Generic Tadalafil Information

Introduction

Tadalafil is a phosphodiesterase‑5 (PDE5) inhibitor approved for the treatment of erectile dysfunction (ED) and for the management of pulmonary arterial hypertension (PAH) under the brand name Adcirca. In Hong Kong, the drug is listed on the Pharmacy and Poisons Ordinance and is prescribed by clinicians for men who experience difficulty achieving or maintaining an erection, as well as for patients with PAH. The active compound, tadalafil, belongs to the larger group of erectile‑dysfunction therapies that improve sexual performance and, in a separate indication, support cardiovascular function.

What is Tadalafil?

Tadalafil is the generic version of Cialis (and for PAH, Adcirca), containing the same active compound, tadalafil. It was developed by the pharmaceutical company Lilly (Eli Lilly and Company) and received its first regulatory approval in the United States in 2003. The medication is supplied as film‑coated tablets in strengths of 2.5 mg, 5 mg, 10 mg and 20 mg. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, delivering the same pharmacological profile as the branded products while reducing out‑of‑pocket expenses for patients in Hong Kong.

How Tadalafil Works

Tadalafil selectively inhibits the enzyme phosphodiesterase‑5, which is responsible for breaking down cyclic guanosine monophosphate (cG · MP) in smooth‑muscle cells. In the corpus cavernosum of the penis, sexual stimulation releases nitric oxide, which raises cG · MP levels and leads to smooth‑muscle relaxation, increased blood flow, and erection. By preventing cG · MP degradation, tadalafil prolongs this vasodilatory effect, allowing an erection to develop and be sustained in response to sexual arousal.

In the pulmonary circulation, increased cG · MP causes dilation of pulmonary arterial smooth muscle, reducing arterial pressure and improving exercise capacity in PAH patients. Tadalafil’s pharmacokinetic profile is characterized by a rapid onset (typically 30–60 minutes) and an extended half‑life of approximately 17.5 hours, which supports once‑daily dosing for PAH and “as‑needed” dosing for ED with a therapeutic window that can last up to 36 hours.

Conditions Treated with Tadalafil

• Erectile Dysfunction (ED) – The most common indication. ED affects an estimated 10 % of men in Hong Kong older than 40 years, with prevalence increasing with age and comorbidities such as diabetes and hypertension.
• Pulmonary Arterial Hypertension (PAH) – PAH prevalence in Hong Kong is roughly 15–25 cases per million adults. T improves six‑minute walk distance and delays clinical deterioration.
• Benign Prostatic Hyperplasia (BPH) – off‑label – Some clinicians use tadalafil (5 mg daily) to relieve lower‑urinary‑tract symptoms, supported by modest evidence from randomized trials, though it is not a formally approved indication in Hong Kong.

Tadalafil is effective for each condition because it directly targets the physiological pathways that limit blood flow (penile or pulmonary) or smooth‑muscle tone (prostate).

Suitable Candidates for Tadalafil Treatment

• Men with documented erectile dysfunction who have normal cardiovascular status or whose cardiac condition is stable enough for sexual activity.
• Patients with confirmed pulmonary arterial hypertension (Group 1) who are receiving specialist care and require oral therapy in addition to or instead of injectable agents.
• Individuals who require a longer therapeutic window (e.g., weekend use, spontaneous sexual activity) may prefer tadalafil over shorter‑acting PDE5 inhibitors.
• Patients who can tolerate oral medication and have no contraindications such as concurrent nitrate therapy, severe hypotension, or hereditary retinal disorders.

Contraindications include: concurrent use of nitrates (e.g., nitroglycerin), recent (< 24 h) use of recreational phosphodiesterase inhibitors, uncontrolled hypertension, severe hepatic impairment, and known hypersensitivity to tadalafil or any tablet excipient.

Risks, Side Effects, and Interactions

Common

• Headache
• Dyspepsia (indigestion)
• Back pain (usually mild and transient)
• Myalgia (muscle aches)
• Nasal congestion

These events are generally dose‑related, self‑limiting, and resolve without medical intervention within 24–48 hours.

Rare

• Visual disturbances (blurred vision, color perception changes)
• Hearing loss or tinnitus
• Priapism (prolonged erection > 4 hours)

Patients experiencing any of these should seek prompt medical evaluation.

Serious

• Severe hypotension (systolic < 90 mm Hg) especially when combined with nitrates or alpha‑blockers
• Myocardial infarction or stroke in patients with pre‑existing cardiovascular disease
• Anaphylaxis or severe allergic reaction (rash, swelling, difficulty breathing)

Any serious adverse event warrants immediate emergency care.

Clinically Relevant Drug Interactions

• Nitrates (e.g., glyceryl trinitrate, isosorbide dinitrate) – additive vasodilation → life‑threatening hypotension.
• Alpha‑blockers (e.g., tamsulosin, doxazosin) – may cause symptomatic hypotension; dose titration recommended.
• CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) – increase tadalafil plasma concentrations → higher risk of side effects.
• CYP3A4 inducers (e.g., rifampin, carbamazepine) – decrease tadalafil exposure → reduced efficacy.

Patients should disclose all medications, including over‑the‑counter supplements, to their healthcare provider before initiating tadalafil.

Practical Use: Dosing, Missed Dose, Overdose

• Erectile Dysfunction (as‑needed) – Initiate with 10 mg taken prior to anticipated sexual activity. If tolerated, dose may be increased to 20 mg or decreased to 5 mg based on efficacy and side‑effect profile. Do not exceed one dose per 24 hours.
• PAH (once daily) – Recommended dose is 40 mg taken at the same time each day. Dose adjustments are made by the treating specialist according to clinical response and tolerability.
• BPH (off‑label) – 5 mg daily, taken at the same time each day.

Missed dose: For once‑daily regimens, take the missed dose 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. Do not double‑dose.

Overdose: Symptoms may include severe hypotension, prolonged erection, or intense headache. Patients should seek immediate medical attention. Supportive care (intravenous fluids, blood pressure monitoring) is the mainstay of treatment; there is no specific antidote.

Precautions:

• Avoid excessive alcohol, which can exacerbate hypotension and dizziness.
• High‑fat meals may delay onset but do not significantly affect overall exposure.
• Renal or hepatic impairment may require dose reduction; consult a physician.

FAQ

• Is Tadalafil available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name product is marketed as Cialis for erectile dysfunction and Adcirca for pulmonary arterial hypertension. Generic tadalafil, which contains the identical active ingredient, is also approved and can be purchased at a lower price through our online pharmacy.

• Does Tadalafil require refrigeration or special storage conditions?
  No. Tadalafil tablets should be stored at controlled room temperature (15 °C–30 °C), protected from moisture, heat, and direct sunlight. Keeping the medication in a dry cabinet or a closed drawer is sufficient.

• What do the tablets look like, and how can I identify the strength?
  Generic tadalafil tablets are film‑coated and typically oval or round. The imprint, color, and size vary by manufacturer, but most follow the pattern:

  • 2.5 mg – light pink, “2.5” imprint
  • 5 mg – white, “5” imprint
  • 10 mg – yellow, “10” imprint
  • 20 mg – blue, “20” imprint
    Always verify the packaging and label before use.

• Can I travel internationally with Tadalafil in my carry‑on luggage?
  Yes, provided the medication is in its original packaging with a clear label stating the generic name, strength, and quantity. For journeys longer than 30 days, carry a copy of the prescription or a physician’s letter, as some customs authorities may request documentation.

• Are there differences in formulation between Asian and Western markets?
  The core active ingredient, tadalafil, is identical worldwide. In some regions, manufacturers may use different inert excipients (e.g., lactose, microcrystalline cellulose) to comply with local regulatory standards. These differences do not affect therapeutic efficacy but may be relevant for patients with specific allergies.

• Will Tadalafil affect routine drug testing for employment or sports?
  Tadalafil is not a prohibited substance on standard occupational drug‑screening panels, nor is it listed by the World Anti‑Doping Agency (WADA) as a doping agent. However, athletes should verify sport‑specific regulations, as some organizations may have additional rules.

• How long does it take for the medication to be cleared from the body?
  The elimination half‑life of tadalafil is about 17.5 hours; therefore, 90 % of the dose is eliminated within 3–4 days. Renal and hepatic function can modestly prolong clearance, necessitating dose adjustment in severe impairment.

• Can Tadalafil be taken with other PDE5 inhibitors?
  No. Combining tadalafil with another PDE5 inhibitor (e.g., sildenafil, vardenafil) markedly increases the risk of hypotension, vision changes, and priapism. Only one PDE5 inhibitor should be used at a time, under medical supervision.

• Is there any evidence that Tadalafil improves cardiovascular health beyond PAH?
  Some studies have explored low‑dose tadalafil (2.5 mg or 5 mg daily) for endothelial function and exercise capacity in patients with heart failure with reduced ejection fraction. Results show modest improvements in walking distance, but the data are not yet sufficient for formal guideline endorsement.

• What should I do if I experience a painful erection lasting more than 4 hours?
  This condition, known as priapism, is a medical emergency. Seek immediate care at an emergency department; prompt treatment reduces the risk of permanent penile tissue damage.
