As a result, PowderJect Systems deliver pharmaceuticals and vaccines without pain or using needles. Currently, there are two leading niche companies developing novel nasal delivery systems. Firstly, West Pharmaceuticals have several strings to their development bow. For example, they recently started US clinical studies evaluating leuprolide in endometriosis and are preparing European registration documents before entering co-development deals. They are also developing nasal morphine that rapidly relieves pain and shows a profile similar to intravenous formulations.
Clinical testing is underway.
The other major niche player Nastech - is also developing an intranasal morphine formulation as well as, among others, apomorphine for sexual dysfunction and scopolamine for motion sickness. Nastech also plan to explore intranasal scopolamine as an anti-emetic in other areas. Finally, in this whistle stop tour, we'll look at inhaled systemic drug delivery. Everyone is familiar with inhaled drug delivery for asthma and anaesthetics. However, inhaled delivery offers an effective way to deliver some systemically active macromolecules, especially proteins and peptides.
