Блокада ренин-ангиотензиновой системы (РАС) является одним из концептуальных решений в лечении пациентов с сердечно-сосудистой патологией. Показания к назначению относительно нового класса препаратов – сартанов, влияющих на функциональную активность РАС, пересматриваются и расширяются. Сартаны являются блокаторами рецепторов к ангиотензину II с выраженным гипотензивным класс-специфическим эффектом, обусловленным наличием имидазоловой группы в структуре соединений. Тем не менее существуют молекулярные различия между препаратами, что влияет не только на фармакокинетические характеристики, но и модулирует фармакодинамику, обеспечивает дополнительные, независимые от уровня снижения артериального давления органопротективные эффекты препаратов.
Ключевые слова: ренин-ангиотензиновая система, сартаны, блокаторы рецепторов к ангиотензину II, лозартан, эпросартан, валсартан, ирбесартан, кандесартан, телмисартан, олмесартан, азилсартан.
________________________________________________
Renin-angiotensin system (RAS) blockade is one of the conceptual solutions in the treatment of patients with cardiovascular diseases. Indications for the use of the relatively novel class of drugs sartans that affect the functional activity of RAS are reconsidered and extended. Sartans are angiotensin II receptor blockers with a pronounced antihypertensive class-specific effect caused by the presence of an imidazole group in the structure of the compounds. Nevertheless, there are molecular differences between the drugs, which affects not only their pharmacokinetic characteristics, but also modulates their pharmacodynamics and provides additional organ-protective effects that are independent of the decrease in blood pressure.
