Although numerous protein therapeutics have been approved or are in advanced clinical testing, the development of more sophisticated delivery systems for this rapidly expanding class of therapeutic agents has not kept pace. The short in vivo half-lives, the physical and chemical instability, and the low oral bioavailability of proteins currently necessitate their administration by frequent injections of protein solutions.

The role of microfluidics in protein formulations with pre-programmed functional characteristics

Since the discovery of insulin and its therapeutic application to the treatment of diabetes early in the 20th century, proteins and peptides have held enormous attraction as potential therapeutic agents. Many peptides demonstrate high potency and selectivity while exhibiting essentially no chemical toxicity as they metabolize to naturally occurring amino acids. In spite of the many attractive aspects of peptides and proteins as potential therapeutics, their susceptibility to denaturation and hydrolysis in the gastrointestinal tract has necessitated administration by injection, and this remains their major shortcoming as drugs. As a result, while the range of clinical indications for therapeutic peptides and proteins is substantial, the actual number of such therapeutics in general use today, though growing, is quite small compared with the number of chemically synthesized orally bioavailable small molecule drugs. Literally dozens of excipients have been tested as potential enhancers of transmucosal absorption in the hope that alternate non-invasive means of administering peptides and proteins might be achieved. Some examples are shown in Table 1.

FORMULATING PEPTIDES – Novel Formulations for Non-Invasive Delivery & Stabilization of Peptides

Formulating protein therapeutics into nanoparticles NPs of poly lactic- co -glycolic acid PLGA provides key features such as protection against clearance, sustained release and less side effects by possible attachment of targeting ligands. These NPs also offer the potential for protein combination therapy, which is expected to exploit synergetic bioresponses, avoid multiple dosage regimens and consequent mis-dosing. Since the conventional manufacture of protein-loaded PLGA NPs is still associated with low-throughput, new continuous manufacturing methods such as microfluidics have been established.

Pharmaceutical formulation , in pharmaceutics , is the process in which different chemical substances, including the active drug , are combined to produce a final medicinal product. The word formulation is often used in a way that includes dosage form. Formulation studies involve developing a preparation of the drug which is both stable and acceptable to the patient.

As is the case with other pharmaceuticals, formulation development is one of the critical steps in developing a protein as a therapeutic product. Development of stable protein formulations may require even more resources and effort than conventional small molecule pharmaceuticals. Proteins typically have more stability issues as a result of their complexity and delicate structural stability. Fortunately, a great deal of research regarding protein stability has been conducted and this information is readily available in the literature reviewed by Manning et al. Ultimately, it would be ideal to be able to develop a pure pharmaceutical containing only the native protein.

Improving protein therapeutics with sustained-release formulations

И все же Сьюзан понимала, что остановить Хейла могут только его представления о чести и честности. Она вспомнила об алгоритме Попрыгунчик. Один раз Грег Хейл уже разрушил планы АНБ. Что мешает ему сделать это еще. Но Танкадо… - размышляла .

ТРАНСТЕКСТ еще никогда не сталкивался с шифром, который не мог бы взломать менее чем за один час. Обычно же открытый текст поступал на принтер Стратмора за считанные минуты. Она взглянула на скоростное печатное устройство позади письменного стола шефа. В нем ничего не. - Сьюзан, - тихо сказал Стратмор, - с этим сначала будет трудно свыкнуться, но все же послушай меня хоть минутку.  - Он прикусил губу.

 Не знаю. Все это выглядит довольно странно. - Думаешь, надо вернуть им отчет. Она посмотрела на него недовольно. В том, что касалось Мидж Милкен, существовали две вещи, которые никому не позволялось ставить под сомнение. Первой из них были предоставляемые ею данные.

and production of protein and peptide drug formulations is not well developed and in choosing a formulation for delivery of a therapeutic protein or peptide.

 - У нас приказ. Мы отчитываемся перед директором Лиландом Фонтейном, и только перед. Фонтейна это позабавило. - Вы знаете, кто. - Какая разница? - огрызнулся светловолосый.

Бринкерхофф хотел было уже взять следующий документ, но что-то задержало его внимание. В самом низу страницы отсутствовала последняя СЦР. В ней оказалось такое количество знаков, что ее пришлось перенести в следующую колонку. Увидев эту цифру, Бринкерхофф испытал настоящий шок. 999 999 999.

Ей хотелось поскорее оказаться в Третьем узле, и она достаточно хорошо изучила своего шефа, чтобы знать: Стратмор никуда не уйдет, пока она не разыщет ключ, спрятанный где-то в компьютере Хейла. Ей почти удалось проскользнуть внутрь, и теперь она изо всех сил пыталась удержать стремившиеся захлопнуться створки, но на мгновение выпустила их из рук. Створки стали стремительно сближаться.

Мужчины оглянулись. В дверях стояла Росио Ева Гранада. Это было впечатляющее зрелище.

Из-под колес взметнулся гравий. Мотоцикл начал подниматься по склону. Колеса неистово вращались на рыхлой земле.

Ускоренное проигрывание видеозаписи придавало изображению некоторую комичность. Вот Танкадо вышел на открытое место и залюбовался открывшимся перед ним зрелищем. Он козырьком поднес руку к глазам и стал разглядывать шпили над внушительным фасадом. - Смотрите внимательно, - предупредил Смит.

 - Его столкнул вниз Стратмор. Я все это видел, потому что прятался в подсобке. Чатрукьян хотел вызвать службу безопасности, что разрушило бы все планы Стратмора.
