When should surfactant be used in Biowaiver media as guidelines state that the 3 pH medias are done without surfactant? Thanks, Edit: Category changed. [Helmut] |

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) — ~A happy Soul~ |

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”,  ). However, “The use of any surfactant is not acceptable” is unambiguous.— Dif-tor heh smusma 🖖🏼 Довге життя Україна!
