Hint: Analgesic is a painkiller

Analgesics, also called painkillers, are medications that relieve different types of pain — from headaches to injuries to arthritis.

An antiseptic is a substance that stops or slows down the growth of microorganisms.

Antihistamines are those compounds that prevent the interaction of histamine with its receptor.

Antacids are used for the treatment of acidity.
