Treatment b Citrato de sildenafila ou simplesmente sildenafil é um fármaco que é vendido sob os nomes de Viagra (usado no tratamento da disfunção eréctil no homem – impotência sexual) e Revatio (usado no tratamento da hipertensão arterial pulmonar). No caso do viagra, tem a apresentação de um diamante na cor azul niágara. Medicamento pioneiro na moderna terapêutica da disfunção eréctil masculina, foi sintetizado originalmente pelo Laboratório Farmacêutico Pfizer. Seus principais concorrentes no mercado de medicamentos para o tratamento da disfunção erétil são a tadalafila (Cialis), a vardenafila (Levitra, Vivanza) e mais recentemente a avanafila (Spedra, Stendra). A sildenafila é usada principalmente para o tratamento da disfunção erétil. Ao atuar como um inibidor do PDE-5, permite que o GMPc seja mantido mais tempo em circulação (substância responsável pelo relaxamento dos músculos do pénis), o que leva a um maior aporte de sangue e consequentemente à ereção. Assim como para disfunção erétil, o citrato de sildenafila também é eficiente na doença rara chamada hipertensão arterial pulmonar (HAP ou PAH). Each film-coated tablet contains 100 mg Sildenafil (as sildenafil citrate). Excipient with known effect: Each 50 mg film-coated tablet contains 7.3 mg lactose monohydrate. Sildenafil is indicated in adult men with erectile dysfunction, which is the inability to achieve or maintain a penile erection sufficient for satisfactory sexual performance. In order for Sildenafil to be effective, sexual stimulation is required. Use in adults The recommended dose is 50mg taken as needed approximately one hour before sexual activity. Based on efficacy and tolerability, the dose may be increased to 100mg or decreased to 25mg. The maximum recommended dosing frequency is once per day. If Sildenafil is taken with food, the onset of activity may be delayed compared to the fasted state (see Section 5.2). Elderly Dosage adjustments are not required in elderly patients (≥ 65 years old).
