tace and Panhematin Interactions

Interactions between tace(chlorotrianisene) and Panhematin (hemin)

chlorotrianisene and hemin (Major Drug-Drug)

GENERALLY AVOID: Coadministration with drugs that are capable of increasing the activity of delta-aminolevulinic acid synthetase (e.g., estrogens, barbiturates, steroid metabolites, rifampin) may negate the pharmacologic effect of hemin. In the treatment of porphyria, hemin is thought to limit the rate of porphyrin/heme biosynthesis by inhibiting delta-aminolevulinic acid synthetase, thus any induction of this enzyme would be expected to counteract the therapeutic effect of hemin.

MANAGEMENT: Drugs capable of increasing the activity of delta-aminolevulinic acid synthetase should be avoided during hemin therapy.
