Not porphyrinogenic |
NP |
Rationale
Epinephrine (adrenaline) is an endogenous catecholamine with non-CYP dependent metabolism. There are no data pointing to CYP-interaction.
Chemical description
Endogenous catecholamine.
Therapeutic characteristics
Epinephrine (adrenaline) is a catecholamine used in asthma bronchiale, cardiac arrest, hypersensitivity reactions. Parenterally administered in 0.3-1 mg dose.
Metabolism and pharmacokinetics
Epinephrine (adrenalin) is an endogenous compound. It is very rapidly inactivated by processes which include uptake into adrenergic neurones, diffusion, and enzymatic degradation in the liver and body tissues. Metabolism involves monoamine oxidase (MAO) and catechol-O-methyl transferase (COMT). As a result of enzymatic degradation in the gut and first-pass metabolism in the liver, adrenaline is almost totally inactive when given orally.
IPNet drug reports
Uneventful use reported in 5 patients with acute porphyria, in combination with local anaesthetics.
