IBUPROFEN LYSINE · XGEN PHARMS

Cardiovascular Approved 2006-04-13

Ibuprofen Lysine is indicated to close a clinically significant patent ductus arteriosus (PDA) in premature infants weighing between 500 and 1500 g who are 32 weeks gestational age or less. It is intended for use when usual medical management (e.g., fluid restriction, diuretics, and respiratory support) has proven ineffective. Because long-term consequences beyond 8 weeks post-treatment have not been evaluated, treatment should be reserved for infants with clear evidence of a clinically significant PDA.

How IBUPROFEN LYSINE Works

The specific mechanism by which ibuprofen induces closure of a patent ductus arteriosus (PDA) in neonates is not fully known. In adults, ibuprofen is an inhibitor of prostaglandin synthesis. This inhibition of prostaglandins is the mechanism generally associated with the drug’s therapeutic effect in closing the ductus.
