The parents of a 6-month-old baby have brought their child to see you due to ongoing problems with reflux.

The baby has been seen in paediatric outpatients and was started on ranitidine. You can see from the clinic letters that this was started at an initial dose of 1 mg/kg three times a day but to achieve symptom control it has been titrated to 3 mg/kg TDS. The higher dose seems to be controlling symptoms well.

The paediatricians have asked you to continue to prescribe the ranitidine at a dose of 3 mg/kg until they review the child again in four weeks time.

You weigh the child today and the current weight is 6 kg. Ranitidine oral solution is dispensed at a concentration of 75 mg/5 ml.

What is the correct dosage in millilitres to prescribe?
