Revatio, Viagra sildenafil dosing, indications.

Revatio PO: 5 mg or 20 mg 3 times daily, administered 4-6 hours apart IV: 2.5-mg or 10-mg bolus 3 times daily if patient is temporarily unable to take PO Recommended PO/IV dose not to be exceeded Adding Revatio to bosentan does not have any beneficial effect on exercise capacity Not to be prescribed to children (1-17 years) for pulmonary arterial hypertension (PAH); this recommendation against use is based on long-term clinical pediatric trial showing that children taking high doses had higher risk of death than children taking low doses and that low doses were not effective in improving exercise ability (see Cautions) Elicits vasodilatory properties, resulting in mild and transient decreases in blood pressure Use with caution in patients with anatomic deformation of penis (eg, angulation, cavernosal fibrosis, or Peyronie disease), conditions potentially predisposing to priapism (eg, sickle cell anemia, multiple myeloma, or leukemia), cardiovascular disease, bleeding disorders, active peptic ulcer disease, liver disease, renal impairment, multidrug antihypertensive regimens, retinitis pigmentosa, concomitant use of CYP3A4 inhibitors Pulmonary vasodilators may significantly worsen cardiovascular status of patients with pulmonary veno-occlusive disease Patient taking alpha blocker should be stabilized before starting phosphodiesterase (PDE)-5 inhibitor, which should be initiated at lowest dose; if patient is already taking optimized dose of PDE-5 inhibitor, alpha blocker should be initated at lowest dose to avoid hypotension Not to be taken with other PDE-5 inhibitors Sudden decrease or loss of hearing, which may be accompanied by tinnitus and dizziness Viagra: Patients should stop sildenafil and seek medical care if a sudden loss of vision occurs in 1 or both eyes, which could be a sign of nonarteritic anterior ischemic optic neuropathy (NAION); use with caution, and only when the anticipated benefits outweigh the risks, in patients with a history of NAION; patients with a ”crowded” optic disc may also be at an increased risk of NAION; advise patients to seek immediate medical attention in the event of a sudden loss of vision Viagra: Potential for cardiac risk with sexual activity in patients with preexisting cardiovascular disease; therefore, treatment for erectile dysfunction generally should not be instituted in men for whom sexual activity is inadvisable because of their underlying cardiovascular status May cause dose-related impairment of color discrimination; use caution in patients with retinitis pigmentosa Evaluate underlying causes of erectile dysfunction or BPH before initiating therapy Revatio: In small, prematurely terminated study of patients with PAH secondary to sickle-cell disease, vaso-occlusive crises requiring hospitalization were more commonly reported by patients who received sildenafil than by those randomized to placebo; effectiveness of sildenafil in PAH secondary to sickle-cell anemia has not been established; the clinical relevance to men treated for erectile dysfunction with sildenafil is not known Revatio: Not for use in children with PAH; increased mortality with increasing doses (hazard ratio 3.5) was observed in randomized, double-blind, placebo-controlled clinical trial of 234 children (1-17 years) with PAH who had mild-to-moderate symptoms at baseline Revatio: Epistaxis occurred in 13% of patients with PAH secondary to connective tissue disease (eg, scleroderma); this effect was not seen in idiopathic PAH; incidence was also higher in those receiving concomitant PO vitamin K antagonist therapy (9%) than in those not receiving such therapy (2%) Limited published data from randomized controlled trials, case-controlled trials, and case series do not report a clear association with sildenafil and major birth defects, miscarriage, or adverse maternal or fetal outcomes when sildenafil is used during pregnancy; there are risks to mother and fetus from untreated pulmonary arterial hypertension Pregnant women with untreated pulmonary arterial hypertension are at risk for heart failure, stroke, preterm delivery, and maternal and fetal death Limited published data from a case report describe presence of sildenafil and its active metabolite in human milk; there is insufficient information about effects of sildenafil on breastfed infant and no information on effects of sildenafil on milk production; limited clinical data during lactation preclude a clear determination of risk of drug to an infant during lactation The above information is provided for general informational and educational purposes only.

Вспомогательные вещества: целлюлоза микрокристаллическая - 62.632 мг, кальция гидрофосфат - 20.878 мг, натрия кроскармеллоза - 6 мг, магния стеарат - 2.4 мг. Силденафил не влиял на сердечный выброс и не ухудшал кровоток в стенозированных коронарных артериях. Состав пленочной оболочки: опадрай белый II OY-LS-28914 (гипромеллоза, титана диоксид, лактозы моногидрат, триацетин) - 3 мг, опадрай прозрачный YS-2-19114-A (гипромеллоза, триацетин) - 0.9 мг. - блистеры из ПВХ/алюминиевой фольги (6) - пачки картонные с контролем первого вскрытия. У некоторых пациентов через 1 ч после приема силденафила в дозе 100 мг с помощью теста Фансворса-Мунселя 100 выявлено легкое и преходящее нарушение способности цветовосприятия (синего/зеленого цветов); через 2 ч после приема препарата эти изменения исчезали. Селективный ингибитор циклогуанозинмонофосфат (ц ГМФ)-специфической ФДЭ5. У пациентов с легочной гипертензией (ЛГ) прием силденафила приводит к расширению сосудов легких и, в меньшей степени, других сосудов. Его активность в отношении ФДЭ5 превосходит активность в отношении других известных изоферментов фосфодиэстеразы: ФДЭ6, участвующей в передаче светового сигнала в сетчатой оболочке глаза - в 10 раз; ФДЭ1 - в 80 раз; ФДЭ2, ФДЭ4, ФДЭ7-ФДЭ11 - более чем в 700 раз. После приема силденафила в дозе 80 мг 3 раза/сут у здоровых мужчин-добровольцев отмечалось максимальное снижение систолического и диастолического АД в положении лежа в среднем на 9.0 мм рт. Считается, что нарушение цветового зрения вызывается ингибированием ФДЭ6, участвующей в процессе передачи света в сетчатой оболочке глаза. Активность силденафила в отношении ФДЭ5 более чем в 4000 раз превосходит его активность в отношении ФДЭ3, ц АМФ-специфической фосфодиэстеразы, участвующей в сокращении сердца. Силденафил не оказывает влияния на остроту зрения, восприятие контрастности, данные электроретинографии, внутриглазное давление или диаметр зрачка. Силденафил вызывает небольшое и преходящее снижение АД, которое в большинстве случаев не сопровождается клиническими симптомами. У пациентов с подтвержденной начальной возрастной дегенерацией макулы силденафил при однократном приеме в дозе 100 мг не вызывал существенных изменений зрительных функций, в частности, остроты зрения, оцениваемой с помощью решетки Амслер, способности различать цвета светофора, оцениваемые методом периметрии Хамфри, и преходящих нарушений зрительных функций, оцениваемых с помощью метода фотостресса. После приема силденафила внутрь в дозе 100 мг максимальное снижение систолического и диастолического АД в положении лежа составило в среднем 8.3 мм рт. Эффективность у взрослых пациентов с ЛГ Исследовали эффективность силденафила у 278 пациентов с первичной ЛГ (63%), ЛГ, ассоциировавшейся с диффузными заболеваниями соединительной ткани (30%), и ЛГ, развившейся после хирургического лечения врожденных пороков сердца (7%). После приема силденафила в дозе 80 мг 3 раза/сут у пациентов с системной артериальной гипертензией систолическое и диастолическое АД снижалось в среднем на 9.4 мм рт. Систолическое давление в легочной артерии снижалось в среднем на 9%.
