https://www.selleckchem.com/products/iu1.html This study was aimed to investigate the influence of verapamil-mediated inhibition of P-glycoprotein (P-gp) on the pharmacokinetics of ivermectin (IVM) given orally and subcutaneously (SC) to rabbits. Twenty New Zealand rabbits were allotted to 4 groups (n = 5) and received IVM either orally or SC (0.4 mg/kg) alone or co-administered with verapamil (2 mg/kg SC, 3 times at a 12-hr interval). Plasma, fecal, and urine samples were collected over 30 days after medication to assess IVM concentrations in these samples. No significant differences were observed in the pharmacokinetic parameters of IVM between oral and SC administrations. The area under the plasma concentration-time curve was higher (p less then .05) after IVM (oral)/verapamil treatment, compared with oral IVM alone. Moreover, the time to the Cmax of IVM was shorter (p less then .05), whereas the elimination half-life and the mean residence time were longer (p less then .05) in the presence of verapamil. The IVM/verapamil combination administered orally or SC reduced fecal IVM concentrations, compared with IVM alone. In conclusion, the significant changes by verapamil on the pharmacokinetics of IVM, likely due to the inhibition of a P-gp-mediated intestinal secretion, may change IVM's antinematodal activity. Modern agricultural management approaches are often dependent on the application of chemicals, resulting in adverse impacts on human and environmental health. Therefore, for sustainable agriculture, there is a need to implement integrated agriculture practices that can maintain natural soil microbiome and enhance crop production. Various agricultural approaches influence crop production by impacting the functional bacterial community entailed in biogeochemical cycles, for example, nitrogen (N) cycle. This study aimed to assess the rhizospheric N cycling community of soybean under three agricultural practices, namely, conservation agriculture (CA), conventiona
