Materials and Methods
This post-marketing, multicenter, randomized, open-label trial studied the long-term safety and efficacy of tadalafil in Chinese men with ED. Two-year daily application of tadalafil 5 mg continually improved sexual performance and patient satisfaction, with favorable safety profile and good compliance/tolerability.
Why Daily Cialis Is Often Used Alongside TRT
By month 24, total exposure time for tadalafil (mean ± standard deviation [s.d.]) was 622.5 ± 215.5 days. The compliance rate was 82.7% during the randomization period and 88.5% during the extension period. Totally, 631 patients had at least one dose of tadalafil. During the 24-month treatment period, 271 (42.9%) cases reported TEAEs, with the most common being viral upper respiratory tract infection (57 [9.0%]), upper respiratory tract infection (28 [4.4%]), and headache (15 [2.4%]), as shown in Table 2. Specifically, 211 (33.4%), 27 (4.3%), and 33 (5.2%) patients had mild, moderate, and severe AEs, respectively.
Tadalafil Maximum Safe Dose and 40mg Risks
TRAEs were reported in 49 (7.8%) patients, with the most common being headache (13 [2.1%]) and dizziness (9 [1.4%]). The incidence rates of cardiovascular TEAEs were 2.5% and 4.0% by months 12 and 24, respectively. Forty-four events occurred in 25 patients, including 28 mild, 9 moderate, and 7 severe cases. SAEs were reported in 32 (5.1%) patients by month 24 and 15 (2.4%) by month 12. Only one SAE (allergic rhinitis) was possibly associated with tadalafil treatment. The current findings suggested regular daily tadalafil as a practical alternative for Chinese men with ED.

A previous study reported an incidence for TEAEs with on-demand tadalafil of 43.7% after a 13.5-month treatment,20 reaching 71.6% at 2 years (12% TEAEs were severe and 6.3% of patients discontinued tadalafil due to AEs).9 For once-daily tadalafil treatment, the incidence rates of TEAEs were 39.6% at 13.5 months,20 53.4% at 1 year,21 and as high as 71.8% at 2 years (6.7% of patients had tadalafil discontinuation due to AEs).21 Previous meta-analyses showed a good tolerability profile for once-daily tadalafil treatment for at least 6 months, with combined incidence of TEAEs ranging from 30.4% to 34.4%.12,22 In this study, TEAEs were reported in 27.3% and 42.9% of patients at 1 year and 2 years posttreatment, respectively, which were mostly mild.
What is Daily Cialis (Tadalafil 5 mg)?
After a 24-month treatment, 463 (96.1%) and 458 (95.0%) of 482 patients with available GAQ data answered “Yes” to Q1 and Q2, respectively (Figure 3). By month 3, the quality of sexual life, cialis pills 20 mg measured by SLQQ, was significantly improved in both the 2.5 mg (43.0% increase in quality of sexual life score, P < 0.001) and 5 mg (46.9% increase in quality of sexual life score, P < 0.001) groups. In the total population, the quality of sexual life score was increased by 45.8% (P < 0.001) at month 3, by 52.2% (P < 0.001) at month 12, and by 55.3% (P < 0.001) at month 24 (Figure 4a). The treatment satisfaction scores assessed by SLQQ (mean ± s.d.) were 57.8 ± 22.7 and 59.8 ± 21.8 in the 2.5 mg and 5 mg groups at month 3, respectively. The treatment satisfaction scores in the total population (mean ± s.d.) were 59.2 ± 22.1 at month 3, 62.4 ± 21.1 at month 12, and 65.9 ± 20.2 at month 24 (Figure 4b). Our phase 4 study with real-world data showed a relatively lower incidence of TEAEs and increased tolerability after long-term tadalafil treatment in Chinese men with ED. Since the most common TEAEs in this study were similar to those previously reported,9,20,21,23 daily use of tadalafil 5 mg for up to 2 years unveiled no additional safety signals in Chinese men with ED.
| Interacting Drug | Effect | Recommended Action |
|---|---|---|
| Nitrates | Severe hypotension | Avoid co-administration |
| CYP3A4 inhibitors | Increased tadalafil levels | Reduce tadalafil dose |
| Alpha-blockers | Potential for low blood pressure | Monitor blood pressure closely |
Taken together, the safety data in this study indicated that long-term daily application of tadalafil 5 mg is well tolerated, not increasing the risk of AEs.
How should this medicine be used?
The severity of TEAEs and whether AEs were related to treatment were assessed. The exploratory endpoint was the quality of sexual life at months 3, 12, and 24, as assessed by the SLQQ,19 which was not reported in the previous interim analysis. The SLQQ consists of 16 items, including 10 examining the quality of sexual life and 6 assessing the degree of satisfaction with treatment. SLQQ scores for the quality of sexual life ranged from −4 to 4 in the original version,19 but from 0 to 8 in this study, which were then multiplied by 12.5 to obtain scores ranging from 0 to 100. SLQQ scores for treatment satisfaction ranged from 1 to 6 in the original version,19 but from 0 to 5 in this study, which were then multiplied by 20 to generate scores ranging from 0 to 100.
Can Cialis be crushed, split, or chewed?
Tadalafil exposure (determined as days from the first treatment dose to the last one) and treatment compliance were also examined. Good compliance was defined as patients taking 70%–100% of the prescribed tadalafil. Adverse events were summarized with preferred terms in the Medical Dictionary for Regulatory Activities (MedDRA) system. Mean changes in IIEF-EF and SLQQ scores from baseline were determined using a mixed-model with repeated measures (MMRM), and the least squares mean (LSM) difference, standard error (s.e. ), and 95% confidence interval (CI) at each time point were assessed. In this study, the mean IIEF-EF score was rapidly increased from 15.4 at baseline to 21.2 at month 1, and further increased to 23.6 at month 12 and to 24.3 at month 24.

The proportion of patients regaining normal erectile function was 27.9% at month 116 and further increased with further treatment (43.7% at month 1216 and 48.0% at month 24). The self-reported GAQ data revealed that a large proportion of patients had improved erectile function and the ability to engage sexual activity. These findings indicated that erectile function improvement could be maintained after 2 years of treatment with tadalafil, corroborating a previous study.21 Spontaneous sexual activity should be feasible for patients with ED who anticipated frequent intercourse.

Patients with responses below expectations or intolerable AEs would discontinue the PDE5 inhibitor or switch to another one.24 Inability to perform scheduled sexual activities during on-demand treatment or an inconvenient dosing regimen may also lead to poor compliance.24 In this study, under regular tadalafil treatment, patients could have a spontaneous, natural sexual life. The incidence of TEAEs was 27.3% in the first 12 months and showed a low increase by 15.6% (from 27.3% to 42.9%) in the next 12 months, with no new safety signals, which supports the long-term application of tadalafil.
1 Introduction
One (0.2%) death occurred after 389 days of tadalafil treatment. The cause of this death was myocardial infarction, whose relationship with tadalafil could not be determined and it was not related to any study procedures. Erectile function, as measured by IIEF-EF score, was significantly improved from baseline to month 18 (LSM change: 8.4, s.e. : 0.22, 95% CI: 8.0–8.8, P < 0.001) and was maintained to month 24 (LSM change: 8.6, s.e. : 0.23, 95% CI: 8.1–9.0, P < 0.001), as shown in Figure 2.
Serious side effects
The number of patients regaining normal erectile function was 223 (44.0%) among the 507 patients who completed the 18-month follow-up, versus 228 (48.0%) among the 475 patients who completed the 24-month follow-up. After 3 months of treatment, 173 (89.6%) patients answered “Yes” to Q1 and 167 (86.5%) answered “Yes” to Q2 among 193 patients with available GAQ data in the 2.5 mg tadalafil group. Of the 392 patients with cialis 20mg lilly available GAQ data in the 5 mg tadalafil group, 375 (95.7%) and 361 (92.1%) answered “Yes” to Q1 and Q2, respectively. The patients who answered “Yes” to Q1 and Q2 in the total population after 3 months of treatment were 548 (93.7%) and 528 (90.3%), respectively. After a 12-month treatment, 523 (97.5%) and 516 (95.9%) of 538 patients answered “Yes” to Q1 and Q2, respectively. The durable efficacy also largely increased the confidence and acceptability of Chinese men with ED after long-term regular use of tadalafil, even for 2 years.
Why is this medication prescribed?
The fixed effects of each follow-up, pooled investigators, baseline score, and the interaction of each follow-up with baseline score were fitted for MMRM. Other endpoints were presented by descriptive statistics. The SAS software was used for data analysis. Two-sided P < 0.05 was considered statistically significant. A total of 635 patients were randomized approximately 1:2 to the 2.5 mg (n = 211) and 5 mg (n = 424) groups.
2.4 Statistical analysis
In the randomization period, 192 (91.0%) patients in the 2.5 mg group and 388 (91.5%) in the 5 mg group completed the 3-month treatment, and all received subsequent tadalafil 5 mg once daily. In the extension period, 475 (74.8%) of the 635 patients completed the 24-month treatment (Figure 1). The reasons for treatment discontinuation during the trial were voluntary patient withdrawal (n = 91, 14.3%), loss to follow-up (n = 29, 4.6%), AEs (n = 10, 1.6%), protocol violation (n = 24, 3.8%), sponsor decision (n = 3, 0.5%), investigator decision (n buy cialis lilly = 2, 0.3%), and death (n=1, 0.2%). The median age of the 635 patients was 43.6 (range: 22.6–69.7) years. Most (75.9%) patients had mild or moderate ED based on IIEF-EF score, and 25.0% had previous ED therapy (Table 1). Even in elderly individuals or patients with diabetes and cardiovascular diseases, tadalafil could be used without unacceptable safety concerns, with possible vascular protection,25 as supported by previous studies.26–29 This may explain the relatively high treatment compliance rate, reaching 88.5% during the extension period, which was numerically higher than 82.5% found in the randomization period and similar to a previous report in Western patients.21 Men with ED might be satisfied with treatment when they regain normal erectile function, have spontaneous sexual activities, obtain pleasure and partner’s satisfaction, etc.30 In this study, once-daily tadalafil treatment almost met all the expectations of men with ED. Rapidly and persistently improved erectile function, improved quality of sexual life (measured by SLQQ), and no need of scheduled sexual activity were the reasons why a high number of men with ED were satisfied with tadalafil once daily during the continuous treatment, corroborating previous studies.31,32 The current results suggested that tadalafil could be regularly used for long-term treatment in clinical practice, and patients complied with this treatment.
