Difference between Sildenafil Tadalafil and Vardenafil
When it comes to treating erectile dysfunction (ED), there are several medications available in the market. Three of the most popular ones are sildenafil, tadalafil, and vardenafil. While they all belong to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors and work by increasing blood flow to the penis, there are some key differences between the three. In this article, we will explore the differences between sildenafil, tadalafil, and vardenafil.
Sildenafil
Sildenafil, sold under the brand name Viagra, was the first medication approved by the Food and Drug Administration (FDA) to treat ED. It is available in doses of 25mg, 50mg, and 100mg and is usually taken 30 minutes to an hour before sexual activity. Sildenafil works by blocking PDE5, which allows for an increase in blood flow to the penis, resulting in an erection.
Effectiveness
Sildenafil has been found to be effective in treating ED in up to 80% of men. It has a rapid onset of action, with effects lasting for up to four hours.
Side Effects
Sildenafil can cause side effects such as headache, facial flushing, indigestion, and nasal congestion. Rare side effects include sudden hearing loss or vision loss.
Tadalafil
Tadalafil, sold under the brand name Cialis, was approved by the FDA to treat ED in 2003. It is available in doses of 2.5mg, 5mg, 10mg, and 20mg and can be taken 30 minutes before sexual activity or as a daily dose. Tadalafil works by blocking PDE5, which increases blood flow to the penis and helps to achieve an erection.
Effectiveness
Tadalafil has been found to be effective in treating ED in up to 80% of men. Its effects last longer than sildenafil, with effects lasting for up to 36 hours.
Side Effects
Tadalafil can cause side effects such as headache, back pain, muscle aches, facial flushing, nasal congestion, and indigestion. Rare side effects include sudden hearing loss or vision loss.
Vardenafil
Vardenafil, sold under the brand name Levitra, was approved by the FDA to treat ED in 2003. It is available in doses of 2.5mg, 5mg, 10mg, and 20mg and is usually taken 30 minutes before sexual activity. Vardenafil works by blocking PDE5, which increases blood flow to the penis and helps to achieve an erection.
Effectiveness
Vardenafil has been found to be effective in treating ED in up to 80% of men. Its effects last longer than sildenafil, with effects lasting for up to five hours.
Side Effects
Vardenafil can cause side effects such as headache, facial flushing, nasal congestion, and indigestion. Rare side effects include sudden hearing loss or vision loss.
Key Differences
While sildenafil, tadalafil, and vardenafil all belong to the same class of drugs and work in similar ways, there are some key differences between them. The main differences are:
- Onset of action: Sildenafil has a rapid onset of action, with effects lasting for up to four hours. Tadalafil has a slower onset of action but longer-lasting effects, with effects lasting for up to 36 hours. Vardenafil has an onset of action similar to sildenafil but with longer-lasting effects than sildenafil, with effects lasting for up to five hours.
- Dosage: Sildenafil is available in doses of 25mg, 50mg, and 100mg. Tadalafil is available in doses of 2.5mg, 5mg, 10mg, and 20mg. Vardenafil is available in doses of 2.5mg, 5mg, 10mg, and 20mg.
- Side effects: While all three medications can cause similar side effects such as headache and facial flushing, vardenafil appears to have a lower incidence of side effects compared to sildenafil and tadalafil.
- Duration of action: Tadalafil has the longest duration of action among the three medications.
