About the Study
This study will compare two different ways of giving a medicine called atropine to healthy adults. The goal of this study is to find out if atropine sulfate eye drops placed under the tongue are similar in their function to the injection form given in the thigh.
This research is a Bioequivalence – Bioavailability and pharmacokinetics (PK) study, meaning that this study is comparing how different forms of atropine sulfate (the study drug), specifically atropine sulfate eye drops delivered under the tongue (sublingually) and atropine sulfate injection form delivered using a needle into a muscle of your leg (intramuscular or IM), are similar by measuring the level of study drug that becomes completely available in the bloodstream; also, how the body processes and eliminates the study drug. The goal of this research is to find out if atropine sulfate eye drops placed under the tongue has a similar effectiveness in the body as the injected form of atropine given IM. Information learned from this study may help other people in the future.
