Pharmaceutical Viagra 200mg x 500

Description

Classification

Pharmaceutical Viagra 200mg x 500 is marketed as an oral product containing sildenafil, a phosphodiesterase type-5 (PDE5) inhibitor used to treat erectile dysfunction in adult men. Viagra is the established brand name for sildenafil.

However, 200mg is not a standard UK-authorised Viagra tablet strength. UK product information recommends sildenafil doses of 25mg, 50mg or 100mg for erectile dysfunction, with 100mg as the maximum recommended dose.

The stated 200mg x 500 therefore refers to the advertised product strength and quantity, rather than an approved dosage.

What is Pharmaceutical Viagra 200mg x 500?

Pharmaceutical Viagra 200mg x 500 describes a product marketed as containing 200mg of sildenafil per tablet, supplied as 500 tablets.

Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping men who have difficulty achieving or maintaining an erection.

Important product information includes:

• Active ingredient and stated strength
• Manufacturer details
• Batch or lot number
• Expiry date
• Packaging integrity
• Marketing authorisation information
• Certificate of analysis, where available

A product name or pharmaceutical-style packaging does not independently confirm authenticity or UK authorisation.

Dosage

For UK-authorised sildenafil products used for erectile dysfunction, the usual recommended dose is 50mg when required, approximately one hour before sexual activity. Depending on effectiveness and tolerability, the dose may be reduced to 25mg or increased to 100mg. The maximum recommended frequency is once daily.

200mg is above the recommended maximum dose for erectile dysfunction. It should not be treated as a standard or appropriate individual dose.

How Does Pharmaceutical Viagra 200mg x 500 Work?

Sildenafil inhibits phosphodiesterase type-5 (PDE5). During sexual stimulation, nitric oxide signalling increases cyclic GMP in penile tissue. Sildenafil helps prevent the breakdown of cyclic GMP, supporting smooth-muscle relaxation and increased penile blood flow.

Sexual stimulation is still required for sildenafil to produce an erection.

Benefits

The established therapeutic use of Viagra/sildenafil is the treatment of erectile dysfunction in adult men.

Potential benefits include:

• Supporting the ability to achieve an erection
• Helping maintain an erection during sexual activity
• Improving erectile firmness
• Supporting sexual confidence where erectile dysfunction is a concern

Sildenafil does not directly increase sexual desire and does not protect against sexually transmitted infections.

When Should You Not Take Pharmaceutical Viagra 200mg x 500?

Sildenafil is not suitable for everyone. It must not be taken with nitrate medicines or nitric oxide donors, including certain treatments for angina, because the combination can cause a potentially dangerous reduction in blood pressure.

Particular caution is required for people with:

• Significant cardiovascular disease
• Recent heart attack or stroke
• Low blood pressure
• Severe liver impairment
• Certain inherited retinal disorders
• Certain heart conditions
• Previous loss of vision associated with NAION

Because 200mg exceeds the recommended maximum dose, this particular strength warrants additional caution.

What is the Mechanism of Pharmaceutical Viagra 200mg x 500?

Sildenafil selectively inhibits the PDE5 enzyme, which normally breaks down cyclic GMP. Increased cyclic GMP activity helps relax smooth muscle in the corpus cavernosum and increase penile blood flow during sexual stimulation.

This mechanism supports erectile function but does not create sexual desire or an erection independently of sexual stimulation.

Uses of Pharmaceutical Viagra 200mg x 500

Sildenafil is used primarily for erectile dysfunction in adult men. It is also available in different formulations and strengths for pulmonary arterial hypertension, but these are separate licensed uses and dosing regimens.

For erectile dysfunction, relevant therapeutic use includes:

• Difficulty achieving an erection
• Difficulty maintaining an erection
• Erectile dysfunction associated with underlying health conditions

The marketed 200mg product should not be assumed to have an approved UK indication simply because it carries the Viagra name.

Warnings and Precautions for Pharmaceutical Viagra 200mg x 500

Sildenafil can affect blood pressure and cardiovascular function. Higher doses can increase the frequency and severity of adverse reactions. UK product information reports that doses of 200mg did not provide increased efficacy but did increase adverse reactions compared with lower doses.

Important precautions include:

• Never combine sildenafil with nitrate medicines.
• Do not combine it with other PDE5 inhibitors.
• Tell your doctor about existing heart conditions.
• Discuss alpha-blockers and blood-pressure medicines before use.
• Avoid excessive alcohol consumption.
• Seek urgent medical attention for a prolonged erection.
• Seek medical advice for sudden vision or hearing changes.

Side Effects of Pharmaceutical Viagra 200mg x 500

Potential side effects associated with sildenafil include:

• Headache
• Flushing
• Indigestion
• Nasal congestion
• Dizziness
• Nausea
• Visual disturbances

Higher doses may increase the frequency and severity of adverse reactions. Serious reactions can include severe cardiovascular symptoms, significant allergic reactions, sudden vision or hearing loss and priapism, a prolonged erection requiring urgent medical treatment.
