Pain is a distressfulness feeling mostly caused by intense or damaging stimuli. The International Association for the Study of Pain's widely used definition defines pain as "an hellish sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage". In medical diagnosis, pain is regarded as a symptom of an underlying condition. So the usage of medicines for demolishing such like condition is called Pain Medications.

Pain medications, also known as analgesics, are a type of drugs used to relieve pain. Analgesics either stop pain signals from going to the brain or alter the brain’s interpretation of those signals. Analgesics prevent the brain from processing pain signals, yet do not depend on anesthesia or loss of consciousness to achieve their pain-killing effect.

Non-norcotic pain medications

This type of pain medication are also known as non-opioids. These medications are moderate forms of analgesics and include acetaminophen, the most commonly used over the counter non-narcotic analgesic. Other drugs are not technically part of the analgesic family, but are nonetheless considered analgesics in practice.

Narcotic pain medications

Narcotic pain medications are also called opioids. These medications are powerful analgesics that are used when pain signals are too severe to be controlled by non-narcotic analgesics. Analgesics in this category include natural narcotics (derived from the opium poppy), such as morphine and codeine, and synthetic narcotics, such as propoxyphene (Darvon) and meperidine (Demerol).
