bioavailability的意思是生物利用度。
在药学中，bioavailability是指药物在给定药物剂量下，进入血液循环后被机体吸收并在体内起作用的程度。它反映了药物在体内的吸收情况，是评价药物在体内性能的重要指标。
以下是一篇关于bioavailability的英文范文：
Title: Bioavailability: The Key to Effective Drug Therapy
Bioavailability is a crucial concept in drug therapy, as it directly impacts how effectively a drug is absorbed, distributed in the body, and ultimately exert its therapeutic effect. From the moment a medication is taken, its bioavailability undergoes a series of complex processes that can either enhance or limit its potential to provide relief to patients.
Understanding bioavailability begins with appreciating its various components. These include the rate at which a drug is absorbed into the bloodstream, its distribution throughout the body, and the extent to which the drug is metabolized and excreted by the body. Each of these factors contributes to the overall bioavailability of a drug, and any deviation from optimal conditions can have a significant impact on its therapeutic efficacy.
In some cases, poor bioavailability can lead to suboptimal drug concentrations in the body, resulting in reduced therapeutic effects or even adverse reactions. Conversely, when a drug demonstrates high bioavailability, it means that it is effectively reaching its target tissues and cells, maximizing its potential to provide relief and minimize side effects.
Bioavailability evaluation is therefore an essential component of drug development, and pharmaceutical companies must ensure that their products meet or exceed established bioavailability standards before they can be marketed and used by patients. By understanding the factors that influence bioavailability, healthcare professionals can better individualize treatment plans and ensure that patients receive the most effective medications possible.
bioavailability的意思是药物在生物体内被吸收并转变成药效形式的能力。
关于bioavailability的英文范文如下：
"The bioavailability of drugs is crucial for the effective treatment of diseases. It refers to the proportion of a drug that is absorbed by the body and converted into an effective form. The bioavailability of a drug can vary greatly depending on its formulation, the route of administration, and the patient's individual characteristics."

“bioavailability”的意思是药物或其代谢物通过皮肤、黏膜等生理屏障进入体循环的速率和程度。
bioavailability英文范文最新变化如下：
概念演变：传统的bioavailability强调的是药物从给药部位进入体循环的速度和程度，而现代的bioavailability概念则强调药物与生物体内各部位相互作用的过程，包括药物在胃肠道的吸收、在生物膜上的通透性、与蛋白的结合等。
应用范围：bioavailability通常用于制药行业中药物研发和生产阶段，用于评估药物的实际疗效。
