Avana Information

Introduction

Avana is a prescription medication used primarily for the treatment of erectile dysfunction (ED) in adult males. The product contains the active pharmaceutical ingredient avanafil, a selective phosphodiesterase‑type 5 (PDE5) inhibitor. Avana belongs to the men's health therapeutic class and is approved for use in Hong Kong under the same indications as its branded counterparts. While avanafil is marketed under several brand names worldwide, Avana provides a generic, cost‑effective alternative for patients seeking reliable ED therapy.

What is Avana?

Avana is the generic version of Stendra (United States) and Spedra (European Union), containing the same active compound avanafil. Our online pharmacy provides this generic alternative as a cost‑effective treatment option. Avanafil was developed by pharmaceutical company Pfizer and later licensed to various manufacturers for generic production. The medication is classified as a selective PDE5 inhibitor, a class of drugs that enhances erectile response by modulating the nitric‑oxide–cGMP pathway in penile tissue.

How Avana Works

Avanafil inhibits the enzyme phosphodiesterase‑type 5, which normally degrades cyclic guanosine monophosphate (cGMP) in the smooth muscle of the corpus cavernosum. By blocking PDE5, avanafil prolongs cGMP accumulation after sexual stimulation. Elevated cGMP leads to smooth‑muscle relaxation, increased blood flow into the penis, and the development of an erection.

Key pharmacologic characteristics:

• Onset of action: clinical trials report erectile response in as little as 15 minutes after oral administration, making avanafil one of the fastest‑acting PDE5 inhibitors.
• Duration: therapeutic effect typically lasts 6–12 hours, allowing flexibility in timing of sexual activity.
• Metabolism and clearance: avanafil is metabolised principally by hepatic CYP3A4 and CYP2C9 enzymes; the half‑life is approximately 5 hours, and renal excretion accounts for a minor proportion of clearance.

These properties translate into a rapid, predictable response for most patients when taken as directed.

Conditions Treated with Avana

• Erectile Dysfunction (ED): the sole FDA‑ and HKHA‑approved indication. ED prevalence in Hong Kong is estimated at 13–19 % among men over 40 years, reflecting both physiological and psychosocial contributors.
• Off‑label use for Pulmonary Hypertension: avanafil has been investigated in early‑phase studies for pulmonary arterial hypertension, but it is not approved for this indication in Hong Kong.

Avana’s efficacy in ED is supported by multiple randomized, double‑blind, placebo‑controlled trials demonstrating statistically significant improvements in the International Index of Erectile Function (IIEF) scores compared with placebo.

Patient Groups Most Likely to Benefit

• Men with mild to moderate ED: those who experience occasional difficulty achieving or maintaining an erection and who respond well to PDE5 inhibition.
• Patients requiring rapid onset: individuals who prefer spontaneity and appreciate the 15‑minute onset profile.
• Men on concomitant nitrate therapy: avanafil, like other PDE5 inhibitors, is contraindicated with nitrates; therefore, patients not using nitrates are suitable candidates.
• Patients with mild hepatic impairment: dose adjustment is generally unnecessary for mild liver disease, making avanafil a convenient option.

Contraindications / cautions:

• Severe hepatic or renal impairment (Child‑Pugh class C or creatinine clearance < 30 mL/min) may require dose reduction or avoidance.
• Concurrent use of potent CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) can increase avanafil plasma concentrations, elevating risk of adverse events.
• Patients with a history of priapism, retinal disorders, or uncontrolled hypertension should be evaluated carefully before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing
• Nasal congestion
• Dyspepsia (indigestion)
• Back pain or muscle aches (typically mild and transient)

Rare

• Visual disturbances (blurred vision, changes in color perception)
• Hearing loss or tinnitus
• Dermatologic reactions (rash, pruritus)
• Elevated liver enzymes (transient)

Serious

• Priapism (prolonged erection > 4 hours) – requires immediate medical attention to prevent tissue damage.
• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing risk factors.
• Severe hypotension, especially when combined with nitrates or alpha‑blockers.

Drug–drug interactions of clinical relevance:

• Nitrates (nitroglycerin, isosorbide dinitrate) – co‑administration can cause dangerous hypotension; contraindicated.
• Alpha‑blockers (tamsulosin, alfuzosin) – may lead to additive blood‑pressure lowering; initiate avana at the lowest dose and monitor.
• Strong CYP3A4 inhibitors (ketoconazole, clarithromycin, ritonavir) – increase avanafil exposure; consider dose reduction or alternative therapy.
• CYP3A4 inducers (rifampin, carbamazepine) – may decrease effectiveness; monitor response.

Patients should disclose all concomitant medications, including over‑the‑counter products and herbal supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard starting dose: 100 mg taken as needed, not more than once per day.
• Alternative dosing: 50 mg or 200 mg can be prescribed based on efficacy and tolerance.
• Administration: swallow tablet whole with water; oral intake may be taken with or without food. A high‑fat meal can delay absorption but does not diminish overall effectiveness.
• Missed dose: because avanafil is taken on an as‑needed basis, there is no “daily” dosing schedule. If an erection does not occur within 30 minutes, the patient may take another dose only after a full 24‑hour interval has elapsed.
• Overdose management: symptoms of overdose include severe headache, flushing, hypotension, and prolonged erection. Patients should seek immediate medical attention; supportive care such as intravenous fluids and blood pressure monitoring is standard.
• Precautions: avoid excessive alcohol consumption, which can potentiate hypotensive effects. Patients with uncontrolled hypertension (> 170/100 mmHg) should treat blood pressure before initiating avana.
