Impact of Pharmacogenetic-Guided Treatment on Type 2 Diabetes.

The goal of this clinical trial is to assess the efficacy of a pharmacogenetics-guided treatment, compared to standard optimized treatment, in patients with inadequately controlled type 2 diabetes. The main questions it aims to answer are: * Is the disease better controlled when the treatment prescribed is based on the participant's pharmacogenetic profile? * What medical problems do participants experience while taking the treatment? Participants will: * Take the treatment described according to the Summary of Product Characteristics (SmPC). * Visit the clinic once every 12 weeks for checkups and tests. * Keep a diary of their symptoms to inform the Investigator.
