ADVERSE REACTIONS
Maximum urinary flow rate (Qmax), an objective measure of urine flow, was assessed as a secondary efficacy endpoint in Study J and as a safety endpoint in Study K. The results for BPH patients with moderate to severe symptoms and a mean age of 63.2 years (range 44 to 87) who received either CIALIS 5 mg for once daily use or placebo (N=748) in Studies J and K are shown in Table 19 and Figures 5 and 6, respectively. In each of these 2 trials, CIALIS 5 mg for once daily use resulted in statistically significant improvement in the total IPSS compared to placebo. Mean total IPSS showed a decrease starting at the first scheduled observation (4 weeks) in Study K and remained decreased through 12 weeks.

“See FDA-approved patient labeling (Patient Information)” Physicians should discuss with patients the contraindication of CIALIS with regular and/or intermittent use of organic nitrates. Patients should be counseled that concomitant use of CIALIS with nitrates could cause blood pressure to suddenly drop to an unsafe level, resulting in dizziness, syncope, or even heart attack or stroke. Therefore, patients who experience anginal chest pain after taking CIALIS should seek immediate medical attention [see Contraindications (4.1) and Warnings and Precautions (5.1)]. Physicians should discuss with patients the contraindication of CIALIS with any use of a GC stimulator, such as riociguat, for pulmonary arterial hypertension. Patients should be counseled that the concomitant use of CIALIS with GC stimulators may cause blood pressure to drop to an unsafe level.
6.2 Postmarketing Experience
Physicians should consider the potential cardiac risk of sexual activity in patients with preexisting cardiovascular disease. Physicians should advise patients who experience symptoms upon canadian generic cialis pharmacy initiation of sexual activity to refrain from further sexual activity and seek immediate medical attention [see Warnings and Precautions (5.1)]. Physicians should discuss with patients the potential for CIALIS to augment the blood-pressure-lowering effect of alpha-blockers, and antihypertensive medications [see Warnings and Precautions (5.6), Drug Interactions (7.1), and Clinical Pharmacology (12.2)]. Physicians should discuss with patients the clinical implications of continuous exposure to tadalafil when prescribing CIALIS for once daily use, especially the potential for interactions with medications (e.g., nitrates, alpha-blockers, antihypertensives and potent inhibitors of cytochrome P450 3A4) and with substantial consumption of alcohol. [see Dosage and Administration (2.7), Warnings and Precautions (5.6), Drug Interactions (7.1, 7.2), Clinical Pharmacology (12.2), and Clinical Studies (14.2)].
7.3 Potential for CIALIS to Affect Other Drugs
Physicians should advise patients who have an erection lasting greater than 4 hours, whether painful or not, to seek emergency medical attention. Physicians should advise patients to stop use of all PDE5 inhibitors, including CIALIS, and seek medical attention in the event of a sudden loss of vision in one or both eyes. Such an event may be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision, including possible permanent loss of vision, that has been reported rarely postmarketing in temporal association with the use of all PDE5 inhibitors. Physicians should discuss with patients the increased risk of NAION in individuals who have already experienced NAION in one eye. Physicians should also discuss with patients the increased risk of NAION among the general population in patients with a "crowded" optic disc, although evidence is insufficient to support screening of prospective users of PDE5 inhibitors, including CIALIS, for this uncommon condition [see Warnings and Precautions (5.4) and Adverse Reactions (6.2)]. In Study J, the effect of CIALIS 5 mg once daily on maximum urinary flow rate (Qmax) was evaluated as a secondary efficacy endpoint. Mean Qmax increased from baseline in both the treatment and placebo groups (CIALIS 5 mg: 1.6 mL/sec, placebo: 1.2 mL/sec); however, these changes were not significantly different between groups. In Study K, the effect of CIALIS 5 mg once daily on Qmax was evaluated as a safety endpoint.

Mean Qmax increased from baseline in both the treatment and placebo groups (CIALIS 5 mg: 1.6 mL/sec, placebo: 1.1 mL/sec); however, these changes were not significantly different between groups. Efficacy Results in Patients with BPH initiating CIALIS and Finasteride – CIALIS for once daily use initiated together with finasteride was shown to be effective in treating the signs and symptoms of BPH in men with an enlarged prostate (>30 cc) for up to 26 weeks. This additional double-blinded, parallel-design study of 26 weeks duration randomized 696 men to initiate either CIALIS 5 mg with finasteride 5 mg or placebo with finasteride 5 mg. The study population had a mean age of 64 years (range 46-86). Patients with multiple co-morbid conditions such as erectile dysfunction, diabetes mellitus, hypertension, and other cardiovascular disease were included. CIALIS with finasteride demonstrated statistically significant improvement in the signs and symptoms of BPH compared to placebo with finasteride, as measured by the total IPSS at 12 weeks, the primary study endpoint (see Table 20). Key secondary endpoints demonstrated improvement in total white cialis pill IPSS starting at the first scheduled observation at week 4 (CIALIS -4.0, placebo -2.3: p<.001) and the score remained decreased through 26 weeks (CIALIS -5.5, placebo -4.5; p=.022). However, the magnitude of the treatment difference between placebo/finasteride and CIALIS/finasteride decreased from 1.7 points at Week 4 to 1.0 point at Week 26, as shown in Table 20 and in Figure 7. The incremental benefit of CIALIS beyond 26 weeks is unknown.

Figure 7: Mean Total IPSS Changes By Visit in BPH Patients Taking CIALIS for Once Daily Use Together With Finasteride In the 404 patients who had both ED and BPH at baseline, changes in erectile function were assessed as key secondary endpoints using the EF domain of the IIEF questionnaire.
