The effect of dietary fiber on postprandial serum digoxin concentration in man.
The postprandial digoxin concentrations in serum were measured for 4 hr by radioimmunological assay in six healthy volunteers who had received 0.8 mg beta-acetyldigoxin by the oral route. Digoxin was given together with a formula diet containing as admixture, respectively, wheat bran, microcrystalline cellulose, pectin, carrageenan, and carob seed flour. The various additions did not reduce the mean digoxin concentrations in serum. After carob seed flour, the concentrations were significantly (P less than 5%) higher, as compared to the control. After microcrystalline cellulose, pectin, and wheat bran the mean peak concentrations were reached later than in the control state.
