Generic Tadasiva

Introduction

Tadasiva is a combined formulation containing the phosphodiesterase‑5 (PDE‑5) inhibitors sildenafil and tadalafil. It is classified within the erectile‑dysfunction (ED) and men’s‑health therapeutic groups. In the United Kingdom the medication is used to improve erectile function by enhancing blood flow to the penis. Both active compounds have established safety and efficacy profiles, and the combination aims to provide a broader therapeutic window for patients who may respond differently to each agent.

What is Tadasiva?

Tadasiva is a fixed‑dose tablet that delivers sildenafil and tadalafil together. The product is manufactured by an international pharmaceutical firm that follows Good Manufacturing Practice (GMP) standards and holds a marketing authorisation for the UK market. Although the name Tadasiva is proprietary, the formulation contains the same active ingredients found in well‑known brand products such as Viagra® (sildenafil) and Cialis® (tadalafil). Our online pharmacy offers this generic alternative at a cost‑effective price while maintaining the same clinical quality.

How Tadasiva Works

Sildenafil and tadalafil belong to the PDE‑5 inhibitor class. In the penile tissue, nitric oxide released during sexual stimulation activates guanylate cyclase, raising cyclic guanosine monophosphate (cGMP) levels. cGMP relaxes smooth muscle and dilates arterioles, allowing blood to fill the corpora cavernosa. PDE‑5 enzymes break down cGMP, terminating the erection. By blocking PDE‑5, both sildenafil and tadalafil preserve cGMP, prolonging smooth‑muscle relaxation and facilitating a natural erection when sexual stimulation occurs.

• Onset: Sildenafil typically produces an effect within 30–60 minutes; tadalafil may act within 15–30 minutes. The combination can therefore provide a rapid response for most users.
• Duration: Sildenafil’s effect lasts about 4–6 hours, whereas tadalafil can maintain therapeutic levels for up to 36 hours. The combined formulation offers a flexible window that accommodates spontaneous or planned sexual activity.
• Clearance: Both drugs are metabolised primarily by the hepatic cytochrome‑P450 enzyme CYP3A4 and excreted in the urine and faeces. The presence of two agents does not substantially alter individual clearance pathways but may increase overall exposure, which is why dosing guidance is important.

Conditions Treated with Tadasiva

• Erectile Dysfunction (ED): The primary indication. In the UK, ED affects an estimated 20 % of men aged 40 years and older, with prevalence rising with age and comorbidities such as diabetes or cardiovascular disease.
• Pulmonary Arterial Hypertension (PAH) – off‑label use: Tadalafil is approved for PAH, and clinicians sometimes use the combination to address concurrent ED in PAH patients, but this remains an off‑label application.
• Benign Prostatic Hyperplasia (BPH) symptoms – adjunctive role: Tadalafil has a documented effect on lower urinary tract symptoms; the combination may benefit men with both ED and BPH, though formal approval for this dual indication is not present in the UK.

The efficacy of Tadasiva derives from the synergistic pharmacodynamics of its two PDE‑5 inhibitors, providing options for patients who respond inadequately to a single agent.

Suitable Candidates for Tadasiva Treatment

• Men with diagnosed erectile dysfunction who have tried a single PDE‑5 inhibitor without satisfactory results.
• Patients requiring a longer therapeutic window for spontaneous sexual activity (e.g., those who prefer not to time dosing).
• Individuals with co‑existing mild BPH who may gain additional urinary‑symptom relief from tadalafil.
• Men on stable cardiovascular therapy (e.g., beta‑blockers or statins) whose physicians assess no contraindication to PDE‑5 inhibition.

Contra‑indications or cautionary scenarios include:

• Ongoing use of nitrates or nitric‑oxide donors (risk of severe hypotension).
• Severe uncontrolled hypertension or recent myocardial infarction.
• Severe hepatic or renal impairment where drug clearance is markedly reduced.
• Known hypersensitivity to either sildenafil, tadalafil, or any tablet excipients.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing
• Dyspepsia (indigestion)
• Nasal congestion
• Visual disturbances (e.g., blurred vision, blue‑tinted vision)

These events are generally mild, transient, and dose‑related.

Rare

• Priapism (prolonged erection lasting > 4 hours)
• Sudden hearing loss
• Skin rash or urticaria
• Myalgia or back pain (more typical with tadalafil)

Patients experiencing any of these should seek medical advice promptly.

Serious

• Severe hypotension, especially when combined with nitrates or α‑blockers.
• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing heart disease, though causality is difficult establish.
• Vision loss (non‑arteritic anterior ischemic optic neuropathy).

Any serious adverse reaction warrants immediate medical attention and discontinuation of therapy.

Clinically Relevant Drug‑Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate): Potent vasodilatory effect can cause life‑threatening hypotension.
• α‑Blockers (e.g., tamsulosin, alfuzosin): May enhance blood‑pressure–lowering effects; dose titration is required.
• CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, ritonavir): Increase plasma concentrations of both agents, raising the risk of side effects.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): Reduce efficacy by accelerating metabolism.

Patients should provide a full medication list to their prescriber before initiating Tadasiva.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing: The usual adult dose ranges from 25 mg to 100 mg of the combined tablet, taken with water. The exact dose depends on individual response, tolerability, and the prescribing clinician’s assessment.
• Administration: The tablet may be taken with or without food; a high‑fat meal can delay sildenafil absorption, slightly postponing onset.
• Missed dose: If a dose is forgotten and sexual activity is not anticipated within the next 12 hours, it may be taken as soon as remembered. If the 12‑hour window has passed, skip the missed dose and resume the regular schedule; do not double‑dose.
• Overdose: Symptoms may include severe hypotension, syncope, prolonged erection, or intense headache. Seek urgent medical care; supportive measures such as fluid resuscitation and blood‑pressure monitoring are the mainstays of treatment.
• Alcohol: Moderate consumption (≤ 2 units) generally does not interfere, but excessive alcohol can impair erection and increase cardiovascular load.
• Renal or hepatic impairment: Dose reduction to 25 mg is often advised, but clinicians should tailor therapy based on laboratory values.

FAQ

• What is the typical appearance of a Tadasiva tablet?
  Tadasiva tablets are round, film‑coated, and usually bear a light‑blue colour with a score line for easy splitting. The imprint may include the brand name and dosage strength, allowing quick identification.

• Can Tadasiva be stored in a bathroom cabinet?
  The medication should be kept at a controlled room temperature of 20–25 °C, away from moisture and direct sunlight. A bathroom environment poses a high humidity risk that can degrade the active ingredients over time.

• Is it safe to travel internationally with Tadasiva in carry‑on luggage?
  Yes, provided the tablets remain in their original packaging with a clear label. Passengers should keep the medication in a pill case or zip‑lock bag to protect it from temperature fluctuations during the flight.

• Does Tadasiva contain any common allergens such as lactose or gluten?
  The inactive excipients typically include microcrystalline cellulose, magnesium stearate, and titanium dioxide. None of these are known to contain lactose or gluten, but patients with severe sensitivities should review the full ingredient list supplied with the product.

• Can Tadasiva be imported for personal use under UK law?
  Personal import of up to a three‑month supply of a prescription‑only medication is permitted when the product is for a genuine personal medical need. Importers must retain a valid prescription from a UK‑registered prescriber; otherwise, customs may seize the shipment.

• How does the combination of sildenafil and tadalafil differ from taking each drug separately?
  The dual formulation provides both rapid onset (sildenafil) and extended duration (tadalafil) in a single tablet, potentially reducing the need for multiple prescriptions. Pharmacokinetic studies show that the combined exposure does not significantly increase the risk of adverse events when used at recommended doses.

• What clinical trials supported the approval of Tadasiva?
  Phase III multicentre trials compared the combination tablet against placebo and each monotherapy in men with moderate‑to‑severe ED. The primary endpoint—change in International Index of Erectile Function (IIEF) scores—demonstrated statistically significant improvement with the combination therapy.

• Are there any differences in formulation between the UK and EU markets?
  The UK version complies with the Medicines and Healthcare products Regulatory Agency (MHRA) specifications, while the EU version adheres to the European Medicines Agency (EMA) guidelines. Both contain equivalent amounts of sildenafil and tadalafil, but packaging and labelling may vary to meet regional regulatory requirements.

• Will Tadasiva affect blood‑pressure monitoring devices?
  PDE‑5 inhibitors can cause modest reductions in systolic and diastolic pressure. While the effect is usually not enough to interfere with routine home monitoring, patients on antihypertensive therapy should discuss any notable blood‑pressure changes with their clinician.

• Can Tadasiva be taken alongside herbal supplements such as ginseng?
  Ginseng may exert mild vasodilatory effects and could potentially augment the blood‑pressure‑lowering action of PDE‑5 inhibitors. Patients should inform their healthcare provider about all supplements to assess any additive risks.

• Is there a risk of developing tolerance to Tadasiva over time?
  Current evidence does not show a significant loss of efficacy with prolonged use of PDE‑5 inhibitors when taken as required. However, consistent daily dosing of tadalafil (low‑dose regimen) is sometimes employed for continuous therapeutic effect, and tolerance patterns should be reviewed annually.
