This formulation has been developed in Marinomed’s laboratories in order to optimize the efficacy of Carragelose® with the addition of a decongestant effect based on increased osmolality. Instead of sodium chloride (NaCl), which also has an osmotic effect, a new formulation is used to retain the activity of Carragelose® against viruses infecting the respiratory tract.

For this product a special IP-protection in addition to the Carragelose® core patents applies and is valid until 2036.

This product in development will combine the virus-blocking effect of Carragelose® with the decongestant effect of the well-known pharmaceutical compound Xylometazoline.
