WebPharmacokinetics of Current and Future Drugs for TIVA. ... In pharmacokinetics, one way of notating this sum of exponentials is to say that the plasma concentration over time is: where t is the time since the bolus, C(t) is the drug concentration following a bolus dose, and A, a, B, b, C, and g are parameters of a pharmacokinetic model. Drugs with fast onset and offset times are most useful for balancing adequate hypnosis/analgesia with rapid recovery. The decline in the plasma concentration of most i.v. agents slows … See more Adequacy of TIVA depends on the maintenance of brain propofol and remifentanil concentrations which are clinically appropriate … See more After an i.v. bolus, the plasma concentration of a typical drug follows an exponential decline in three distinct phases (Fig. 1). These observations are explained by distribution of drug between a central … See more A bolus/elimination/transfer (BET) principle is used to approximate a constant plasma level of drug (however, the algorithms in pharmacokinetic pumps use more exacting analytical solutions).
