Ketotifen KETO

An approved allergy medication that also helps keep the body from getting too used to certain stimulant drugs, so it's sometimes used off-label alongside them. Its allergy use is well proven; the other use is based on how the drugs interact rather than dedicated studies.

Also known as Zaditen, Ketotifene, Ketotifeno, Ketotifenum, HC 20-511, X49220T18G, CHEBI:92511, Ketotiphene
