Pancreatic enzyme products are formulated, manufactured, and sold without submitting efficacy or bioavailability data to the Food and Drug Administration because of a quirk in the law. We documented therapeutic failures in three patients with cystic fibrosis after pharmacists substituted generic pancrelipase capsules for the Pancrease brand. Gastrointestinal symptoms and fat malabsorption rapidly resolved after therapy was reinstituted with brand name products. In vitro analysis indicated that after 1 hour of exposure to simulated gastric fluid, lipase activity was less than 200 U per capsule from all three generic capsules dispensed to the patients compared with 6820 U per capsule from Pancrease. These data indicate that the enteric coating of the generic product was defective and that the substituted product was not bioequivalent to the prescribed brand. We conclude that the Food and Drug Administration should institute regulations over this group of products.

The occurrence of retinopathy and its relationship to diabetes in 1,640 Pima Indians age 15 and over has been determined. Eighteen per cent of those with two-hour postload plasma glucose levels of equal to or greater than 200 mg./dl. had some evidence of retinopathy. Of those with retinopathy and diabetes, 7 per cent were found to have proliferative or neovascular changes, the remainder having microaneurysms and/or exudates. The frequency of retinopathy increased from 3 per cent among newly diagnosed diabetics to 47 per cent among those with diabetes of 10 or more years duration. No relationship was found with sex, age at diagnosis of diabetes, or age at time of examination when duration of diabetes was taken into account. The occurrence of retinopathy was confined largely to those who fell into the second or hyperglycemic component of the frequency distribution of plasma glucose levels in the population, indicating the significance of the bimodal glucose tolerance frequency distribution.
