Primary Outcome Measures:
  • It is estimated that the plasma maximal concentration of galantamine (Cmax=31.53mg×L-1) after single oral administration can be reached in Chinese young volunteers at the peak time of 1.66 hours. The half life is 7.06 hours.

Secondary Outcome Measures:
  • The relative bioavialibility of galantamine oral solution (4mg) indicated by AUC0-t and AUC0-inf are 105.6%±18.5% and 106.2%±19.5% respectively.

Enrollment: 2
Study Completion Date: September 2004
Detailed Description:
This is an open-label, single dose, two-treatment, two-period, cross-over study to evaluate the pharmacokinetic profile and tolerability of galantamine oral solution and galantamine tablet. All patients are healthy male patients who are 18-45 years old with BWI (Body Weight Index) between 18-28 kg/m2. All patients must sign informed consent before being enrolled. 24 patients were randomized in the study. The duration of study is 9 days. All patients must stay at site unit for 12 hours after single oral administration otherwise patients could stay home but must return to site at specific date and time. The day before dosing day (baseline), patients were randomized to one of the two groups to be administered either 4mg galantamine oral solution (1ml) or galantamine tablet (1 tablet). After 7-day washout period, patients were crossed over to receive the other formulation. Pharmacokinetic observation will last to 32 hours after dosing. Plasma were collected at immediately before dosing and 0.25, 0.5, 0.75, 1.5, 2, 3, 4, 6, 8, 12, 24 and 32 hours after dosing to determine plasma concentration of galantamine. Safety and tolerance evaluation will last until Day 9. Safety evaluation include adverse events, vital signs, physical examination, electrocardiogram and laboratory tests. On study Day 1, patients will take either 4mg galantamine oral solution (1ml) or 4mg galantamine tablet (1 tablet). After 7-day washout period, on Day 8, patients will cross over to take the other formulation, the dosage and administration are the same.

  • Patient has donated blood within 60 days prior to dosing
  • Patient is a moderate or severe smoker who smokes more than 3 cigarettes, or ex-smokers who has ceased smoking for at least 3 months prior to dosing
