Obesity Clinical Trial - Effect of Tadalafil on Insulin Secretion &

Status Completed

Clinical Trial Summary

Obesity is a chronic disease of multifactorial etiology that develops from the interaction of the influence of nutritive , metabolic , cellular and molecular psychological factors.

Tadalafil is Is a drug inhibiting the enzyme phosphodiesterase-5 (PDE-5), responsible for inactivating the vasodilator nitric oxide. USING paragraph was mainly treat erectile dysfunction, and recently approved for the treatment of pulmonary hypertension , it is innovative because of its longer life means, provides efficacy after 36 hours and the highest selectivity.

The aim of this study is to evaluate the effect of tadalafil on insulin sensitivity and insulin secretion in obese men.

The investigators hypothesis is that the administration of tadalafil improve the insulin sensitivity and insulin secretion in obese men.

Clinical Trial Description

A randomized, double-blind, placebo-controlled clinical trial in 18 men aged between 30 and 50 years with obesity (BMI 30-39.9) according to the World Health Organization (WHO) criteria without treatment.

They will be assigned randomly in two groups of 9 patients, each to receive 5 mg of tadalafil or placebo every day at night during 28 days.

There will be evaluated Insulin secretion, both first phase of insulin secretion by Stumvoll Inex as well as Total Insulin Secretion by Area Under the Curve of glucose and insulin and Insulinogenic Index, and Insulin sensitivity by Matsuda index.

Waist circumference, glucose and insulin levels, lipid profile and blood pressure are going to be load will be evaluated before and after intervention in both groups.

Statistical analysis will be presented through measures of central tendency and dispersion, average and deviation standard for quantitative variables; frequencies and percentages for variable qualitative. Qualitative variables will be analyzed by X2, will be used for differences inter-group Mann-Whitney U Test and Wilcoxon Test for the within-groups differences. Will be considered statistical significance p ≤0.05.

This protocol was approved by a local Ethics Committee and written informed consent will be obtained from all volunteers. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
