The Pharmacokinetics of Sublingual Atropine

The study of the pharmacokinetics of sublingual atropine drops will help in determining the safety of sublingual atropine. The effect on saliva secretion, blood pressure, pulse rate, and vision will also studied.

Sublingual atropine drops are used frequently in the treatment of clozapine-induced hypersalivation and drooling. To date, no studies have investigated the pharmacokinetics of sublingually administered atropine and if it is different from that of oral atropine.

Participants will be having a single dose of 0.6mg sublingual atropine drops on day 1. On day 2 at least 4 days after day 1 dose: a single 0.6mg dose of atropine tablet to be swallowed. On day 3 at least 4 days after day 2 dose: a single 1.2mg dose of sublingual atropine drops. Participation in all 3 days is ideal but not a must for participation.

Sequential venous blood will be collected over 10 hours at the Charles Perkins Centre-Camperdown, NSW.

A small compensation for travel expenses will be provided at the end of each study day.

Ethics committee approval number: HREC/18/RPAH/687
