التداخل بين بوتالبيتال وباراسيتامول وإيزونيازيد

Acetaminophen A report of severe acetaminophen toxicity was reported in a patient receiving isoniazid.

It is believed that the toxicity may have resulted from a previously unrecognized interaction between isoniazid and acetaminophen and a molecular basis for this interaction has been proposed.

Studies have demonstrated that pretreatment with isoniazid potentiates acetaminophen hepatotoxicity in rats 1,2 .

Furthermore it has been proposed that isoniazid resulted in induction of P-450IIE1 in the patient's liver which, in turn, resulted in a greater proportion of the ingested acetaminophen being converted to the toxic metabolites.

Drug Interactions The CNS effects of butalbital may be enhanced by monoamine oxidase (MAO) inhibitors.
