Detailed Comparison: Viagra vs Spedra Effectiveness
How Viagra and Spedra Work
Both tablet Viagra (sildenafil) and Spedra (avanafil) belong to a class of medications called PDE5 inhibitors. They work by blocking the phosphodiesterase type 5 enzyme, which increases blood flow to the penis when sexually aroused. Neither medication causes automatic erections - sexual stimulation is still required for both to be effective.
Onset Time and Duration
One key difference between these medications is their speed of action. Viagra typically begins working within 30-60 minutes of taking the tablet, while Spedra may start working in as little as 15-30 minutes. This faster onset time can make Spedra more convenient for spontaneous intimacy. Both medications can remain effective for approximately 4-6 hours, though this doesn't mean an erection will last this long.
Food Interactions
Viagra's effectiveness can be significantly delayed by food, particularly fatty meals, which may postpone its onset by an hour or more. Spedra is generally less affected by food consumption, making it more flexible for timing around meals. This can be an important consideration when choosing between the two options.
Effectiveness Rates
Clinical studies show that both medications are highly effective for treating erectile dysfunction. Viagra has been proven effective in approximately 70-80% of men with ED across various studies. Spedra has shown similar effectiveness rates in clinical trials, with success rates typically ranging from 60-80% depending on the underlying cause of ED and individual patient factors.
Dosage Options
Viagra is available in 25mg, 50mg, and 100mg tablets, with 50mg being the standard starting dose. Spedra comes in 50mg, 100mg, and 200mg tablets, also typically starting at 50mg. Both medications should only be taken once in a 24-hour period and require a prescription following consultation with a healthcare provider.
Cost Considerations
When considering tablet Viagra, it's worth noting that generic sildenafil contains the same active ingredient as branded Viagra but is typically available at a significantly lower cost. EverydayMeds offers both branded Viagra and generic sildenafil, allowing patients to choose based on their preference and budget. Spedra, being a newer medication, doesn't yet have a generic equivalent available.
Side Effects Profile
Both medications share similar potential side effects, including headaches, facial flushing, indigestion, and nasal congestion. Some studies suggest that Spedra may have a slightly lower incidence of visual disturbances compared to Viagra, though serious side effects are rare with both medications when used appropriately.
Choosing the Right Treatment
The choice between Viagra and Spedra often depends on individual circumstances and preferences. Men who value faster onset time and flexibility around meals might prefer Spedra, while those seeking a well-established treatment with generic options available might choose Viagra or sildenafil. Both require the same safety considerations and contraindications, particularly regarding nitrate medications and certain heart conditions.
