Application

(2-Hydroxypropyl)-β-cyclodextrin may be used:
  • As an analytical standard for the determination of the analyte in pharmaceutical formulations by thin layer chromatography (TLC) method.
  • To study the host-guest interaction with organic low molecular mass compounds prior to their quantification using reversed phase-high performance liquid chromatography (RP-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.

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.
The solubility of lipophilic drugs increases linearly with the concentration of hydroxypropyl-β-cyclodextrin (HP-β-CD) in aqueous solution because of the complex between HP-β-CD and the drug. This guest-host type complex is formed between the drug and the non-polar cavity in the HP-β-CD that results in enhanced solubility. HP-β-CD can be used to prepare an inclusion complex with ropivacaine (RVC) to increase the solubility of RVC for efficient drug delivery.

General description

(2-Hydroxypropyl)-β-cyclodextrin, a hydroxyalkyl derivative, finds application as a formulation vehicle that is used to enhance the solubility of the drugs in aqueous solutions for the successful delivery of medical agents to biological systems. It is generally employed as a substitute for α-, β- and γ-cyclodextrins.

The object of this study was to enhance the solubility, dissolution rate, and oral bioavailability of rutin by complexation with 2-hydroxypropyl-beta-cyclodextrin (HP-beta-CyD). The interaction of rutin with cyclodextrins (CyDs) was evaluated by the solubility, and ultraviolet (UV) and circular dichroism
