Sanofi and Lilly Agree To Pursue Regulatory Approval Of Nonprescription Cialis

Inform patients not to take CIALIS with other PDE5 inhibitors, including ADCIRCA.5.12 Effects on BleedingStudies in vitro have demonstrated that tadalafil is a selective inhibitor of PDE5. Although CIALIS has 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 CIALIS offers no protection against sexually transmitted diseases.

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.

2.3 CIALIS for Once Daily Use for Benign Prostatic Hyperplasia

[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. 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.

The reduced exposure of tadalafil with the coadministration of rifampin or other CYP3A4 inducers can be anticipated to decrease the efficacy of CIALIS for once daily use; the magnitude of decreased efficacy is unknown.7.3 Potential for CIALIS to Affect Other DrugsCytochrome P450 Substrates — CIALIS is not expected to cause clinically significant inhibition or induction of the clearance of drugs metabolized by cytochrome P450 (CYP) isoforms.

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.
