ergot alkaloid derivatives

WHO's definition, quoted as written in the 2024 stem book
Names only. This page is about erg as a part of a name. It has nothing on uses, doses, side effects or interactions of any medicine that carries it, and nothing here is medical advice. Ask a pharmacist or doctor about the medicine itself.

Where it sits in a name

WHO writes the stem as erg, without hyphens, which means it can sit anywhere in a name. So the letters erg sit anywhere in the name (erg).
