Resumo
The pharmacokinetics of two fluoxetine capsulated dosage forms and two amitriptyline tablet forms after a single oral intake was studied in dogs and healthy volunteers. High significant correlations were detected between plasma concentrations of fluoxetine (r=0.96, p<0.00001, n=11) and amitriptyline (r=0.78, p<0.0224, n=8) in dogs and volunteers. A correlation of medium strength (though insignificant) was detected between nortriptyline concentrations in the plasma of dogs and volunteers (r=0.69, p<0.199, n=5). The bioavailability parameters of the test drugs in dogs and volunteers did not differ. Similar trends of fluoxetine and amitriptyline pharmacokinetic parameters were revealed in volunteers and animals. Methods for extrapolation of experimental pharmacokinetics parameters of fluoxetine and amitriptyline obtained on dogs for humans are proposed and validated.
