Pharmacokinetics of temocapril and temocaprilat after 14 once daily oral doses of temocapril in hypertensive patients with varying degrees of renal impairment.

Aims: The aim of this study was to determine the potential influence of renal impairment on the pharmacokinetics of temocapril and its pharmacologically active diacid metabolite, temocaprilat.

Methods: Non-compartmental pharmacokinetics were assessed in four groups of hypertensive patients (n=8 per group, four investigational centres) with normal (creatinine clearance determined via 24 h urine sampling, CL[CR], > or = 60 ml min-1) and impaired renal function (CL[CR] 40-59, 20-39, < 20 ml min-1) after 14 once daily oral doses of 10 mg temocapril hydrochloride.

Results: For temocapril, there were no statistically significant differences in median tmax or mean Cmax, AUC(SS), t1/2,Z, CL/F between the four groups.

Comparison of temocapril and atenolol in the long-term treatment of mild to moderate essential hypertension.

This 1-year, dose-titration, General Practitioner (GP) study compared efficacy, tolerability and safety of oral temocapril (10-40 mg once daily) with atenolol (25-100 mg once daily) in mild to moderate adult hypertensives (diastolic blood pressure (DBP) 95-114 mmHg). A 12-week dose-titration period, randomized 3:1 temocapril: atenolol, preceded 40 weeks long-term treatment. An intent-to-treat population of 472 patients was analysed for efficacy after 12 weeks dose-titration.

Single-dose pharmacokinetics of temocapril and temocapril diacid in subjects with varying degrees of renal impairment.

Objective: The aim of this study was to determine the influence of renal impairment on the single-dose pharmacokinetics of temocapril and its pharmacologically active metabolite, temocapril diacid.

Methods: A single oral dose of 20 mg temocapril hydrochloride was given after an overnight fast to eight healthy (control) subjects (group A, n = 8) with a mean baseline creatinine clearance (CLCR) of 115.2 ml.

Inhibition of expression of human immunodeficiency virus-1 in vitro by antibody-targeted liposomes containing antisense RNA to the env region.

Previous studies revealed that antisense oligodeoxynucleotides to specific regions of the human immunodeficiency virus-1 (HIV-1) are potent inhibitors of replication of HIV-1 in vitro (Zamecnik, P. C., Goodchild, J.

Alteration of DNA topoisomerase II activity during infection of H9 cells by human immunodeficiency virus type 1 in vitro: a target for potential therapeutic agents.

Infection of H9 cells with human immunodeficiency virus type 1 (HIV-1) was found to decrease the phosphorylation of DNA topoisomerase II during the initial phase of infection. Simultaneously, with a later overshoot of phosphorylation and the subsequent activation of DNA topoisomerase II, the production of HIV-1 started. Applying three new protein kinase C inhibitors from the class of O-alkylglycerophospholipids we demonstrated that inhibition of protein kinase C-mediated phosphorylation of DNA topoisomerase II resulted in an inhibition of HIV-1 production.
