Understanding Analgesics: Types, Functions and Pain Relief Mechanisms

• What is an Analgesic? – An analgesic is a medication designed to relieve pain without causing loss of consciousness.

• How Does It Work? – Analgesics work by blocking pain signals in the nervous system or by altering the brain’s perception of pain.

• Types of Analgesics:

• Non-Opioid Analgesics – Includes over-the-counter medications like acetaminophen and NSAIDs, used for mild to moderate pain.

• Opioid Analgesics – Stronger medications like morphine and oxycodone, prescribed for severe pain.

• Adjuvant Analgesics – Medications like antidepressants and anticonvulsants, used alongside other pain relievers for certain conditions.
