Indications & Clinical Uses

Tadalafil acts on the phosphodiesterase‑5 pathway to improve vascular smooth‑muscle tone in several disease states.

  • Erectile dysfunction: enhances the ability to achieve and maintain an erection when sexually stimulated.
  • Pulmonary arterial hypertension: lowers pulmonary arterial pressure and improves exercise capacity.
  • Benign prostatic hyperplasia: reduces urinary frequency and improves flow by relaxing smooth muscle in the prostate and bladder neck.

How It Works

  • Tadalafil selectively inhibits the enzyme phosphodiesterase type 5 (PDE5), preventing the breakdown of cyclic guanosine monophosphate (cGMP). Elevated cGMP levels lead to relaxation of smooth muscle in the corpus cavernosum and pulmonary vasculature, facilitating increased blood flow and improved erectile function or reduced pulmonary arterial pressure.

Side Effects

Adverse reactions may vary in frequency and severity.

Common Side Effects

  • Headache
  • Flushing
  • Dyspepsia
  • Nasal congestion

Serious or Rare Side Effects

  • Sudden vision loss (non‑arteritic anterior ischemic optic neuropathy)
  • Priapism lasting longer than 4 hours
  • Severe hypotension or syncope

Precautions & Warnings

Before prescribing, clinicians should consider several safety factors.

  • Cardiovascular assessment: evaluate underlying heart disease before use.
  • Concomitant nitrate therapy: contraindicated due to risk of profound hypotension.
  • Severe renal or hepatic impairment: dose adjustment may be required.
  • Uncontrolled hypertension or hypotension: monitor blood pressure closely.
  • Retinitis pigmentosa or other retinal disorders: avoid use.
  • Store at ambient temperature: keep in the original pack, protect from moisture.

Avoid Interactions

Tadalafil can interact with several medication classes.

Major Interactions (Avoid)

  • Nitrates (e.g., nitroglycerin, isosorbide dinitrate)
  • Guanylate cyclase stimulators (e.g., riociguat)
  • Certain alpha‑blockers (e.g., doxazosin) in high doses

Moderate Interactions (Monitor Closely)

  • Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin)
  • CYP3A4 inducers (e.g., rifampin, carbamazepine)
  • Antihypertensive agents (e.g., beta‑blockers, calcium channel blockers)
  • Alcohol: may enhance hypotensive effect

Frequently Asked Questions

Nairem contains tadalafil, which is prescribed for erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia. In each case the drug works by relaxing smooth muscle to improve blood flow or reduce urinary obstruction, helping patients achieve better sexual function, lower pulmonary pressures, or relieve urinary symptoms.

Tadalafil selectively blocks the phosphodiesterase‑5 enzyme, which normally degrades cyclic guanosine monophosphate (cGMP). By preserving cGMP, tadalafil promotes smooth‑muscle relaxation in the corpus cavernosum and pulmonary vessels, increasing blood flow to the penis or lowering pressure in the lungs, depending on the indication.

The appropriate dose of Nairem is determined by a qualified prescriber based on the specific indication, patient health status, and any concomitant medications. Healthcare professionals tailor the regimen to achieve therapeutic benefit while minimizing risk, and patients should follow the prescribed instructions exactly.

Tadalafil is not recommended for use in pregnancy or while breastfeeding because safety data are limited. Women who are pregnant, planning to become pregnant, or nursing should avoid the medication unless a healthcare provider determines that the potential benefits outweigh the risks.

To place an order, submit an enquiry on the Nairem product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements), and necessary import documentation.

Nairem (tadalafil) has a longer half‑life than sildenafil or vardenafil, allowing once‑daily dosing for conditions like benign prostatic hyperplasia or flexible timing for erectile dysfunction. Its duration of action can extend up to 36 hours, whereas other PDE5 inhibitors typically last 4–12 hours. Choice of agent depends on patient preference, dosing schedule, and clinical considerations.

Nairem should be stored at ambient temperature, below 25 °C (77 °F). Keep the tablets in the original container, protect them from moisture and direct sunlight, and ensure the package remains tightly closed until use to maintain product stability.

Nairem is taken orally, usually with water. The tablet can be swallowed with or without food, although a high‑fat meal may delay absorption slightly. Patients should follow the dosing schedule prescribed by their healthcare provider and avoid taking more than the recommended amount.

Serious risks include sudden vision loss (non‑arteritic anterior ischemic optic neuropathy), prolonged erections lasting more than four hours (priapism), and severe hypotension, especially when combined with nitrates or certain antihypertensives. Patients experiencing any of these symptoms should seek immediate medical attention.

Nairem is contraindicated in individuals taking nitrates, those with severe uncontrolled hypertension or hypotension, patients with a known hypersensitivity to tadalafil, and persons with certain rare eye disorders such as retinitis pigmentosa. Clinicians should also exercise caution in patients with significant cardiovascular disease, liver or kidney impairment.
