ZHEWITRA 20

Vardenafil is known as one of the most reliable and highly selective PDE5 inhibitors. ZHEWITRA 20 is a generic containing 20 mg of Vardenafil, which is the maximum recommended daily dose. The medication is intended for the effective treatment of erectile dysfunction (ED), providing a firm and stable erection.

What is ZHEWITRA 20?

ZHEWITRA 20 is an oral tablet medication containing 20 mg of Vardenafil. Vardenafil is the active substance of the original "Levitra."

1. Indication and target dosage

The 20 mg Vardenafil dose is the maximum recommended daily dose and is indicated for the treatment of moderate to severe ED. ZHEWITRA 20 is ideally suited for:

• Men who require the maximum standard efficacy of Vardenafil.

• Patients for whom the initial 10 mg dose proved insufficient.

• Patients with coexisting conditions (e.g., diabetes) where Vardenafil has shown high efficacy.

2. Advantages of Vardenafil

Vardenafil is valued for its high selectivity for the PDE5 enzyme. This ensures a potent effect on the penile blood vessels with minimal impact on other systems. Due to this, ZHEWITRA 20 less frequently causes vision-related side effects ("blue haze") than Sildenafil.

Detailed mechanism of action of ZHEWITRA 20

The mechanism of action of ZHEWITRA 20 is based on Vardenafil 20 mg being a highly selective inhibitor of the PDE5 enzyme.

1. Trigger: Sexual arousal causes the release of nitric oxide (NO).

2. Erectile Cycle: NO stimulates the formation of cyclic GMP (cGMP), which relaxes the smooth muscles of the penile blood vessels, ensuring a powerful blood flow.

3. Blockade: Vardenafil blocks the PDE5 enzyme that degrades cGMP. Blocking this enzyme allows cGMP to persist longer, manifold enhancing the natural blood flow and ensuring a stable, firm erection.

Key takeaway: Vardenafil in ZHEWITRA 20 works as an enhancer of the natural response. Sexual arousal is required for an erection to occur.

Instructions for using ZHEWITRA 20

Strict adherence to the instructions is necessary for safety and maximum efficacy.

1. Dosage and method of intake

• Dosage: 20 mg (one tablet) – is the maximum daily dose. It is strictly prohibited to exceed 20 mg within 24 hours.

• Initial Dose: If you are trying Vardenafil for the first time, it is recommended to start with 10 mg (half a tablet). The ZHEWITRA 20 tablet is easily split.

• Method: The tablet should be swallowed whole with water.

• Timing: Take 30–60 minutes before planned sexual activity. The effect lasts 4–6 hours.

2. Influence of food and alcohol

• Food: ZHEWITRA 20 can be taken regardless of food. However, a fatty meal may slightly slow down the onset of action.

• Alcohol: Vardenafil is considered one of the most alcohol-friendly drugs in its class. Nevertheless, it is not recommended to combine ZHEWITRA 20 with excessive amounts of alcohol, as this can increase the risk of dropping blood pressure and dizziness.

Critical contraindications for ZHEWITRA 20

The list of contraindications must be reviewed with a doctor.

• Interaction with Nitrates: Absolutely forbidden! Taking ZHEWITRA 20 with any form of organic nitrates (Nitroglycerin) or nitric oxide donors ("poppers") causes a life-threatening drop in blood pressure.

• Severe Cardiovascular Diseases: Recent heart attack or stroke (within 6 months), unstable angina, severe heart failure.

• Blood Pressure: Persistent hypotension (pressure < 90/50 mmHg) or uncontrolled hypertension.

• Liver and Kidneys: Severe hepatic or renal failure.

Side effects of ZHEWITRA 20

Vardenafil 20 mg is generally well-tolerated and has a favourable side effect profile.

• Common: Headache (the most frequent effect), facial flushing, nasal congestion.

• Less Common: Dyspepsia (indigestion), dizziness, back pain (less common than with Tadalafil).

• Visual Risk: Vardenafil has a very low risk of color vision disturbances.

Immediate medical attention is required for: An erection that lasts longer than 4 hours (priapism), or sudden loss of vision/hearing.

Professional advice on using ZHEWITRA 20

1. Optimal Dose: 20 mg is optimal, but starting with 10 mg (half a tablet) is advisable if you are a new user.

2. Choice for Diabetics: Vardenafil has demonstrated high efficacy in men with diabetes.

3. Dosing Flexibility: Start with 10 mg and only progress to the full 20 mg tablet if 10 mg proves insufficient.
