Where clinically appropriate, each example is shown as both a dose-based and product-based instruction.

Omeprazole, 10mg, gastro-resistant, oral, once daily

Trimethoprim, 200mg, oral, twice a day, for 3 days

Sodium citrate / Micralax Micro-enema enema, once daily

Diprobase ointment, 1 application, Topical, 3 times a day

The VTM related to the Diprobase AMP’s is a multi-ingredient concept “White soft paraffin + Liquid paraffin” and cannot be used as a prescribing concept.

Beclometasone 0.025% cream, Apply Thigh, twice a day

Where a concentration is required it is expected that the prescribing concept would be a VMP or AMP.

   <value value="30"/>
   <unit value="millilitres per kilogram"/>
   <system value="http://unitsofmeasure.org"/>
