Mode of Action

Solubility

Marinosolv is suitable for dissolving hardly soluble compounds of different classes.

The technology enables novel stable formulations in a micellar solution of practically insoluble compounds such as corticosteroids or immunosuppressants.

Marinosolv is based on plant derived saponins (glycyrrhizin from liquorice root and escin from horse chestnut).

Bioavailability

Increase of bioavailability in the target tissue.

Faster onset of action compared to suspensions due to higher bioavailability.

In currently marketed products, exemplified by intranasal steroids, an excess of compound is applied compared to the dissolved proportion of the active pharmaceutical ingredient (API), thus, a reduction of the total dose may be possible.

With suspensions, improper dosing may occur because patients often forget to shake the product.

Preservative-free

Aseptic production with filtration may be possible and preservatives may be omitted.

Combination with other active pharmaceutical ingredients (API) may be easier to achieve.

Potential for cost of goods (COGS) reduction based on cheaper production processes.

Patent protection may be achieved for Marinosolv® based formulations with compounds that are off-patent otherwise.

New applications for highly insoluble substances in eyes, lungs, other mucosal tissues, or elsewhere are feasible which may result in low systemic availability and high local activity.
