View content license ↗ Pharmacokinetics生物半衰期生物半衰期(消除半衰期、药理学半衰期)是生物物质(例如药物)的浓度从其最大初始浓度(Cmax)降低到血浆中Cmax一半所需的时间。它用缩写 t 1 2 {\displaystyle t_{\frac {1}{2}}} 表示。在多室药代动力学中,通常区分两个操作半衰期:早期分布(α)半衰期由从中央室到外周室的重新分配控制,后期消除(β)半衰期由代谢清除和排泄控制。它用于测量代谢物、药物和信号分子等物质从体内的清除情况。
Biological half-life (elimination half-life, pharmacological half-life) is the time taken for the concentration of a biological substance, such as a medication, to decrease from its maximum initial concentration (Cmax) to the half of Cmax in the blood plasma. It is denoted by the abbreviation t 1 2 {\displaystyle t_{\frac {1}{2}}} . In multi-compartment pharmacokinetics, two operational half-lives are often distinguished: an early distribution (α) half-life governed by redistribution from the central to peripheral compartments, and a later elimination (β) half-life governed by metabolic clearance and excretion. This is used to measure the removal of things such as metabolites, drugs, and signalling molecules from the body.

View content license ↗ Pharmacokinetics血气分配系数血气分配系数,也称为血气奥斯特瓦尔德系数,是药理学中用来描述吸入全身麻醉药在血液中的溶解度的术语。根据亨利定律,当两个隔室中的分压相等时,血液中的浓度与与血液接触的气体中的浓度之比在足够低的浓度下几乎恒定。分配系数定义为该比率,因此没有单位。血液中麻醉剂的浓度包括未溶解在血浆中的部分和溶解的部分(与血浆蛋白结合)。与空气中相比,吸入麻醉剂在血液中的溶解度越高,它与血液中血浆蛋白的结合就越多,血气分配系数就越高。它与诱导率成反比。
Blood–gas partition coefficient, also known as Ostwald coefficient for blood–gas, is a term used in pharmacology to describe the solubility of inhaled general anesthetics in blood. According to Henry's law, the ratio of the concentration in blood to the concentration in gas that is in contact with that blood, when the partial pressure in both compartments is equal, is nearly constant at sufficiently low concentrations. The partition coefficient is defined as this ratio and, therefore, has no units. The concentration of the anesthetic in blood includes the portion that is undissolved in plasma and the portion that is dissolved (bound to plasma proteins). The more soluble the inhaled anesthetic is in blood compared to in air, the more it binds to plasma proteins in the blood and the higher the blood–gas partition coefficient. It is inversely related to induction rate.

View content license ↗ Pharmacokinetics血脑屏障血脑屏障(BBB)是内皮细胞的高度选择性半透性边界,调节循环系统和中枢神经系统之间溶质和化学物质的转移,从而保护大脑免受血液中有害或不需要的物质的影响。血脑屏障由毛细血管壁的内皮细胞、包裹毛细血管的星形胶质细胞端脚和嵌入毛细血管基底膜的周细胞形成。该系统允许一些小分子通过被动扩散通过,以及对神经功能至关重要的各种营养物质、离子、有机阴离子以及葡萄糖和氨基酸等分子的选择性和主动运输。
The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. The blood–brain barrier is formed by endothelial cells of the capillary wall, astrocyte end-feet ensheathing the capillary, and pericytes embedded in the capillary basement membrane. This system allows the passage of some small molecules by passive diffusion, as well as the selective and active transport of various nutrients, ions, organic anions, and molecules such as glucose and amino acids that are crucial to neural function.

View content license ↗ Pharmacokinetics丸剂(药物)在医学上,推注(来自拉丁文bolus,球)是在特定时间(通常为1-30分钟)内施用离散量的药物、药物或其他化合物,以将其在血液中的浓度提高到有效水平。可以通过注射给予:静脉内、肌内、鞘内、皮下或通过吸入。关于给药途径的文章提供了更多信息,因为前面的 ROA 列表并不详尽。推注剂量的放置取决于全身所需内容物的全身水平。肌肉注射疫苗可以缓慢释放抗原,从而刺激人体的免疫系统,并为产生抗体留出时间。
In medicine, a bolus (from Latin bolus, ball) is the administration of a discrete amount of medication, drug, or other compound within a specific time, generally 1–30 minutes, to raise its concentration in blood to an effective level. The administration can be given by injection: intravenously, intramuscularly, intrathecally, subcutaneously, or by inhalation. The article on routes of administration provides more information, as the preceding list of ROAs is not exhaustive. The placement of the bolus dose depends on the systemic levels of the contents desired throughout the body. An intramuscular injection of vaccines allows for a slow release of the antigen to stimulate the body's immune system and to allow time for developing antibodies.

View content license ↗ Pharmacokinetics隔室(药代动力学)在药代动力学中,隔室是指一定体积的体液,通常是人体的体液,但也包括具有多个器官系统的其他动物的体液。该研究领域的含义不同于解剖区室的概念,解剖区室以筋膜为界,筋膜是包围哺乳动物器官的纤维组织鞘。相反,该概念侧重于广泛类型的流体系统。该分析用于尝试以数学方式描述小分子在具有多个隔室的生物体中的分布。各种多室模型可用于药代动力学和药理学领域,支持药物发现和环境科学的工作。
In pharmacokinetics, a compartment is a defined volume of body fluids, typically of the human body, but also those of other animals with multiple organ systems. The meaning in this area of study is different from the concept of anatomic compartments, which are bounded by fasciae, the sheath of fibrous tissue that enclose mammalian organs. Instead, the concept focuses on broad types of fluidic systems. This analysis is used in attempts to mathematically describe distribution of small molecules throughout organisms with multiple compartments. Various multi-compartment models can be used in the areas of pharmacokinetics and pharmacology, in the support of efforts in drug discovery, and in environmental science.

View content license ↗ Pharmacokinetics上下文相关的半衰期上下文敏感半衰期或上下文敏感半衰期定义为在旨在维持稳定状态(即恒定血浆浓度)的输注停止后,药物的血浆浓度下降一半所需的时间。 “背景”是输注的持续时间。当具有多室药代动力学模型的药物通过静脉输注给予时,它最初会分布到中央室,然后从该室移出到一个或两个外围室。一旦停止输注,药物就会继续移动到外周隔室中,直到达到平衡。此时,药物离开血浆的唯一途径是通过代谢或排泄。
Context-sensitive half-life or context sensitive half-time is defined as the time taken for blood plasma concentration of a drug to decline by one half after an infusion designed to maintain a steady state (i.e. a constant plasma concentration) has been stopped. The "context" is the duration of infusion. When a drug which has a multicompartmental pharmacokinetic model is given by intravenous infusion it initially will distribute to the central compartment and then move out of this compartment into one or two peripheral compartments. Once this infusion is discontinued, drug continues to move into the peripheral compartments until an equilibrium is reached. At this time, the only way drug may leave plasma is by metabolism or excretion.

View content license ↗ Pharmacokinetics分布(药理)药理学中的分布是药代动力学的一个分支,它描述药物从体内一个位置到另一个位置的可逆转移。药物一旦通过吸收或直接给药进入体循环,就必须分布到组织间液和细胞内液中。每个器官或组织可以接受不同剂量的药物,并且药物可以在不同的器官或组织中保留不同的时间。药物在组织之间的分布取决于组织的血管通透性、局部血流量、心输出量和灌注率以及药物结合组织和血浆蛋白的能力及其脂溶性。 pH 分配也起着重要作用。该药物很容易分布在高灌注器官中,如肝脏、心脏和肾脏。
Distribution in pharmacology is a branch of pharmacokinetics which describes the reversible transfer of a drug from one location to another within the body. Once a drug enters into systemic circulation by absorption or direct administration, it must be distributed into interstitial and intracellular fluids. Each organ or tissue can receive different doses of the drug and the drug can remain in the different organs or tissues for a varying amount of time. The distribution of a drug between tissues is dependent on vascular permeability, regional blood flow, cardiac output and perfusion rate of the tissue and the ability of the drug to bind tissue and plasma proteins and its lipid solubility. pH partition plays a major role as well. The drug is easily distributed in highly perfused organs such as the liver, heart and kidney.

View content license ↗ Pharmacokinetics剂型剂型(也称为单位剂量)是以特定形式提供的药品。它们含有活性成分和非活性成分(赋形剂)的混合物,以特定方式配置(例如胶囊壳)并分配到特定剂量。例如,两种产品可能都是阿莫西林,但一种可能是 500 毫克胶囊,而另一种可能是 250 毫克咀嚼片。术语“单位剂量”也可以指不可重复使用的包装,特别是当每种药品单独包装时。然而,FDA 对此进行了区分,将其称为单位剂量“包装”或“分配”。根据上下文,多个(多个)单位剂量可以指包装在一起的多种不同的药品或包含多种药物和/或剂量的单一产品。
Dosage forms (also called unit doses) are pharmaceutical drug products presented in a specific form for use. They contain a mixture of active ingredients and inactive components (excipients), configured in a particular way (such as a capsule shell) and apportioned into a specific dose. For example, two products may both be amoxicillin, but one may come in 500 mg capsules, while another may be in 250 mg chewable tablets. The term unit dose can also refer to non-reusable packaging, particularly when each drug product is individually packaged. However, the FDA differentiates this by referring to it as unit-dose "packaging" or "dispensing". Depending on the context, multi(ple) unit dose may refer to multiple distinct drug products packaged together or a single product containing multiple drugs and/or doses.

View content license ↗ Pharmacokinetics剂量倾卸剂量倾卸是药物代谢的一种现象,环境因素会导致药物过早和过度释放。这会大大增加药物在体内的浓度,从而产生不良反应甚至药物毒性。剂量倾卸最常见于口服并在胃肠道消化的药物。大约在患者服药的同时,他们还可能摄入其他物质,例如脂肪餐或酒精,以增加药物输送。这些物质可能作用于药物胶囊以加速药物释放,或者它们可能刺激身体的吸收表面以增加药物摄取速率。一般来说,制药公司会尽量避免使用具有显着剂量倾卸效应的药物。此类药物容易出现问题,常常被撤出市场。
Dose dumping is a phenomenon of drug metabolism in which environmental factors can cause the premature and exaggerated release of a drug. This can greatly increase the concentration of a drug in the body and thereby produce adverse effects or even drug-induced toxicity. Dose dumping is most commonly seen in drugs taken by mouth and digested in the gastrointestinal tract. Around the same time patients take their medication, they can also ingest other substances like fatty meals or alcohol that increase drug delivery. The substances may act on the drug's capsule to speed up drug release, or they may stimulate the body's absorptive surfaces to increase the rate of drug uptake. In general, drug companies try to avoid drugs with significant dose dumping effects. Such drugs are prone to problems and are often pulled from the market.

View content license ↗ Pharmacokinetics药物作用药物对人体(或任何其他生物体)的作用称为药效学,而人体对药物的反应称为药代动力学。进入个体的药物往往会刺激某些受体、离子通道,作用于酶或转运蛋白。结果,它们导致人体以特定方式做出反应。一旦受体被激活,它们要么直接在身体上触发特定的反应,要么触发体内激素和/或其他内源性药物的释放以刺激特定的反应。药物通过在特定结合位点结合而与受体相互作用。大多数受体由蛋白质组成,因此药物可以与氨基酸相互作用以改变受体蛋白质的构象。
The action of drugs on the human body (or any other organism's body) is called pharmacodynamics, and the body's response to drugs is called pharmacokinetics. The drugs that enter an individual tend to stimulate certain receptors, ion channels, act on enzymes or transport proteins. As a result, they cause the human body to react in a specific way. Once the receptors are activated, they either trigger a particular response directly on the body, or they trigger the release of hormones and/or other endogenous drugs in the body to stimulate a particular response. Drugs interact with receptors by bonding at specific binding sites. Most receptors are made up of proteins, and the drugs can therefore interact with the amino acids to change the conformation of the receptor proteins.

View content license ↗ Pharmacokinetics药物代谢药物代谢是人类和动物通常通过专门的酶系统对药物进行代谢分解。药物代谢代表了异生物质代谢的一个更专门的子集(来自希腊语“xenos”“陌生人”和“与生物有关的”生物),它还涵盖其他外来有机化合物,例如更广泛的生物体(包括微生物、真菌、植物和动物)中的污染物或毒物。这些反应通常起到解毒药物的作用(尽管在某些情况下,药物代谢的中间体可能会引起毒性作用)。药物代谢的研究是药代动力学(PK)的原则之一,因为代谢(M)是LADME(药物在体内转运)的第四阶段,涉及药物的酶促生物转化和非酶促生物转化,从而导致第五阶段排泄(E)。
Drug metabolism is the metabolic breakdown of drugs by humans and animals, usually through specialized enzymatic systems. Drug metabolism represents a more specialized subset of xenobiotic metabolism (from the Greek xenos "stranger" and biotic "related to living beings") which also covers other foreign organic compounds such as pollutants or poisons in wider group of organisms that includes microorganisms, fungi, plants and animals. These reactions often act to detoxify drugs (although in some cases the intermediates in drug metabolism may cause toxic effects). The study of drug metabolism is one of the tenets of pharmacokinetics (PK) as metabolism (M), the fourth stage of LADME (a drug's transit through the body), involves the enzymatic biotransformation and non-enzymatic biotransformation of a drug, thereby leading to the fifth stage, excretion (E).

View content license ↗ Pharmacokinetics消除(药理学)在药理学中,药物的消除或排泄被理解为药物以未改变的形式(未结合的分子)或修饰为代谢物从生物体中消除(即清除和排泄)的许多过程中的任何一种。肾脏是主要的排泄器官,但也存在其他器官,如肝脏、皮肤、肺或腺体结构,如唾液腺和泪腺。这些器官或结构使用特定的途径将药物从体内排出,这些被称为消除途径:药物通过肾小球滤过和主动肾小管分泌从肾脏中排出,遵循与中间代谢产物相同的步骤和机制。因此,经肾小球过滤的药物也经历肾小管被动重吸收的过程。
In pharmacology, the elimination or excretion of a drug is understood to be any one of a number of processes by which a drug is eliminated (that is, cleared and excreted) from an organism either in an unaltered form (unbound molecules) or modified as a metabolite. The kidney is the main excretory organ although others exist such as the liver, the skin, the lungs or glandular structures, such as the salivary glands and the lacrimal glands. These organs or structures use specific routes to expel a drug from the body, these are termed elimination pathways: Drugs are excreted from the kidney by glomerular filtration and by active tubular secretion following the same steps and mechanisms as the products of intermediate metabolism. Therefore, drugs that are filtered by the glomerulus are also subject to the process of passive tubular reabsorption.

An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine). Some drugs are unstable at the pH of gastric acid and need to be protected from degradation. Enteric coating is also an effective method to obtain drug targeting (such as gastro-resistant drugs). Other drugs such as some anthelmintics may need to reach a high concentration in a specific part of the intestine. Enteric coating may also be used during studies as a research tool to determine drug absorption. Enteric-coated medications pertain to the "delayed action" dosage form category.

Enzyme induction is a process in which a molecule (e.g. a drug) induces (i.e. initiates or enhances) the expression of an enzyme. If the molecule induces enzymes that are responsible for its own metabolism, this is called auto-induction (or auto-inhibition if there is inhibition). These processes are particular forms of gene expression regulation. These terms are of particular interest to pharmacology, and more specifically to drug metabolism and drug interactions. They also apply to molecular biology.

Ethnopsychopharmacology is a field of study which examines differences in the responses of different racial and ethnic groups to psychiatric medication. Individuals' state of mental health is correlated to both the function of the brain and environmental factors. This indicates that understanding the correlation between psychological health and cultural associations is key to attempting to understand more about how the brain functions for people of different ethnic and cultural groups. It has been noted that there are "dramatic cross-ethnic and cross-national variations in the dosing practices and side-effect profiles in response to practically all classes of psychotropics."

Some fruit juices and fruits can interact with numerous drugs, in many cases causing adverse effects. The effect is most studied with grapefruit and grapefruit juice, but similar effects have been observed with certain other citrus fruits. One whole grapefruit, or a small glass (200 mL, 6.8 US fl oz) of grapefruit juice, can cause drug overdose toxicity in patients taking felodipine. Fruit consumed three days before the medicine can still have an effect. The relative risks of different types of citrus fruit have not been systematically studied. Affected drugs typically have an auxiliary label saying "Do not take with grapefruit" on the container, and the interaction is elaborated upon in the package insert. People are advised to ask their physician or pharmacist about drug interactions.

Integrated discrete Multiple Organ Culture (IdMOC) is an in vitro, cell culture based experimental model for the study of intercellular communication. In conventional in vitro systems, each cell type is studied in isolation ignoring critical interactions between organs or cell types. IdMOC technology is based on the concept that multiple organs signal or communicate via the systemic circulation (i.e., blood). The IdMOC plate consists of multiple inner wells within a large interconnecting chamber. Multiple cell types are first individually seeded in the inner wells and, when required, are flooded with an overlying medium to facilitate well-to-well communication. Test material can be added to the overlying medium and both media and cells can be analyzed individually.

In cell biology, ion trapping is the build-up of a higher concentration of a chemical across a cell membrane due to the pKa value of the chemical and difference of pH across the cell membrane. This results in basic chemicals accumulating in acidic bodily fluids such as the cytosol, and acidic chemicals accumulating in basic fluids. Many cells have other mechanisms to pump a molecule inside or outside the cell against the concentration gradient, but these processes are active ones, meaning that they require enzymes and consume cellular energy. In contrast, ion trapping does not require any enzyme or energy. It is similar to osmosis in that they both involve the semipermeable nature of the cell membrane. Cells have a more acidic pH inside the cell than outside (gastric mucosal cells being an exception).

Release (Liberation) is the first step in the process by which medication enters the body and liberates the active ingredient that has been administered. The pharmaceutical drug must separate from the vehicle or the excipient that it was mixed with during manufacture. Some authors split the process of liberation into three steps: disintegration, disaggregation and dissolution. A limiting factor in the adsorption of pharmaceutical drugs is the degree to which they are ionized, as cell membranes are relatively impermeable to ionized molecules. The characteristics of a medication's excipient play a fundamental role in creating a suitable environment for the correct absorption of a drug. This can mean that the same dose of a drug in different forms can have different bioequivalence, as they yield different plasma concentrations and therefore have different therapeutic effects.

Lipophilic efficiency (LiPE), sometimes referred to as ligand-lipophilicity efficiency (LLE) is a parameter used in drug design and drug discovery to evaluate the quality of research compounds, linking potency and lipophilicity in an attempt to estimate druglikeness. For a given compound LiPE is defined as the pIC50 (or pEC50) of interest minus the LogP of the compound. In practice, calculated values such as cLogP or calculated LogD are often used instead of the measured LogP or LogD. LiPE is used to compare compounds of different potencies (pIC50s) and lipophilicities (LogP). High potency (high value of pIC50) is a desirable attribute in drug candidates, as it reduces the risk of non-specific, off-target pharmacology at a given concentration. When associated with low clearance, high potency also allows for low total dose, which lowers the risk of idiosyncratic drug reaction.

Magnetic marker monitoring is a method to monitor the passage of an orally applied drug (tablet, capsule, etc.) through the intestinal tract. The dosage form is enriched with a small amount (0.1 – 2 mg) of magnetite (Fe3O4), which then is magnetized by a high-energy magnetic field. After application the path of the dosage form can be monitored with special detectors, which contain superconducting quantum interference devices (SQUIDs). Due to the very low magnetic field of the iron oxide a specially shielded room is necessary in order to eliminate environmental magnetic interference. The method should be able to yield information about why tablets dissolve unequally before or after meals, which may be important for the bioavailability of drugs. A more developed method, Advanced Magnetic Marker Monitoring, uses the magnetic capsule, a segmented capsule held together by magnetic forces.

Microdosing, or micro-dosing, involves the administration of sub-therapeutic doses of drugs to study their effects in humans, aiming to gather preliminary data on safety, pharmacokinetics, and potential therapeutic benefits without producing significant physiological effects. This is called a "Phase 0 study" and is usually conducted before clinical Phase I to predict whether a drug is viable for the next phase of testing. Human microdosing aims to reduce the resources spent on non-viable drugs and the amount of testing done on animals. Less commonly, the term "microdosing" can be used to refer to precise dispensing of small amounts of a drug substance (e.g., a powder API) for a drug product (e.g., a capsule) and, when the drug substance also happens to be liquid, this can potentially overlap with the term microdispensing (see: Psychedelic microdosing, for example).

Open flow microperfusion (OFM) is a sampling method for clinical and preclinical drug development studies and biomarker research. OFM is designed for continuous sampling of analytes from the interstitial fluid (ISF) of various tissues. It provides direct access to the ISF by insertion of a small, minimally invasive, membrane-free probe with macroscopic openings. Thus, the entire biochemical information of the ISF becomes accessible regardless of the analyte's molecular size, protein-binding property or lipophilicity. OFM is capable of sampling lipophilic and hydrophilic compounds, protein bound and unbound drugs, neurotransmitters, peptides and proteins, antibodies, nanoparticles and nanocarriers, enzymes and vesicles. The OFM probes are perfused with a physiological solution (the perfusate) which equilibrates with the ISF of the surrounding tissue.
