KLEPTOSE® HP HPB - Hydroxypropyl betacyclodextrin

Molecular encapsulation | Solubility improvement | Taste masking
Kleptose HP and HPB for pharmaceutical applications: parenteral use, syrup oral suspensions. HPBCD increase water solubility and bioavailability.


Molecular encapsulation with hydroxypropyl betacyclodextrins is an accepted and useful tool for formulators, with many pharmaceutical products containing cyclodextrin complexes on the market.

Cyclodextrins can improve the solubility of poorly soluble compounds and can be used for taste masking of bitter or unpleasant active ingredients.

Roquette has pioneered the industrial development of cyclodextrins with its KLEPTOSE® range of hydroxypropyl betacyclodextrins.
