Time-released garlic powder tablets lower systolic and diastolic blood pressure in men with mild and moderate arterial hypertension.

Numerous clinical investigations that have focused on the hypotensive effects of garlic-based preparations have led to controversial results that may be partially because of differences in the composition of the preparations and in the biological responses they induce. It is possible that garlic powder tablets with a prolonged mode of action could induce more potent biological effects. In this double-blind, placebo-controlled trial with an active control arm, the hypotensive action of time-released garlic powder tablets (Allicor) was compared with that of regular garlic pills (Kwai) in 84 men with mild or moderate arterial hypertension. After an 8-week placebo treatment run-in phase, patients were randomized either to 600 mg Allicor (n=30) or to placebo (n=20) daily for 8 weeks. In addition, in the open-label branch, patients received either 2400 mg Allicor daily (n=18) or 900 mg Kwai daily (n=16). Allicor treatment (600 mg daily) resulted in a reduction of both systolic and diastolic blood pressures by 7.0 mm Hg (95% confidence interval (95% CI): 5.3-8.7) and 3.8 mm Hg (95% CI: 2.7-4.8), respectively. Increasing the Allicor dosage to 2400 mg daily did not provide any additional benefit. Treatment with Kwai resulted in the same decrease in systolic blood pressure (5.4 mm Hg, 95% CI: 1.9-8.8) as that seen with Allicor, but no decrease in diastolic blood pressure was observed with Kwai. Different effects of Allicor and Kwai on diastolic blood pressure may be because of the prolonged action of Allicor, which allows better bioavailability of the vasoactive constituents of garlic powder. The results of this study show that time-released garlic powder tablets are more effective for the treatment of mild and moderate arterial hypertension than are regular garlic supplements.

Metabolic effects of time-released garlic powder tablets in type 2 diabetes mellitus: the results of double-blinded placebo-controlled study.

Late complications in type 2 diabetic patients are commonly associated with accelerated development of atherosclerosis. In type 2 diabetes mellitus, non-enzymatic glycosylation of apo-B that is a function of hyperglycaemia is an efficient biochemical way of low-density lipoprotein atherogenic modification. So, proper metabolic control is needed to prevent late complications of diabetes. The study was performed to estimate the effects of time-released garlic powder tablet Allicor on the parameters of metabolic control and plasma lipids in type 2 diabetes mellitus. The metabolic action of Allicor was investigated in the 4-week double-blinded placebo-controlled study in 60 type 2 diabetic patients. Fasting blood glucose was measured daily, and serum fructosamine as well as cholesterol and triglyceride levels were determined at the baseline, after 1, 2, 3 and 4 weeks. It has been demonstrated that treatment with Allicor resulted in better metabolic control due to the lowering of fasting blood glucose, serum fructosamine and serum triglyceride levels. The results of this study may allow recommending garlic powder tablets Allicor for the treatment of type 2 diabetes mellitus along with dietary treatment and/or sulfonylurea derivatives to achieve better metabolic control. The benefits from garlic preparations may lead to the reduction of cardiovascular risk in diabetic patients.
