Descripción

Descripción general

(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.

Aplicación

La solubilidad de los fármacos lipófilos aumenta linealmente con la concentración de hidroxipropil-β-ciclodextrina (HBC) en disolución acuosa debido al complejo entre la HBC y el fármaco. Este complejo tipo huésped-anfitrión se forma entre el fármaco y la cavidad no polar de la HBC que tiene como consecuencia una mayor solubilidad. Las disoluciones pueden liofilizarse para producir polvos libremente solubles. No tóxico en conejos ni ratones.

(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 (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.
