7.1 Potential for Pharmacodynamic Interactions with Tadalafil Tablets

Based on published literature, the annual incidence of NAION is 2.5-11.8 cases per 100,000 in males aged ≥50. An observational case-crossover study evaluated the risk of NAION when PDE5 inhibitor use, as a class, occurred immediately before NAION onset (within 5 half-lives), compared to PDE5 inhibitor use in a prior time period. Other risk factors for NAION, such as the presence of “crowded” optic disc, may have contributed to the occurrence of NAION in these studies. Neither the rare postmarketing reports, nor the association of PDE5 inhibitor use and NAION in the observational studies, substantiate a causal relationship between PDE5 inhibitor use and NAION [see Adverse Reactions ( 6.2)] . Physicians should consider whether their patients with underlying NAION risk factors could be adversely affected by use of PDE5 inhibitors.

What could be improved

Individuals with “crowded” optic disc are also considered at greater risk for NAION compared to the general population; however, evidence is insufficient to support screening of prospective users of PDE5 inhibitors, including tadalafil tablets, for this uncommon condition. Patients with known hereditary degenerative retinal disorders, including retinitis pigmentosa, were not included in the clinical trials, and use in these patients is not recommended. Physicians should advise patients to stop taking PDE5 inhibitors, including tadalafil tablets, and seek prompt medical attention in the event of sudden decrease or loss of hearing. It is not possible to determine whether these events are related directly to the use of PDE5 inhibitors or to other factors [see Adverse Reactions ( 6.1, 6.2)] . Physicians should discuss with patients the potential for tadalafil tablets to augment the blood-pressure-lowering effect of alpha-blockers and antihypertensive medications [see Drug Interactions ( 7.1) and Clinical Pharmacology ( 12.2)] .

Caution is advised when PDE5 inhibitors are coadministered with alpha-blockers. Consideration should be given to the following: Patients should be stable on alpha-blocker therapy prior to initiating a PDE5 inhibitor. Patients who demonstrate hemodynamic instability on tadalafil online alpha-blocker therapy alone are at increased risk of symptomatic hypotension with concomitant use of PDE5 inhibitors. In those patients who are stable on alpha-blocker therapy, PDE5 inhibitors should be initiated at the lowest recommended dose. In those patients already taking an optimized dose of PDE5 inhibitor, alpha-blocker therapy should be initiated at the lowest dose. standing blood pressure, dizziness, and headache [see Clinical Pharmacology ( 12.2)] .

Tadalafil tablets are metabolized predominantly by CYP3A4 in the liver.

What is tadalafil?

Although tadalafil tablets have not been shown to increase bleeding times in healthy subjects, use in patients with bleeding disorders or significant active peptic ulceration should be based upon a careful risk-benefit assessment and caution.5.13 Counseling Patients About Sexually Transmitted DiseasesThe use of tadalafil tablets offers no protection against sexually transmitted diseases. Counseling patients about the protective measures necessary to guard against sexually transmitted diseases, including Human Immunodeficiency Virus (HIV) should be considered. Evaluation of erectile dysfunction and BPH should include an appropriate medical assessment to identify potential underlying causes, as well as treatment options. Before prescribing tadalafil tablets, it is important to note the following: Physicians should consider the cardiovascular status of their patients, since there is a degree of cardiac risk associated with sexual activity. Patients who experience symptoms upon initiation of sexual activity should be advised to refrain from further sexual activity and seek immediate medical attention.

Other Interactions

Physicians should discuss with patients the appropriate action in the event that they experience anginal chest pain requiring nitroglycerin following intake of tadalafil tablets. [see Contraindications ( 4.1) and Patient Counseling Information ( 17.1)] . Patients with left ventricular outflow obstruction, (e.g., aortic stenosis and idiopathic hypertrophic subaortic stenosis) can be sensitive to the action of vasodilators, including PDE5 inhibitors. The following groups of patients with cardiovascular disease were not included in clinical safety and efficacy trials for tadalafil tablets, and therefore until further information is available, tadalafil tablets are not recommended for the following groups of patients: myocardial infarction within the last 90 days unstable angina or angina occurring during sexual intercourse New York Heart Association Class 2 or greater heart failure in the last 6 months uncontrolled arrhythmias, hypotension (<90/50 mm Hg), or uncontrolled hypertension As with other PDE5 inhibitors, tadalafil has mild systemic vasodilatory properties that may result in transient decreases in blood pressure. Patients with severely impaired autonomic control of blood pressure may be particularly sensitive to the actions of vasodilators, including PDE5 inhibitors.

Missed Dose

Physicians should be aware that tadalafil tablets for once daily use provide continuous plasma tadalafil levels and should consider this when evaluating the potential for interactions with medications (e.g., nitrates, alpha-blockers, anti-hypertensives and potent inhibitors of CYP3A4) and with substantial consumption of alcohol [see Drug Interactions ( 7.1, 7.2, 7.3)] . There have been rare reports of prolonged erections greater than 4 hours and priapism (painful erections greater than 6 hours in duration) for this class of compounds. Patients who have an erection lasting greater than 4 hours, whether painful or not, should seek emergency medical attention. Tadalafil tablets should be used with caution in patients who have conditions that might predispose them to priapism (such as sickle cell anemia, multiple myeloma, or leukemia), or in patients with anatomical deformation of the penis (such as angulation, cavernosal fibrosis, or Peyronie’s disease). Physicians should advise patients to stop use of all phosphodiesterase type 5 (PDE5) inhibitors, including tadalafil tablets, and seek medical attention in the event of a sudden loss of vision in one or both eyes. In patients taking potent inhibitors of CYP3A4 and tadalafil tablets for once daily use, the maximum recommended dose is 2.5 mg [see Dosage and Administration ( 2.7)] .

3 Results

Stepwise increase in alpha-blocker dose may be associated with further lowering of blood pressure when taking a PDE5 inhibitor. Safety of combined use of PDE5 inhibitors and alpha-blockers may be affected by other variables, including intravascular volume depletion and other antihypertensive drugs. [see Dosage and Administration ( 2.7) and Drug Interactions ( 7.1)] . The efficacy of the coadministration of an alpha-blocker and tadalafil tablets for the treatment of BPH has not been adequately studied, and due to the potential vasodilatory effects of combined use resulting in blood pressure lowering, the combination of tadalafil tablets and alpha-blockers is not recommended for the treatment of BPH. [see Dosage and Administration ( 2.7), Drug Interactions ( 7.1), and Clinical Pharmacology ( 12.2.)].

Side effects

Patients on alpha-blocker therapy for BPH should discontinue their alpha-blocker at least one day prior to starting tadalafil tablets for once daily use for the treatment of BPH. Tadalafil tablets should be limited to 5 mg not more than once in every 72 hours in patients with creatinine clearance less than 30 mL/min or end-stage renal disease on hemodialysis. [see Use in Specific Populations ( 8.7)] . Due to increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis, tadalafil tablets for once daily use is not recommended in patients with creatinine clearance less than 30 mL/min [see Use in Specific Populations ( 8.7)] . Due to increased tadalafil exposure (AUC), limited clinical experience, and the lack of ability to influence clearance by dialysis, tadalafil tablets for once daily use is not recommended in patients with creatinine clearance less than 30 mL/min. The safety and efficacy of combinations of tadalafil tablets and other PDE5 inhibitors or treatments for erectile dysfunction have not been studied.

1. How it works

In patients with creatinine clearance 30 – 50 mL/min, start dosing at 2.5 mg once daily, and increase the dose to 5 mg once daily based upon individual response [see Dosage and Administration ( 2.6), Use in Specific Populations ( 8.7), and Clinical Pharmacology ( 12.3)] . In patients with mild or moderate hepatic impairment, the dose of tadalafil tablets should not exceed 10 mg. Because of insufficient information in patients with severe hepatic impairment, use of tadalafil tablets in this group is not recommended [see Use in Specific Populations ( 8.6)] . Tadalafil tablets for once daily use has not been extensively evaluated in patients with mild or moderate hepatic impairment. Because of insufficient information in patients with severe hepatic impairment, use of tadalafil tablets in this group is not recommended [see Use in Specific Populations ( 8.6)] . Inform patients not to take tadalafil tablets with other PDE5 inhibitors, including ADCIRCA ®.
