Precautions
Hypersensitivity to Tamsulosin Hydrochloride. A history of orthostatic hypotension; severe hepatic insufficiency. As with other alpha1 blockers, a reduction in blood pressure can occur in individual cases during treatment with Tamsulosin, as a result of which, rarely, syncope can occur. At the first signs of orthostatic hypotension (dizziness, weakness) the patient should sit or lie down until the symptoms have disappeared. And they should be cautioned to avoid situations where injury could result (like driving, operating machinery or performing hazardous tasks).
Before therapy with Tamsulosin is initiated the patient should be examined in order to exclude the presence of other conditions which can cause the same symptoms as Benign Prostatic Hyperplasia. Digital rectal examination and when necessary determination of Prostate Specific Antigen (PSA) should be performed before treatment and at regular intervals afterwards. The treatment of severely renal impaired patients (creatinine clearance is less than10ml/min) should be approached with caution as these patients have not been studied. Caution should be exercised in porphyria or allergic reaction to this or any other medicine.
Pregnancy-Lactation
Interactions
Increased plasma concentration w/ strong CYP3A4 inhibitors (e.g. ketoconazole). Moderate CYP3A4 inhibitors (e.g. erythromycin), strong (e.g. paroxetine) or moderate (e.g. terbinafine) CYP2D6 inhibitors may increase exposure of tamsulosin. Increased plasma concentration w/ cimetidine. Additive effect w/ other ?-adrenergic blocking agents. Concomitant use w/ PDE5 inhibitors may lead to symptomatic hypotension. Decreased plasma concentration w/ furosemide.

Mechanism of Action
Tamsulosin is a selective alpha1 adrenoreceptor-blocking agent. Smooth muscle tone is mediated by the sympathetic nervous stimulation of alpha1 adrenoreceptors, which are abundant in the prostate, prostatic capsule, prostatic urethra, and bladder neck. Blockade of these adrenoceptors can cause smooth muscles in the bladder neck and prostate to relax, resulting in an improvement in urine flow rate and reduction in symptoms in BPH.
