French firm Valois has just developed a closed pump system for nasal sprays which protects the clean, sterile internal contents inside from the bad, bacteria laden world of the outside. Which means that your Rhinocort Aqua won’t need preservatives anymore, which means less irritation of the mucous membranes and fewer side effects.
According to in-PharmaTechnologist.com:
… there is a shift towards minimising the use of preservatives in medicines, and Germany has already implemented a ban on benzalkonium chloride, a preservative often used in nasal formulations. This has already prompted some manufacturers – including Servier, AstraZeneca and Novartis – to develop closed pump systems that allow nasally-delivered drugs to be formulated without preservatives.
Also being introduced is a next generation nasal pump called Equadel, which has precisely metered sprays delivered every time. This will be very helpful for those drugs that have narrow therapeutic windows, but would benefit from nasal delivery.
