Tenoretic (Atenolol / Chlorthalidone) - Summary

 
 



TENORETIC SUMMARY

TENORETIC
(atenolol and chlorthalidone)

TENORETIC® (atenolol and chlorthalidone) is for the treatment of hypertension. It combines the antihypertensive activity of two agents: a beta1-selective (cardioselective) hydrophilic blocking agent (atenolol, TENORMIN®) and a monosulfonamyl diuretic (chlorthalidone).

TENORETIC is indicated in the treatment of hypertension. This fixed dose combination drug is not indicated for initial therapy of hypertension. If the fixed dose combination represents the dose appropriate to the individual patient's needs, it may be more convenient than the separate components.

Published Studies Related to Tenoretic (Atenolol / Chlorthalidone)

[A comparative study of atenolol (Tenormin) and the combined preparation atenolol/chlorthalidone (Tenoretic Mite) in essential hypertension. A randomized double-blind study from general practice] [1990.04.09]
Two hundred and ninety-two hypertensive patients from general practice who had previously been treated with a diuretic with insufficient effect participated in a randomised trial for a period of three months. A total of 115 patients completed treatment with 50 mg atenolol (Tanormin) and 121 were treated with the combined preparation consisting of 50 mg atenolol and 12.5 mg chlothalidone (Tenoretic Mite) while 56 patients defected from the trial.

Assessment of a fixed-dosage combination of atenolol and chlorthalidone (Tenoretic) in hypertensive Nigerians. [1990.03]
The antihypertensive effect of a fixed dosage combination of the cardioselective beta-adrenoceptor blocker, atenolol, and the oral thiazide-like diuretic, chlorthalidone (Tenoretic) was studied in 24 hypertensive Nigerians in a double-blind, cross-over comparison with three other treatments... The drugs were well tolerated.

Atenolol and chlorthalidone therapy for hypertension: a double-blind comparison. [1988.11]
In a randomized, double-blind, parallel-group study of 31 patients with mild to moderate hypertension, we compared a placebo regimen with a regimen of atenolol and chlorthalidone (Tenoretic). The study, which lasted seven weeks, began with a single-blind two-week placebo lead-in period, followed by a four-week double-blind treatment phase, and concluded with a one-week single-blind placebo washout period.

Clinical Trials Related to Tenoretic (Atenolol / Chlorthalidone)

EBMtrialcentral- Comparing Initial Diuretic Therapies Using a Collaborative Network [Not yet recruiting]

- Clinical equipoise exists with respect to the important question, "What is the best

initial diuretic for the treatment of Hypertension"? A pragmatic comparative effectiveness research (CER) study comparing Chlorthalidone to Hydrochlorthiazide could help inform decision making for this common problem.

- The investigators aim to harness both the power of bioinformatics (using web-based

data-capture and electronic health records) and of online media (through collaboration) in order to facilitate such a CER in "usual-care" settings. This process may also provide a foundation for testing a wealth of important clinical questions which commonly arise in the delivery of contemporary healthcare and would otherwise be left unanswered.

- To this end the investigators are developing a website, EBMtrialcentral, where eligible

physicians can go online and join their collaborative network. Physicians can then enroll eligible patients in this study. These will include under-served urban patients. Clinical information will be entered online (using a secure database housed at Johns Hopkins), patient consent will be obtained electronically and treatment recommendations will be randomly allocated to either 25mg daily of oral HCTZ or 12. 5mg daily of oral Chlorthalidone. The investigators aim to increase to 50mg HCTZ and 25mg Chlorthalidone over 8 weeks and compare their effects on BP measured with a 24 hour monitor.

- The investigators' primary hypothesis is that non-blinded, random, parallel allocation

of 12. 5mg daily Chlorthalidone (titrated to 25mg at 4 weeks) will demonstrate a clinically meaningful ≥5mmHg improvement in BP control (as measured by change in BP from baseline using 24hr ABPM) compared to 25mg daily HCTZ (titrated to 50mg at 4 weeks) in newly hypertensive patients followed in a usual-care clinic setting over 8 weeks. They will also analyze differences in side-effects or safety (serum electrolytes) between these two medications.
