4.3 Paediatric powder.

Aim

To prepare a paediatric paracetamol each pack containing 0.25g powder.

Theory

Paracetamol- A white powder, odourless, should be stored in a well ventilated place.10

Codeine phosphate – A white powdered solid, odourless, partially soluble in menthanol, insoluble in diethyl ether, soluble in cold water. Should be stored in an airtight container.11

Lactose ad – A white slightly sweet odourless powder used mostly to bulk powder up, should be stored in an airtight container.12

Formula Original Working

Rx Paracetamol 50mg 1.0g

Codeine phosphate 5mg 0.1g

Lactose ad 250mg 5.0g

Method

1. Weighed codein phosphate and poured 0.1g in a mortar.

2. Weighed 1g paracetamol and added to the mortar, grinded with pestle until fine.

3. 5g-(1g+0.1g) = 3.9g of lactose was added and mixed in the mortar.

4. 3 doses of 0.25g packs were made and folded accordingly.
