Imidapril is an angiotensin-converting enzyme inhibitor that is widely used in treating hypertension, although the responses vary among individuals. We investigated whether a single nucleotide polymorphism at position -816 of the carboxylesterase 1 (CES1) gene, which activates imidapril in the liver, is involved in the responsiveness to imidapril medication. A total of 105 Japanese hypertensives with systolic/diastolic blood pressures (SBP/DBP) of 140190 mmHg or higher were prescribed 5-10 mg/day of imidapril. At baseline, blood pressure levels were not different between patients with and those without the -816C allele (AA vs. AC+CC groups). After 8 weeks of treatment, we classified the responders and non-responders based on the decline in their blood pressures, and found that the responder rate was significantly higher in the AC+CC group than in the AA group (p=0.0331). Also, the reduction in SBP was significantly greater in the AC+CC group than in the AA group (24.7 +/- 11.8 vs. 17.6 +/- 16.8 mmHg, p=0.0184). Furthermore, an in vitro reporter assay revealed that the -816C construct had significantly higher promoter activity (p
