Everything above is a field from Drugs@FDA, the FDA Drug Shortage Database, the EMA register or ClinicalTrials.gov. There is no efficacy comparison here and there will not be one: head-to-head claims belong to the trials that made them, and which drug suits a particular person is a question for a clinician.
