3CONTRAINDICATIONS
Dutasteride and tamsulosin hydrochloride capsules are contraindicated for use in:
- Pregnancy. Dutasteride use is contraindicated in females who are pregnant. In animal reproduction and developmental toxicity studies, dutasteride inhibited development of male fetus external genitalia. Therefore, dutasteride and tamsulosin hydrochloride capsules may cause fetal harm when administered to a pregnant female.
- Patients with previously demonstrated, clinically significant hypersensitivity (e.g., serious skin reactions, angioedema, urticaria, pruritus, respiratory symptoms) to dutasteride, other 5-alpha-reductase inhibitors, tamsulosin, or any other component of dutasteride and tamsulosin hydrochloride capsules
4DRUG INTERACTIONS
There have been no drug interaction trials using dutasteride and tamsulosin hydrochloride capsules. The following sections reflect information available for the individual components.
4.1Cytochrome P450 Inhibition
Dutasteride
Dutasteride is extensively metabolized in humans by the CYP3A4 and CYP3A5 isoenzymes. The effect of potent CYP3A4 inhibitors on dutasteride has not been studied. Because of the potential for drug-drug interactions, use caution when prescribing a dutasteride-containing product, including dutasteride and tamsulosin hydrochloride capsules, to patients taking potent, chronic CYP3A4 enzyme inhibitors (e.g., ritonavir) [seeClinical Pharmacology ( ].
Tamsulosin
Strong and Moderate Inhibitors of CYP3A4 or CYP2D6:Tamsulosin is extensively metabolized, mainly by CYP3A4 or CYP2D6.
Concomitant treatment with ketoconazole (a strong inhibitor of CYP3A4) resulted in increases in the C
Cimetidine: Treatment with cimetidine resulted in a moderate increase in tamsulosin hydrochloride AUC (44%) [seeWarnings and Precautions ( ].
4.2Warfarin
Dutasteride
Concomitant administration of dutasteride 0.5 mg/day for 3 weeks with warfarin does not alter the steady-state pharmacokinetics of the S- or R-warfarin isomers or alter the effect of warfarin on prothrombin time [seeClinical Pharmacology ( ].
Tamsulosin
A definitive drug-drug interaction trial between tamsulosin hydrochloride and warfarin was not conducted. Results from limited in vitroand in vivostudies are inconclusive. Caution should be exercised with concomitant administration of warfarin and tamsulosin-containing products, including dutasteride and tamsulosin hydrochloride capsules [seeWarnings and Precautions ( ].
4.3Nifedipine, Atenolol, Enalapril
Tamsulosin
Dosage adjustments are not necessary when tamsulosin is administered concomitantly with nifedipine, atenolol, or enalapril
4.4Digoxin and Theophylline
Dutasteride
Dutasteride does not alter the steady-state pharmacokinetics of digoxin when administered concomitantly at a dose of 0.5 mg/day for 3 weeks [seeClinical Pharmacology ( )].
Tamsulosin
Dosage adjustments are not necessary when tamsulosin is administered concomitantly with digoxin or theophylline [seeClinical Pharmacology ( ].
4.5Furosemide
Tamsulosin
Tamsulosin had no effect on the pharmacodynamics (excretion of electrolytes) of furosemide. While furosemide produced an 11% to 12% reduction in tamsulosin hydrochloride C maxand AUC, these changes are expected to be clinically insignificant and do not require adjustment of the dose of tamsulosin [seeClinical Pharmacology ( ].
4.6Calcium Channel Antagonists
Dutasteride
Coadministration of verapamil or diltiazem decreases dutasteride clearance and leads to increased exposure to dutasteride. The change in dutasteride exposure is not considered to be clinically significant. No dosage adjustment of dutasteride is recommended [seeClinical Pharmacology ( ].
4.7Cholestyramine
Dutasteride
Administration of a single 5 mg dose of dutasteride followed 1 hour later by a 12 g dose of cholestyramine does not affect the relative bioavailability of dutasteride [seeClinical Pharmacology ( ].
5OVERDOSAGE
No data are available with regard to overdosage with dutasteride and tamsulosin hydrochloride capsules. The following text reflects information available for the individual components.
Dutasteride
In volunteer trials, single doses of dutasteride up to 40 mg (80 times the therapeutic dose) for 7 days have been administered without significant safety concerns. In a clinical trial, daily doses of 5 mg (10 times the therapeutic dose) were administered to 60 subjects for 6 months with no additional adverse effects to those seen at therapeutic doses of 0.5 mg.
There is no specific antidote for dutasteride. Therefore, in cases of suspected overdosage symptomatic and supportive treatment should be given as appropriate, taking the long half-life of dutasteride into consideration.
Tamsulosin
Should overdosage of tamsulosin lead to hypotension [seeWarnings and Precautions ( ], support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by keeping the patient in the supine position. If this measure is inadequate, then administration of intravenous fluids should be considered. If necessary, vasopressors should then be used and renal function should be monitored and supported as needed. Laboratory data indicate that tamsulosin is 94% to 99% protein bound; therefore, dialysis is unlikely to be of benefit.

7CLINICAL STUDIES
The trial supporting the efficacy of dutasteride and tamsulosin hydrochloride capsules was a 4-year multicenter, randomized, double-blind, parallel-group trial (CombAT trial) investigating the efficacy of the coadministration of dutasteride 0.5 mg/day and tamsulosin hydrochloride 0.4 mg/day (n = 1,610) compared with dutasteride alone (n = 1,623) or tamsulosin alone (n = 1,611). Subjects were aged at least 50 years with a serum PSA ≥1.5 ng/mL and <10 ng/mL and BPH diagnosed by medical history and physical examination, including enlarged prostate (≥30 cc) and BPH symptoms that were moderate to severe according to the International Prostate Symptom Score (IPSS). Eighty-eight percent (88%) of the enrolled trial population was white. Approximately 52% of subjects had previous exposure to 5-alpha-reductase inhibitor or alpha-adrenergic antagonist treatment. Of the 4,844 subjects randomly assigned to receive treatment, 69% of subjects in the coadministration group, 67% in the dutasteride group, and 61% in the tamsulosin group completed 4 years of double-blind treatment.
Effect on Symptom Score
Symptoms were quantified using the first 7 questions of the International Prostate Symptom Score (IPSS). The baseline score was approximately 16.4 units for each treatment group. Coadministration therapy was statistically superior to each of the monotherapy treatments in decreasing symptom score at Month 24, the primary time point for this endpoint. At Month 24, the mean changes from baseline (±SD) in IPSS total symptom scores were -6.2 (±7.14) for the coadministration group, -4.9 (±6.81) for dutasteride, and -4.3 (±7.01) for tamsulosin, with a mean difference between coadministration and dutasteride of -1.3 units ( P<0.001; [95% CI: -1.69, -0.86]), and between coadministration and tamsulosin of -1.8 units ( P<0.001; [95% CI: -2.23, -1.40]). A significant difference was seen by Month 9 and continued through Month 48. At Month 48 the mean changes from baseline (±SD) in IPSS total symptom scores were -6.3 (±7.40) for coadministration, -5.3 (±7.14) for dutasteride, and -3.8 (±7.74) for tamsulosin, with a mean difference between coadministration and dutasteride of -0.96 units ( P<0.001; [95% CI: -1.40, -0.52]), and between coadministration and tamsulosin of -2.5 units ( P<0.001; [95% CI: -2.96, -2.07]). See Figure 1.
Figure 1. International Prostate Symptom Score Change from Baseline over a 48-MonthPeriod (Randomized, Double-blind, Parallel-group Trial [CombAT Trial])
Effect on Acute Urinary Retention (AUR) or the Need for BPH-Related Surgery
After 4 years of treatment, coadministration therapy with dutasteride and tamsulosin did not provide benefit over dutasteride monotherapy in reducing the incidence of AUR or BPH-related surgery.
In separate 2-year randomized, double-blind trials, compared with placebo, dutasteride monotherapy was associated with a statistically significantly lower incidence of AUR (1.8% for dutasteride versus 4.2% for placebo; 57% reduction in risk) and with a statistically significantly lower incidence of BPH-related surgery (2.2% for dutasteride versus. 4.1% for placebo; 48% reduction in risk).

Effect on Prostate Volume
The mean prostate volume at trial entry was approximately 55 cc. At Month 24, the primary time point for this endpoint, the mean percent changes from baseline (±SD) in prostate volume were -26.9% (±22.57) for coadministration therapy, -28.0% (±24.88) for dutasteride, and 0% (±31.14) for tamsulosin, with a mean difference between coadministration and dutasteride of 1.1% (

What are dutasteride and tamsulosin hydrochloride capsules?
Dutasteride and tamsulosin hydrochloride capsules are a prescription medicine that contains 2 medicines: dutasteride and tamsulosin. Dutasteride and tamsulosin hydrochloride capsules are used to treat the symptoms of benign prostatic hyperplasia (BPH) in men with an enlarged prostate. The 2 medications in dutasteride and tamsulosin hydrochloride capsules work in different ways to improve symptoms of BPH. Dutasteride shrinks the enlarged prostate and tamsulosin relaxes muscles in the prostate and neck of the bladder. These 2 medications, when used together, can improve symptoms of BPH better than either medication when used alone.
