Indications & Clinical Uses

Omnic Ocas contains tamsulosin, an alpha‑1 blocker that relaxes smooth muscle in the urinary tract. It is indicated for:

  • Benign prostatic hyperplasia (BPH): reduces urinary obstruction and improves urine flow.
  • Pre‑surgical management of BPH: helps lower the risk of intra‑operative bleeding.
  • Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) adjunct: may relieve lower urinary tract symptoms when used with other therapies.

How It Works

  • Tamsulosin selectively blocks alpha‑1A adrenergic receptors located in the prostate, bladder neck and urethra. By inhibiting these receptors, it reduces smooth‑muscle tone, leading to decreased resistance to urinary flow and relief of lower urinary tract symptoms associated with BPH.
