New drugs on Australia’s PBS schedule:


  • Xatral SR 10mg prolonged release tablets
  • alpha-1 adrenergic blocking agent for use in Rx of benign prostatic hypertrophy, similar to prazosin, tamulosin and terazosin
  • vasodilator so may cause postural hypotension
  • only modest benefit over placebo and no difference in efficacy between the alpha-1 adrenergic blocking agents.


  • Evoltra
  • a purine nucleoside analague used in Rx of paediatric acute lymphocytic leukaemia


  • Circadin 2mg prolonged release tablets
  • a natural hormone available for Rx of primary insomnia in those aged over 55 years
  • only marginal benefits over placebo for most patients with only 30% responding


  • Nebilet 1.25mg, 5mg and 10mg tablets
  • beta1 blocker with mild vasodilatory properties via nitric oxide release
  • used in Rx of hypertension (1.25mg up to max. 40mg once daily) and stable chronic heart failure (1.25mg, gradually increase to 10mg once daily if tolerated)
  • benefits over other beta blockers are not yet clear clinically


  • Maxalt 10mg wafers
  • Rx of acute migraine
  • mainly acts as agonist on 1B and 1D serotonergic receptors
  • more patients respond to 10mg rizatriptan than to 100mg sumatriptan, but headache was more likely to return and necessitate a 2nd dose after 2 hours
  • overall efficacy is similar to sumatriptan


  • Stelara 45mg for injection
  • a humanised monoclonal antibody which suppresses the immune system by blocking the inflammatory actions of IL-12 and IL-23, and is thus used in Rx of unresponsive psoriasis.
  • a s/c dose is given at 0,4 and then every 12 weeks
  • serious side affects include angina, stroke, hypertension, intervertebral disc prolapse, dactylitis, clavicular fracture, sciatica and nephrolithiasis, while one 33 yr old man died suddenly while taking a 90mg dose and the death was thought to be related to a dilated cardiomyopathy
