3.3.1. Schisandra sphenanthera A Schisandra sphenanthera ethanol extract (SchE) is a herbal medicine also referred to as a Wuzhi capsule, or a Wuhzi tablet, which has been used in the traditional Chinese medicine for thousands of years in cases of hepatitis, hepatic and renal insufficiency, menstrual dysfunction, neurosis and others [74,75,76,77]. It is often prescribed in Chinese transplant patients for tacrolimus-induced hepatitis treatment as a liver-protective agent [77,78]. Studies have shown that the co-administration of Wuhzi tablets and tacrolimus may significantly increase tacrolimus blood concentration. Schisantherin A (STA) and schisandrin A (SIA), the main active agents of SchE, inhibit CYP3A4/5 by both reversible inhibition and the permanent loss of enzyme activity through its destruction [76,79]. Other SchE components, schisandrin B and gomisin A, were found to inhibit P-glycoprotein, whereas gomisin C competitively inhibited and irreversibly deactivated CYP3A [78]. Tacrolimus is metabolized by CYP3A isoenzymes and undergoes P-glycoprotein-mediated transport; therefore, an interaction should be expected [4,76,80]. Tacrolimus blood concentrations increased 1.57–4.66-fold following SchE administration [76]. Moreover, parameters, such as the AUC, AUMC and Cmax of tacrolimus, were reported to increase significantly, although in terms of CL/F and V/F a significant decrease was observed [78,81]. The SchE effect on Cmax and AUC in rats was dose-dependent and the maximum mean plasma concentration of tacrolimus was achieved at 450 mg/kg [77]. Interestingly, a higher SchE dose did not result in an increase in tacrolimus concentration. Furthermore, a single SchE dose administration resulted in a higher mean plasma concentration and AUC compared to a multiple SchE dosing [77]. Despite the remarkable increase in the blood AUC of tacrolimus, no significant changes were found in rat tissue concentrations [82]. Moreover, studies on CYP3A5 polymorphism showed that SchE effect was more pronounced in the CYP3A5 expressers compared to the non-expressers [79,81,83]. An increase in tacrolimus concentration was lower, although still significant when combined with a long-term prednisone treatment [84]. Xin et al. reported lower mean creatinine levels and higher mean BUN levels in healthy volunteers after SchE and tacrolimus co-administration [78]. In terms of liver function, ALT and AST levels significantly decreased following 6-month SchE treatment in renal transplant patients receiving tacrolimus [85]. SchE administration in renal transplant recipients not only did not deteriorate graft function but was found to have a protective effect on its survival [81]. Side effects, such as hyperkalaemia or fever, were reported after SchE and tacrolimus co-administration and were accounted for as a result of an increased tacrolimus blood concentration [78,86]. Several population pharmacokinetic models have been developed to support the individualization of tacrolimus dosing for different groups: renal transplant recipients [81,83,85,87,88], liver transplant recipients [89,90], cardiac transplant recipients [91,92], patients with refractory nephrotic syndrome [93,94], membranous nephropathy [95,96], lupus nephritis [97,98] or myasthenia gravis [99]. SchE may significantly increase tacrolimus bioavailability and reduce its therapeutic costs by 40–60%, nevertheless, authors highly recommend blood tacrolimus concentration monitoring while co-administering with SchE [78,79,82,85].
