Common and Serious Side Effects of Sildenafil Citrate

↑ Richard E.

• Sildenafil molecules work by relaxing smooth muscle tissue.
• This relaxation allows increased blood flow in blood vessels.
• It is less effective without sexual arousal.
• Some common brand names include Viagra, Revatio, and Kamagra.
• Sildenafil's patent expired, leading to numerous generics.
• Generic versions are usually more affordable.
• It’s important to follow prescription instructions strictly.
• Using more than the recommended dose can be dangerous.

Moon, Stefanie D.

• Sildenafil citrate’s patent expiration increased market competition.

2. Upsides

No patient, except for the 1 patient with bluish visual hallucination, discontinued the drug. Similar side-effect profiles were reported in other studies.9,12,15,19 However, such visual changes similar to those of our patient also are reported in the literature of patients administered sildenafil.25 In conclusion, treatment with sildenafil citrate in selected renal transplant recipients with ED is a valid option with an effective response. Although the same metabolic degradation pathway is used for sildenafil as for cyclosporine, no change is required in the initial dose of immunosuppression.

Frequently asked questions

Patients treated with sildenafil had better scores in 4 domains in comparison to the baseline score, but no difference was observed in the sexual desire domain (P = 0.32). On analyzing the outcome of efficacy of sildenafil on the global efficacy question (whether treatment showed an improvement), 26 of 32 patients (81.3%) showed improvement in the sildenafil group, whereas only 6 patients (18.7%) showed improvement with placebo (P ≤ 0.01). On analyzing AUC and maximum concentration (Cmax) of cyclosporine in 5 selected patients, mean AUC and Cmax were not different with and without sildenafil. Mean AUC of cyclosporine was 7,454 ± 1,483 ng/h/mL with sildenafil compared with 7,460 ± 1,480 ng/h/mL without sildenafil. Mean Cmax also was similar: 1,605 ng/mL with sildenafil compared with 1,604 ng/mL without sildenafil.

Warnings for people with certain health conditions

As listed in Table 3, there were no significant differences between biochemical parameters pre– and post–sildenafil treatment. Serum creatinine and blood urea nitrogen levels were not significantly different in the pre–and post–sildenafil treatment period. Five patients developed headache, 2 patients developed rhinorrhea and flushing, and 1 patient each developed generalized body ache and typical bluish visual hallucination with sildenafil, whereas only 2 patients developed headache with placebo. No patient discontinued the drug, except for the 1 patient with visual hallucination. This study shows that sildenafil is safe and effective for the treatment of ED in renal allograft recipients.

Dosage Forms & Strengths

This is the first randomized, placebo-controlled, crossover study to show the efficacy of sildenafil in renal transplant recipients. sildenafil has an efficacy similar to that in other nontransplantation patients with ED.9-11 sildenafil significantly improved erectile function score, although it did not improve desire level and sexual frequency as expected (Table 1) and also reported in other studies.9,19 These results are similar to previous results in patients with diabetes,19 hemodialysis patients,8-11 and renal transplant recipients12-16 with ED. Treatment efficacy assessed through questions 3 (penetration ability) and 4 (maintenance frequency) was significantly better in these renal transplant recipients (P < 0.001), similar to other patients with ED in another study.19 In this study, all IIEF domain scores improved significantly after sildenafil, except for the sexual desire domain, whereas IIEF domain score did not improve after placebo (Table 2). Similar results were reported in patients with ED sildenafil citrate 100 mg with diabetes19 and hemodialysis patients.9 Studies focusing on the use of sildenafil in renal transplant recipients showed a satisfactory response in 60% to 81% of transplant patients with ED.12-16,20 However, in our study, the response rate was 81.3%, on the higher side of the range. Recently, Zhang et al13 also showed a response in 81.5% of patients, similar to our study. (2005) « Exploring the use of Viagra in place of animal and plant potency products in traditional Chinese medicine » Environmental Conservation 32(3):235-238.

What should I know about storage and disposal of this medication?

This higher response rate may be caused by a shorter duration of dialysis therapy (mean, 3 months; range, 1 to 5.5 months) before transplantation in our patients. Prieto Castro et al12 showed a satisfactory response in 60% of transplant recipients, with a mean time on dialysis therapy of 23 months in patients with a satisfactory response, compared with 43 months in patients for whom the drug was not effective. We do not have a maintenance hemodialysis program, and only patients with a renal transplantation prospect are accepted for hemodialysis therapy. The drug is more effective in patients who have less time on dialysis therapy before transplantation because penile vascular disease is less advanced.12 A greater prevalence of ED usually is seen in patients with a longer duration of maintenance hemodialysis.2,3 In a large experience of 22 years of ED in renal transplant recipients, Lasaponara et al16 reported that ED is an important problem in male renal transplant recipients, and cultural resistance to treatment is common. However, sildenafil is an accepted mode of treatment.

More common

They also showed that more renal transplant patients are reporting ED (78%) after 1998, after the invention of sildenafil, compared with 45% before 1998.16 Russo et al14 showed improvement in IIEF domain scores in 20 renal transplant recipients with ED with the use of sildenafil. This study was designed more to show the effect of renal transplantation on ED, rather than the effect of sildenafil.14 Chatterjee et al21 also showed a good response to combined testosterone and sildenafil therapy in all patients, but only 8 of 12 patients were renal transplant recipients and 4 patients were on hemodialysis therapy in this pilot study with a different design. Therefore, the response rate to combined sildenafil and testosterone therapy cannot be compared with the response rate of sildenafil alone in our renal transplant recipients. Sildenafil and cyclosporine are metabolized through cytochrome P-450 isoform 3A4, and there is concern of a drug interaction between the 2 drugs. However, AUC and Cmax were not changed after use of sildenafil, and this may have been caused by highly selective action on phosphodiesterase type 5 and the short half-life (60 to 90 minutes) of sildenafil.

Jet lag research

No change in drug dosing of cyclosporine is required, which was shown in other studies.12-16,20,22 However, only the trough level of cyclosporine was compared in these studies. We are the first to compare the AUC of cyclosporine before and after sildenafil therapy. Blood urea nitrogen and serum creatinine levels were not changed significantly after the use of sildenafil in our study. Similar observations were seen in other studies.12-14 An increase in glomerular filtration rate was seen lovegra sildenafil in kidney transplant recipients after use of sildenafil.23,24 However, a slight increase in serum creatinine levels between the inclusion visit and study end was observed in a study, but there was no evidence of sildenafil citrate tablet a causal relationship between this increase and sildenafil administration in this study.15 In the present study, side effects were reported in both the placebo and sildenafil groups. Headache was the most common side effect. New England Journal of Medicine 353:2148–2157.
