Omnic Ocas 0.4mg is a prescription medication containing Tamsulosin HCl, used to treat symptoms of benign prostatic hyperplasia (BPH). Each pack contains 30 tablets in a controlled release formulation designed for once-daily dosing. The active ingredient Tamsulosin belongs to a class of medications called alpha-blockers. It works by relaxing muscles in the prostate and bladder neck, making it easier to urinate. The OCAS (Oral Controlled Absorption System) technology provides steady drug release over 24 hours. The tablets should be taken once daily at the same time with or without food. This medication requires a prescription and should be taken under medical supervision.
