举一反三
- Bioavailability is: A: Amount of drug that reach the systemic circulation B: Drug metabolized in liver before the drug reaches the systemic circulation C: Drug metabolized in liver after the drug reaches the systemic circulation D: Maximum by rectal route
- In<br/>terms of bioavailability, the following statements are true() A: The<br/>amount of a drug absorbed into the bloodstream B: The<br/>total amount of drug in the body at peak concentration C: The<br/>total amount of drug in the body at a steady-state concentration D: The<br/>amount and rate at which a drug is absorbed into the systemic<br/>circulation E: The<br/>amount of drug that passes through the gastrointestinal tract into<br/>the hepatic portal vein
- Absorption is the process of a drug entering systemic circulation from its site of administration. 这里administration的意思是？
- High bioavailability indicates good drug absorption and utilization.
- Drug efficacy refers to A: the range of diseases in which the drug is beneficial B: the maximal intensity of response that can be produced by the drug C: the therapeutic dose range of the drug D: the therapeutic index of the drug E: the minimal intensity of response that can be produced by the drug
