Sildenafil Citrate Tablets Cenforce 100mgx100Tablets

[Product Name] Sildenafil Citrate Tablets (Viagra)

[English Name] Sildenafil Citrate Tablets

[Ingredients] Each tablet contains sildenafil citrate equivalent to 100 mg of sildenafil.

[Specification] 100 tablets/box

[Description] This product is a blue, film-coated tablet; the core appears white after the coating is removed.

[Indications] Sildenafil citrate tablets are indicated for the treatment of erectile dysfunction.

[Dosage and Administration]

For most patients, the recommended dose is 50 mg, taken approximately 1 hour before sexual activity; however, it may be taken anywhere from 0.5 to 4 hours prior to sexual activity. Based on efficacy and tolerability, the dose may be increased to 100 mg (the maximum recommended dose) or decreased to 25 mg. The maximum frequency of use is once daily.

[Adverse Reactions]

Headache, flushing, dyspepsia, nasal congestion, and visual abnormalities. Visual abnormalities are mild and transient, primarily manifesting as altered color perception (tinged vision), increased sensitivity to light, or blurred vision.

[Contraindications]

Use is contraindicated in patients taking any form of nitrate medication, whether regularly or intermittently. Use is prohibited in patients with a known hypersensitivity to any component of sildenafil (Viagra).

[Pharmacology and Toxicology]

This product is an oral medication for the treatment of erectile dysfunction; it is the citrate salt of sildenafil, a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Mechanism of Action: The physiological mechanism of penile erection involves the release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. NO activates guanylate cyclase, leading to increased levels of cGMP, which causes smooth muscle relaxation in the corpus cavernosum and allows for blood engorgement. 【Drug Interactions】

Effects of other drugs on sildenafil: In vitro studies indicate that the drug is metabolized primarily via cytochrome P450 3A4 (major pathway) and 2C9 (minor pathway).

【Pharmacokinetics】

Following oral administration, the drug is rapidly absorbed, reaching peak plasma concentrations in 30–120 minutes and taking effect within 1 hour. Bioavailability is approximately 40%. Food significantly reduces the rate and extent of absorption and delays the onset of action. The drug undergoes hepatic metabolism mediated primarily by CYP3A4 into active metabolites; approximately 80% is excreted in feces and 13% in urine, with less than 0.001% excreted in semen. The half-life of both the parent drug and the active metabolite is 4 hours. Clearance is reduced in elderly men (over 65 years of age) and in patients with hepatic impairment or severe renal impairment.

【Precautions】

The interaction between sildenafil and nitrates affecting blood pressure can persist throughout the 6-hour observation period following administration. Therefore, the co-administration of sildenafil with organic nitrates or nitric oxide (NO) donors (such as sodium nitroprusside) is contraindicated under any circumstances. Use sildenafil with caution in patients with anatomical penile deformities (e.g., angulation, cavernosal fibrosis, Peyronie's disease) or conditions that predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, leukemia). The safety and efficacy of combining this drug with other treatments for erectile dysfunction have not been studied; such combination use is not recommended. In the presence of existing cardiovascular risk factors, sexual activity following drug administration carries a risk of non-fatal or fatal cardiac events. Sexual activity must be discontinued if symptoms such as angina, dizziness, or nausea occur upon initiation of sexual activity. Since the drug's approval for marketing abroad, there have been rare reports of prolonged erections (lasting more than 4 hours) and priapism (painful erections lasting more than 6 hours). Patients should seek immediate medical attention if an erection persists for more than 4 hours. If priapism (prolonged erection) is not treated immediately, penile tissue damage may occur, potentially leading to permanent erectile dysfunction. Sildenafil offers no protection against sexually transmitted diseases.

[Use in Pregnant and Lactating Women] Sildenafil is not indicated for use in newborns, children, or women.

[Use in the Elderly] Clearance of sildenafil is reduced in healthy elderly volunteers (≥65 years of age). Given that higher plasma concentrations may increase both efficacy and the incidence of adverse events, a starting dose of 25 mg is recommended.

[Storage] Store in a cool area (below 20°C).

Important Information for Purchasing Sexual Health Products:

Note: Oral medications for erectile support in men require sexual stimulation to be effective; they do not induce erections automatically.

When using drugs containing sildenafil, vardenafil, tadalafil, avanafil, or Priligy (dapoxetine), many users are concerned about the possibility of not achieving the desired results.

Based on clinical data and real-world user feedback, there are slight variations in the proportion of non-responders across different medications:

Sildenafil: Approximately 15%–20% of users do not achieve the expected results;

Vardenafil: The proportion of non-responders is similar to that of sildenafil, at approximately 15%–22%;

Tadalafil: Due to its longer half-life and slightly broader suitability, the non-response rate is slightly lower, at approximately 12%–18%;

Avanafil: Acts quickly and is metabolized rapidly; the non-response rate is approximately 14%–19%;

Priligy (dapoxetine): Targeted at premature ejaculation; efficacy is significantly influenced by individual nerve sensitivity and psychological state, resulting in a relatively higher non-response rate of approximately 20%–25%. It is important to clarify that if some users do not experience satisfactory results, it is not due to product quality issues; rather, it is the result of the interplay between the drug's mechanism of action and the individual's physiological and pathological conditions. Even the original brand-name products—such as Pfizer’s Viagra (sildenafil)—are ineffective for a significant percentage of men (approximately 20%). It is common for the same medication to work for one person but not another, or for a different product to be effective for someone else while proving ineffective for you. This store guarantees that all sexual health products are 100% authentic, but we cannot guarantee that every user will achieve the expected results; please consider this carefully before placing an order.

Specific reasons vary by medication:

Sildenafil / Vardenafil / Avanafil: These three drugs work by promoting vasodilation. Their effectiveness is influenced by individual metabolic capacity (liver and kidney function affecting the rate of drug breakdown), underlying medical conditions (such as diabetes or hypertension, which damage blood vessels and reduce drug efficiency), and usage context (alcohol consumption inhibits effectiveness, while high-fat meals may delay the absorption of sildenafil and vardenafil). If severe arterial disease is present, the drug struggles to facilitate blood flow, naturally limiting its effectiveness.

Tadalafil: Although its mechanism is similar to the three drugs mentioned above, it remains in the body longer. However, its efficacy is still influenced by factors such as individual drug sensitivity and the presence of severe prostate disease or spinal cord injuries. Some individuals may experience suboptimal results due to weaker receptor binding affinity.

Priligy (Dapoxetine): This drug improves ejaculation control by inhibiting neurotransmitter reuptake. Its effectiveness is closely linked to individual nerve conduction efficiency, psychological state (anxiety and tension can counteract the drug's effects), and whether the dosage is appropriate for the user's body weight and the severity of the condition. If there is abnormal nerve sensitivity or long-standing psychogenic premature ejaculation, the drug's regulatory effect may be limited.

If you do not achieve the expected results after using any of the aforementioned drugs or dual-effect tablets, please avoid arbitrarily increasing the dosage, switching medications, or continuing long-term use without guidance; it is recommended that you consult a urologist or andrologist. A doctor will assess your physical condition through a detailed consultation and adjust your medication regimen based on test results (e.g., optimizing dosage or switching medication types). They may also incorporate psychological interventions or behavioral training to create a treatment plan best suited to your needs.
