Oral neostigmine and lymphatic absorption in a myasthenia gravis patient on continuous ambulatory peritoneal dialysis (CAPD)

The effects of oral neostigmine on peritoneal lymph absorption and transcapillary and net ultrafiltration were studied in a myasthenia gravis patient on continuous ambulatory peritoneal dialysis (CAPD). Oral neostigmine decreased lymphatic absorption, but only up to a threshold dose. The effect on net ultrafiltration however was nullified to some extent by a concurrent decrease in cumulative transcapillary ultrafiltration.
