several days after stopping chemotherapy

leading to deep coma and death

Sympathomimetic

cause an abrupt increase in blood pressure, resulting in a

potentially fatal hypertensive crisis

in blood pressure, convulsions and coma may occur.Uneventual

concurrent use with MAOI inhibitors have been reported

Renal.heaptic function impairment- undue toxicity may occur if usedc in aptients with known impairment of reanl or hepatic function. Consider hospitilization for the initial treatment course.

Carcinogenesis/ Mutagenesis/fertility impairment- there is sufficient evidence for human carconogenicity of procarbazine Hcl. when it is given in intenssive regimes which include other antineoplastic agents., but there is inadequate evidence of carcinogenicity in humans given procarbazine Hcl alone.

Pharmacology/ Pharmacokinetics:

Pharmacology: Procarbazine may inhibit protein, ribonuleic acid (RNA) and deoxyribonucleic acid (DNA) synthesis

Pharmacokinetics: Procarbamazine is rapidly and completely absorbed from the GI tract and quickly equilbrates between plasma and cerbrospinal (CSF). Peak CSF levels occur in 30 to 90minutes.

Interaction with Food:

Drug/food interaction: Ingestion of foods with high tyramine content may cause an abrupt increase in blood pressure, resulting in a potentially fatal hypertensive crisis.

Pregnancy and lactation:

Pregnancy- Advice woman of child bearinng potential to avoid pregnancy. If this drug is used during pregnancy, inform patient of the potential hazards to the fetus.
