propranolol, a prototypical b-adrenergic receptor antagonist and atenolol, a cardio-selective b-antagonist are widely used in therapeutic regimens for treatment of hypertensive patients. in iran, several pharmaceutical manufacturers formulate these two b-blockers. as the formulation of a dosage form is essential for the patient's safety and drug efficacy, in this study we aimed to evaluate...

The effects of atenolol, a new beta1-blocking drug, on pulse rate, sweating, and blood glucose levels during insulin-induced hypoglycaemia were studied in a double-blind crossover trial in eight normal subjects using placebo and propranolol as reference agents. The intensity of induced hypoglycaemia was identical for atenolol, propranolol, and placebo. Propranolol prolonged hypoglycaemia, but a...

• In most of the RCTs analyzed by these investigators, atenolol was the beta-blocker used for comparison. Worldwide, atenolol is one of the most prescribed beta-blockers. • Their analysis indeed suggests that atenolol does not give hypertensive patients adequate protection against cardiovascular disease (CVD). These investigators failed to recognize that beta-blockers possess important and subt...

The effects on ventilatory and cardiac function of atenolol, a new cardioselective beta-adrenoceptor blocking agent, were compared with those of practolol in a double-blind trial in 12 patients with asthma. Both drugs impaired ventilatory function--atenolol insignificantly and practolol significantly. Atenolol was if anything more cardioselective than practolol. Neither drug interfered signific...

OBJECTIVE To study the effects of losartan and atenolol on glucometabolic parameters in nondiabetic hypertensive patients. MATERIALS AND METHODS In a prospective, open-label, parallel group study, nondiabetic patients with mild to moderate hypertension were randomized to either losartan (titrated from 50 to 100 mg/day, n = 20) or atenolol (titrated from 25 mg to 100 mg/day, n = 20) for period...

This paper describes a high-performance liquid chromatography method for the determination of atenolol in human plasma. Atenolol and the internal standard, metoprolol, were extracted from plasma by using a liquid-liquid extraction method. The method was developed on an Ace C18 reverse-phase column using a mobile phase of methanol-water (50:50, v/v) containing 0.1% trifluoroacetic acid. The cali...

Lower melatonin level, melatonin receptor gene variations, and atenolol treatment are associated with glucose dysregulation. We investigated whether atenolol-related glucose and melatonin changes are correlated, and whether single nucleotide polymorphisms (SNPs) in melatonin candidate genes contribute to interindividual variation in glucose change. Hypertensive Caucasians (n = 232) from the Pha...

Nebivolol, β1 selective drug is a third generation β blocker with nitric oxide donating antiproliferative and antioxidant properties which are useful to maintain a proper metabolic profile compared to atenolol, a β1 selective drug most commonly used. A prospective randomized parallel double blind study was conducted in patients with essential hypertension. Group A received nebivolol and group B...

161 Abstract: Pulsatile systems are best for the drugs, which follows chronopharmacological behaviour where night time dosing is required, drugs having high first-pass effect and having specific site of absorption in GIT. In this study, colon targeted pulsatile release tablets of atenolol was prepared using press coating technique to treat hypertension in the early hours of the morning. Pulsati...
