Combodart Efficacy

Combodart is indicated for the management of moderate to severe symptomatic benign prostatic hyperplasia (BPH).

Achieving sustained symptom relief and prevention of disease progression with medical therapy?
(as measured by reductions in acute urinary retention and need for BPH-related surgery)

The table belows explains how the two medicines combined in Combodart, dutasteride (5ARI) and
tamsulosin hydrochloride (α-blocker), work together to affect BPH symptoms and slows disease progression therefore reducing long-term complications in a patient.

    including Benign Prostatic Obstruction (BPO). European Association of Urology, 2012.

Combodart offers superior and sustained symptom improvement at 4 years vs both tamsulosin and dutasteride monotherapy

Mean adjusted change in International Prostate Symptom Score (IPSS) from baseline by visit and treatment group

Combodarts’s symptom improvement is superior vs tamsulosin from 9 months.

Patients in CombAT presented with moderate symptoms and had prostate volume ≥ 30cm3. Data based on dutasteride and tamsulosin free combination. Bioequivalence has been demonstrated with Combodart. Secondary Endpoint.

Combodart significantly reduces the risk of AUR and BPH-related surgery Relative Risk Reduction vs tamsulosin at 4 years

Absolute Risk Reduction (AAR) 8%

AUR = acute urinary retention

*No significant difference was seen between dutasteride and tamsulosin (Combodart) therapy vs dutasteride alone (19.6% RRR, p=0.18).

Combodart reduces prostate volume and decreases PSA* in BPH patients [1],[2]

*the reduction in mean serum PSA by approximately 50% after six months of treatment. [1]
PSA levels in BPH patient receiving Combodart (schematic representation) [1],[2],[3]

  • Combodart reduces prostate volume and, therefore, causes a decrease in serum PSA levels by approximately 50% after 6 months in patients with BPH [1],[2],[3]
  • Patients receiving Combodart should have a new PSA baseline established after 6 months of treatment [1]
  • It is recommended to monitor PSA values regularly thereafter [1]
  • Any confirmed increase from lowest PSA level while on Combodart should be carefully evaluated as it may signal the presence of prostate cancer or non-compliance to therapy with Combodart [1]
