Effect of transdermal scopolamine on salivation.

The effect of transdermal scopolamine on salivary flow and composition was analyzed in 21 healthy volunteers. The flow rate of whole saliva was significantly lowered by transdermal scopolamine. Significant positive correlations were found between the placebo rate of flow and both the quantity and percentage decreases in response to transdermal scopolamine. The magnesium concentration was significantly increased during transdermal scopolamine administration, whereas the sodium, potassium, and calcium concentrations were not consistently altered. Accordingly, the magnesium secretion rate was unaltered, whereas sodium, potassium, and calcium secretion rates were significantly lowered by transdermal scopolamine administration.

Age differences in effects on blood pressure, flicker fusion frequency, salivation and pharmacokinetics of single oral doses of dothiepin and amitriptyline.

Blood pressure, critical flicker fusion frequency (CFF), salivary flow rate and pharmacokinetics were compared in 7 young healthy volunteers (average age: 22.7 years) and in 7 elderly healthy volunteers (average age: 70.6 years) after single oral doses of the antidepressants dothiepin (DP) 25 mg and amitriptyline (AMP) 25 mg. Systolic blood pressure fell further and the reduction lasted longer in the elderly than in the young after both drugs. The decrease in CFF after AMP 25 mg, and the reduction in salivary flow rate after either DP 25 mg or AMP 25 mg were larger in the elderly than in the young. Plasma levels, T1/2 and Cl of both drugs in the elderly were also higher, longer and smaller, respectively, in the elderly. Clearance was found to be reduced in the elderly. More cautions dosage regimens of these drug should be considered for elderly patients.
