Tivorbex (indomethacin); Iroko Pharmaceuticals; For the treatment of acute pain, Approved February of 2014
PHILADELPHIA—Iroko Pharmaceuticals, LLC, a global specialty pharmaceutical company dedicated to advancing the science of analgesia, today announced that the U.S. Food and Drug Administration (FDA) has approved TIVORBEX™ (indomethacin) capsules, a nonsteroidal anti-inflammatory drug (NSAID), at 20 mg and 40 mg doses for the treatment of mild to moderate acute pain in adults1.
“TIVORBEX is the second NSAID to be approved from Iroko’s lower dose NSAID pipeline that uses proprietary SoluMatrix Fine Particle Technology™.”
TIVORBEX was approved at dosage strengths that are 20 percent lower than the 25 mg and 50 mg indomethacin products currently on the market2. FDA approval of TIVORBEX was supported by data from two Phase 3 multi-center, placebo-controlled trials that demonstrated significant improvement in pain relief in patients with post-surgical acute pain receiving TIVORBEX compared with patients receiving placebo3.
“The FDA approval of TIVORBEX is another significant milestone for Iroko as it validates our strategic approach towards developing a suite of NSAID products that offer pain management at lower doses,” said John Vavricka, President and CEO of Iroko Pharmaceuticals. “TIVORBEX is the second NSAID to be approved from Iroko’s lower dose NSAID pipeline that uses proprietary SoluMatrix Fine Particle Technology™.” read at
Indometacin (INN) or indomethacin (USAN and former BAN) is a non-steroidal anti-inflammatory drug (NSAID) commonly used as a prescriptionmedication to reduce fever, pain, stiffness, and swelling. It works by inhibiting the production of prostaglandins, molecules known to cause these symptoms. It is marketed under more than seventy different trade names.
Indomethacin was discovered in 1963 and it was first approved for use in the U.S. by the Food and Drug Administration in 1965. Its mechanism of action, along with several other NSAIDs that inhibit COX, was described in 1971.
