How this group is made

Each product is placed by the ATC code in its national register record (Bulgaria) or by the pharmacologic class the FDA assigned it (United States). Products without either are in no group rather than in a plausible one.

A group is not a diagnosis. Medicines are grouped by the class the regulator gave them. Which one suits you depends on things this page cannot know — ask a pharmacist or doctor.
