Effects of Botrychium ternatum (Thunb) Sw. On Cytochrome P450 Activities in Rats

Area of Science:

• Pharmacology
• Drug Metabolism
• Herbal Medicine Research

Background:

• Drug interactions frequently arise from cytochrome P450 (CYP) enzyme activity.
• Understanding the influence of traditional medicines on CYP enzymes is crucial for safe co-administration.

Purpose of the Study:

• To investigate the effects of Botrychium Ternatum (BT), a Chinese herbal medicine, on the activity and expression of six key CYP enzymes.
• To assess the impact of BT on liver function and drug metabolism in rats.

Main Methods:

• Twelve healthy male Sprague-Dawley rats were divided into control and BT-treated groups.
• Probe drugs were administered, and plasma concentrations were analyzed using UPLC-MS/MS.
• Enzyme expression levels were quantified via real-time fluorescence quantitative PCR, and serum biochemical indicators were assessed.

Main Results:

• BT administration led to lower area under the curve (AUC) and higher clearance rates for probe drugs.
• BT significantly upregulated the expression of the six studied CYP enzymes.
• BT treatment decreased aspartate aminotransferase levels, indicating a potential protective effect on hepatocytes.

Conclusions:

• Botrychium Ternatum (BT) enhances the activity and expression of cytochrome P450 (CYP) enzymes.
• Patients using BT concurrently with drugs metabolized by CYP enzymes may require dosage adjustments.
• Further research into BT's pharmacokinetic interactions is warranted for clinical safety.
