Tidsramme |
|---|---|---|
|
Area Under the Curve From Time 0 to t, AUC (0-t)
Tidsramme: Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|
Area under the plasma concentration time curve from zero and extrapolated to the time of last quantifiable sample was determined from plasma concentration time profile of nicotine.
AUC(0 -t) was based on the baseline adjusted nicotine plasma concentration data.
|
Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|

Maximum Plasma Concentration (Cmax)
Tidsramme: Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|
Maximum plasma nicotine concentration was determined from plasma-concentration time profiles.
Cmax was based on the baseline adjusted nicotine plasma concentration data.
|
Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing

Tidsramme: Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|
Tmax was determined from plasma concentration time profiles.
Tmax was based on the baseline adjusted nicotine plasma concentration data.
|
Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing

Rate of Elimination (Kel)
Tidsramme: Blood samples were collected pre-dose at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|
Elimination rate constant for nicotine was calculated.
Kel was based on the baseline adjusted nicotine plasma concentration data.
|
Blood samples were collected pre-dose at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing

Plasma Half Life (t1/2)
Tidsramme: Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
|
Half-life of elimination of nicotine was determined.
t1/2 was based on the baseline adjusted nicotine plasma concentration data.
|
Blood samples were collected pre-dose and at 5, 10, 15, 30 and 45 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10 and 12 hours post dosing
