What are central analgesics?

Aspirin-like drugs, paracetamol and amidopyrine exert their analgesic action predominantly at the site of origin of pain, e.g. in inflamed or functionally altered tissues. Opioids are thought to inhibit processing of pain-related neuronal inputs in the CNS including the spinal cord.

How do central analgesics relieve pain?

Analgesics are a class of drugs used to relieve analgesia (pain). They work by blocking pain signals to the brain or interfering with the brain’s interpretation of those signals.

What produces analgesia by acting on the central nervous system?

Nonsteroidal anti-inflammatory drugs (NSAIDs) act upon peripheral tissues and upon the central nervous system to produce analgesia.

What is systemic analgesia?

What causes analgesia?

Analgesia, loss of sensation of pain that results from an interruption in the nervous system pathway between sense organ and brain. Different forms of sensation (e.g., touch, temperature, and pain) stimulating an area of skin travel to the spinal cord by different nerve fibres in the same nerve bundle.

Does morphine act as a sedative?

Rietjens et al1 compared the practices of palliative sedation and euthanasia in the Netherlands. Two conclusions deserve further attention. In 36% of the patients, palliative sedation was performed with morphine only.

How are analgesic drugs affect the central nervous system?

Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which temporarily affect, and in some instances completely eliminate, sensation.

Which is the most common over the counter analgesic?
