Reporting Groups
  Description
Tamsulosin - Low Dose Level (PK Study)

Subjects randomized to low dose level (0.001–0.002 mg/kg) of tamsulosin hydrochloride, dependent on a subject's body weight.

In PK study, all subjects were titrated to their randomized dose level that they needed to receive which was based on their weight. Depending on the results of the Leak point pressure (LPP) results, subjects could remain on that dose if it was found to be efficacious or go back to a lower efficacious dose or titrate up in hopes that the higher dose would provide some efficacy.

Subjects with body weight of 12.1-25.0 kg received low dose of 0.025 mg qd (once daily), body weight of 25.1–50.0 kg received low dose of 0.05 mg qd and body weight of 50.1–100.0 kg received low dose of 0.1 mg qd by sprinkling the content of the capsule(s) over teaspoon of apple sauce or yogurt taken 30 minutes after breakfast.

In PK study, all subjects were titrated to their randomized dose level that they needed to receive which was based on their weight. Depending on the results of the LPP results, subjects could remain on that dose if it was found to be efficacious or go back to a lower efficacious dose or titrate up in hopes that the higher dose would provide some efficacy.
