Tamsulosin is an antagonist of α1A-adrenoreceptors in the prostate. It binds selectively and competitively to postsynaptic α1A-adrenoreceptors, which convey smooth muscle contraction, thereby relaxing prostatic and urethral smooth muscle.
Prostam Capsule 0.4 mg
The recommended dose of Tamsulosin is 0.4 mg once daily. It should be administered approximately half/hour following the same meal each day. For those patients who fail to respond to the 0.4 mg dose after two to four weeks of dosing, the dose of Tamsulosin can be increased to 0.8mg once daily. If Tamsulosin administration is discontinued or interrupted for several days at either the 0.4 mg or 0.8 mg dose, therapy should be started again with the 0.4 mg once daily dose.
