On March 15 1989, the Department of Health (DOH) issued Administrative Order Number 67 series of 1989 entitled Revised Rules and Regulations on Registration of Pharmaceutical Products. This required drug manufacturers to register certain drug and medicine products with the Food and Drug Administration (FDA) before release to the public, and to submit satisfactory bioavailability/bioequivalence (BA/BE) test results to secure a certificate of product registration (CPR). This requirement, however, was put on hold because there was no local facility capable of conducting the test. In 1997, the FDA issued Circulars Numbers 1 and 8 resuming the implementation of the requirement for the BA/BE testing.
