Miktosan (Tamsulosin Hydrochloride)

Tamsulosin Hydrochloride, the active ingredient in Miktosan, is an alpha-1 adrenergic receptor antagonist presented as an oral tablet for oral use. It is indicated for the treatment of benign prostatic hyperplasia and associated lower urinary tract symptoms in adult men. GNH USA supplies Miktosan as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

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.

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.

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.

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.
