Beta Cyclodextrin
Also known as: β-cyclodextrin, cyclodextrin, beta-cyclodextrin, Beta-Cyclodextrin
Overview
Beta-cyclodextrin (β-CD) is a cyclic oligosaccharide made up of seven glucose units, with the chemical composition C42H70O35. It is derived from starch via enzymatic hydrolysis and is commonly sourced from plants like corn and potatoes. β-CD is primarily utilized in pharmaceutical formulations to enhance drug solubility and bioavailability, as well as to act as a carrier in drug delivery systems. In addition to its pharmaceutical applications, it is also employed in the food and cosmetic industries. Characteristically, β-CD features a hydrophobic interior and a hydrophilic exterior, making it effective for encapsulating hydrophobic molecules, such as cholesterol. Research on β-CD has matured significantly, demonstrating high-quality evidence regarding its effectiveness in facilitating drug solubility and delivery.
Benefits
Beta-cyclodextrin significantly enhances the solubility of hydrophobic drugs, directly improving their bioavailability. In particular, β-CD-based formulations have shown efficacy in cardiovascular health, notably aiding in cholesterol management and reducing plaque formation in preclinical studies. Quantifiable outcomes include substantial reductions in cholesterol levels and plaque areas observed in various research contexts. The benefits of β-CD treatment can be observed within weeks, making it a promising option in therapeutic applications targeting atherosclerosis and related conditions. Additionally, evidence suggests it may have anti-inflammatory properties, further contributing to cardiovascular benefits.
How it works
Beta-cyclodextrin operates by forming inclusion complexes with hydrophobic molecules, which enhances their solubility and facilitates targeted delivery within the body. It primarily interacts with the cardiovascular system, where it plays a role in mitigating cholesterol levels and inflammation. By targeting cholesterol and cholesterol crystals, β-CD helps to dissolve these compounds, enabling their removal from the body. While β-CD itself is poorly absorbed, its encapsulation capability significantly increases the bioavailability of the drugs it carries.
Side effects
Beta-cyclodextrin is generally regarded as safe when used orally; however, it may trigger certain side effects, particularly when administered intravenously. Common adverse effects occurring in over 5% of users include diarrhea. Less frequently, ranging from 1-5%, minor biochemical and hematological changes have been observed in animal studies. Rarely (<1%), carcinogenic effects have been documented in rat studies, though these results are not considered applicable to humans. While it can enhance the bioavailability of other drugs, this can also lead to unintended dosage alterations. No specific contraindications are well-documented, but caution is advised with intravenous administration due to potential renal effects. Importantly, no significant adverse effects on embryo-fetal development have been reported.
Dosage
The minimum effective dose of beta-cyclodextrin for supplement use is not well-established, as it is primarily utilized in pharmaceutical formulations rather than as a standalone supplement. Optimal dosages can vary depending on the application, often ranging from milligrams to grams. Similar to this, upper limits or maximum safe doses for supplement use remain undefined. Timing of dosage may be specific to the application or drug in question. Although β-CD has poor absorption, it enhances the absorption of drugs. There are no specific required cofactors for its use.
