Key Points: Analgesics and Antipyretics
Analgesics:
Drugs that relieve pain without causing loss of consciousness
Two types:
| Type | Example | Key Feature |
|---|---|---|
| Non-narcotic | Aspirin, Paracetamol | No addiction; safe |
| Narcotic | Morphine, Codeine | Acts on the CNS; causes addiction |
Aspirin: also antiplatelet (prevents blood clotting)
Antipyretics:
Drugs that reduce fever (body temperature)
Example: Paracetamol (also analgesic)
Artificial Sweetening Agents:
| Agent | Key Fact |
|---|---|
| Saccharin | First artificial sweetener |
| Aspartame | Not used in heating (unstable) |
| Alitame | More stable than aspartame |
| Sucralose | Chlorinated derivative of sucrose |
