting associated with pregnancy except in cases of severe nausea and vomiting so serious and intractable that pharmacologic intervention is required and the potential benefits justify the possible risks to the fetus. (See Fetal/Neonatal Morbidity under Cautions.)

Has not been shown to be effective for the management of behavioral complications in patients with mental retardation.
