Daily administration of 900 mg dihydroxydibutylether (DHBE) produced a significant reduction of lithogenic index in patients with cholesterol gallstones. After treatment with placebo, in the same subjects the lithogenic index rises significantly. The activity of DHBE is not casual.
Oral administration of 900 mg daily of dihydroxydibutylether to patients with cholesterol stones in the gall-bladder, reduced the lithogenic index of the bile, whose mean value shifted from 1.64 to 1.03 (p less than 0.01) after 20 days of treatment. Reduction of lithogenic index must be ascribed exclusively to the reduced biliary concentration of cholesterol.

Administration of chenodeoxycholic acid (CDCA) to patients with primary hypertriglyceridemia caused the diminution of serum triglyceride concentrations of 54.31% and 46.04% at dosages of 500 mg/day and of 250 mg/day, respectively. Results after 1 month of treatment with 250 mg/day are not statistically different from those obtained with 500 mg/day. Administration of CDCA did not change the serum cholesterol, SGOT, SGPT, total bilirubin, gammaGT or alkaline phosphatase levels.
Administration of chenodeoxycholic acid (CDCA), 200 mg/day, for 5 days to patients with primary hypertriglyceridemia reduced by 34% the serum triglycerides concentration. Reduction after CDCA is statistically significant vs. the placebo. Even after a short time of CDCA administration, the pharmacological effect is clearly evident.
The clinical course of the first case of acute poisoning from melitracen, a tricyclic antidepressant, is described, whose symptomatology was characterized by the absence of cardiovascular changes (ECG, arterial pressure, cardiac frequency). Central anticholinergic effects of the drug, as excitement, hallucinations, space and time disorientation, regressed with the administration of diazepam.

Nebivolol has been adequately tested in clinical efficacy trials of patients with mild hypertension. Clinical efficacy trials or their meta-analyses did not accurately predict the outcome of subsequent large studies. The primary objective was to assess the efficacy/safety of nebivolol 5-10 mg daily in a nationwide study of patients with mild hypertension. Secondary objectives were (1) to compare efficacy/safety as monotherapy versus add-on therapy and (2) to assess the effect of nebivolol on ISH. This was an open-label, 6-week follow-up study of 6,356 patients with mild hypertension or ISH, as defined by the 1999 World Health Organization guidelines, recruited from 2,700 facilities. Previous monotherapies were continued except for beta-blockers. Results are reported as means+/-SDs. Intention-to-treat analysis is given. A total of 5,740 patients completed the study; of the withdrawals, 90% were lost for follow-up or were noncompliant, 38% were untreated before, 23% had beta-blockers. In the accumulated data, mean systolic and diastolic blood pressures fell by 24+/-14 and 13+/-9 mm Hg (both P<0.001). The differences between the blood pressure-reducing effects of nebivolol monotherapy and add-on therapy were not statistically significant: 28+/-16 and 22+/-14 mm Hg for systolic and 15+/-11 and 11+/-8 mm Hg for diastolic blood pressures. Adverse events were limited to 0.5% of the patients, no serious adverse events were observed. In the ISH patients, diastolic blood pressure fell by 4+/-6 mm Hg compared with 15+/-10 mm Hg in the no-ISH patients (P<0.01). Efficacy-safety effects of nebivolol in patients with mild hypertension can be generalized in a nationwide assessment. The efficacy of nebivolol as monotherapy and as the efficacy as add-on therapy are very similar. Nebivolol is highly efficacious in patients with ISH.
