Amneal Pharmaceuticals NY LLC

1 INDICATIONS AND USAGE

Vardenafil hydrochloride tablets are indicated for the treatment of erectile dysfunction.

2 DOSAGE AND ADMINISTRATION

2.1 General Dose Information

For most patients, the recommended starting dose of vardenafil hydrochloride is 10 mg, taken orally, as needed, approximately 60 minutes before sexual activity. The dose may be increased to a maximum recommended dose of 20 mg or decreased to 5 mg based on efficacy and side effects. The maximum recommended dosing frequency is once per day. Sexual stimulation is required for a response to treatment.

2.2 Use with Food

Vardenafil hydrochloride tablets can be taken with or without food.

2.3 Use in Specific Populations

Geriatrics: A starting dose of 5 mg vardenafil hydrochloride tablets should be considered in patients ≥ 65 years of age [see Use in Specific Populations (8.5)].

Hepatic Impairment: For patients with moderate hepatic impairment (Child-Pugh B), a starting dose of 5 mg vardenafil hydrochloride tablets are recommended. The maximum dose in patients with moderate hepatic impairment should not exceed 10 mg.

Do not use vardenafil hydrochloride tablets in patients with severe hepatic impairment (Child-Pugh C) [see Warnings and Precautions (5.8), Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].

Renal Impairment: Do not use vardenafil hydrochloride tablets in patients on renal dialysis [see Warnings and Precautions (5.9), Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].

2.4 Concomitant Medications

Nitrates: Concomitant use with nitrates and nitric oxide donors in any form is contraindicated [see Contraindications (4.1)].

Guanylate Cyclase (GC) Stimulators, such as riociguat: Concomitant use is contraindicated [see Contraindications (4.2)].

CYP3A4 Inhibitors: The dosage of vardenafil hydrochloride tablets may require adjustment in patients receiving potent CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, atazanavir, and clarithromycin as well as in other patients receiving moderate CYP3A4 inhibitors such as erythromycin [see Drug Interactions (7.2)]. For ritonavir, a single dose of 2.5 mg vardenafil hydrochloride tablets should not be exceeded in a 72-hour period. For indinavir, saquinavir, atazanavir, ketoconazole 400 mg daily, itraconazole 400 mg daily, and clarithromycin, a single dose of 2.5 mg vardenafil hydrochloride tablets should not be exceeded in a 24-hour period. For ketoconazole 200 mg daily, itraconazole 200 mg daily, and erythromycin, a single dose of 5 mg vardenafil hydrochloride tablets should not be exceeded in a 24-hour period.

Alpha-Blockers: In those patients who are stable on alpha-blocker therapy, phosphodiesterase type 5 (PDE5) inhibitors should be initiated at the lowest recommended starting dose. Concomitant treatment should be initiated only if the patient is stable on his alpha-blocker therapy. Stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure in patients taking a phosphodiesterase (PDE5) inhibitor including vardenafil. In those patients who are stable on alpha-blocker therapy, vardenafil hydrochloride tablets should be initiated at a dose of 5 mg (2.5 mg when used concomitantly with certain CYP3A4 inhibitors) [see Warnings and Precautions (5.6) and Drug Interactions (7.1)].

A time interval between dosing should be considered when vardenafil hydrochloride tablets are prescribed concomitantly with alpha-blocker therapy [see Clinical Pharmacology (12.2)].

3 DOSAGE FORMS AND STRENGTHS

Vardenafil hydrochloride tablets, 5 mg, 10 mg or 20 mg contain 5 mg, 10 mg or 20 mg of vardenafil equivalent to 5.926 mg, 11.852 mg or 23.704 vardenafil hydrochloride trihydrate respectively which is equivalent to 5.373 mg, 10.746 mg or 21.492 mg of vardenafil hydrochloride respectively.

Vardenafil hydrochloride tablets, 5 mg are supplied as orange, round, film-coated tablet, free from physical defects, debossed with “AC” & “18” on one side and plain on other side.

Vardenafil hydrochloride tablets, 10 mg are supplied as orange, round, film-coated tablet, free from physical defects, debossed with “AC” & “19” on one side and plain on other side.

Vardenafil hydrochloride tablets, 20 mg are supplied as orange, round, film-coated tablet, free from physical defects, debossed with “AC” & “20” on one side and plain on other side.

4 CONTRAINDICATIONS

4.1 Nitrates

Administration of vardenafil hydrochloride with nitrates (either regularly and/or intermittently) and nitric oxide donors is contraindicated [see Clinical Pharmacology (12.2)]. Consistent with the effects of PDE5 inhibition on the nitric oxide/cyclic guanosine monophosphate pathway, PDE5 inhibitors, including vardenafil hydrochloride may potentiate the hypotensive effects of nitrates. A suitable time interval following dosing of vardenafil hydrochloride for the safe administration of nitrates or nitric oxide donors has not been determined.

4.2 Guanylate Cyclase (GC) Stimulators

Do not use vardenafil hydrochloride in patients who are using a GC stimulator, such as riociguat. PDE5 inhibitors, including vardenafil hydrochloride may potentiate the hypotensive effects of GC stimulators.

5 WARNINGS AND PRECAUTIONS

The evaluation of erectile dysfunction should include a medical assessment, a determination of potential underlying causes and the identification of appropriate treatment.

Before prescribing vardenafil hydrochloride, it is important to note the following:

5.1 Cardiovascular Effects

General

Physicians should consider the cardiovascular status of their patients, since there is a degree of cardiac risk associated with sexual activity. Therefore, treatment for erectile dysfunction, including vardenafil hydrochloride, should not be used in men for whom sexual activity is not recommended because of their underlying cardiovascular status.

There are no controlled clinical data on the safety or efficacy of vardenafil in the following patients; and therefore its use is not recommended until further information is available: unstable angina; hypotension (resting systolic blood pressure of <90 mmHg); uncontrolled hypertension (>170/110 mmHg); recent history of stroke, life-threatening arrhythmia, or myocardial infarction (within the last 6 months); severe cardiac failure.

Left Ventricular Outflow Obstruction

Patients with left ventricular outflow obstruction, (for example, aortic stenosis and idiopathic hypertrophic subaortic stenosis) can be sensitive to the action of vasodilators including PDE5 inhibitors.

Blood Pressure Effects

Vardenafil hydrochloride has systemic vasodilatory properties that resulted in transient decreases in supine blood pressure in healthy volunteers (mean maximum decrease of 7 mmHg systolic and 8 mmHg diastolic) [see Clinical Pharmacology (12.2)]. While this normally would be expected to be of little consequence in most patients, prior to prescribing vardenafil hydrochloride, physicians should carefully consider whether their patients with underlying cardiovascular disease could be affected adversely by such vasodilatory effects.

5.2 Potential for Drug Interactions with Potent or Moderate CYP3A4 Inhibitors

Concomitant administration with potent CYP3A4 inhibitors (such as ritonavir, indinavir, ketoconazole) or moderate CYP3A4 inhibitors (such as erythromycin) increases plasma concentrations of vardenafil. Dosage adjustment is necessary when vardenafil hydrochloride is administered with certain CYP3A4 inhibitors [see Dosage and Administration (2.4), Drug Interactions (7.2)].

Long-term safety information is not available on the concomitant administration of vardenafil with HIV protease inhibitors.
