Phosphodiesterase type 5 inhibitors, including STENDRA, and alpha-adrenergic blocking agents are both vasodilators with blood pressure-lowering effects. In such circumstances, nitrates should only be administered under close medical supervision with appropriate hemodynamic monitoring [see STENDRA is contraindicated in patients with a known hypersensitivity to any component of the tablet. The concomitant use of STENDRA and CYP inducers is not recommended.Avanafil had no effect on CYP1A1/2, 2A6, 2B6 and 2E1 (ICA single 200 mg dose of STENDRA did not alter the changes in PT or INR induced by warfarin, and did not affect A single STENDRA 200 mg dose increased AUC and Cmax of a single 50 mg dose of desipramine, a CYP2D6 substrate, by 5.7% and 5.2%, respectively.A single STENDRA 200 mg dose increased AUC and Cmax of a single 40 mg dose of omeprazole, a CYP2C19 substrate, given once daily for 8 days by 5.9% and 8.6%, respectively.A single STENDRA 200 mg dose increased AUC by 2.0% and decreased Cmax by 14% of a single 8 mg dose of rosiglitazone, a CYP2C8 substrate.A single STENDRA 200 mg dose did not affect the pharmacokinetics of amlodipine (5 mg daily), a CYP3A4 substrate [see A single oral dose of STENDRA 200 mg did not affect alcohol (0.5 g ethanol/kg) plasma concentrations [see Before prescribing STENDRA, it is important to note the following:There is a potential for cardiac risk during sexual activity in patients with pre-existing The following groups of patients were not included in clinical safety and efficacy trials for STENDRA, and therefore until further information is available, STENDRA is not recommended for the following groups:As with other PDE5 inhibitors STENDRA has systemic vasodilatory properties and may augment the blood pressure-lowering effect of other anti-For patients taking concomitant strong CYP3A4 inhibitors (including ketoconazole, ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir and telithromycin), do not use STENDRA [see For patients taking concomitant moderate CYP3A4 inhibitors (including erythromycin, amprenavir, aprepitant, diltiazem, fluconazole, fosamprenavir, and verapamil), the maximum recommended dose of STENDRA is 50 mg, not to exceed once every 24 hours [see STENDRA should be used with caution in patients with anatomical deformation of the Physicians should advise patients to stop use of all PDE5 inhibitors, including STENDRA and seek medical attention in the event of a sudden loss of vision in one or both eyes. The pharmacokinetics of avanafil in patients with severe hepatic disease has not been studied; do not use STENDRA in such patients [see Single doses up to 800 mg have been given to healthy subjects, and multiple doses up to 300 mg have been given to patients. AUC0-inf decreased by 2.9% and Cmax increased by 2.8% in patients with mild renal impairment, compared to healthy volunteers with normal renal function. STENDRA at doses of 50 mg, 100 mg, and 200 mg demonstrated statistically significant improvement in all 3 primary efficacy variables relative to placebo (see Table 7).STENDRA was evaluated in ED patients (n=390) with type 1 or type 2 diabetes mellitus in a randomized, double-blind, parallel, placebo-controlled fixed dose trial of 3 months in duration. Moderate CYP3A4 inhibitors (e.g., erythromycin, amprenavir, aprepitant, diltiazem, fluconazole, fosamprenavir, and verapamil) would be expected to have similar effects. In a patient who has taken STENDRA, where nitrate administration is deemed medically necessary in a life threatening situation, at least 12 hours should elapse after the last dose of STENDRA before nitrate administration is considered. When vasodilators are taken in combination, blood pressure-lowering effects of each individual compound may be increased. No dose adjustment is necessary for patients with mild to moderate hepatic impairment (Child Pugh Class A or B). Twenty-four hour pharmacokinetics of avanafil on Days 1 and 6 were compared. Nonsteroidal Anti-inflammatory Drugs (NSAIDs) Many nonsteroidal anti-inflammatory drugs (NSAIDs) used to treat inflammation, fever, and pain are available over-the-counter. OTC drugs that you should buy generic. Based on efficacy and tolerability, the dose may be increased to 200 mg taken as early as approximately 15 minutes before sexual activity, or decreased to 50 mg taken approximately 30 minutes before sexual activity. STENDRA was taken as needed at doses of 50 mg, 100 mg, and 200 mg (Study 1) and 100 mg and 200 mg (Study 2 and Study 3). Patients should be counseled regarding the dosing of STENDRA. 83.9% of patients were White, 13.8% were Black, 1.4% Asian, and < 1% Hispanic. When STENDRA (200 mg) is taken with a high fat meal, the rate of absorption is reduced, with a mean delay in Tmax of 1.12 to
In animal reproduction studies conducted in pregnant rats and rabbits, no adverse developmental outcomes were observed with oral administration of avanafil during organogenesis at exposures for total avanafil at approximately 8 and 6 times, respectively, the Maximum Recommended Human Dose (MRHD) of 200 mg based on AUC (see In pregnant rats administered orally at 100, 300, or 1000 mg/kg/day from gestation days 6 to 17, no evidence of teratogenicity, embryotoxicity, or fetotoxicity was observed at up to 300 mg/kg/day.
