Nine previously untreated hypertensive patients (WHO Stage I and II) were given hydrochlorothiazide (hct) 12.5, 25, 50 and 75 mg for two weeks after an initial four week period of placebo treatment. Blood pressure recordings were made casually and after 30 min rest in lying, sitting and standing positions. Plasma concentrations of the drug were measured by(More)
14C-hydrochlorothiazide (hct) was administered orally (n=4) and iv (n = 2 to healthy subjects. The gastrointestinal absorption ranged between 60% and 80%, most of it took place in the duodenum and the upper jejunum. The radioactivity was eliminated mainly in the urine, while no sigificant biliary excretion was observed. Chromatographic analysis of the(More)
Hydrochlorothiazide 775mg was administered orally to 5 patients who had undergone intestinal shunt operations for obesity 1.5 to 6 years previously. Postoperative weight loss averaged 53.4kg. The concentrations of hydrochlorothiazide in plasma and urine were determined with gas/liquid chromatography. The mean area under the plasma concentration time curve(More)
1. Hydrochlorothiazide (HCT, 50-75 mg) was administered orally to seven patients with cardiac failure. 2. Plasma levels and urinary concentration of HCT were determined by GLC. 3. The gastrointestinal uptake of the diuretic in three patients was reduced to approximately half that seen in healthy controls. 4. Plasma halflife of HCT was correlated with(More)
After four weeks on placebo treatment, 8 hypertensive patients (WHO stage I) were treated for 2 weeks with bendroflumethiazide (bft) 2.5 mg and KCl 1.5 g daily. Subsequently they received bft 5 mg and KCl 1.5 g daily for a further fortnight. At the end of each period of treatment blood pressure was recorded and blood samples and urine were collected for(More)
Bendroflumethiazide (bft), 10 mg, was administered orally to 9 healthy volunteers. The concentrations of the diuretic in plasma and urine were determined by gas-liquid chromatography (GLC). Peak plasma levels (86 +/- 18 ng/ml) of bft were reached at 2 +/- 0.4 hr. The concentration declined with a mean t1/2 of 3.0 hr. The apparent volume of distribution(More)
Hydrochlorothiazide (hct) 75 mg was administered orally to eight healthy volunteers without (Study I) or together with a standaridized meal (Study II), and plasma and urine concentrations of hct were analyzed by GLC. The plasma levels of hct were higher initially when the tablets were taken on an empty stomach, but after 5 h they were higher in Study II.(More)
