The half life is the time taken for a parameter to fall to 1/4 its original value. B. Partial agonists act at receptor sites to cause maximal pharmacological effect at high doses. C. Diazepam has a high extraction ratio and is thus subject to flow dependent elimination.

WebAfter i.v. administration, the decline in drug concentrations is biphasic and the drug is cleared very efficiently by the liver, so that its elimination is dependent largely on liver blood flow. Although the drug is some 90-95% bound to plasma, hepatic removal is so avid that both bound and free forms are extracted. WebAbstract. The effect of blood flow rates on hepatic elimination of metoprolol (Met) was studied in a recirculating isolated perfused rat liver system with a constant infusion of Met into the reservoir. This design ensures that, at a steady state, the elimination rate of Met is a constant. The results showed that at flow rates of 10, 20, and 30 ...
