Intagra

Introduction

Intagra is a pharmaceutical product used primarily to treat erectile dysfunction (ED) in adult men. It contains the active compound sildenafil, the same molecule found in the well‑known brand Viagra. Sildenafil belongs to the phosphodiesterase‑type 5 (PDE5) inhibitor class, which facilitates erection by enhancing blood flow to the penis. In the United Kingdom, Intagra is marketed within the men's health sector and is prescribed when a patient requires a reliable, fast‑acting oral therapy for ED. Although its main indication is erectile dysfunction, sildenafil is also approved for the treatment of pulmonary arterial hypertension (PAH) under separate brand formulations; however, Intagra is not marketed for PAH.

What is Intagra?

Intagra is the generic version of Viagra, containing the same active compound sildenafil. Our online pharmacy provides this generic alternative as a cost‑effective treatment option. The product is manufactured by licensed pharmaceutical companies that meet European Union Good Manufacturing Practice (GMP) standards. As a generic, Intagra offers the identical therapeutic profile of the original brand at a lower price, making it accessible to patients who may face financial barriers or limited insurance coverage.

Key points:

• Active ingredient: Sildenafil citrate (100 mg per tablet in the standard strength).
• Therapeutic class: PDE5 inhibitor for erectile dysfunction.
• Regulatory status: Authorized for prescription use in the UK under the MHRA (Medicines and Healthcare products Regulatory Agency).

How Intagra Works

Sildenafil exerts its effect by selectively inhibiting the enzyme phosphodiesterase‑type 5 (PDE5). In the presence of sexual stimulation, nitric oxide is released in the corpus cavernosum, stimulating the production of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscle, allowing blood to fill the penile tissue and produce an erection. PDE5 normally degrades cGMP, terminating the erection. By blocking PDE5, sildenafil prolongs the action of cGMP, thereby maintaining smooth‑muscle relaxation and enhanced blood flow.

Pharmacokinetic profile relevant to patients:

• Onset of action: Typically 30–60 minutes after oral ingestion.
• Peak plasma concentration: Reached within 1 hour when taken on an empty stomach; food, especially high‑fat meals, can delay absorption.
• Duration of effect: Efficacy may persist for up to 4–6 hours, providing a therapeutic window for sexual activity.
• Elimination: Primarily hepatic metabolism via CYP 3A4, with renal excretion of metabolites. The drug’s half‑life is approximately 4 hours.

Conditions Treated with Intagra

Intagra is approved for the treatment of erectile dysfunction, a condition affecting an estimated 20 % of men in the UK at some point in their lives. ED can stem from vascular, neurological, hormonal, or psychological origins. By improving penile blood flow, sildenafil directly addresses the vascular component, which is the most common cause.

Approved indication in the UK:

• Erectile Dysfunction (ED): Facilitates erection sufficient for sexual intercourse when taken as required before sexual activity.

The drug is not officially approved for other indications in the UK, though off‑label use for conditions such as lower urinary tract symptoms has been investigated in clinical research.

Who is Intagra For?

Intagra is suitable for adult men who meet the following criteria:

• Diagnosed erectile dysfunction: Men who have a confirmed diagnosis of ED after appropriate medical evaluation.
• Age range: Typically prescribed for adults aged 18 years and older; safety in younger patients has not been established.
• Absence of contraindications: Patients without a history of severe cardiovascular disease, uncontrolled hypertension, or use of nitrate medications.

Clinical scenarios where Intagra is often recommended:

• Vasculogenic ED: Men whose ED is primarily due to impaired arterial blood flow.
• Diabetes‑associated ED: Individuals with diabetes mellitus experiencing endothelial dysfunction.
• Psychogenic ED: Patients whose ED has a psychological component but also benefits from physiological support.

Situations where Intagra may be inappropriate:

• Concurrent nitrate therapy: Co‑administration with nitrates (e.g., nitroglycerin) can cause dangerous hypotension.
• Severe hepatic impairment: Reduced metabolism may increase systemic exposure.
• Retinitis pigmentosa or hereditary retinal disorders: Sildenafil may affect retinal function.

Risks, Side Effects, and Interactions

Common

• Headache – mild to moderate, usually resolves without intervention.
• Flushing – warmth and reddening of the face, neck, or chest.
• Indigestion – dyspepsia or a feeling of fullness.
• Nasal congestion – transient blockage of nasal passages.

Rare

• Visual disturbances – bluish tint to vision, increased light sensitivity, or difficulty distinguishing colors.
• Priapism – prolonged erection lasting more than 4 hours; requires urgent medical attention.
• Hearing loss – sudden decrease or loss of hearing, reported in isolated cases.

Serious

• Severe hypotension – especially when combined with nitrates or alpha‑blockers, may lead to syncope or shock.
• Cardiovascular events – myocardial infarction or stroke in patients with pre‑existing cardiac disease.
• Allergic reactions – rash, itching, swelling, or anaphylaxis.

Clinically Relevant Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Concomitant use can precipitate profound hypotension.
• Alpha‑blockers (e.g., doxazosin, tamsulosin): May amplify blood‑pressure‑lowering effects.
• CYP 3A4 inhibitors (e.g., ketoconazole, erythromycin, ritonavir): Increase sildenafil plasma concentrations, potentially intensifying side effects.
• CYP 3A4 inducers (e.g., rifampicin, carbamazepine): Reduce drug exposure, possibly decreasing efficacy.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their healthcare provider before initiating Intagra.

Practical Use: Dosing, Missed Dose, Overdose

Standard dosing recommendations (UK guidance):

• Starting dose: 50 mg taken as needed, approximately 30 minutes before sexual activity.
• Dose adjustment: Based on efficacy and tolerability, the dose may be increased to 100 mg or decreased to 25 mg.
• Maximum frequency: No more than one dose per 24 hours.

Missed dose: Intagra is taken only when sexual activity is anticipated. If a dose is missed, it should simply be omitted; there is no requirement for a “make‑up” dose.

Overdose management:

• Signs of overdose: Excessive hypotension, severe headache, visual disturbances, or prolonged erection.
• Immediate actions: Seek medical attention promptly; supportive care includes maintaining blood pressure and managing priapism if present.

Practical precautions:

• Food: A high‑fat meal can delay absorption; for more predictable onset, take Intagra on an empty stomach.
• Alcohol: Moderate alcohol consumption does not usually interfere, but excessive intake may impair erection and increase side‑effect risk.
• Comorbidities: Patients with severe renal or hepatic impairment should consult a clinician for possible dose reduction.

FAQ

• Is Intagra available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product is marketed as Viagra, while Intagra represents the generic formulation containing the same active ingredient, sildenafil. Generic versions are typically less expensive while offering identical therapeutic effects.

• What is the best way to store Intagra tablets?
  Store tablets at room temperature (15–30 °C). Keep them in a dry place, away from direct sunlight, heat sources, and moisture. Do not store them in bathrooms or near kitchen sinks where humidity is high.

• Can Intagra be safely imported into the UK for personal use?
  Personal import of prescription medicines is permitted under UK law provided the product is for personal use, the quantity does not exceed a three‑month supply, and it is sourced from a licensed overseas pharmacy. Importation should comply with MHRA guidelines.

• Does taking Intagra with a high‑fat meal affect its efficacy?
  A high‑fat meal can delay sildenafil absorption, potentially extending the onset from 30 minutes to up to 2 hours. The overall efficacy remains unchanged, but timing of sexual activity may need adjustment.

• What are the inactive ingredients in Intagra tablets?
  Common excipients include microcrystalline cellulose, lactose monohydrate, magnesium stearate, and calcium hydrogen phosphate. These components aid tablet formation and dissolution but have no therapeutic activity.

• Is there a difference between Intagra formulations sold in the EU versus other regions?
  EU‑approved generics must meet strict bioequivalence standards, matching the reference brand in strength, purity, and dissolution profile. Formulations marketed outside the EU may have minor variations in inert fillers but must still contain 100 % sildenafil citrate.

• How does chronic alcohol consumption impact Intagra’s safety profile?
  Chronic excessive alcohol use can exacerbate hypertension and cardiovascular disease, increasing the risk of hypotension when combined with sildenafil. Moderation is recommended to minimise adverse events.

• Can Intagra be taken by men with hypertension?
  Men with well‑controlled hypertension may safely use sildenafil. However, those with severe or uncontrolled high blood pressure should consult a clinician, as the vasodilatory effect of the drug could further lower blood pressure.

• What is the mechanism behind priapism associated with sildenafil?
  Priapism arises when prolonged vasodilation maintains excessive blood flow in the corpora cavernosa, preventing normal detumescence. While rare, it is a medical emergency that requires prompt intervention to avoid permanent tissue damage.

• Are there any known interactions between Intagra and over‑the‑counter supplements?
  Certain supplements—such as high‑dose L‑arginine, yohimbine, or St John’s wort—may influence CYP 3A4 metabolism, potentially altering sildenafil levels. Patients should discuss all supplement use with their healthcare provider.
