VIAGRA

What is VIAGRA?

The drug VIAGRA is an original medicinal product designed for the effective treatment of erectile dysfunction of various origins in adult men. This medication belongs to the pharmacotherapeutic group of urological drugs, specifically selective phosphodiesterase type 5 inhibitors. The dosage form is available as film-coated tablets, which have a characteristic diamond shape and a blue color to prevent counterfeiting. The original drug was developed and is manufactured by Pfizer, a leading international pharmaceutical company, which guarantees the highest level of quality and strict control at all stages of production.

The mechanism of action of this pharmacological agent is based on restoring impaired erectile function by increasing blood flow to the corpora cavernosa of the penis during sexual stimulation. The drug does not create artificial arousal, but only naturally restores the physiological response of the male body to a sexual stimulus. Due to the high specificity of the active substance, the therapeutic effect is achieved locally, minimizing systemic effects on other human organs and systems. Years of experience in use and numerous clinical studies confirm the high efficacy and relative safety of this pharmacological product.

It should be noted that the therapeutic effect of the medication is temporary and aimed at eliminating symptoms rather than completely curing the root cause of the disease. The effectiveness of the agent directly depends on the proper functioning of the patient's nervous and vascular systems, as well as on the presence of adequate sexual desire. The use of this pharmaceutical product requires preliminary diagnostics to rule out contraindications and determine the optimal treatment regimen. This medicinal product must be stored out of reach of children under the appropriate temperature conditions specified in the instructions.

What is VIAGRA prescribed for?

The primary and only clinical indication for the use of VIAGRA is erectile dysfunction, which is defined as the inability to achieve or maintain a penile erection sufficient for satisfactory sexual performance. This condition can be caused by organic, psychogenic, or mixed factors, including stress, vascular pathologies, and diabetes mellitus. The use of this agent allows men to regain self-confidence and significantly improve the quality of their intimate life. It must be emphasized that a mandatory condition for the manifestation of the pharmacological action of the medicine is the presence of natural sexual stimulation.

The medicinal product effectively helps patients with vascular disorders, where the blood flow to the pelvic organs is insufficient for a full physiological reaction. As a result of the relaxation of the smooth muscles of the arteries, maximum filling of the cavernous bodies occurs, ensuring a stable and prolonged erection. In addition, the drug shows high results in the treatment of men with a psychogenic form of disorders, relieving anxiety associated with the expectation of failure. The medication normalizes natural biochemical processes, returning the body's ability to respond adequately to a sexual stimulus.

The use of this pharmacological agent is also possible as part of complex therapy for secondary erectile dysfunction caused by certain somatic diseases or the intake of certain medications. However, the decision on the advisability of prescription is made exclusively by a specialist after a full medical examination. It should be remembered that this agent is not an aphrodisiac, does not increase libido, and does not protect against sexually transmitted infections. Before starting the course, a detailed consultation with a doctor is required to assess the state of the cardiovascular system.

Composition and active components of VIAGRA

The main active substance of VIAGRA is sildenafil in the form of sildenafil citrate, which is a potent and selective inhibitor of cGMP-specific phosphodiesterase type 5. During sexual stimulation, nitric oxide is released from the nerve endings of the cavernous bodies, which activates the enzyme guanylate cyclase. This leads to an increase in the level of cyclic guanosine monophosphate, causing relaxation of smooth muscles and increased blood flow. Sildenafil inhibits the breakdown of cGMP by the PDE-5 enzyme, thereby offering a natural approach to restoring erectile function.

The tablet core contains excipients that ensure the stability of physical and chemical properties and the required release rate of the active component. Among them are microcrystalline cellulose, anhydrous calcium hydrogen phosphate, croscarmellose sodium, and magnesium stearate. The film coating contains hypromellose, titanium dioxide, lactose monohydrate, triacetin, and a special blue lake based on indigo carmine. All ingredients undergo multi-stage purification and meet the strictest pharmacopoeia standards.

VIAGRA Dosage

For most adult patients, the recommended starting dose of VIAGRA is 50 mg, taken as needed approximately one hour before anticipated sexual activity. Depending on individual efficacy and tolerability of the agent by the body, the dosage may be increased to a maximum single dose of 100 mg or decreased to 25 mg. The maximum recommended frequency of administration is once a day, and exceeding this limit is strictly prohibited. Uncontrolled increase of the dose does not enhance the effect, but significantly increases the risk of developing severe adverse reactions.

For elderly patients (over 65 years old), adjustment of the standard dose is usually not required, but in the presence of concomitant pathologies, the starting dose is recommended to be reduced to 25 mg. Men with hepatic impairment or severe renal impairment are also prescribed a minimum starting dose of 25 mg due to slower clearance of the substance. The duration of drug use is determined individually by the doctor in each specific case. Always remember the need for prior consultation with a medical specialist before changing the dosage.

How to take VIAGRA correctly?

The VIAGRA tablet should be swallowed whole, without chewing or crushing, with a sufficient amount of plain drinking water. The time of onset of the effect is usually 30 to 60 minutes after administration, but this interval may increase when taken with fatty food. Fatty meals slow down the absorption of the active substance in the gastrointestinal tract, which delays the onset of the drug's action. To achieve the fastest and most pronounced result, it is recommended to take the medication on an empty stomach or after a light snack.

If the patient missed the planned time of administration, they should not take a double dose to compensate, as the drug is used directly before intercourse, rather than on a strict schedule. It is important to remember the possible individual reaction of the body, because of which the time of onset and duration of action may differ in different people. During therapy, consumption of grapefruit and grapefruit juice should be avoided, as they can increase the concentration of sildenafil in the blood. Be sure to inform your doctor about all concomitant medications you take on a regular basis.

Side effects of VIAGRA

The most common side effects when using VIAGRA are headache, flushing, dyspeptic disorders, and nasal congestion. Patients may also experience temporary visual disturbances, such as changes in color perception (objects appearing tinged with blue), increased sensitivity to light, or blurred vision. These symptoms are usually mild or moderate in nature and resolve on their own after the active substance stops working. Dizziness, palpitations, muscle pain, or dry mouth may occur uncommonly.

Rare but serious adverse reactions include arterial hypotension or hypertension, syncope, epistaxis, and sudden decrease or loss of hearing. In rare cases, the development of priapism is possible — a prolonged and painful erection lasting more than 4 hours. If such a condition occurs, it is necessary to seek immediate emergency medical assistance to prevent damage to the tissues of the penis. It is important to closely monitor your body's reaction to the medication and report any unusual sensations to your treating physician.

Contraindications of VIAGRA

An absolute contraindication to the use of VIAGRA is hypersensitivity to sildenafil or any of the excipients of the drug. Concomitant use of the agent with nitric oxide donors, organic nitrates, or nitrites in any form is strictly prohibited, as this can cause a life-threatening drop in blood pressure. It is also contraindicated to use the medication in patients for whom sexual activity is inadvisable due to severe cardiovascular diseases, such as unstable angina or severe heart failure.

The drug is not prescribed to patients who have lost vision in one eye due to non-arteritic anterior ischemic optic neuropathy, as well as to persons with severe hepatic impairment. Contraindications include recently suffered stroke or myocardial infarction, arterial hypotension (blood pressure below 90/50 mmHg), and hereditary degenerative retinal disorders. This pharmaceutical product is categorically not intended for use by women, children, and adolescents under 18 years of age. Before starting use, a mandatory consultation with a doctor is required to rule out hidden pathologies.

Interaction of VIAGRA with other drugs and alcohol

Concomitant use of VIAGRA with CYP3A4 inhibitors (such as ketoconazole, erythromycin, ritonavir) leads to an increase in sildenafil plasma concentration, which requires dose adjustment. Combination with alpha-blockers used to treat arterial hypertension or prostatic hyperplasia may cause symptomatic hypotension in some patients. It is forbidden to combine this agent with other oral or local treatments for erectile dysfunction. The effect on the ability to drive vehicles may be negative in case of dizziness or visual disturbances.

The consumption of alcoholic beverages during therapy with this agent significantly reduces the likelihood of achieving a satisfactory erection and increases the risk of side effects such as dizziness and hypotension. Ethanol has a depressant effect on the central nervous system and vascular tone, which negates the pharmacological effect of the drug. To ensure maximum safety and efficacy of treatment, it is recommended to completely abstain from alcohol on the day of taking the tablet. Any combinations with other medications must be agreed with a specialist.
