The corresponding additional reduction in supine diastolic blood pressure was 7 mmHg. Special populations, elderly ( 65 sildenafil years). CYP3A4 inducers seemed to have a substantial impact on the pharmacokinetics of sildenafil in pulmonary arterial hypertension patients, which was confirmed in the in-vivo interaction study with CYP3A4 inducer -administration of bosentan (a moderate inducer of CYP3A4, CYP2C9.
