Generic Tadasiva Information

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. The product is marketed for adult males in Hong Kong who experience difficulty attaining or maintaining an erection sufficient for satisfactory sexual activity. Both active compounds have well‑established roles in improving penile blood flow, and the combination aims to provide flexible onset and prolonged duration of effect.

What is Tadasiva?

Tadasiva is the generic version of the well‑known brand‑name medications Viagra® (sildenafil) and Cialis® (tadalafil). It contains the same active ingredients—sildenafil and tadalafil—in concentrations that meet the standards set by the US Food and Drug Administration (FDA) and the Hong Kong Department of Health. The formulation is produced by a licensed pharmaceutical manufacturer that complies with Good Manufacturing Practice (GMP). Our online pharmacy provides this generic alternative as a cost‑effective treatment option for men seeking reliable ED therapy without the premium price of brand‑name products.

How Tadasiva Works

Sildenafil and tadalafil belong to the PDE‑5 inhibitor class. In normal penile physiology, sexual stimulation releases nitric oxide (NO) in the corpus cavernosum. NO activates guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP). Elevated cGMP relaxes smooth muscle and permits inflow of arterial blood, producing an erection.

PDE‑5 enzymes degrade cGMP, terminating the erection. Sildenafil competitively inhibits PDE‑5 with a rapid onset (30–60 minutes) but a relatively short duration (≈4–6 hours). Tadalafil also inhibits PDE‑5 but binds with a longer half‑life (≈17.5 hours), allowing a therapeutic window of up to 36 hours. By combining the two agents, Tadasiva offers an early onset from sildenafil together with the extended penile rigidity afforded by tadalafil, giving patients greater spontaneity and flexibility in sexual activity.

Conditions Treated with Tadasiva

• Erectile Dysfunction (ED) – The primary indication. ED affects an estimated 1.5 million men in Hong Kong, with prevalence increasing with age and comorbidities such as diabetes, hypertension, and cardiovascular disease.
• Pulmonary Arterial Hypertension (PAH) – off‑label – Both sildenafil and tadalafil have FDA‑approved uses for PAH; however, the combined product is not formally licensed for this indication in Hong Kong. Clinicians may consider it only within a specialist‑approved protocol.

The dual‑mechanism improves erection quality across a broader range of physiological and psychological triggers, making it suitable for patients who experience variable response to a single PDE‑5 inhibitor.

Who is Tadasiva For?

• Men aged 18 years and older with a confirmed diagnosis of ED who can achieve sexual stimulation.
• Patients who have responded inadequately to a single PDE‑5 inhibitor (e.g., either sildenafil or tadalafil alone) and require a broader therapeutic window.
• Individuals with predictable timing constraints (need rapid onset) and those who desire flexibility for spontaneous activity later in the day.

Tadasiva is not appropriate for:

• Patients taking nitrates (e.g., nitroglycerin) or nitric oxide donors, because combined vasodilation can cause severe hypotension.
• Men with a history of non‑arteritic anterior ischemic optic neuropathy (NAION) or severe uncontrolled hypertension.
• Individuals with severe hepatic or renal impairment without dose adjustment and specialist supervision.

Risks, Side Effects, and Interactions

Common

• Headache
• Facial flushing
• Dyspepsia (indigestion)
• Nasal congestion
• Myalgia (muscle pain)

These events occur in ≥5 % of users and are usually mild to moderate, resolving without intervention.

Rare

• Visual disturbances (e.g., blue‑tinted vision, blurred vision)
• Auditory changes (tinnitus, hearing loss)
• Priapism (prolonged erection lasting >4 hours)

Rare events appear in <1 % of patients and should prompt immediate medical evaluation.

Serious

• Severe hypotension, especially when combined with nitrate medication
• Acute myocardial infarction or stroke in patients with pre‑existing cardiovascular disease
• Life‑threatening allergic reactions (anaphylaxis, angioedema)

Any serious adverse event requires urgent emergency care.

Clinically Relevant Drug–Drug Interactions

• Nitrates (e.g., glyceryl trinitrate, isosorbide dinitrate): Potent additive vasodilatory effect → marked hypotension.
• Alpha‑blockers (e.g., doxazosin, tamsulosin): May cause additive blood pressure reduction; dose titration recommended.
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): Increase plasma levels of both sildenafil and tadalafil → higher risk of side effects; dose reduction advised.
• CYP3A4 inducers (e.g., rifampin, carbamazepine): Decrease efficacy by accelerating drug clearance.

Patients should disclose all current medications, including herbal supplements, to their healthcare provider before initiating Tadasiva.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing:
  • Sildenafil component: 25 mg to 50 mg taken 30–60 minutes before sexual activity; not to exceed one dose per 24 hours.
  • Tadalafil component: 2.5 mg to 5 mg taken once daily at the same time each day, allowing continuous therapeutic coverage.

Dose selection depends on individual efficacy, tolerability, and concomitant medical conditions. Initiation typically starts at the lower end of each range, with gradual titration under medical supervision.

• Missed dose:

  • If a daily tadalafil dose is missed, take it as soon as remembered unless it is within 12 hours of the next scheduled dose; in that case, skip the missed dose and resume the regular schedule.
  • Missed sildenafil doses do not require rescheduling; simply wait for the next opportunity.

• Overdose:

  • Symptoms may include severe headache, flushing, hypotension, and visual changes.
  • Seek immediate medical attention; supportive care (IV fluids, blood pressure monitoring) is the mainstay of treatment.

Precautions:

• High‑fat meals can delay sildenafil absorption; advise taking the medication with a light meal or after fasting for optimal onset.
• Excessive alcohol consumption may potentiate hypotensive effects and diminish erection quality; limit intake.
• Patients with cardiovascular disease should undergo cardiac evaluation before use.

FAQ

• Is Tadasiva available in both tablet and liquid formulations?
  Tadasiva is currently marketed only as oral tablets containing fixed doses of sildenafil and tadalafil. No liquid or chewable versions have been approved for sale in Hong Kong.

• What should I do if I travel abroad with Tadasiva?
  Keep the medication in its original sealed packaging, carry a copy of the prescribing information, and store it at room temperature away from direct sunlight. Check the destination country’s import regulations to ensure personal import of prescription‑only medicines is permitted.

• Does the addition of tadalafil affect the shelf life of the tablets?
  The combined formulation is stable for up to 24 months when stored at 20–25 °C (68–77 °F) in a dry environment. Exposure to excess heat or moisture can reduce potency, so avoid storage in bathrooms or car trunks.

• Are there any known differences in how Asian populations metabolize Tadasiva?
  Genetic polymorphisms in CYP3A4 and CYP2C9 can modestly affect drug clearance among East Asian individuals, potentially leading to slightly higher plasma concentrations. Dose adjustments may be considered by a clinician based on tolerability.

• Can Tadasiva be taken with over‑the‑counter supplements such as ginseng?
  Ginseng has mild vasodilatory properties and may enhance the hypotensive effect of PDE‑5 inhibitors. While occasional use is unlikely to cause serious problems, patients should discuss regular supplement use with their healthcare provider.

• What packaging does Tadasiva come in when ordered online?
  Each shipment includes a sealed blister pack containing the prescribed number of tablets, accompanied by a printed insert with dosage instructions, safety information, and a batch number for verification.

• Is a temperature-controlled shipment required for Tadasiva?
  No. The tablets are stable at standard ambient temperatures and do not require refrigeration during transit. However, extreme temperatures (above 30 °C for prolonged periods) should be avoided.

• Does Tadasiva appear on standard drug‑testing panels for employment screening?
  PDE‑5 inhibitors are not typically included in routine workplace drug screens. Only specialized testing would detect the presence of sildenafil or tadalafil.

• How does Tadasiva compare to taking sildenafil and tadalafil separately?
  The fixed‑dose combination offers convenience and ensures a consistent ratio of the two agents, potentially improving adherence. Pharmacologically, the effect is equivalent to taking each drug individually, provided the total daily dose does not exceed recommended limits.

• Can Tadasiva be used in men with mild renal impairment?
  In patients with mild to moderate renal dysfunction (creatinine clearance 30–80 mL/min), no dosage adjustment is generally required, but clinicians may monitor for increased side‑effects and adjust if necessary.
