Dose Adjustments
Consistent with its known effects on the nitric oxide/cGMP pathway, sildenafil tablets was shown to potentiate the hypotensive effects of nitrates [ see Dosage and Administration (2.3), Contraindications (4.1), Clinical Pharmacology (12.2)]. Use caution when co-administering alpha-blockers with sildenafil tablets because of potential additive blood pressure-lowering effects. When sildenafil tablets is co-administered with an alpha-blocker, patients should be stable on alpha-blocker therapy prior to initiating sildenafil tablets treatment and sildenafil tablets should be initiated at the lowest dose [ see Dosage and Administration (2.3), Warnings and Precautions (5.5), Clinical Pharmacology (12.2)]. When sildenafil tablets 100 mg were co-administered with amlodipine (5 mg or 10 mg) to hypertensive patients, the mean additional reduction on supine blood pressure was 8 mmHg systolic and 7 mmHg diastolic [ see Warnings and Precautions (5.5), Clinical Pharmacology (12.2)]. Co-administration of ritonavir, a strong CYP3A4 inhibitor, greatly increased the systemic exposure of sildenafil (11-fold increase in AUC).

Animal reproduction studies conducted with sildenafil did not show adverse developmental outcomes when administered during organogenesis in rats and rabbits at oral doses up to 16 and 32 times, respectively, the maximum recommended human dose (MRHD) of 100 mg/day on a mg/m 2basis ( see Data).DataAnimal DataNo evidence of teratogenicity, embryotoxicity or fetotoxicity was observed in rats and rabbits which received oral doses up to 200 mg/kg/day during organogenesis. These doses represent, respectively, about 16 and 32 times the MRHD on a mg/m 2basis in a 50 kg subject. In the rat pre- and postnatal development study, the no observed adverse effect dose was 30 mg/kg/day given for 36 days, about 2 times the MRHD on a mg/m2 basis in a 50 kg subject.8.2 LactationSildenafil tablets are not indicated for use in females.Limited data indicate that sildenafil and its active metabolite are present in human milk. There is no information on the effects on the breastfed child, or the effects on milk production.8.4 Pediatric UseSildenafil tablets is not indicated for use in pediatric patients. Safety and effectiveness have not been established in pediatric patients.8.5 Geriatric UseHealthy elderly volunteers (65 years or over) had a reduced clearance of sildenafil resulting in approximately 84% and 107% higher plasma AUC values of sildenafil and its active N- desmethyl metabolite, respectively, compared to those seen in healthy young volunteers (18–45 years) [ see Clinical Pharmacology (12.3)].
Usual Adult Dose for:
Due to age-differences in plasma protein binding, the corresponding increase in the AUC of free (unbound) sildenafil and its active N-desmethyl metabolite were 45% and 57%, respectively [ see Clinical Pharmacology (12.3)].Of the total number of subjects sildenafil 100g in clinical studies of sildenafil, 18% were 65 years and older, while 2% were 75 years and older. No overall differences in safety or efficacy were observed between older (≥ 65 years of age) and younger (< 65 years of age) subjects.However, since higher plasma levels may increase the incidence of adverse reactions, a starting dose of 25 mg should be considered in older subjects due to the higher systemic exposure[ see Dosage and Administration (2.5)8.6 Renal ImpairmentNo dose adjustment is required for mild (CLcr=50–80 mL/min) and moderate (CLcr=30–49 mL/min) renal impairment. In volunteers with severe renal impairment (Clcr<30 mL/min), sildenafil clearance was reduced, resulting in higher plasma exposure of sildenafil (~2 fold), approximately doubling of C maxand AUC. A starting dose of 25 mg should be considered in patients with severe renal impairment [ see Dosage and Administration (2.5)and Clinical Pharmacology (12.3)].8.7 Hepatic buy sildenafil citrate online canada ImpairmentIn volunteers with hepatic impairment (Child-Pugh Class A and B), sildenafil clearance was reduced, resulting in higher plasma exposure of sildenafil (47% for C maxand 85% for AUC).

Urogenital:prolonged erection, priapism [ see Warnings and Precautions (5.2)and Patient Counseling Information (17)], and hematuria. 7 DRUG INTERACTIONS 7.1 NitratesAdministration of sildenafil tablets with nitric oxide donors such as organic nitrates or organic nitrites in any form is contraindicated.
