The effect of drotaverine hydrochloride in acute colicky pain caused by renal and ureteric stones.

OBJECTIVE: To assess the spasmolytic effect of drotaverine hydrochloride in colicky pain caused by renal and ureteric stones. PATIENTS AND METHODS: In a placebo-controlled, multicentre, multinational, randomized, double-blind study changes in the intensity of pain were recorded using a visual analogue scale (VAS), a four-grade (five points) pain intensity (PI) scale and a pain-relief scale. The primary endpoint was the evaluation of the antispasmodic effect of drotaverine during a 3-h study period, to confirm that drotaverine abolished or significantly decreased the intensity of pain in renal colic. The painkilling effect was defined as a decrease by at least half in the PI scale, and/or a >or= 40% decrease in the VAS 40 min after either the first or the second injection of 80 mg drotaverine or placebo (if necessary the dose could be repeated once). In all, 140 patients were enrolled but 38 withdrew, leaving 102 patients for analysis (48 drotaverine, 54 placebo; mean age 42.5 years, sd 11.25, and 41.7, sd 10.79). RESULTS: Drotaverine was effective in 79% of patients and placebo in only 46% (P < 0.001). There were no serious adverse effects. There were 20 minor side-effects in the drotaverine and four in the placebo group; none of the patients required treatment. The most frequent side-effects were a transitory decrease in blood pressure, vertigo, nausea or vomiting. CONCLUSION: Intravenous drotaverine provides effective pain relief in more than two-thirds of patients with renal colic, with no serious side-effects.

Effects of losartan and candesartan monotherapy and losartan/hydrochlorothiazide combination therapy in patients with mild to moderate hypertension. Losartan Trial Investigators.

OBJECTIVE: The goal of this multicenter, double-blind, randomized, parallel-group study was to compare the effects of losartan potassium (hereafter referred to as losartan), candesartan cilexitil (hereafter referred to as candesartan), and losartan/hydrochlorothiazide (HCTZ) in patients with mild to moderate hypertension (sitting diastolic blood pressure [SiDBP] 95-115 mm Hg). METHODS: A total of 1161 patients were randomized in a 2:2:1 ratio to 12 weeks of treatment with losartan 50 mg QD, possibly titrated to 100 mg QD (n = 461); candesartan 8 mg QD, possibly titrated to 16 mg QD (n = 468); or losartan 50 mg QD, possibly titrated to losartan 50 mg plus HCTZ 12.5 mg QD (n = 232). At 6 weeks, the regimens of patients not reaching a goal SiDBP <90 mm Hg were titrated as described, whereas patients achieving this goal continued with low-dose monotherapy. The single primary end point at 12 weeks tested the equivalence of the 2 monotherapy regimens, predefined as a maximum between-treatment difference in the mean change from baseline trough SiDBP of 2.5 mm Hg. RESULTS: At 12 weeks, changes in SiDBP/sitting systolic blood pressure (SiSBP) of -12.4/-14.4 mm Hg with losartan 50 mg/100 mg and -13.1/-15.8 mm Hg with candesartan 8 mg/16 mg demonstrated equivalence between the 2 monotherapy regimens (95% CI for difference in SiDBP, -1.6 to 0.2). At 12 weeks, the losartan 50 mg/50 mg plus HCTZ 12.5 mg regimen had reduced SiDBP/SiSBP significantly more (-14.3/-18.0 mm Hg) than either the candesartan 8 mg/16 mg (SiDBP, P = 0.045; SiSBP, P = 0.017) or losartan 50 mg/100 mg regimen (SiDBP and SiSBP, P = 0.001). During the last 6 weeks, patients whose regimen had been titrated to losartan 50 mg plus HCTZ 12.5 mg (n = 114) showed a greater reduction in SiDBP/SiSBP (-14.5/ -18.7 mm Hg) than did those whose regimen had been titrated to either losartan 100 mg (-10.5/-12.3 mm Hg; n = 211) or candesartan 16 mg (-11.5/-13.2 mm Hg; n = 206), representing a clinically meaningful > or = 2.5-mm Hg) difference. All 3 treatments were well tolerated, with few patients experiencing drug-related adverse events (6.9% losartan 50 mg/100 mg, 7.5% candesartan 8 mg/16 mg, 3.0% losartan 50 mg/ 50 mg plus HCTZ 12.5 mg). Candesartan 8 mg/16 mg increased serum uric acid levels (0.13 mg/dL; 95% CI, 0.04 to 0.23), whereas losartan 50 mg/100 mg decreased them (-0.14 mg/dL; 95% CI, -0.24 to -0.04), and losartan 50 mg/50 mg plus HCTZ 12.5 mg left them unchanged (0.06 mg/dL; 95% CI, -0.07 to 0.20). CONCLUSIONS: Losartan 50 mg/100 mg and candesartan 8 mg/16 mg were comparable treatments in terms of blood pressure reduction. After titration, losartan 50 mg plus HCTZ 12.5 mg was superior to either candesartan 16 mg or losartan 100 mg in reducing hypertension. Losartan, but not candesartan, lowered serum uric acid levels and attenuated the expected increase in uric acid levels with HCTZ 12.5 mg.
