Sanofi and Lilly Agree To Pursue Regulatory Approval Of Nonprescription Cialis

Therefore, physicians should inform patients that substantial consumption of alcohol (e.g., 5 units or greater) in combination with CIALIS can increase the potential for orthostatic signs and symptoms, including increase in heart rate, decrease in standing blood pressure, dizziness, and headache [see Clinical Pharmacology (12.2)].5.10 Concomitant Use of Potent Inhibitors of Cytochrome P450 3A4 (CYP3A4)CIALIS is metabolized predominantly by CYP3A4 in the liver. In patients taking potent inhibitors of CYP3A4 and CIALIS for once daily use, the maximum recommended dose is 2.5 mg [see Dosage and Administration (2.7)].5.11 Combination With Other PDE5 Inhibitors or Erectile Dysfunction TherapiesThe safety and efficacy of combinations of CIALIS and other PDE5 inhibitors or treatments for erectile dysfunction have not been studied.

6 ADVERSE REACTIONS 6.1 Clinical Trials ExperienceBecause clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.Tadalafil was administered to over 9000 men during clinical trials worldwide. For CIALIS for use as needed, over 1300 and 1000 subjects were treated for at least 6 months and 1 year, respectively.CIALIS for Use as Needed for EDIn eight primary placebo-controlled clinical studies of 12 weeks duration, mean age was 59 years (range 22 to 88) and the discontinuation rate due to adverse events in patients treated with tadalafil 10 or 20 mg was 3.1%, compared to 1.4% in placebo treated patients.When taken as recommended in the placebo-controlled clinical trials, the following adverse reactions were reported (see Table 1) for CIALIS for use as needed:CIALIS for Once Daily Use for EDIn three placebo-controlled clinical trials of 12 or 24 weeks duration, mean age was 58 years (range 21 to 82) and the discontinuation rate due to adverse events in patients treated with tadalafil was 4.1%, compared to 2.8% in placebo-treated patients.The following adverse reactions were reported (see Table 2) in clinical trials of 12 weeks duration:The following adverse reactions were reported (see Table 3) over 24 weeks treatment duration in one placebo-controlled clinical study:CIALIS for Once Daily Use for BPH and for ED and BPHIn three placebo-controlled clinical trials of 12 weeks duration, two in patients with BPH and one in patients with ED and BPH, the mean age was 63 years (range 44 to 93) and the discontinuation rate due to adverse events in patients treated with tadalafil was 3.6% compared to 1.6% in placebo-treated patients.

The following adverse reactions were reported (see Table 4).Additional, less frequent adverse reactions (<1%) reported in the controlled clinical trials of CIALIS for BPH or ED and BPH included: gastroesophageal reflux disease, upper abdominal pain, nausea, vomiting, arthralgia, and muscle spasm.Back pain or myalgia was reported at incidence rates described in Tables 1 through 4. In studies of CIALIS for once daily use, adverse reactions of back pain and myalgia were generally mild or moderate with a discontinuation rate of <1% across all indications.Across placebo-controlled studies with CIALIS for use as needed for ED, diarrhea was reported more frequently in patients 65 years of age and older who were treated with CIALIS (2.5% of patients) [see Use in Specific Populations (8.5)].Across all studies with any CIALIS dose, reports of changes in color vision were rare (<0.1% of patients).The following section identifies additional, less frequent events (<2%) reported in controlled clinical trials of CIALIS for once daily use or use as needed. Excluded from this list are those events that were minor, those with no plausible relation to drug use, and reports too imprecise to be meaningful:Body as a Whole — asthenia, face edema, fatigue, pain, peripheral edemaCardiovascular — angina pectoris, chest pain, hypotension, myocardial infarction, postural hypotension, palpitations, syncope, tachycardiaDigestive — abnormal liver function tests, dry mouth, dysphagia, esophagitis, gastritis, GGTP increased, loose stools, nausea, upper abdominal pain, vomiting, gastroesophageal reflux disease, hemorrhoidal hemorrhage, rectal hemorrhageMusculoskeletal — arthralgia, neck painNervous — dizziness, hypesthesia, insomnia, paresthesia, somnolence, vertigoRenal and Urinary — renal impairmentRespiratory — dyspnea, epistaxis, pharyngitisSkin and Appendages — pruritus, rash, sweatingOphthalmologic — blurred vision, changes in color vision, conjunctivitis (including conjunctival hyperemia), eye pain, lacrimation increase, swelling of eyelidsOtologic — sudden decrease or loss of hearing, tinnitusUrogenital — erection increased, spontaneous penile erection6.2 Postmarketing ExperienceThe following adverse reactions have been identified during post approval use of CIALIS.

Overdose/Missed Dose

These events have been chosen for inclusion either due to their seriousness, reporting frequency, lack of clear alternative causation, or a combination of these factors.Cardiovascular and Cerebrovascular — Serious cardiovascular events, including myocardial infarction, sudden cardiac death, stroke, chest pain, palpitations, and tachycardia, have been reported postmarketing in temporal association with the use of tadalafil.

It is not possible to determine whether these events are related directly to CIALIS, to sexual activity, to the patient's underlying cardiovascular disease, to a combination of these factors, or to other factors [see Warnings and Precautions (5.1)].Body as a Whole — hypersensitivity reactions including urticaria, Stevens-Johnson syndrome, and exfoliative dermatitisNervous — migraine, seizure and seizure recurrence, transient global amnesiaOphthalmologic — visual field defect, retinal vein occlusion, retinal artery occlusionNon-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported rarely postmarketing in temporal association with the use of PDE5 inhibitors, including CIALIS.

17.5 Potential for Drug Interactions When Taking CIALIS for Once Daily Use

Most, but not all, of these patients had underlying anatomic or vascular risk factors for development of NAION, including but not necessarily limited to: low cup to disc ratio ("crowded disc"), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia, and smoking [see Warnings and Precautions (5.4)].Otologic — Cases of sudden decrease or loss of hearing have been reported postmarketing in temporal association with the use of PDE5 inhibitors, including CIALIS.

Related/similar drugs

[see Dosage and Administration (2.7), Warnings and Precautions (5.6), and Clinical Pharmacology (12.2)].Antihypertensives — PDE5 inhibitors, including tadalafil, are mild systemic vasodilators. [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.2)].Alcohol — Both alcohol and tadalafil, a PDE5 inhibitor, act as mild vasodilators. [see Warnings and Precautions (5.9) and Clinical Pharmacology (12.2)].7.2 Potential for Other Drugs to Affect CIALIS[See Dosage and Administration (2.7) and Warnings and Precautions (5.10)].Antacids — Simultaneous administration of an antacid (magnesium hydroxide/aluminum hydroxide) and tadalafil reduced the apparent rate of absorption of tadalafil without altering exposure (AUC) to tadalafil.H2 Antagonists (e.g. Nizatidine) — An increase in gastric pH resulting from administration of nizatidine had no significant effect on pharmacokinetics.Cytochrome P450 Inhibitors — CIALIS is a substrate of and predominantly metabolized by CYP3A4. Studies have shown that drugs that inhibit CYP3A4 can increase tadalafil exposure.CYP3A4 (e.g., Ketoconazole) — Ketoconazole (400 mg daily), a selective and potent inhibitor of CYP3A4, increased tadalafil 20 mg single-dose exposure (AUC) by 312% and Cmax by 22%, relative to the values for tadalafil 20 mg alone.

2.2 CIALIS for Once Daily Use for Erectile Dysfunction

Ketoconazole (200 mg daily) increased tadalafil 10-mg single-dose exposure (AUC) by 107% and Cmax by 15%, relative to the values for tadalafil 10 mg alone [see Dosage and Administration (2.7)].Although specific interactions have not been studied, other CYP3A4 inhibitors, such as erythromycin, itraconazole, and grapefruit juice, would likely increase tadalafil exposure.HIV Protease inhibitor — Ritonavir (500 mg or 600 mg twice daily at steady state), an inhibitor of CYP3A4, CYP2C9, CYP2C19, and CYP2D6, increased tadalafil 20-mg single-dose exposure (AUC) by 32% with a 30% reduction in Cmax, relative to the values for tadalafil 20 mg alone. Although specific interactions have not been studied, other HIV protease inhibitors would likely increase tadalafil exposure [see Dosage and Administration (2.7)].Cytochrome P450 Inducers — Studies have shown that drugs that induce CYP3A4 can decrease tadalafil exposure.CYP3A4 (e.g., Rifampin) — Rifampin (600 mg daily), a CYP3A4 inducer, reduced tadalafil 10-mg single-dose exposure (AUC) by 88% and Cmax by 46%, relative to the values for tadalafil 10 mg alone.
