Features of Avana

Avana is a generic version of Stendra manufactured by Sunrise Remedies.

It is classified as a fourth-generation ED (Erectile Dysfunction) treatment, offering advantages such as rapid onset and minimal dietary influence, making it a highly user-friendly ED medication.

Additionally, Avana provides the same efficacy as the original drug at a lower price, offering excellent cost performance.

Differences from Other ED Treatments

Avanafil, the active ingredient in Avana, is characterized by its rapid onset and fewer side effects compared to other ED medications.

Like Levitra, which is known for its quick action, Avana typically takes effect within 15–30 minutes after ingestion.

Even if taken after intimate moments with a partner, it can still work effectively, offering greater flexibility in usage timing.

In terms of efficacy, Avana is comparable to Viagra and Levitra, while being less affected by diet and having fewer side effects.

Therefore, it is recommended for those who experienced strong side effects with other ED medications or for first-time users.

Effects of Avana

The main ingredient in Avana, avanafil, inhibits the erection-blocking enzyme PDE-5 (phosphodiesterase type 5).

PDE-5 is an enzyme that breaks down cyclic guanosine monophosphate (cGMP), which promotes erections.

When cGMP is broken down, achieving an erection becomes difficult, a condition known as ED (Erectile Dysfunction).

Avanafil works by inhibiting the PDE-5 enzyme, dilating blood vessels around the penis and relaxing smooth muscle tissue in the corpus cavernosum.

Through this mechanism, blood vessels dilate and muscles relax, allowing more blood to flow easily into the penile corpus cavernosum, thereby facilitating an erection.

Duration of Avana

The effects of Avana typically last approximately 3–6 hours.

However, erections occur only with sexual stimulation or arousal, so it does not affect daily life.

Avana is one of the fastest-acting ED medications, with effects starting as early as 15 minutes after ingestion.

Peak blood concentration is reached in about 30 minutes, so it is recommended to take it 15–30 minutes before sexual activity for optimal results.

Clinical Trial Results

Avanafil (50mg, 100mg, 200mg)



Trial results showed that some participants experienced effects within 15 minutes of ingestion, with successful intercourse still possible even 6 hours later. All three doses demonstrated significant improvement.

Comparison of Avana Effects by Dosage

●Test Results for Different Avanafil Doses
※This table can be scrolled.

Avanafil is an ED medication where higher doses yield more pronounced effects.

Clinical trials showed that the 50mg dose improved the IIEF (International Index of Erectile Function) score by 5.4 points, with an intercourse success rate of 27.8%, indicating moderate improvement.

The 100mg dose improved the score by 8.3 points, and the 200mg dose by 9.5 points, with intercourse success rates of 43.4% and 44.2%, respectively, showing significant improvement.

However, the difference between 100mg and 200mg is minimal, so most users may find 100mg sufficient for desired effects.

User Reviews of Avana

Avana has received many positive reviews, with its rapid onset being praised as its greatest appeal.

Many users report "noticeable effects within about 10–20 minutes after ingestion," and its speed is favorably compared to Levitra.

Additionally, reviews such as "almost no side effects" or "only mild headaches" are common, making it a preferable option for those who experienced stronger side effects with Viagra or Levitra.

Regarding erection strength and duration, there are positive comments like "comparable to or even stronger than Viagra."

Since the price is less than half that of Stendra, it is also praised for its cost-effectiveness.

While there are negative reviews such as "no noticeable effects" or "not suitable for a second round," overall, it is regarded as "an ED medication worth trying."

Timing of Administration

Take one tablet with warm or cool water approximately 30 minutes to 1 hour before sexual activity.

The maximum single dose is 200mg, but first-time users of avanafil are recommended to start with 50mg.

It is advisable to try a lower dose initially, observe the effects, and gradually increase to find the optimal dosage for your needs.

Taking the medication on an empty stomach enhances absorption and maximizes efficacy.

Please ensure at least 24 hours between doses.

This prevents excessive intake, reduces physical burden, and maintains stable effectiveness while ensuring safety.

Food Interaction

Although avanafil is less affected by food, it is not entirely immune to interference. Consuming it with fatty drinks like whole milk may create a film in the stomach lining, hindering absorption.

Therefore, it is recommended to take it 30 minutes before meals to ensure effective absorption and minimize food interference.

If taken after meals, allow approximately 2 hours.

Insufficiently digested food may affect drug absorption.

High-fat meals such as grilled or fried foods may require more than 2 hours for digestion, so taking it on an empty stomach is preferable.

You may eat normally after the drug has been absorbed (about 1 hour later).

Alcohol Interaction

Although concurrent alcohol consumption is possible, the vasodilatory effect may accelerate intoxication, so excessive drinking should be avoided.

Contraindications

・Individuals with cardiovascular diseases (heart/vascular disorders) for whom sexual activity is not recommended

・Patients with severe liver dysfunction

・Patients with severe kidney dysfunction or undergoing dialysis

・Individuals with hypotension or uncontrolled hypertension

・Those who have undergone heart surgery within the last 6 months or have a history of stroke/cerebral hemorrhage/myocardial infarction

・Patients with blood disorders such as multiple myeloma, leukemia, or sickle cell anemia

Prohibited Combinations

Prohibited combination drugs refer to medications that are contraindicated with Avanafil (Avana) and must not be taken simultaneously.

・Nitrates and nitric oxide donors
(Nitroglycerin, Amyl nitrite, Isosorbide dinitrate)
Concurrent use may enhance blood pressure-lowering effects.

・Amiodarone hydrochloride
(Ancarone tablets)
Combination may intensify the QT interval prolongation caused by amiodarone.

・CYP3A4 inhibitors
(Antifungals, antibiotics, HIV medications, Telithromycin, Nefazodone, Ketoconazole, Itraconazole, Ritonavir, Saquinavir, Nelfinavir, Atazanavir, Clarithromycin, Telithromycin, etc.)

Precautions for Drug Combinations

Drugs requiring cautious use with Avanafil refer to medications that require special attention when combined.

May lead to excessive absorption of drug components, increasing efficacy and side effect risks.

・CYP3A4 inhibitors/inducers
Ritonavir, Saquinavir, Darunavir

・Antihypertensive drugs
As Avanafil has blood pressure-lowering effects, concurrent use with antihypertensives may cause orthostatic hypotension symptoms such as dizziness or lightheadedness.
