ANALGESIA
What are analgesics ?
Analgesics are drugs that relieve pain selectively without blocking nerve conduction, significantly altering sensory perception or affecting consciousness, but by reducing inflammation or by modifying how your brain perceives pain.
Unlike the drugs used for anesthesia during surgery, analgesics do not turn off nerves, do not change the ability to feel your environment, and do not change consciousness. This selectivity is an important distinction between an analgesic and an anesthetic.
Analgesics are used to relieve pain and inflammation. For example:
- For acute pain (sudden, short-term), such as a sprained ankle or headache.
- Due to an injury, such as a broken bone.
- For aches and pains like menstrual cramps or muscle pain.
- After surgery.
- For chronic painful conditions such as arthritis, cancer, or back pain.
What are the types of analgesics ?
Analgesics can be classified into two types :
- Anti-inflammatories: which relieve pain by reducing local inflammatory responses.
- Opioids: which act on the brain. Opioid analgesics were once called narcotics because they can.
cause sleepiness. Opioid analgesics can be used for short-term or long-term relief of severe pain. In contrast, anti-inflammatory drugs are used for short-term pain relief and for moderate pain, such as headaches, muscle aches, bruises or arthritis.
