Sinol has been available in the US since 2004. In 2009 a second generation product, Sinol-M will be launched. Sinol-M is identical to the original formula but also contains MucoAd MucoAd™ is a patented non-toxic, non-irritating, liquid polymer mucoadhesive carrier that prolongs the contact time between drug and mucosa, thus increasing bioavailability. It can be loaded with nearly any pharmaceutical preparation and delivered a variety of mucosal tissues. Reduced mucociliary clearance of intranasally-applied drugs is desirable to reduce the naturally-occurring washing out of topically applied medications.
