Detailed Description

Metformin glycinate salt is a new drug , which has better pharmacokinetic characteristics (better bioavailability and absorption) making a proper antihyperglycemic power without increasing the frequency of adverse effects. The drug has been tested in preclinical test with animals, in healthy subjects and in patients with type 2 diabetes; which showed that it has adequate antihyperglycemic effect. Now, its important to compare metformin glycinate and metformin hydrochloride for evaluate the relative antihyperglicemic power. In addition, a study with a larger number of patients improve the statistical power of the test to investigate the effects of these drugs on possible weight loss and lipid profile improve. Additionally, it will also explore the relative power of the two medications tested to modify inflammatory response mediators and oxidative stress have been associated with the incidence of cardiovascular disease in diabetes. This project was designed with the intent to answer the next question: What are the efficacy and safety of metformin glycinate dose of 2101.2 mg/day (equivalent to 1700 mg/day metformin hydrochloride), compared with metformin hydrochloride in doses of 1700 mg/day for 12 months of treatment in patients with Type 2 diabetes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
