Coated Tablet (dose form) mapping in BDPM #408

Open scossin opened 3 years ago

scossin commented 3 years ago

In French, "comprimé pelliculé" means "film-coated tablet".

Film coating is a common step in tablet manufacture that can be used to improve product appearance, organoleptic properties, or to facilitate swallowing. Functional film coats can also be used as a part of the product's stabilisation strategy and to modify or delay drug release.

I'm not a pharmacist but as I understand it, the purpose of film coating is not always to delay drug release. So it may not be correct to map "coated oral tablet" of BDPM to "delayed release oral tablet" of RxNorm.

Changing this relation will impact many drug products relations as you can see in the example below:

coated_tablet

"ABACAVIR MYLAN 300mg, comprimé pelliculé sécable" is mapped to "abacavir 300 MG Delayed Release Oral Tablet Box of 60 by Mylan", I think the correct mapping is "abacavir 300 MG Oral Tablet Box of 60 by Mylan".

Hi Sebastién, I agree coated tablet should not necessarily be equal to delayed release tablet. Looks like we would need to do some review and fine tuning here.
