Age-related changes in renal function, hepatic metabolism, and tissue perfusion theoretically could influence peptide clearance and distribution, though no studies have systematically examined age effects
Studies have found that berberine attenuates ischemia-reperfusion injury through NF-B nuclear translocation in mice with transient cerebral artery occlusion, however, this neuroprotective effect was more pronounced at the high dose (50 mg/kg) than the low dose (25 mg/kg) (Zhu et al., 2018)
