Clinical Trial to Evaluate the Efficacy of a Dyslipidemic Therapy in Mexican Population

Study Overview
=================
Brief Summary
-----------------
Clinical Trial Phase III, experimental, simple blind, randomized with two treatment groups, multicentric, longitudinal, to evaluate the therapuetic efficacy to dislipydemias in mexican adult population. This trial includes homogeneus populations that could be comparable by their disease condition, biologic characteristics and sociodemographics characteristics. 2 Treatment groups: Experimental Group: Oral Administration of L-carnitine (1g) + Oral Atorvastatin (20mg), every 24 hours for 6 months. Active control group: Oral Administration of Atorvastatin 20mg every 24 hours for 6 months. Sample Size: 120 subjects, females or males between 35 to 75 years old. Laboratory tests: Hematic biometry, quimical blood components, electrocardiogram and pregnancy urinary test.

Detailed Description
-----------------
General objectives: Evaluate the therapeutic efficacy in Mexican adults with dyslipidemia through the oral route use of L-carnitine + atorvastatin in comparison with the use of Atorvastatin, after six months of treatment. Evaluate the safety of the medicines under study. Hypothesis: The combined use of L-carnitine + atorvastatin offers therapeutic superiority with respect to the use of atorvastatin as treatment to reduce the percentage of C-LDL in patients with dyslipidemia. The combination of L-carnitine + atorvastatin shows fewer incidences in the presence of adverse events attributable to the medicine in comparison to the use of atorvastatin as mono-therapy, in the treatment of dyslipidemia patients. Design: Phase III clinical assay, experimental randomized with two treatment, multi-centered, longitudinal, to evaluate the therapeutic efficacy in dyslipidemias of Mexican adults. Material and Methods: Sample Size 120 subjects will be included. Inclusion Criteria Mexicans between 35 and 75 years of age. Gender indistinct. Patient with abnormal lipid profile considered as serum levels of C-LDL of 100mg/dl or greater obtained by laboratory parameters.
