A gelatin-based container designed to hold a single dose of medication is called a capsule.
Step-by-step explanation:
A special container made of gelatin that is sized for a single dose is called a capsule. Capsules consist of a gelatin-based shell that can be filled with medication in the form of either liquid or powder. Different from a tablet, a troche, a suppository, or a caplet, a capsule is typically a cylindrical shape and has two halves that are joined together to enclose the medication.
