Abstract
1. Coptisine (COP) is the main active ingredient of Coptis chinensis. In Chinese veterinary clinics, Coptis chinensis is commonly used alongside florfenicol to treat intestinal infections. The goal of this study was to investigate the impact of COP co-administration on the pharmacokinetics of florfenicol in rats.2. Male Sprague-Dawley rats were orally administered COP (50 mg/kg BW) or sterile water for 7 consecutive days, followed by a single oral dose of florfenicol (25 mg/kg BW) on the 8th day. Pharmacokinetics of florfenicol were analyzed using non-compartmental methods, while expression levels of cytochrome P450 (CYP) isoforms in the liver and P-glycoprotein (P-gp) in the jejunum were measured using real-time RT-PCR, Western blot and immunohistochemical analyses.3. Co-administration of COP and florfenicol significantly increased AUC(0-∞), MRT(0-∞), and Cmax of florfenicol, while CLz/F was significantly decreased. COP down-regulated the expression of CYP1A2, CYP2C11, and CYP3A1 in the liver, as well as P-gp in the jejunum.4. These findings suggest that co-administration of COP with florfenicol alters the pharmacokinetics of florfenicol in rats. The down-regulation of CYP and P-gp expression may contribute to this effect. Therefore, the co-administration of COP with florfenicol may enhance the prophylactic or therapeutic efficacy of florfenicol in veterinary practice.

Abstract
Borneol is a traditional Chinese medicine. In Chinese veterinary clinics, borneol and its
related compounds are often used in combination with florfenicol to treat respiratory
infections. This study investigated whether the pharmacokinetics of florfenicol in rats
was affected by its concomitant use with borneol. Sprague-Dawley rats were
intragastrically administered borneol (50 mg/kg body weight (BW)) or 0.5%
carboxymethyl-cellulose sodium for 7 consecutive days, and then intragastrically
administered florfenicol (25 mg/kg BW) on the eighth day. Pharmacokinetic studies showed
that borneol significantly decreased the area under the concentration-time curve from zero
to infinity (AUC(0-t)), time to reach peak concentration (Tmax), and
the peak concentration (Cmax) values of florfenicol, whereas the values of mean
residence time from zero to infinity (MRT(0-t)), elimination half-life
(t1/2z), apparent volume of distribution fraction of the dose absorbed (Vz),
and plasma clearance fraction of the dose absorbed (CLz) were increased significantly.
Furthermore, the mRNA expression levels of multidrug resistance 1 (MDR1) and cytochrome
P450 3A1 (CYP3A1) in the jejunum and of CYP1A2 and CYP2C11 in the liver were significantly
upregulated by borneol. In conclusion, borneol decreased absorption, increased clearance,
improved distribution, and increased the mean residence time of florfenicol in rats,
possibly through regulating the mRNA expression levels of drug-metabolizing enzymes and
efflux transporters.
