N01BB04 - Prilocaine |
Not porphyrinogenic |
NP |
Rationale
Used uneventfully in 105 patients with latent or active acute porphyria. By clinical criteria the local anaesthetic prilocaine is not porphyrinogenic.
Chemical description
Prilocaine hydrochloride is a local anaesthetic of the amide type.
Therapeutic characteristics
Local anaesthetic.
Hepatic exposure
Volume required to reach uM concentrations when injected intravenously: approximately 2 ml (of prilocaine 30 mg/ml).
Metabolism and pharmakokinetics
Prilocaine hydrochloride is metabolized principally in the liver. Some metabolism of prilocaine may also occur in the kidneys. Prilocaine is excreted in urine as various metabolites and less than 1% as unchanged drug. Not been found to be an inducer or irreversible inhibitor of drug metabolizing cytochrome P450 species (Rendic, 2002).
Personal communication
Thunell, S., study to be published: 105 patients exposed without porphyric adverse reaction reported. Andersson: Reports to have frequently used it in infiltrations without illeffects.
IPNet drug reports
Uneventful use reported in 6 patients with acute porphyria.
