Monograph
L01XA02 - Carboplatin |
Not porphyrinogenic |
NP |
Rationale
Non-CYP metabolism. However, side effects such as nausea, anorexia and vomiting may be potentially porphyrinogenic through reduction in caloric intake.
Chemical description
Carboplatin is a platinum coordination compound composed of a platinum atom surrounded in a plane by 2 ammonia groups and 2 other ligands in the cis position(diaminocyclobutane dicarboxy platinium).
Therapeutic characteristics
Carboplatin is a platinum-containing antineoplastic agent used in the treatment of ovarian tumours, lung cancer and certain head and neck cancers.
It is administered as an intravenous infusion. Common adverse reactions of carboplatin that can be confused with an acute porphyric attack are vomiting, nausea, GI pain, and constipation. Side effects such as nausea, anorexia and vomiting may be potentially porphyrinogenic through reduction in caloric intake.
Metabolism and pharmacokinetics
Carboplatin is mainly excreted unchanged by the kidneys. Partly non-enzymatically degraded. No reports of drug interactions pointing to CYP-metabolism.
Not listed by Rendic (2002) as CYP-inducer or inhibitor. Carboplatin did not exert a significant effect on the PXR-mediated induction of CYP3A4 (Harmsen, 2009). Carboplatin was without inhibitory effect on CYP3A4 (Baumhakel, 2001).
Published experience
Used uneventfully in AIP woman in the treatment of squamous cell carcinoma of the uterus (Thiery-Vuillemin, 2008).
IPNet drug reports
Uneventful use reported in 1 patient 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.
