Furosemide
The pharmacokinetic and pharmacodynamic interaction between Flomax(tamsulosin hydrochloride) capsules 0.8 mg/day (steady-state) and furosemide 20 mg intravenously (single dose) was evaluated in ten healthy volunteers (age range 21-40 years). FLOMAX capsules had no effect on the pharmacodynamics (excretion of electrolytes) of furosemide. While furosemide produced an 11% to 12% reduction in tamsulosin hydrochloride Cmax and AUC, these changes are expected to be clinically insignificant and do not require adjustment of the FLOMAX capsules dosage.

Cytochrome P450 Inhibition:
Cimetidine
The effects of cimetidine at the highest recommended dose (400 mg every six hours for six days) on the pharmacokinetics of a single FLOMAX capsule 0.4 mg dose was investigated in ten healthy volunteers (age range 21-38 years). Treatment with cimetidine resulted in a significant decrease (26%) in the clearance of tamsulosin hydrochloride, which resulted in a moderate increase in tamsulosin hydrochloride AUC (44%). Therefore, FLOMAX capsules should be used with caution in combination with cimetidine, particularly at doses higher than 0.4 mg.
Strong Inhibitors of CYP3A4 or CYP2D6
The effects of ketoconazole (a strong inhibitor of CYP3A4) at 400 mg every day on the pharmacokinetics of a single FLOMAX capsule 0.4 mg dose was investigated in 24 healthy volunteers (age range from 23 to 47 years). Treatment with ketoconazole resulted in a Cmax and AUC that increased by a factor of 2.2 and 2.8, respectively. Therefore, FLOMAX 0.4 mg capsules should be used with caution in combination with strong inhibitors of CYP3A4. Doses above 0.4 mg should not be used in combination with strong inhibitors of CYP3A4 (e.g., ketoconazole).
The effects of paroxetine (a strong inhibitor of CYP2D6) at 20 mg every day on the pharmacokinetics of a single FLOMAX capsule 0.4 mg dose was investigated in 23 healthy volunteers (age range from 23 to 48 years). Treatment with paroxetine resulted in a Cmax and AUC that increased by a factor of 1.3 and 1.6, respectively. Therefore, FLOMAX capsules should be used with caution in combination with strong inhibitors of CYP2D6, particularly at doses higher than 0.4 mg (e.g., 0.8 mg).
