What is VIAGRA (SILDENAFIL)?

The drug VIAGRA (SILDENAFIL) is an original medicinal product designed for the effective restoration of impaired erectile function in adult men. This medication belongs to the pharmacotherapeutic group of drugs used in urology, namely selective inhibitors of phosphodiesterase type 5 (a specific enzyme phosphodiesterase type 5). Due to its proven clinical efficacy, this agent is considered the global standard in the therapy of potency disorders of various origins. The drug is available in the form of oral film-coated tablets, which have a characteristic blue color and a biconvex diamond shape.

The original medication was developed and is manufactured by a leading international pharmaceutical company, which guarantees a high degree of purification of raw materials and strict quality control at every stage of production. The physiological mechanism of action of this agent is based on its ability to enhance the natural blood flow to the cavernous bodies of the penis during sexual stimulation. The drug belongs to the category of prescription medicines, which emphasizes the need for a preliminary medical examination before starting its use. Correctly selected therapy allows men to regain confidence in their own strength and significantly improve the quality of their personal life.

It is important to understand that the pharmacological action of the medication manifests itself exclusively in the presence of adequate sexual arousal, as the agent itself is not an artificial stimulant or aphrodisiac. The manufacturer pays special attention to maintaining the stability of the active substance in each dosage unit, which ensures a predictable and reproducible clinical effect. The medicinal product has successfully passed numerous international trials, which confirmed its high safety profile when the instructions are followed. Preserving the patient's health requires a responsible approach, so self-medication with this active pharmaceutical drug is unacceptable.

What is VIAGRA (SILDENAFIL) prescribed for?

The main medical indication for which urologists and andrologists prescribe the drug VIAGRA (SILDENAFIL) is erectile dysfunction, which is defined as the persistent or recurrent inability to achieve or maintain a penile erection necessary for a complete sexual intercourse. This disorder can be caused by vascular pathologies, neurological disorders, hormonal imbalance, or psychogenic factors such as chronic stress, depressive states, and anxiety. Due to its vasodilating effect on the pelvic vessels, the pharmacological agent helps to overcome physical barriers to the normal blood filling of the cavernous bodies.

In addition, the use of this agent is indicated for psychogenic potency disorders, when organic vascular lesions are absent, but the patient experiences fear of possible failure. In such situations, the medication provides reliable physical support, breaking the pathological cycle of anxious expectation and restoring a normal physiological response to stimulation. The drug is also used in the complex therapy of men with a mixed form of erectile dysfunction, which combines both physical and emotional causes of sexual health disorders. Systematic or episodic intake as recommended by a specialist contributes to the harmonization of intimate life.

The medication can be prescribed to patients with concomitant diseases, such as diabetes mellitus or mild arterial hypertension, in whom erection disorders arose as a complication of the main pathological process. Due to its precise targeted effect on the vascular system of the genital organs, the drug allows achieving a stable result even in complex clinical cases. However, the success of therapy directly depends on the accurate diagnosis of the root cause of the disorder. Before starting the course, a detailed consultation with a doctor is required to rule out hidden cardiovascular pathologies.

Composition and active components of VIAGRA (SILDENAFIL)

The main active component that provides the therapeutic effect of the drug VIAGRA (SILDENAFIL) is sildenafil citrate — a potent and highly selective inhibitor of the enzyme phosphodiesterase-5. The molecular mechanism of action of this substance consists in blocking the breakdown of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penile vessels. During sexual stimulation, a local release of nitric oxide occurs, and the level of cGMP preserved due to the medicine causes relaxation of the arterial walls and cavernous tissue. This leads to an intense flow of blood and the occurrence of a natural, physiologically complete erection.

The tablet core contains carefully selected excipients that ensure the stability of the active form, the optimal rate of its dissolution, and maximum bioavailability in the gastrointestinal tract. Such components include microcrystalline cellulose, anhydrous calcium hydrogen phosphate, croscarmellose sodium, and magnesium stearate. They are inert fillers that facilitate the rapid release of the active molecular complex after the oral tablet enters the male digestive system.

The outer film coating contains hypromellose, titanium dioxide, lactose, triacetin, and a special blue lake, which gives the tablet its recognizable patented appearance. All auxiliary ingredients undergo multi-stage pharmaceutical purification and meet the strictest pharmacopoeial safety standards. Since each organism has its own biochemical characteristics, the individual response of the body to excipients may differ, which requires careful study of the instructions by patients with lactase deficiency or allergic tendencies.

Dosage of VIAGRA (SILDENAFIL)

The standard recommended starting dose of VIAGRA (SILDENAFIL) for most adult men is 50 mg, taken as needed approximately one hour before anticipated sexual activity. Depending on individual efficacy and tolerability of the active substance, the dose may be increased by a qualified doctor to the maximum recommended dose of 100 mg, or decreased to 25 mg per day. The maximum recommended frequency of administration is once a day, as exceeding this norm does not increase efficacy but significantly increases the risk of developing adverse reactions.

For elderly patients (aged 65 and older), adjustment of the standard dosage is usually not required; however, in the presence of concomitant hepatic impairment or severe renal insufficiency, the starting dose should be reduced to 25 mg. The same approach with a minimum dosage applies to individuals concurrently taking moderate CYP3A4 inhibitors to avoid excessive accumulation of the active substance in blood plasma. Any changes in the dosage regimen should be carried out exclusively under the supervision of a clinical pharmacologist or andrologist.

The duration of use of this pharmaceutical agent is determined individually and has no time limits, as the drug is used on an "as needed" basis rather than as a daily continuous course. With systematic use, no development of tolerance or decrease in clinical effect is observed, which is confirmed by long-term observations. However, increasing the dose on one's own to accelerate or enhance the effect is strictly prohibited due to the threat of vascular complications.

How to take VIAGRA (SILDENAFIL) correctly?

To achieve maximum pharmacological efficacy, the VIAGRA (SILDENAFIL) tablet should be swallowed whole with a sufficient amount of clean drinking water, approximately 30–60 minutes before planned sexual contact. The optimal time for the onset of action of the drug can vary from 30 to 120 minutes, depending on the individual metabolic rate of the specific man. Taking the tablet with a high-fat meal may delay the absorption of the active substance in the stomach and postpone the onset of the therapeutic effect by 40–60 minutes.

If the intake of the drug was missed for some reason, under no circumstances should a double dose be taken to compensate, as the agent is intended for symptomatic use on demand, not for a fixed calendar schedule. The main caution concerns refraining from the simultaneous consumption of grapefruit or grapefruit juice, as the components of this fruit can block the breakdown of sildenafil in the liver, leading to a toxic increase in its concentration in the systemic circulation.

Before starting to use this medication, a consultation with a doctor is mandatory for a detailed assessment of the state of the cardiovascular system. Men with chronic heart diseases should remember that sexual activity itself is an additional stress for the myocardium. Always take into account that the individual body reaction to the onset time and duration of action of the active component is unique for each patient, so the first doses should be taken in a calm setting.

Side effects of VIAGRA (SILDENAFIL)?

In most cases, VIAGRA (SILDENAFIL) is well tolerated by patients; however, like any highly active medicinal product, it can cause side reactions. The most common undesirable effects occurring in more than 10% of cases include headache, which is usually mild or moderate and quickly resolves on its own. Also common (from 1% to 10% of patients) are hot flushes, skin hyperemia, dizziness, dyspeptic disorders (heartburn, nausea), and nasal congestion due to the systemic vasodilating effect.

Uncommon side effects (from 0.1% to 1%) may include temporary visual disturbances, such as changes in color perception (chromatopsia, when all objects appear to have a blue tinge), increased sensitivity to light, blurred vision, or rapid heartbeat (tachycardia). Very rarely, dry mouth, tinnitus, drowsiness, or muscle and back pain may be observed. In case of any of the listed symptoms that cause discomfort or do not disappear for a long time, it is necessary to notify your doctor.

Rare but critically dangerous conditions include immediate-type allergic reactions (angioedema, urticaria), sudden decrease or loss of hearing, and priapism — a pathologically prolonged (more than 4 hours) and painful erection. If an erection persists for more than 4 hours, immediate emergency medical assistance should be sought, as untimely treatment of priapism can lead to irreversible damage to the penile tissues and permanent impotence.

Contraindications of VIAGRA (SILDENAFIL)

An absolute contraindication to the use of agents containing VIAGRA (SILDENAFIL) is increased individual sensitivity (allergy) to the main component or any excipient of the tablet. The drug is strictly prohibited for patients taking nitric oxide donors, organic nitrates, or nitrites in any form (for example, nitroglycerin), because sildenafil potentiates their hypotensive effect, which can cause a life-threatening drop in blood pressure. Co-administration with guanylate cyclase stimulants (such as riociguat) is also contraindicated.

The medicinal product is categorically prohibited for individuals for whom sexual activity is undesirable due to the presence of severe cardiovascular diseases, such as unstable angina, severe heart failure, recently suffered (within the last 6 months) myocardial infarction or acute cerebrovascular accident (stroke). Other absolute contraindications include severe hepatic impairment, arterial hypotension (blood pressure below 90/50 mmHg), loss of vision due to non-arteritic anterior ischemic optic neuropathy, and hereditary degenerative retinal disorders (e.g., retinitis pigmentosa).

This medication is not intended for use in women, as well as children and adolescents under 18 years of age. Special caution and individual dose adjustment are required for patients with anatomical deformation of the penis (Peyronie's disease), predisposition to priapism (in sickle cell anemia, multiple myeloma, leukemia), and exacerbation of peptic ulcer disease. A complete examination by a doctor is a prerequisite for safe treatment.

Interaction of VIAGRA (SILDENAFIL) with other drugs and alcohol

Concomitant use of VIAGRA (SILDENAFIL) with potent inhibitors of the CYP3A4 isoenzyme (such as ketoconazole, erythromycin, ritonavir) leads to a significant increase in sildenafil concentration in blood serum, which requires the use of minimum doses. The agent should be prescribed with particular caution to patients receiving alpha-blockers for the treatment of hypertension or prostate adenoma, as such a combination can cause symptomatic orthostatic hypotension (a sharp drop in blood pressure when changing body position). Simultaneous use with other oral or topical agents for the treatment of erectile dysfunction is prohibited.

The consumption of alcoholic beverages during therapy with this medication is not recommended, as ethanol itself suppresses the function of the central nervous system and is capable of impairing erectile function, neutralizing the beneficial pharmacological effect. In addition, the combination of large doses of alcohol with sildenafil significantly increases the risk of developing side effects such as dizziness, orthostatic hypotension, headache, and rapid heartbeat. Regarding driving: due to the possibility of dizziness and visual disturbances, patients should assess their individual response to the drug before driving.
