What do you call a specific measured amount of medicine?

The term that refers to a specific measured amount of medicine is "Dose." In the context of pharmacology and medicine, a dose is defined as the quantity of a medication that is administered to a patient to achieve a therapeutic effect. It is crucial for both safety and efficacy; administering too much or too little can result in ineffective treatment or harmful side effects.

While volume refers to the three-dimensional space an object occupies, in medical terms it is often related to the physical capacity of a fluid, not specifically about the amount of medicine prescribed for treatment. Unit typically refers to a standard measure used to quantify something, which may not specifically denote a measured amount of medicine. Quantity is a broader term that simply denotes the amount of something and does not specifically convey the context of medicine use, where precision is necessary for effective treatment.
