Pills

A pill is a small, round, solid pharmacological oral dosage form that was in use before the advent of tablets and capsules. Pills were made by mixing the active ingredients with an excipient such as glucose syrup in a mortar and pestle to form a paste, then rolling the mass into a long cylindrical shape (called a "pipe"), and dividing it into equal portions, which were then rolled into balls, and often coated with sugar to make them more palatable.
In colloquial usage, tablets, capsules, and caplets are still often referred to as "pills" collectively.
