Design and Analysis of Bioavailability and Bioequivalence Studies. Shein-Chung Chow , Jen-pei Liu. Includes several new chapters.

Bioavailability and Bioequivalence Studies

A generic drug product T in order to be approved for marketing authorization a bioequivalence trial is required. In the trial the generic product is compared to the innovator product R in terms of the pharmacokinetic parameters AUC and Cmax. The design of the trial is usually a two-period crossover. This design has the limitation that if the statistical analysis reveal significant sequence effect then the bioequivalence results may be biased and their interpretation is difficult. The sequence effect is confounding with the unequal residual effect and with the formulation by period interaction.

If your institution subscribes to this resource, and you don't have a MyAccess Profile, please contact your library's reference desk for information on how to gain access to this resource from off-campus. Please consult the latest official manual style if you have any questions regarding the format accuracy. Define bioavailability, bioequivalence, and drug product performance. Explain why first-pass effect as well as chemical instability of a drug can result in low relative bioavailability. Explain why bioequivalence may be considered as a measure of drug product performance. Describe various methods for measuring bioavailability and the advantages and disadvantages of each. Explain the conditions under which a generic drug product manufacturer may request a waiver biowaiver for performing an in vivo bioequivalence study.

Design and Analysis of Bioavailability and Bioequivalence Studies

In vivo bioavailability studies are performed for new drug to establish essential pharmacokinetic parameters including rate of absorption, extent of absorption, rates of excretion and metabolism and elimination half-life after a single and multiple dose administration. These essential pharmacokinetic parameters are useful in establishing dosage regimens. Bioequivalence used to assess the expected in vivo biological equivalence of two proprietary preparations of drug products. If two drugs are bioequivalent, it means that they are expected to be same for all intents and purposes. In determining bioequivalence between two drugs such as a reference drug or brand and potential to be test drug or marketed generic drug. Plasma is obtained at regular intervals and assayed for parent drug or metabolite concentration to compare the two drugs.

Some submissions may require more specific clarification of requirements. Sponsors are invited to consult with Health Canada. Modified-release products with multiphasic plasma concentration profiles demonstrated to be integral to their therapeutic effect will be subject to standards on the partial area under the concentration versus time curve p AUC , defined over a restricted time interval s after drug administration. These standards will be applied in addition to those normally applied in the assessment of bioequivalence i. AUC and C max.

Guidance Document: Conduct and Analysis of Comparative Bioavailability Studies

Unusual growth in pharma industry has provoked regulatory agencies to establish regulations regarding bioavailability BA and bioequivalence BE studies. Statistical evaluation parameters like Analysis of Variance help for the better interpretation of the data.

Bioavailability is referred to as the extent and rate to which the active drug ingredient or active moiety from the drug product is absorbed and becomes available at the site of drug action.

Нуматака высоко поднял брови. - Позвоните, как только узнаете номер. ГЛАВА 72 В погруженной во тьму шифровалке Сьюзан Флетчер осторожно пробиралась к платформе кабинета Стратмора.

Если бы Сьюзан не была парализована страхом, она бы расхохоталась ему в лицо. Она раскусила эту тактику разделяй и властвуй, тактику отставного морского пехотинца. Солги и столкни лбами своих врагов. - Это чистая правда! - кричал.  - Мы должны позвать людей на помощь. Нам обоим грозит опасность. Сьюзан не верила ни единому его слову.

Тело Грега Хейла растворилось в темноте, и Сьюзан, инстинктивно поджав ноги, прикрылась пиджаком Стратмора. В шифровалке никогда еще не было так тихо, здесь всегда слышался гул генераторов. Теперь все умолкло, так что можно было различить облегченный вздох раненого чудовища - ТРАНСТЕКСТА, постепенно стихающее шипение и посвистывание, сопутствующие медленному охлаждению. Сьюзан закрыла глаза и начала молиться за Дэвида. Ее молитва была проста: она просила Бога защитить любимого человека.

Прошу прощения за беспокойство, доброй вам но… - Espere. Подождите! - Сеньор Ролдан был коммерсантом до мозга костей. А вдруг это клиент. Новый клиент с севера.

 Выпустите меня, или она умрет.

Его комментарий отличался бесстрастностью опытного полевого агента: - Эта съемка сделана из мини-автобуса, припаркованного в пятидесяти метрах от места убийства. Танкадо приближается справа, Халохот - между деревьев слева. - У нас почти не осталось времени, - сказал Фонтейн.

Шум генераторов, расположенных восемью этажами ниже, звучал сегодня в ее ушах необычайно зловеще. Сьюзан не любила бывать в шифровалке в неурочные часы, поскольку в таких случаях неизменно чувствовала себя запертой в клетке с гигантским зверем из научно-фантастического романа. Она ускорила шаги, чтобы побыстрее оказаться в кабинете шефа.
