Dialysis clearance and drug recovery of theophylline were investigated in three peritoneal dialysis patients and the results were compared with those obtained from five hemodialysis patients. Peritoneal clearance averaged 9.5 ml/min, in contrast with the hemodialysis clearance of 84.8 ml/min, indicating a relative inefficiency of peritoneal dialysis with regard to theophylline removal. Theophylline half‐life was reduced substantially during hemodialysis, 2.0 to 3.2 hours, in comparison with the normal half‐life range of 4.7 to 6.8 hours during peritoneal dialysis. The fraction of theophylline recovered by peritoneal dialysis approximated 3.2 per cent of dose, while hemodialysis recovered up to 40 per cent of the administered dose. The overall observations of half‐life, dialysis clearance, and drug recovery suggest a clear advantage of hemodialysis over peritoneal dialysis for theophylline detoxification. However, peritoneal dialysis may be preferred to hemodialysis for uremic patients requiring theophylline therapy. Since the removal of theophylline by peritoneal dialysis is minimal, an undesirable alteration of the theophylline dosage regimen in association with dialysis therapy can thus be avoided.
