Comparative effects of imipramine and dothiepin on salivary rate in normal volunteers.

1 Imipramine induced significant reduction in salivary rate compared to placebo in a cross-over, double-blind study of twelve normal volunteers. In contrast, there was no significant difference between the reduction in salivary rate induced by dothiepin and placebo. 2 Comparison of salivary rates showed no significant difference between the drugs in the initial and cross-over treatment periods. However, pooled observations from the initial and cross-over treatment periods indicated that imipramine produced a significantly greater reduction in salivary rate than dothiepin. 3 The results suggest that dothiepin would cause far less dryness of mouth compared to imipramine. This feature might ensure greater therapeutic compliance.
