General description

2-Hydroxypropyl-β-cyclodextrin is a cyclic oligosaccharide and used as a pharmaceutical excipient to improve the stability and bioavailability of drugs.

(2-Hydroxypropyl)-β-cyclodextrin, a hydroxyalkyl derivative, is mainly used as a formulation vehicle to increase the dissolution of drugs in water for the successful delivery of medicinal agents to biological systems. It is commonly utilized as a substitute for α-, β- and γ-cyclodextrins.

Application

(2-Hydroxypropyl)-β-cyclodextrin may be used:

As an analytical standard for the determination of the analyte in pharmaceutical formulations as well as nanoparticle formulations by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC), respectively.
To study the host-guest interaction with organic low molecular mass compounds prior to their quantification using reversed phase HPLC technique.
As a mobile phase additive for the effective separation of β-carbolines by HPLC.
In cyclodextrin-modified micellar electrokinetic chromatography (CD-modified MEKC) for the determination of sertraline hydrochloride and the synthesis-related products.
As a chiral selector to resolve pantothenic acid by capillary electrophoresis.

The solubility of lipophilic drugs increases linearly with the concentration of hydroxypropyl-β-cyclodextrin (HBC) in aqueous solution because of the complex between HBC and the drug. This guest-host type complex is formed between the drug and the non-polar cavity in the HBC that results in enhanced solubility. Solutions may be lyophilized to produce freely soluble powders. Non-toxic in rabbits and mice.
