Small carbonaceous powder containing extensive netwirk of pores.

  • Most effective within 1 hour
  • 1g/kg given orally

Ineffective in:

  • Metals; iron, lithium, lead, cyanide, mercury

  • Forced diuresis
  • Renal dialysis/haemoperfusion
27
Q

For what drug is urine alkalinisation useful against?

A

Aspirin (Acetylsalicylic acid)

28
Q

How doe urine alkalinisation work with aspirin?

A
  • Aspirin is a weak acid
  • Alkalinisation of renal tubular fluid ionises the drug, making it less lipid-soluble
  • This form is unable to diffuse back across and be reabsorbed

In alkaline diuresis urine pH is 7-8

29
Q

How does haemodialysis work?

A

Enhances elimination of

  • Ethanol
  • Ethylene glycol
  • Lithium

  • Sialicylate

*This is the treatment of chioce in severe poisoning

Blood is passed through a membrane of charcoal
