In Vitro Ampicillin trihydrate (D-(-)-α-Aminobenzylpenicillin trihydrate) inhibits the growth of E. coli of swine origin in a dose-dependent manner. The effective inhibitory concentration of Ampicillin trihydrate is 2.5 uG/mL[1].
In Vivo Ampicillin trihydrate (D-(-)-α-Aminobenzylpenicillin trihydrate) is very effective in alleviating the symptoms of hemorrhagic enteritis in a 11-week old pig[1]. Ampicillin trihydrate produces maximum concentrations in bile twice as high as in serum. The peak concentration of ampicillin after an oral dose is as twice as high in portal blood as in peripheral blood[2]. Ampicillin trihydrate provides neuroprotection against ischemia-reperfusion brain injury. Ampicillin trihydrate reduces the activities of MMPs and increases the expression level of GLT-1. Pretreatment with Ampicillin trihydrate significantly reduces medial hippocampal cell death following global forebrain ischemia[3].
