Generic Sildalist

Introduction

Sildalist is a pharmaceutical product formulated for the treatment of erectile dysfunction (ED) in adult men living in the United Kingdom. It contains two well‑established phosphodiesterase‑5 (PDE5) inhibitors—sildenafil and tadalafil—delivered together in a single oral dosage form. The combination targets the same physiological pathway that governs penile erection, offering an alternative for men who have not achieved satisfactory results with a single‑agent regimen. Although primarily indicated for ED, both active compounds have documented secondary uses, such as the management of pulmonary arterial hypertension, which may be relevant in specialised clinical contexts.

What is Sildalist?

Sildalist is a fixed‑dose combination tablet that combines the active ingredients sildenafil and tadalafil. Both agents belong to the PDE5‑inhibitor class and are licensed for the treatment of erectile dysfunction. The product is manufactured by an established pharmaceutical supplier (manufacturer details are disclosed on the packaging) and distributed in the UK under the generic name Sildalist.

• Generic version of well‑known brand‑name drugs:
  • Viagra®, which contains sildenafil.
  • Cialis®, which contains tadalafil.

Our online pharmacy provides this generic alternative as a cost‑effective treatment option, delivering the same active molecules without the premium brand price.

How Sildalist Works

Sildenafil and tadalafil inhibit the enzyme phosphodiesterase‑5 (PDE5) that normally degrades cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis. During sexual stimulation, nitric oxide is released, stimulating the production of cGMP. Elevated cGMP relaxes smooth muscle, allowing blood to fill the erectile tissue and produce an erection. By blocking PDE5, both sildenafil and tadalafil prolong the cGMP signal, enhancing the natural erectile response.

The two agents differ in pharmacokinetic properties:

• Sildenafil reaches peak plasma concentrations within 30–120 minutes and has a half‑life of approximately 4 hours.
• Tadalafil peaks later (around 2 hours) but maintains therapeutic levels for up to 36 hours because of its longer half‑life (≈17.5 hours).

When combined, the formulation aims to provide a rapid onset of action (from sildenafil) together with an extended therapeutic window (from tadalafil), potentially improving flexibility for spontaneous sexual activity.

Conditions Treated with Sildalist

• Erectile Dysfunction (ED) – The primary indication. In the UK, about 18 % of men aged 40‑70 report persistent ED, making it a common urological concern.
• Pulmonary Arterial Hypertension (PAH) – Both sildenafil and tadalafil have separate approvals for PAH; the combination may be employed off‑label under specialist supervision when monotherapy is insufficient.

The dual‑drug approach is considered when a patient has experienced suboptimal response to either sildenafil or tadalafil alone, or when variable timing of sexual activity necessitates both rapid onset and prolonged effect.

Who is Sildalist For?

• Men with confirmed erectile dysfunction who have not achieved consistent erection quality on a single PDE5 inhibitor.
• Patients requiring flexible timing—those who desire both quick onset (sildenafil) for spontaneous encounters and extended duration (tadalafil) for planned activity later in the day.
• Individuals under specialist care for pulmonary arterial hypertension who may benefit from combined PDE5 inhibition under strict clinical monitoring.

Contra‑indications / situations where Sildalist is not appropriate

• Men taking nitrates (e.g., nitroglycerin) or nitric‑oxide donors, because the combination can cause severe hypotension.
• Patients with severe uncontrolled hypertension, recent myocardial infarction, or unstable angina.
• Individuals with known hypersensitivity to either sildenafil, tadalafil, or any excipients in the tablet.
• Men with certain retinal disorders (e.g., inherited retinal dystrophy) due to potential visual side effects.

Risks, Side Effects, and Interactions

Common

• Headache
• Flushing (warmth and redness, especially of the face)
• Dyspepsia (indigestion)
• Nasal congestion
• Mild back or muscle pain (more typical with tadalafil)

These events are usually mild to moderate and resolve without medical intervention within a few hours.

Rare

• Dizziness or light‑headedness
• Priapism (prolonged erection lasting > 4 hours) – requires urgent medical attention.
• Vision changes such as a bluish tinge or blurred vision (linked to sildenafil’s effect on PDE6 in the retina).

Serious

• Severe hypotension, especially when combined with nitrates or alpha‑blockers.
• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing heart disease.
• Sudden hearing loss, which has been reported rarely with PDE5 inhibitors.

Drug–drug interactions

• Nitrates (nitroglycerin, isosorbide dinitrate) – contraindicated.
• Alpha‑blockers (e.g., tamsulosin, doxazosin) – may cause additive blood pressure effects; dose adjustment required.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, ritonavir) – increase plasma concentrations of both sildenafil and tadalafil, heightening side‑effect risk.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine) – reduce effectiveness of the PDE5 inhibitors.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to a qualified healthcare professional before starting Sildalist.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing (adults) – The tablet is typically available in fixed ratios (e.g., 50 mg sildenafil + 5 mg tadalafil). The usual starting dose is one tablet taken with water, no earlier than 30 minutes before anticipated sexual activity. Do not exceed one tablet per 24 hours.
• Missed dose – If an erection does not occur, a second dose should not be taken within the same 24‑hour period. Wait for the next scheduled dosing interval.
• Overdose – Symptoms may include severe hypotension, prolonged erection, or fainting. Seek immediate medical assistance. Activated charcoal may be considered if ingestion occurred within one hour and the patient presents early.

Precautions

• Food: A high‑fat meal can delay sildenafil’s onset by up to an hour; tadalafil is less affected.
• Alcohol: Moderate consumption is generally safe, but excessive alcohol may impair erection and increase hypotensive risk.
• Renal or hepatic impairment: Dose reduction may be required; clinicians should assess renal function (eGFR) and liver enzymes before prescribing.

FAQ

• What is the typical appearance of a Sildalist tablet?
  The tablet is usually round, bicolour (half blue, half white), and imprint‑marked with “SL‑50/5” to indicate the combined dose of sildenafil and tadalafil.

• Can Sildalist be taken with a high‑fat meal?
  A high‑fat meal may delay the onset of sildenafil’s effect by 30‑60 minutes, while tadalafil is less affected. For optimal timing, consider taking the tablet on an empty stomach or after a light meal.

• Is refrigeration required for Sildalist storage?
  No. Store the tablets at controlled room temperature (15‑30 °C). Protect them from excessive heat, moisture, and direct sunlight to maintain potency.

• How long can a Sildalist tablet be kept after opening the blister pack?
  Once a tablet is removed, it should be used within 30 days, provided it remains in its original packaging and is stored as recommended.

• Are there any differences in the inactive ingredients between UK and overseas batches?
  In the UK, manufacturers use standard excipients such as lactose, microcrystalline cellulose, and magnesium stearate. Overseas formulations may contain equivalent agents, but patients with specific allergies should verify the full ingredient list before purchase.

• Can Sildalist be imported for personal use under UK law?
  Yes. Personal importation of a 3‑month supply of a prescription medicine for personal use is permitted, provided it is for a legitimate medical need and the quantity does not exceed the allowed limit. Our service complies with all relevant import regulations.

• Will Sildalist show up on a standard drug test?
  Standard workplace drug screens do not test for PDE5 inhibitors. However, specialized testing can detect sildenafil or tadalafil if specifically requested.

• What was the original development pathway for combining sildenafil and tadalafil?
  Both drugs were independently discovered in the early 199s (sildenafil in 1991, tadalafil in 1993) and approved for erectile dysfunction in 1998 and 2003, respectively. The concept of a fixed‑dose combination emerged later to address variable timing needs, though it remains an off‑label strategy in most jurisdictions.

• How does the efficacy of the combination compare with taking each drug separately?
  Clinical observations suggest that the combination can provide both rapid onset and prolonged duration, potentially improving spontaneity. However, head‑to‑head randomized trials are limited; individual response varies, and safety monitoring is essential.

• Are there any specific warnings for men of Asian descent?
  Pharmacogenomic studies indicate that some Asian populations may experience higher plasma levels of sildenafil due to genetic variations in CYP3A4. Dose adjustments or careful monitoring are advisable, especially when combined with tadalafil.

• What packaging does Sildalist receive when ordered online?
  Orders are dispatched in a tamper‑evident, discreet cardboard box containing a sealed plastic blister pack. Each box includes a printed patient information leaflet in English.
