Pivmecillinam (INN), or amdinocillin pivoxil (USAN), sold under the brand name Selexid and Pivya among others, is an orally active prodrug of mecillinam, an extended-spectrum penicillin antibiotic. Pivmecillinam is the pivaloyloxymethyl ester of mecillinam. The most common side effects include nausea and diarrhea. In the US, pivmecillinam is indicated for the treatment of female adults with uncomplicated urinary tract infections caused by susceptible isolates of Escherichia coli, Proteus mirabilis, and Staphylococcus saprophyticus. Pivmecillinam is primarily active against Gram-negative bacteria, and is used primarily in the treatment of lower urinary tract infections. In the Nordic countries, it has been widely used in that indication since the 1970s. The adverse effect profile of pivmecillinam is similar to that of other penicillins. The most common side effects of mecillinam use are rash and gastrointestinal upset, including nausea and vomiting. Prodrugs that release pivalate anions when broken down by the body — such as pivmecillinam, pivampicillin and cefditoren pivoxil — have long been known to deplete levels of carnitine. This is not due to the drug itself, but to the pivalate anion, which is mostly removed from the body by forming a conjugate with carnitine.
