Generics makers have a whole host of new bioequivalence documents to go through. The US Food and Drug Administration (FDA) announced on 27 January 2016 that it had released 35 new draft guidance documents and 12 revisions to guidance documents on bioequivalence requirements for the development of generics containing 42 different active ingredients.

The new draft bioequivalence guidance documents cover generics of oral contraceptive ethinyl estradiol/norethindrone acetate, antipsychotic Zyprexa (olanzapine), corticosteroid drug prednisone and acid relux treatment Zantac (ranitidine), among others, see Table 1.

Revised bioequivalence guidance documents include those for generics of menopause hot flashes treatment drospirenone/estradiol, attention deficit hyperactivity disorder (ADHD) treatment Estulic/Tenex (guanfacine) and Alzheimer’s/Parkinson’s Disease treatment Exelon (rivastigmine), see Table 2.

The draft guidance documents recommend what in vivo and in vitro studies generics companies should carry out in order to demonstrate bioequivalence. The number of studies, the population to be studied, blood sampling time points and analytes to be measured in blood samples are also detailed in the draft guidance documents.

In total, FDA now has 1,397 product-specific guidelines with bioequivalence study recommendations. The agency also has an overarching guidance document on bioequivalence recommendations for specific products [1].

Comments on the draft guidance documents can be posted to the Division of Dockets Management (DDM) under Docket FDA-2007-D-0369-0015. This can be done via the website www.regulations.gov or written comments can be mailed to DDM (HFA-305), FDA, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.
