Development of a Minimal Physiologically-Based Pharmacokinetic Model to Simulate Lung Exposure in Humans Following Oral Administration of Ivermectin for COVID-19 Drug Repurposing.

abstract：:The reaction of chlorthalidone with methanol to give the corresponding methyl ether was investigated. The kinetics are pseudo-first-order in chlorthalidone, but the observed pseudo-first-order rate constants show an unexpected dependence on the initial chlorthalidone concentration, attributable to the presence of trac...
