Легочная гипертензия (ЛГ) – тяжелое и часто быстро прогрессирующее заболевание с фатальным исходом. Эндотелиальная дисфункция при ЛГ сопровождается снижением продукции оксида азота. После рассмотрения механизмов действия и доказательной базы специфической терапии ингибиторами фосфодиэстеразы 5 (иФДЭ-5) и стимуляторами растворимой гуанилатциклазы проводится обзор исследований по переключению с иФДЭ-5 на риоцигуат. Потенциальным преимуществом риоцигуата является независимость от эндогенного оксида азота и других (помимо ФДЭ-5) изоферментов фосфодиэстераз. Благоприятный профиль эффективности силденафила доказан для основных форм легочной артериальной гипертензии, риоцигуата – для основных форм легочной артериальной гипертензии и хронической тромбоэмболической ЛГ. Клиническая эффективность замены иФДЭ-5 на риоцигуат показана в неконтролируемых исследованиях и рандомизированном контролируемом исследовании REPLACE. Возможность оптимизации терапии за счет переключения с иФДЭ-5 на риоцигуат закреплена в российских (класс и уровень доказательности B-3) и евразийских (класс и уровень доказательности IIb-B) клинических рекомендациях, а также в материалах Кельнского консенсуса экспертов. Дополнительным аргументом за переключение в условиях Российской Федерации служит меньшая стоимость по сравнению с комбинированной терапией. Согласно российским и евразийским рекомендациям по ЛГ и российской инструкции по применению риоцигуата его прием следует начинать не ранее чем через 24 ч после отмены силденафила.
Pulmonary hypertension (PH) is a severe and often rapidly progressive disease with fatal outcome. Endothelial dysfunction in PH is associated with decreased nitric oxide production. After reviewing the mechanisms of action and the evidence base for specific therapy with phosphodiesterase 5 inhibitors (PDE-5) and soluble guanylate cyclase stimulators, a reseach review on switching from PDE-5 to riociguat is conducted. A potential advantage of riociguat is its independence from endogenous nitric oxide and from the other (besides PDE-5) isoenzymes of phosphodiesterases. The favorable efficacy profile of sildenafil has been proven for the main forms of pulmonary arterial hypertension, of riociguat – for the main forms of pulmonary arterial hypertension and chronic thromboembolic PH. The clinical efficacy of replacing PDE-5 with riociguat has been demonstrated in uncontrolled trials and in the randomized controlled study REPLACE. The possibility of therapy optimization by switching from IFDE-5 to riociguat is fixed in the Russian (class and level of evidence B-3) and Eurasian (class and level of evidence IIb-B) clinical guidelines, as well as in the materials of the Cologne Expert Consensus. An additional argument for switching is the lower cost as compared to combination therapy in the Russian Federation. According to the Russian and Eurasian guidelines for PH and the Russian instructions for the use of riociguat, the drug should be taken at least 24 hours after sildenafil discontinuation.
