Medical therapy or surgical therapy is performed after conservative therapy such as moisture restriction or diuretic drug administration is performed as a treatment for patent ductus arteriosa in premature infants, but before surgical therapy, medical therapy Pharmacological ligation therapy with prostaglandin (PG) synthesis inhibitor has been performed as a drug. In Japan, only the intravenous formulation of indomethacin sodium (indacin) was the only PG inhibitor with PDA indication. Although this indomethacin preparation has high effectiveness, side effects such as anuria, oliguria and renal dysfunction have been a problem to be solved.
Ibuprofen L-lysine preparation is the second drug as a PG synthesis inhibitor, and it has already been clinically used for PDA in Europe and the United States. In addition, ibuprofen preparations are reported to be more safe than indomethacin preparations.

The main one is urine volume reduction (including oliguria) (40.0%), renal dysfunction (25.0%), increase in blood creatine (20.0%), increase in blood urea (15.0%), the serious one Acute kidney injury, anuria, pulmonary hypertension, necrotizing enterocolitis, digestive tract perforation, ileus, thrombocytopenia, bleeding, gastrointestinal bleeding, pulmonary hemorrhage, intracranial hemorrhage have been reported.
Since ibuprofen L-lysine preparation is extremely limited in domestic clinical cases, it is necessary to conduct a usage record survey for all cases until data on a certain number of cases are accumulated after manufacturing and sales In addition to grasping the background information of patients using this drug, we will collect data on the safety and efficacy of this drug at an early stage and take necessary measures to properly use this drug.
