Indications & Clinical Uses

Miktosan belongs to the alpha‑1 adrenergic antagonist class and is used to manage conditions related to prostate enlargement.

  • Benign prostatic hyperplasia (BPH): reduces prostate smooth‑muscle tone and improves urine flow.
  • Lower urinary tract symptoms (LUTS) associated with BPH: decreases urgency, frequency and nocturia.
  • Prostatic enlargement causing bladder outlet obstruction: facilitates bladder emptying.

How It Works

  • Tamsulosin selectively blocks alpha‑1A and alpha‑1D adrenergic receptors located in the prostate, bladder neck and urethra. This antagonism relaxes smooth‑muscle fibers in these tissues, decreasing urethral resistance and allowing a more efficient urinary stream without significantly affecting blood pressure.

Side Effects

Common Side Effects

  • Dizziness: transient light‑headedness, especially on standing.
  • Headache: mild to moderate intensity.
  • Abnormal ejaculation: reduced volume or retrograde flow.
  • Nasal congestion: stuffy or runny nose.
  • Orthostatic hypotension: drop in blood pressure upon standing.

Serious or Rare Side Effects

  • Priapism: prolonged painful erection requiring urgent care.
  • Severe hypotension: marked drop in blood pressure leading to fainting.
  • Allergic reactions: rash, itching, swelling, or anaphylaxis.
  • Angioedema: swelling of face, lips, tongue or throat.
  • Intraoperative floppy iris syndrome (IFIS): potential complication during cataract surgery.

Precautions & Warnings

Before initiating therapy, consider the following precautions.

  • Cardiovascular assessment: evaluate for orthostatic hypotension risk.
  • Blood pressure monitoring: check baseline and periodic readings.
  • Liver function: use with caution in patients with severe hepatic impairment.
  • Cataract surgery planning: inform ophthalmologists of tamsulosin use due to IFIS risk.
  • Elderly patients: start at the lowest effective dose and monitor closely.
  • Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Avoid Interactions

Tamsulosin may interact with several medicines.

Major Interactions (Avoid)

  • Potent CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase tamsulosin levels.
  • Other alpha‑blockers (e.g., prazosin): risk of severe hypotension.
  • Phosphodiesterase‑5 inhibitors (e.g., sildenafil): additive blood‑pressure lowering effect.

Moderate Interactions (Monitor Closely)

  • Diuretics: enhanced orthostatic hypotension.
  • Antihypertensive agents: possible additive blood‑pressure reduction.
  • CYP3A4 inducers (e.g., rifampicin): may reduce tamsulosin efficacy.

Frequently Asked Questions

Miktosan contains tamsulosin hydrochloride and is prescribed to men with benign prostatic hyperplasia (BPH) to relieve urinary obstruction. It improves urine flow and reduces symptoms such as urgency, frequency, and nighttime urination.

Tamsulosin selectively blocks alpha‑1A and alpha‑1D receptors in the prostate and bladder neck. This relaxes smooth‑muscle tone in those areas, decreasing urethral resistance and allowing a smoother, more complete bladder emptying.

The dosage of Miktosan is determined by the prescribing clinician based on the patient’s condition, age, renal and hepatic function, and response to therapy. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety of tamsulosin in pregnancy and lactation has not been established. It is generally not recommended for use in pregnant or nursing women because the potential risks to the fetus or infant are unknown.

To place an order, submit an enquiry on the 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 and any necessary import documentation.

Miktosan (tamsulosin) is an alpha‑1 blocker that provides rapid symptom relief by relaxing prostate smooth muscle. Compared with 5‑alpha‑reductase inhibitors such as finasteride, tamsulosin works faster but does not reduce prostate size. It is often used alone or in combination with other agents for comprehensive BPH management.

Miktosan tablets should be stored at ambient temperature, below 25 °C, in the original blister pack. Keep the product away from moisture, heat and direct sunlight to maintain stability.

Miktosan is taken orally, usually once daily, with or without food. The tablet should be swallowed whole with a glass of water and not chewed or crushed to ensure proper absorption.

Serious adverse events include priapism, severe hypotension, allergic reactions such as anaphylaxis, angioedema, and intra‑operative floppy iris syndrome (IFIS) which can complicate cataract surgery. Patients should seek immediate medical attention if any of these occur.

Miktosan is contraindicated in patients with known hypersensitivity to tamsulosin or any component of the formulation. It should be used with caution in individuals with severe liver impairment, those prone to orthostatic hypotension, and patients scheduled for cataract surgery due to the risk of IFIS.
