    Notes: Abstract Objective: This study was performed to estimate whether the pharmacokinetics and safety of tamsulosin, an α1A-adrenoceptor antagonist for the treatment of symptomatic benign prostatic hyperplasia (BPH), are influenced by impaired renal function. Methods: In an open-label study design, the plasma concentration profile of 0.4 mg tamsulosin p.o. was studied in age-matched groups of male subjects with normal (n = 10), moderately impaired (n = 10), and severely impaired (n = 8) renal function after single-dose administration and in steady state, i.e. after 21 days of multiple-dose administration. Results: The AUC of total, but not of unbound, tamsulosin was correlated to creatinine clearance and α1-acid glycoprotein plasma levels, and was found to be significantly higher in both groups of subjects with impaired renal function than in controls after single- and multiple-dose administration. However, the pharmacokinetics of total and unbound tamsulosin were comparable for both trial periods. Conclusions: Impaired renal function increases total tamsulosin plasma concentration by approximately 100% after single-dose administration and in steady state. Since active unbound drug levels are not affected, no dose modification is required in symptomatic BPH patients with renal impairment.

    Notes: Abstract Only a few longitudinal studies have addressed benzodiazepine use over time. We therefore conducted a 10‐year follow‐up study (1983‐1992) on usage patterns of benzodiazepines in a Dutch community of 13500 people. Use decreased during the time of the study. Twelve (1983) to ten (1992) percent of the inhabitants was a recipient at least once a year of a benzodiazepine prescription. The use by gender showed more women using more prescriptions as men. Women were not prescribed more DDDs per prescription as men. Individual benzodiazepines showed differences in use by gender. Use increased with age among both women and men. Most of the users were 55 years or older. One out of three patients was either an incidental user (1‐30 days use in one calendar year), a regular (31‐180 days), or a long term user (more than 180 days). The use of long half‐life hypnotics decreased, the use of the short half‐life ones showed an increase. Behind a stable overall trend we found strong fluctuations in use of individual benzodiazepines.
