Losmapimod (GW856553, GSK-AHAB) is a selective, potent, and orally active p38 MAPK (p38α and p38β isoforms) inhibitor that acts by competing for the kinase ATP binding site. GlaxoSmithKline (GSK) is developing oral losmapimod for the treatment of acute coronary syndromes (phase III), chronic obstructive pulmonary disease (phase II) and primary focal segmental glomerulosclerosis (phase II). Oral losmapimod was in phase II development for the treatment of rheumatoid arthritis and major depressive disorder; however, it appears that development for these indications has been discontinued. No further development was reported for atherosclerosis, dyslipidaemia and neuropathic pain.

Sample Use Guides
Oral losmapimod 2.5 - 20 mg twice daily.
A single IV infusion of losmapimod (3 mg) may potentially serve as an initial loading dose in acute coronary syndrome as rapid exposure is achieved.
