The active ingredient is avanafil, a phosphodiesterase-5 (PDE5) inhibitor that enhances blood flow to the penis during sexual stimulation. It is supplied as an oral tablet in strengths of 50 mg, 100 mg, and 200 mg. As a generic product, avanafil offers the same therapeutic benefits as the branded version Stendra while providing a more affordable option for patients. --- ## Quick Reference Facts **Active Ingredient** : Avanafil **Form** : Pill 50 mg | 100 mg | 200 mg **Primary Uses** : Treatment of erectile dysfunction in adult males --- ## What is Avanafil? Avanafil is the generic version of medications containing the active compound avanafil. It belongs to the class of phosphodiesterase-5 inhibitors, which also includes sildenafil, tadalafil, and vardenafil. The drug was first approved by the U.S. Food and Drug Administration (FDA) in 2012 for the oral treatment of erectile dysfunction. While the brand name Stendra is marketed by Vivus, the generic formulation is produced by a variety of certified manufacturers and is widely available in many international markets. As a generic product, avanafil is required by regulatory agencies to demonstrate bioequivalence to the branded reference, ensuring identical safety, efficacy, and quality. --- ## How Avanafil Works Avanafil selectively inhibits the enzyme phosphodiesterase-5 (PDE5) found in the smooth muscle of the penile corpora cavernosa. Under normal sexual stimulation, nitric oxide released from nerve endings activates guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP). Elevated cGMP causes smooth-muscle relaxation, allowing blood to fill the penile tissue and produce an erection. By blocking PDE5, avanafil prevents the breakdown of cGMP, thereby prolonging the vasodilatory response. Key pharmacologic features include: * **Rapid onset:** Clinical trials show an average onset of erection-facilitating effect within 15 minutes, with some men responding as early as 10 minutes. * **Duration:** The therapeutic window extends up to 6 hours, permitting spontaneous sexual activity without strict timing. * **Metabolism:** Avanafil is metabolized primarily by the hepatic cytochrome P450 3A4 pathway; renal excretion accounts for a minor proportion of the dose. * **Selectivity:** Compared with other PDE5 inhibitors, avanafil exhibits higher selectivity for the PDE5 isozyme, which may reduce off-target effects such as visual disturbances. These mechanisms translate into a reliable and fast-acting treatment for men with ED, while maintaining a safety profile comparable to other agents in its class. --- ## Conditions Treated with Avanafil - **Erectile Dysfunction (ED)** Avanafil improves the ability to achieve and maintain an erection sufficient for sexual intercourse. By enhancing penile blood flow only during sexual stimulation, it avoids undesired erections at other times. - **Psychogenic Erectile Dysfunction** In cases where anxiety or stress contributes to ED, avanafil’s rapid onset can reduce performance pressure, supporting more confident sexual activity. - **Mild to Moderate Vascular-related ED** Men whose erectile problems stem from reduced arterial inflow benefit from avanafil’s potent PDE5 inhibition, which compensates for compromised vascular function. *Note: Avanafil is not approved for the treatment of female sexual dysfunction, pulmonary hypertension, or other conditions.* --- ## Is Avanafil the Right Medication for You? Avanafil is appropriate for adult men who have been diagnosed with erectile dysfunction and who can tolerate sexual activity without contraindicated medications. It is especially useful when a fast-acting response is desired, such as spontaneous intimacy or weekend plans. **Ideal candidates** often include: * Men with mild to moderate ED who prefer a medication that works quickly. * Individuals who have tried other PDE5 inhibitors without adequate response or who experienced bothersome side effects. * Patients who require flexibility in timing, as avanafil can be taken 15 minutes to 2 hours before sexual activity. **Contraindications and cautions**: * Concurrent use of nitrates (e.g., nitroglycerin, isosorbide dinitrate) - may cause severe hypotension. * History of recent (within 30 days) myocardial infarction, stroke, or life-threatening arrhythmia. * Uncontrolled hypertension (> 185/120 mmHg) or severe hypotension (< 90 mmHg). * Anatomical penile deformities (e.g., severe Peyronie’s disease) where sexual activity could cause injury. Patients with liver impairment, renal disease, or who are taking potent CYP3A4 inhibitors should discuss dose adjustments with their clinician. --- ## Buying Avanafil from [our online pharmacy](https://liabilis.com/order-avanafil-online-en.html) ### Why Choose Our Service?

If a dose is missed, simply wait until the next planned sexual activity; do not take an extra tablet to “make up” for the missed dose. **Overdose** Symptoms may include prolonged erection (priapism), severe headache, dizziness, or sudden drop in blood pressure. If overdose is suspected, seek immediate medical attention or contact a poison control center. Treatment may involve prompt removal of the drug from the system and supportive care. **Practical precautions** - Avoid excessive alcohol, which can potentiate blood-pressure-lowering effects. - Do not combine avanafil with other PDE5 inhibitors. - Refrain from operating heavy machinery or driving if you experience dizziness or visual changes. - Food does not significantly affect absorption, but a high-fat meal may delay onset slightly. --- ## Safety Information ### ⚠️ Who Should Not Take Avanafil - Patients using any form of nitrate medication (e.g., nitroglycerin, isosorbide mononitrate). - Men with a known hypersensitivity to avanafil or any tablet excipients. - Individuals with recent (≤ 30 days) cardiovascular events such as myocardial infarction, unstable angina, or stroke. - Patients with severe uncontrolled hypertension (> 185/120 mmHg) or hypotension (< 90 mmHg). ### Common Side Effects - **Headache:** Occurs in up to 20 % of users; usually mild and transient. - **Flushing:** Warmth and redness, often limited to the face or neck. - **Nasal Congestion:** Mild blockage, typically resolves without intervention. - **Back Pain:** Rare, may be related to muscle relaxation. These effects are generally self-limiting and do not require medical attention unless they persist or worsen. ### Serious Side Effects (Seek Immediate Medical Help) - **Priapism:** A prolonged erection lasting more than 4 hours; requires urgent evaluation to prevent permanent tissue damage. - **Severe Hypotension:** Dizziness, fainting, or collapse, especially if combined with nitrates or potent antihypertensives. - **Cardiovascular Events:** Chest pain, palpitations, or signs of myocardial infarction. - **Vision Changes:** Sudden loss of vision or color perception; discontinue use and seek ophthalmologic assessment. ### Drug & Food Interactions - **Nitrates (any formulation):** Concomitant use can cause life-threatening drops in blood pressure. - **Alpha-Blockers (e.g., doxazosin, tamsulosin):** May augment hypotensive effects; dose titration and monitoring are advised. - **CYP3A4 Inhibitors (ketoconazole, clarithromycin, grapefruit juice):** Increase avanafil plasma concentrations; consider lower avanafil dose. - **CYP3A4 Inducers (rifampin, carbamazepine):** Decrease avanafil effectiveness; higher dose may be required under supervision. - **Other PDE5 Inhibitors:** Concurrent use is contraindicated due to additive risk of hypotension and priapism. --- ## Off-Label and Investigational Uses of Avanafil Occasionally, clinicians explore avanafil for conditions beyond erectile dysfunction, guided by emerging research: - **Pulmonary Arterial Hypertension (PAH):** Small pilot studies have examined PDE5 inhibition as a therapeutic strategy, but avanafil is not approved for PAH and lacks robust efficacy data. - **Benign Prostatic Hyperplasia (BPH)-related Lower Urinary Tract Symptoms:** Preliminary investigations suggest potential improvement in urinary flow, yet regulatory approval is absent. These applications remain investigational. Off-label use should only be pursued under direct supervision of a qualified healthcare provider, and patients should be fully informed of the limited evidence base. --- ## Storage & Handling - **Temperature:** Store at 15 °C - 30 °C (59 °F - 86 °F). Do not freeze. - **Light & Humidity:** Keep tablets in the original container, protected from moisture and direct sunlight. - **Shelf Life:** Use within 24 months from the date of manufacture; the expiration date is printed on the packaging. - **Disposal:** Unused tablets should be discarded in accordance with local pharmaceutical waste regulations or returned to a pharmacy take-back program. --- ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I take avanafil after a heavy meal?** Avanafil’s absorption is not markedly affected by food, but a very high-fat meal may delay onset by up to 30 minutes. Taking the tablet with a light snack is usually fine. - **Will alcohol affect avanafil’s effectiveness?** Moderate alcohol consumption typically does not interfere with the drug’s action, but excessive drinking can worsen side effects such as dizziness and lower blood pressure. **Product & Formulation Details** - **What do avanafil tablets look like?** Generic avanafil tablets are round, film-coated, and may be pink (50 mg), blue (100 mg), or white (200 mg). Exact appearance can vary by manufacturer. - **Are there any inactive ingredients I should be aware of?** Common excipients include lactose, microcrystalline cellulose, and magnesium stearate. Patients with lactose intolerance or specific allergies should review the full ingredient list provided by the pharmacy. **Regulatory & Safety Nuances** - **Will avanafil show up on a standard drug test?** Avanafil is not typically screened for in routine occupational drug testing panels. However, specialized testing could detect it if specifically requested. - **Is avanafil safe for men over 65?** Older adults can use avanafil, but clinicians may start with the lowest dose (50 mg) and assess tolerance, particularly because age-related vascular changes can affect blood pressure responses. **Scientific & Clinical Curiosity** - **How does avanafil compare to sildenafil in terms of onset?** Avanafil has a faster reported onset (≈ 15 minutes) compared with sildenafil, which usually requires 30-60 minutes. Both share a similar duration of action, though avanafil’s selectivity may reduce certain side effects. - **What was the key trial that led to FDA approval?** The pivotal Phase III studies (e.g., the AVAN-1 and AVAN-2 trials) demonstrated statistically significant improvements in erection hardness scores versus placebo, supporting a 100 mg dose with a favorable safety profile. --- ## Glossary **Phosphodiesterase-5 (PDE5) Inhibitor** : A class of drugs that block the PDE5 enzyme, preventing degradation of cGMP and thereby facilitating smooth-muscle relaxation in the penis. **cGMP (Cyclic Guanosine Monophosphate)** : A messenger molecule that mediates vasodilation; increased levels promote blood flow necessary for an erection. **Bioequivalence** : The property whereby a generic drug shows no significant difference in rate and extent of absorption compared with the reference branded product. **Priapism** : An erection lasting longer than four hours, unrelated to sexual stimulation, and considered a medical emergency. **Cytochrome P450 3A4 (CYP3A4)** : A liver enzyme responsible for metabolizing many drugs, including avanafil; its activity influences drug levels and potential interactions. --- ## Disclaimer The information provided about **Avanafil** is for general knowledge only.
