Waarschuwingen en voorzorgen

• Orthostatic hypotension and/or syncope can occur. Advise patients of symptoms related to postural hypotension and to avoid situations where injury could result if syncope occurs.
• Do not use dutasteride and tamsulosin hydrochloride with other alpha-adrenergic antagonists, as this may increase the risk of hypotension.
• Dutasteride and tamsulosin hydrochloride reduces serum prostate-specific antigen (PSA) concentration by approximately 50%.

• Do not use dutasteride and tamsulosin hydrochloride with strong inhibitors of cytochrome P450 (CYP) 3A4 (e.g., ketoconazole). Use caution in combination with moderate CYP3A4 inhibitors (e.g., erythromycin) or strong (e.g., paroxetine) or moderate CYP2D6 inhibitors, a combination of both CYP3A4 and CYP2D6 inhibitors, or known poor metabolizers of CYP2D6.
• Exercise caution with concomitant use of phosphodiesterase-5 (PDE-5) inhibitors, as this may increase the risk of hypotension.
• Drugs that contain dutasteride, including dutasteride and tamsulosin hydrochloride, may increase the risk of high-grade prostate cancer.
• Prior to initiating treatment with dutasteride and tamsulosin hydrochloride, consideration should be given to other urological conditions that may cause similar symptoms.

Zwangerschap

Dutasteride and tamsulosin hydrochloride is contraindicated for use in pregnancy because it may cause harm to the male fetus. Dutasteride and tamsulosin hydrochloride is not indicated for use in females. Dutasteride, a component of dutasteride and tamsulosin hydrochloride, is a 5-alpha-reductase inhibitor that prevents conversion of testosterone to dihydrotestosterone (DHT), a hormone necessary for normal development of male genitalia.

Werkingsmechanisme

Dutasteride and tamsulosin hydrochloride are a combination of 2 drugs with different mechanisms of action to improve symptoms in patients with BPH: dutasteride, a 5-alpha-reductase inhibitor, and tamsulosin, an antagonist of alpha 1A -adrenoreceptors. Dutasteride Dutasteride inhibits the conversion of testosterone to DHT. DHT is the androgen primarily responsible for the initial development and subsequent enlargement of the prostate gland.
