Also known as 3-Benzoylhydratropic acid, Capisten, Orudis, Orudis (tn), Oruvail, m-Benzoylhydratropic acid

A propionic acid derivate and nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic and antipyretic effects. Ketoprofen inhibits the activity of the enzymes cyclo-oxygenase I and II, resulting in a decreased formation of precursors of prostaglandins and thromboxanes. The resulting decrease in prostaglandin synthesis, by prostaglandin synthase, is responsible for the therapeutic effects of ibuprofen. Ketoprofen also causes a decrease in the formation of thromboxane A2 synthesis, by thromboxane synthase, thereby inhibiting platelet aggregation.

Can I take Ketoprofen while breastfeeding?

Although ketoprofen has low levels in breastmilk, one center reported that they had received reports of adverse renal and gastrointestinal side effects in breastfed infants whose mothers were taking ketoprofen. Other agents are preferred, especially while nursing a newborn or preterm infant.

Drug levels

Maternal Levels. Eighteen women were given ketoprofen 100 mg every 12 hours (average 2.69 mg/kg daily) intravenously for 2 to 3 days postpartum. One to 4 milk samples were collected between the 3rd and 4th dose of ketoprofen. Of the 61 samples collected, ketoprofen was undetectable (<20 mcg/L) in 17 of the samples. The authors assumed a milk concentration of 20 mcg/L for undetectable samples and calculated an average milk concentration of 57 mcg/L (range 20 to 177 mcg/L). A fully breastfed infant would receive an average dosage of 8.5 mcg/kg daily or 0.31% of the maternal weight-adjusted dosage.[1] Infant Levels. Relevant published information was not found as of the revision date.
