Amlodipine and Relpax drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Amlodipine (amlodipine besylate) and Relpax (eletriptan hydrobromide). Common drug interactions include blood alkaline phosphatase increased among females and back disorder among males.

The phase IV clinical study analyzes what interactions people have when they take Amlodipine and Relpax. It is created by eHealthMe based on reports of 93 people who take the same drugs from the FDA, and is updated regularly.

How the study uses the data?

The study uses data from the FDA. It is based on amlodipine besylate and eletriptan hydrobromide (the active ingredients of Amlodipine and Relpax, respectively), and Amlodipine and Relpax (the brand names). Other drugs that have the same active ingredients (e.g. generic drugs) are not considered. Dosage of drugs is not considered in the study.
