Abstract: Sildenafil citrate is a drug commonly used to manage erectile dysfunction. It is designated chemically as 1- [[3-(6,7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4,3-d]pyrimidin-5-yl)-4 ethoxyphenyl] sulfonyl]-4-methylpiperazine citrate (C 22 H 30 N 6 O 4 S). It is a highly selective inhibitor of cyclic guanine monophosphate-specific phosphodiesterase type 5. In late March through mid-November 1998, the US Food and Drug Administration (FDA) published a report on 130 confirmed deaths among men (mean age, 64 yea… Show more

“…Both sildenafil and tadalafil are known to affect the body in different ways. The effect of sildenafil has been widely examined in different body systems including respiratory (Goldberg et al, 2011), renal (Lauver et al, 2014), gastrointestinal (Eherer et al, 2002), nervous (Kyratsas et al, 2013) and cardiovascular (Zusman et al, 2000;Shinlapawittayatorn et al, 2005) systems. Haematological studies with sildenafil by Yildiz et al (2011) showed that sildenafil administration at low dose significantly increased the levels of red blood cells (RBC) GSH and lymphocyte count but decreased the levels of MDA in plasma and RBC, blood mean corpuscular volume and eosinophil counts.…”

“…Confirmando a resolutividade desse manejo, um estudo randomizado realizado com 110 homens obesos com idades entre 35 e 55 anos, estimulados a reduzir pelo menos 10% do peso corporal com dieta diária de 1700 calorias e exercícios semanais de até 195min/ semana, demonstrou melhora no escore do IIEF de 13,9 para 17 (classificação: de "DE moderada" para "DE leve a moderada"), com 31% dos homens recuperando a função sexual 27 . Diversos estudos clínicos demonstraram uma taxa de sucesso no uso de Sildenafil entre 70% a 90% 3,72 . A ação do Sildenafil foi demonstrada através de pletismografia peniana, com uma duração da rigidez 60% maior em relação ao placebo 73 .…”

“…A ação do Sildenafil foi demonstrada através de pletismografia peniana, com uma duração da rigidez 60% maior em relação ao placebo 73 . Foi realizado um estudo prospectivo, comparativo, tipo caso-controle, no qual cada paciente era seu próprio controle, com 29 pacientes, com idades entre 32 e 75 anos e com queixa de DE 72,73 . Os pacientes utilizaram três comprimidos de Sildenafil 50mg antes de relações sexuais em casa por 15 dias e um comprimido 1h antes do acompanhamento com os pesquisadores.…”
