Active Comparator: IR formulation
Healthy volunteers will receive imediate release formulation of Huperzine A (0.4mg)
|
Drug: Huperzine A
Each volunteer will receive single dose of three different formulations of Huperzine A. One immediate release formulation of 0.4mg and two different controlled release formulations at same dose. Between the study phases will be a washout period of at least 21 days.
|
Experimental: CR 1
CR formulation Healthy volunteers will receive controlled release formulation 1 of Huperzine A (0.4mg) |
Drug: Huperzine A
Each volunteer will receive single dose of three different formulations of Huperzine A. One immediate release formulation of 0.4mg and two different controlled release formulations at same dose. Between the study phases will be a washout period of at least 21 days.

Experimental: CR 2
CR formulation Same volunteers will receive controlled release formulation 2 of Huperzine A (0.4mg) |
Drug: Huperzine A
Each volunteer will receive single dose of three different formulations of Huperzine A. One immediate release formulation of 0.4mg and two different controlled release formulations at same dose. Between the study phases will be a washout period of at least 21 days.
