Sildenafil citrate 100 mg starting dose in men with erectile dysfunction in an international, double-blind, placebo-controlled study: effect on the sexual experience and reducing feelings of anxiety about the next intercourse attempt

If you do experience any of the above severe side effects, you should seek urgent medical attention.

Handled correctly, sildenafil citrate is a generally safe and effective way to treat erectile dysfunction. But you should always read the Patient Information Leaflet before taking it.

Other Comments

There are a few potential side effects to be aware of, including headaches, nausea, and dizziness. These are fairly uncommon, but if you are struggling with them you should speak to your clinician. But like any other medication, it needs to be taken exactly as your doctor or pharmacist has instructed. Sildenafil works by allowing your arteries to relax and open, by making more of a chemical called cGMP available. Increasing blood flow through the arteries in the penis means improved erectile function.

Therapies for Erectile Dysfunction

Cells in your arteries normally release nitric oxide, which, via molecular messengers including cGMP, sends instructions to muscle proteins to relax. This causes increased blood flow into your penis, which causes an erection. An enzyme called PDE-5 normally breaks down that cGMP, which reverses that relaxation, allowing your erection to subside. Sildenafil, a PDE-5 inhibitor, helps maintain that erection instead. There are some situations where you should not take sildenafil. To find out more, book a consultation with one of our clinicians.

The prescribing information for sildenafil citrate (VIAGRA, Pfizer, New York, NY, USA) recommends flexible dosing (50 mg initially, adjusted to 100 or 25 mg based on effectiveness and tolerability) in most men with erectile dysfunction (ED).

In many men, however, 100 mg may be the most appropriate initial dose because it would reduce the need for titration and could prevent discouragement and treatment abandonment should 50 mg be insufficient.

• Female sexual arousal disorder is not treated with sildenafil 100 mg.
• The medication is intended for adult male patients only.
• Always obtain sildenafil from reputable pharmacies to avoid counterfeit drugs.

In addition, tolerability was similar, and improvements from baseline in outcomes on validated, ED-specific, patient-reported questionnaires were either similar (erectile function and the percentage of completely hard and fully rigid erections) or greater (emotional well-being and the overall sexual experience).

• People with heart problems should consult a doctor before using sildenafil 100 mg.
• Sildenafil is contraindicated in patients with severe liver or kidney impairment.
• Allergic reactions, though rare, may include rash, itching, or swelling.

The similarity in outcomes is not surprising given that almost 90% of the men in the flexible-dose trial titrated to 100 mg after 2 weeks.

• Keep out of reach of children and pets for safety reasons.

These data suggest prescription of an initial dose of 100 mg for men with ED, except in those for whom it is inappropriate. For most men with erectile dysfunction (ED), the prescribing information for sildenafil citrate (VIAGRA, Pfizer) recommends an initial dose of 50 mg, increased to 100 mg or decreased to 25 mg based on effectiveness and tolerability (flexible dose).1 However, 100 mg sildenafil produced optimal erection hardness (fully hard and rigid) in a substantial proportion of men with ED.2 In addition, in dose-optimization studies3, 4 and at the end of double-blind, placebo-controlled (DBPC) treatment in recent reports of flexible-dose trials,5, 6 100 mg was the dose that was used by most men.

This report assesses erection hardness, erectile function, emotional well-being, satisfaction (disease related and treatment related) and the overall sexual experience in men treated with 100 mg fixed-dose sildenafil and in men treated with flexible-dose sildenafil (50 and 100 mg), using data from two DBPC trials that were similarly designed except for a fixed-dose vs flexible-dose regimen.7, 8 The objective was to assess the efficacy and tolerability of an initial dose of sildenafil 100 mg relative to the flexible-dosage regimen recommended in the prescribing information.

Before Using

The effects of sildenafil last approximately four hours, which means your erectile function is improved for four hours. The effects of sildenafil become evident when you are sexually stimulated or aroused. You should not have an erection for four hours - a prolonged and painful erection (priapism) is a surgical emergency, and you should seek urgent medical attention should this happen. Most people feel the effect of sildenafil in 45 minutes or so. You’ll need to have sexual stimulation or feel sexually aroused to get an erection. One trial was a multinational (Republic of Korea, Russian Federation, Spain and Sweden), parallel-group, randomized (1:1:1) DBPC trial of fixed-dose sildenafil (50 or 100 mg) or placebo administered on demand over an 8-week treatment period.7 The other trial was a multicenter (United States), parallel-group, randomized (1:1) DBPC trial of flexible-dose sildenafil (50 or 100 mg) administered on demand over a 10-week treatment period.8 In both trials, ⩽1 dose of study medication was to be taken per day.

Details of the patients and methods of the two trials have been published previously.7, 8 As described previously,7, 8 several efficacy assessments were conducted, including the Erection Hardness Score (EHS9), the International Index of Erectile Function (IIEF),10 the Self-Esteem And Relationship (SEAR) questionnaire,11, 12, 13 the Sexual Experience Questionnaire (SEX-Q),14 the Quality of Erection Questionnaire,15 the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS)16 and three global efficacy assessment questions.
