Cmin

C_min is a term used in pharmacokinetics that usually refers to the minimum blood plasma concentration that a drug achieves in tested area after the drug has been administrated and prior to the administration of a second dose. C_min is the opposite of C_max, which is the maximum concentration that a drug achieves after dosing. C_min has direct relationships with other minimum concentrations such as the minimum inhibitory concentration (MIC) and is required to be higher than those concentrations to achieve the minimum efficacy.
