3. the art or science of treating disease with drugs or curative substances, as distinguished from surgery and obstetrics.
4. the medical profession.
5. (among North American Indians) any object or practice regarded as having magical powers.
–verb (used with object)
6. to administer medicine to.
—Idioms
7. give someone a dose or taste of his or her own medicine, to repay or punish a person for an injury by use of the offender's own methods.
8. take one's medicine, to undergo or accept punishment, esp. deserved punishment: He took his medicine like a man.

medicine is a drug.it's a medication if you take it.

Medication is the activity of taking medicine and medicine is the medicine itself that you take.

i'd think medication is more for a chronic problem, and medicine is like asprin or whatever. really, the same thing though...
