Omsal (Tamsulosin Hydrochloride)

Tamsulosin Hydrochloride, the active ingredient in Omsal, is an alpha‑1 adrenergic antagonist presented as a tablet for oral use. It relaxes smooth muscle in the prostate and bladder neck to improve urine flow in men with benign prostatic hyperplasia.

GNH USA supplies Omsal as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Tamsulosin Hydrochloride is used to treat conditions that involve urinary outflow obstruction related to the prostate.

- Benign prostatic hyperplasia (BPH): reduces urinary frequency, urgency and nocturia while improving urine stream. - Lower urinary tract symptoms (LUTS) associated with BPH: alleviates difficulty initiating urination and weak stream. - Pre‑surgical preparation for transurethral resection of the prostate (TUR‑P): helps stabilize bladder pressure before surgery.

Tamsulosin may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Dizziness or light‑headedness, especially on standing. - Abnormal ejaculation, such as reduced volume or retrograde flow. - Nasal congestion or runny nose. - Headache. - Fatigue.

Serious or Rare Side Effects: - Persistent low blood pressure (orthostatic hypotension). - Severe allergic reaction (anaphylaxis, rash, swelling). - Priapism (prolonged erection).

Before initiating therapy, clinicians should evaluate patient history and comorbidities.

- Cardiovascular assessment: monitor for orthostatic hypotension, especially in patients on antihypertensives. - Liver function: dose adjustment may be needed in severe hepatic impairment. - Concomitant alpha‑blockers: avoid additive blood‑pressure effects. - Surgery: inform surgical team, as intra‑operative hypotension may occur. - Storage: Store below 25°C: keep in the original pack, protect from moisture.

Tamsulosin can interact with several drug classes, altering its efficacy or safety profile.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin): may increase tamsulosin plasma levels. - Phosphodiesterase‑5 inhibitors (e.g., sildenafil): heightened risk of hypotension.

Moderate Interactions (Monitor Closely): - Antihypertensive agents: additive blood‑pressure lowering effect. - Diuretics: may exacerbate orthostatic dizziness. - Other alpha‑blockers: increased risk of severe hypotension.
