title: Parenteral administration of GM1 ganglioside to presenile Alzheimer patients.
abstract: The pharmacokinetic parameters of GM1 ganglioside were examined in 16 patients (mean age 64 +/- 5 years) with Alzheimer's disease. The ganglioside was given intramuscularly and subcutaneously. The maximum GM1 blood level was reached after 48-72 h, the subcutaneous route leading to the highest blood levels, but the individual variability was relatively large. When 100 mg GM1 ganglioside was given daily for a week, maximum serum values of 15 to 20 mumol/l were found in 3 patients. The elimination half-life from serum was 60-75 h.
