 Surfactant in Biowaiver media [Dissolution / BCS / IVIVC]

When should surfactant be used in Biowaiver media as guidelines state that the 3 pH medias are done without surfactant?

Thanks,

 Surfactant in Biowaiver media

Hi Amira/Helmut

Which biowaiver we are talking about?
a) If BCS based biowaiver to be proposed then NEVER
b) If biowaiver for strengths other than bio strength: YES but need to provide sufficient justification/Data for usage of surfactant (especially in case of BCS class II/IV drugs, one have to add surfactant to show complete release)

Hi Luv & Amira

❝ Which biowaiver we are talking about?

❝ a) If BCS based biowaiver to be proposed then NEVER

❝ b) If biowaiver for strengths other than bio strength: YES


I assumed a) because Amira wrote

❝ ❝ as guidelines state that the 3 pH medias are done without surfactant


GLs sometimes leave space for interpretation (“should be”, “appropriate”, “if justified”, :blahblah:). However, “The use of any surfactant is not acceptable” is unambiguous.
