Letter to the editor
Editor, – Roche Products recently announced plans to discontinue production of naproxen suspension in Australia.1 Their letter communicating these plans implies that rofecoxib suspension is a viable alternative. This is irresponsible, for several reasons, and demonstrates a clear lack of consideration of the best interests of children.
First, naproxen suspension is currently the most widely used non-steroidal anti-inflammatory drug (NSAID) in children with chronic arthropathies worldwide.2 It has a well-established efficacy and safety profile in children. The liquid formulation also has a convenient dosage schedule (twice daily) and is affordable. The only other NSAID with demonstrated efficacy and safety in children currently available in liquid formulation in Australia is ibuprofen. However, its lower effectiveness, need for more frequent dosing and greater cost are disadvantages in chronic therapy. The discontinuation of naproxen suspension will therefore mean that children will be unfairly disadvantaged by having their already limited NSAID options even further restricted.
Second, children's risk of significant gastropathy with NSAID therapy is negligible.3 There is therefore little rationale for considering a COX-2 inhibitor in the vast majority of children. Evaluable data regarding their safety/efficacy in children is lacking. The question of whether there is any gastrointestinal safety advantage with COX-2 specific inhibitors,4 the emerging safety concerns in adults,5 and the considerably higher cost, mean that rofecoxib suspension cannot be considered a 'viable alternative' to naproxen suspension for children.
It is time to stop treating children as second class therapeutic citizens and time to start paying more serious attention to ensuring that they have fair and equitable access to appropriate medications.
