When the arm circumference was larger than 32 cm,
a larger cuff was used. If, at the screening visit, previously untreated patients had Apitolisib cost a blood pressure of 160–199 mmHg systolic or 100–119 mmHg diastolic, and if patients previously treated with antihypertensive monotherapy had a blood pressure of 140–179 mmHg systolic or 90–109 mmHg diastolic and had discontinued their previous antihypertensive monotherapy, they could enter the wash-out phase for determination of eligibility. After the wash-out run-in phase, eligible patients entered the 12-week study treatment period and started taking irbesartan/hydrochlorothiazide 150 mg/12.5 mg once daily. A tablet of irbesartan 150 mg and an additional tablet of irbesartan/hydrochlorothiazide 150 mg/12.5 mg could be added at 4 and 8 weeks of follow-up, respectively, for systolic/diastolic blood pressure to reach the target level of <140/90 mmHg, or <130/80 mmHg in patients with diabetes mellitus. The study medication could also be stopped in the presence of symptomatic hypotension or any other serious adverse events related to the study medication. The purpose of the clinic visit at 2 weeks of follow-up was to assure MK-1775 concentration the safety of and patient compliance with antihypertensive therapy. It was decided that the study medication should not change at 2 weeks of follow-up, unless such a change was necessary. Patients were instructed to take the study medication between 08:00 and 10:00 h
every morning except on the day of the clinic visit, when the medication was administered after blood pressure had been measured. Other antihypertensive agents or drugs with a potential blood pressure-lowering or blood pressure-increasing action were not to be used during the 12-week study treatment period. The study medication was supplied free of charge for the whole study
period by Sanofi China (Shanghai, China). 2.2 Study Population Florfenicol Eligible patients were men and women aged 18–75 years, with a blood pressure of 160–199 mmHg systolic or 100–119 mmHg diastolic at the clinic visit at the end of the 1-week wash-out phase. The exclusion criteria for the study were as follows: blood pressure ≥200 mmHg systolic or ≥120 mmHg diastolic; secondary hypertension; women who were pregnant, lactating, or of childbearing potential without proper contraception; cardiac diseases including cardiomyopathy, valvular heart disease, heart failure, or documented left ventricular ejection fraction reduction (<45 %); severe arrhythmias such as ventricular or supraventricular arrhythmia, pre-excitation syndrome, second-degree or third-degree atrioventricular block and sick sinus syndrome; and other significant, uncontrolled, or life-threatening conditions or diseases. We also excluded patients with a serum concentration of alanine or aspartate transaminase ≥2 times the upper normal limits; a serum creatinine concentration ≥176.8 μmol/l; creatinine clearance or an estimated glomerular filtration rate <30 ml/min per 1.
