Abstract:
Self-administering drops can be a daunting task for many patients. The authors describe a method of drop administration that allows a patient to accurately place drops without the need for special devices or touching the eye. With the bottle of drops held upside down, the back of the thumb is rested on the forehead to stabilize the bottle. The bottle tip can be seen over the eye. The other hand retracts the inferior lid to catch the drop. Poor compliance is common and is often caused by difficulties with drop administration. This simple technique may improve compliance.

Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
