Monograph
A03AA04 - Mebeverine |
Propably not porphyrinogenic |
PNP |
Rationale
Mebeverine is not listed as a CYP-inducer or inhibitor, and is not known to interfere with the CYP-metabolism of other drugs. There are no indications of porphyrinogenic effects connected with the pharmacodynamic properties of the drug.
Some preparations may include the laxative ispanhula, which also is classified PNP.
Chemical description
Mebeverine is the veratric acid ester of a substituted ethylamphetamine derivative.
Therapeutic characteristics
Mebeverine is an antispasmodic used in conditions such as irritable bowel syndrome. It is administered orally.
Metabolism and pharmacokinetics
Mebeverine is metabolised by hydrolysis to veratric acid and mebeverine alcohol. Mebeverine alcohol may go through further breakdown and conjugation before it is renally excreted.
Preclinical data
Moore and Hift claims porphyrinogenisity is shown in in vitro studies, but gives no references.
IPNet drug reports
Uneventful use reported in 2 patients with acute porphyria.

This list comprises raw data collected from different countries.
In some cases, a more comprehensive list of available drug packages is included.
Consequently, very similar terms may therefore appear multiple times.
Bold names are the searchable terms, while the gray names that follow are all mapped to the bolded term.
Note: The cleaning is done automatically by a proprietary algorithm, and it may produce errors.
We strive to improve it continuously.
