Viagra

What is it?

Composition

The composition of the drug Viagra is carefully selected to ensure efficiency and safety. The main active ingredient is sildenafil citrate, which actively affects the mechanisms responsible for erection. The composition of the drug also contains additional components that stabilize the shape of the tablet and ensure its durability.

Here are the main components of Viagra:

• Sildenafil citrate is an active component that increases blood flow to the penis.
• Microcrystalline cellulose - ensures uniform distribution of the active substance.
• Sodium croscarmellose - helps the tablet dissolve faster in the stomach.
• Magnesium stearate - used as a binder.
• Lactose is an additional filler that improves the taste and structure of the tablet.

Additional components are included to maintain the quality of the drug and facilitate its use.

How to use?

For maximum effectiveness, Viagra should be used as directed by your doctor and as instructed. Taking the correct dosage and time of administration is key to ensuring the safe and effective action of the drug.

Directions for use:

1. The drug is taken orally with plenty of water. Do not chew the tablet.
2. The optimal time to take it is 30-60 minutes before the expected sexual intercourse. This time allows the active substance to fully activate in the body.
3. The recommended initial dose is 50 mg. If necessary and on the recommendation of a doctor, the dosage can be increased to 100 mg or decreased to 25 mg, depending on tolerance.
4. The maximum frequency of use is once a day. Increasing the frequency may lead to unwanted side effects.

The drug should not be combined with fatty foods, as this may slow down its absorption and reduce its effectiveness.

How does it work?

The mechanism of action of Viagra is based on the ability of the active substance, sildenafil, to influence certain physiological processes in the body. The drug affects the enzyme phosphodiesterase type 5 (PDE-5), which is responsible for the destruction of cyclic guanosine monophosphate (cGMP). This enzyme plays an important role in regulating blood flow in the cavernous bodies of the penis.

After taking Viagra, the following happens:

• Under the influence of sexual stimulation, the body begins to produce nitric oxide, which activates the production of cGMP.
• Sildenafil blocks the action of PDE-5, which helps to increase the level of cGMP.
• Increased cGMP levels relax muscles and dilate blood vessels in the cavernous bodies, ensuring blood flow.
• The result of this process is an erection, which is necessary for sexual intercourse.

The drug is effective only in the presence of sexual arousal, which makes its action natural. Viagra does not have a systemic effect on blood vessels in other parts of the body, which minimizes the risk of unwanted effects.

Indications

Viagra is used to solve problems associated with erectile dysfunction. The main goal of the drug is to help men suffering from erectile dysfunction to restore the ability to have full sexual intercourse. The effectiveness of the drug has been proven by numerous clinical studies and practical experience.

Indications for use include:

• Erectile dysfunction, in which it is impossible to achieve or maintain an erection sufficient for sexual intercourse.
• Age-related changes affecting potency, including those associated with decreased testosterone levels.
• Conditions caused by stress, fatigue or psychological discomfort affecting sexual function.
• Decreased sexual desire and self-confidence caused by physiological or emotional reasons.

Viagra helps to restore the joy of intimate life, but prior consultation with a doctor is recommended for its use.

Contraindications

Viagra, like any medical drug, has a number of contraindications that are important to consider before using. Failure to follow the recommendations may lead to deterioration of health and development of adverse reactions. Before taking it, it is important to consult a doctor and make sure there are no contraindications.

The main contraindications include:

• Allergy or hypersensitivity to sildenafil or any other components of the drug.
• Concomitant use of nitrates or nitric oxide donors, as this may lead to a dangerous decrease in blood pressure.
• Severe cardiovascular disease, including recent myocardial infarction or stroke.
• Arterial hypotension (low blood pressure).
• The presence of retinal diseases, such as retinitis pigmentosa, associated with genetic disorders.
• Conditions in which physical activity is contraindicated, for example, with unstable angina.

Side effects

Like any medication, Viagra can cause side effects. These are usually temporary and disappear as the body gets used to the drug. However, it is important to be aware of possible reactions in order to take timely measures and, if necessary, consult a doctor.

The most common side effects include:

• Headaches are the most common complaint among users.
• Flushing of the face or a feeling of warmth.
• Indigestion or a feeling of heaviness in the stomach.
• Runny or stuffy nose.
• Dizziness, especially when standing up suddenly.

Less common:

• Vision changes, such as a slight change in color perception.
• Rapid heartbeat or a feeling of irregular heartbeat.
• Muscle pain or back pain.

In rare cases, serious side effects are possible, such as a prolonged painful erection (priapism) or a sudden decrease in vision. If these symptoms occur, you should seek immediate medical attention.
