# SUMMARY:

                        The Food and Drug Administration (FDA) is announcing the availability of additional draft and revised draft product-specific bioequivalence (BE) recommendations. The recommendations provide product-specific guidance on the design of BE studies to support abbreviated new drug applications (ANDAs).

The BE recommendations identified in this notice were developed using the process described in that guidance.
