digoxin and Intracranial-Hypertension

Fourteen obese patients (body mass index = 34-47 kg/m2; mean = 40 kg/m2) with lumbar cerebrospinal fluid pressure (Pcsf) above 20 cm water in 10 of the 14 patients were treated with digoxin with a serum concentration of at least 1.0 nmol/L (0.8 ng/ml) for 6 months. Pcsf decreased significantly during digoxin medication (p < 0.005). Although there were no diet restrictions, all patients decreased in weight (range: 3-25 kg; mean = 10.6 kg) during the 6 months (p < 0.001). When digoxin medication was stopped in 3 patients, prompt weight increase occurred. Most patients needed progressively increased digoxin doses to attain stabilized serum concentrations at the stipulated level, in 5 patients more than 0.5 mg a day. Five of 13 patients developed diabetes mellitus during the digoxin medication. The larger the dose of digoxin, the greater the risk for diabetes mellitus to occur.
