#3: > Aber zum Glück passen die anderen Belege
For the AkdÄ and AMK certainly, but they don't really fit the OP. All the links in #1 are direct translations from the German and, if that’s the official designation, that’s what you have to use for the DCGMA.
However:
OP > In diesem Fall geht es um einen Krankenhausapotheker, der an der Arzneimittelkommission mitwirkt:
Außerdem gibt es oft an Krankenhäusern Arzneimittelkommissionen, die festlegen, welche Arzneimittel in der Klinik durch die Krankenhausapotheke vorgehalten und durch Ärzte routinemäßig verordnet werden sollen.
#1 > In addition, there are often drug commissions in hospitals
Most hospitals don’t have “drug commissions” to decide on the hospital formulary (the list of drugs that may be prescribed). It would be the Pharmacy and Therapeutics (P&T) Committee in the US ( https://www.ashp.org/-/media/assets/policy-gu... ) and the Formulary Committee in the UK ( https://www.guysandstthomas.nhs.uk/about-us/p... )
So unless the pharmacist in the OP is a member of the federal body, it would be better to use either P&T or formulary committee for a regional or local hospital, depending on whether intended for an AE or BE readership.
