4 Pharmacology and Biochemistry

4.1 Absorption, Distribution and Excretion

Two male patients with late stage (uremic) infantile nephropathic cystinosis (INC) were treated by mouth with the reducing agent dithiothreitol (DTT), at doses not exceeding 25 mg/kg body weight three times per day. Three sequential periods of observation were obtained in both patients: on thiol (8.5 months); off thiol (8-9 months); on thiol again (7 months or longer)... Whereas chemical methods are not reliable for detecting and measuring DTT in biologic fluids, preliminary evidence indicates that a silylated derivative of oxidized DTT can be detected in the urine of patients receiving DTT by mouth. This finding suggests that the thiol is absorbed and excreted.
