Ambroxol Sustained Release 75 mg [Design Issues]

Dear colleagues,

I have been asked to perform a bioequivalence study on ambroxol, sustained release formulations containing 75 mg. according to guideline a single dose fast study as well as a single dose fed may be applicable. The multiple dose study is also required due to accumulation, according to ambroxol half-life between 7 and 12 hours.

I would like to have inputs from experienced researchers in order to aware of any concerns related to this substance.

Kind Regards

Hi Maggie,

Which guideline are you refering? EMA or FDA? Didn't find any product-specific guideline on ambroxol bioequivalence...

If you're refering to a more general guidance, FDA guideline for BE studies with pharmacokinetic endpoints states de following (section IV, D, 3):

For modified release products, we recommend the following studies: (1) a single-dose, fasting study comparing the highest strength of the test with the RLD, and (2) a single-dose fed BE study comparing the highest strength of the test with the RLD product. Because single-dose studies are considered more sensitive in addressing the primary question of BE (e.g., release of the drug substance from the drug product into the systemic circulation), multiple-dose studies are generally not recommended
