The Impact of Long-Term Dutasteride Use on Surgical Outcomes and Perioperative Parameters in Patients Undergoing Holmium Laser Enucleation of the Prostate (HoLEP)
Summary: This study aims to investigate the effects of long-term dutasteride use (a 5-alpha reductase inhibitor) on surgical outcomes in patients undergoing Holmium Laser Enucleation of the Prostate (HoLEP) for benign prostatic hyperplasia (BPH). While some studies suggest that short-term use of these medications can reduce bleeding during surgery, there is limited data on the impact of chronic, long-term ...
A Phase II Prospective Single-arm Study of Dutasteride in Patients With Low Grade Non-muscle Invasive Bladder Cancer
Summary: Low grade non-muscle-invasive bladder cancer (NMIBC) often recurs after treatment, requiring repeated surgeries, especially in older patients. These recurrences can cause complications, reduce quality of life, and increase healthcare costs. Currently, there is no well-tolerated preventive treatment routinely used for patients with low-risk disease. This study will evaluate whether dutasteride, an ...

Summary: This study is a double blinded RCT with pre-post test design on the effect of combination of dutasteride and aloe vera, compared to dutasteride only, on uroflowmetry results, prostate volume, and VEGF serum level among patients with benign prostate hyperplasia. The treatment was given for 12 weeks

Brand Information
AVODART (dutasteride)
1DOSAGE AND ADMINISTRATION
The capsules should be swallowed whole and not chewed or opened, as contact with the capsule contents may result in irritation of the oropharyngeal mucosa. AVODART may be administered with or without food.
1.1Monotherapy
The recommended dose of AVODART is 1 capsule (0.5 mg) taken once daily.
1.2Combination with Alpha-adrenergic Antagonist
The recommended dose of AVODART is 1 capsule (0.5 mg) taken once daily and tamsulosin 0.4 mg taken once daily.
2DOSAGE FORMS AND STRENGTHS
0.5-mg, opaque, dull yellow, gelatin capsules imprinted with “GX CE2” in red ink on one side.
3CONTRAINDICATIONS
AVODART is contraindicated for use in:
- Pregnancy. Dutasteride use is contraindicated in women who are pregnant. In animal reproduction and developmental toxicity studies, dutasteride inhibited development of male fetus external genitalia. Therefore, AVODART may cause fetal harm when administered to a pregnant woman
- Patients with previously demonstrated clinically significant hypersensitivity (e.g., serious skin reactions, angioedema) to AVODART or other 5 alpha-reductase inhibitors
4OVERDOSAGE
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.
5DESCRIPTION
AVODART is a synthetic 4-azasteroid compound that is a selective inhibitor of both the type 1 and type 2 isoforms of steroid 5 alpha-reductase, an intracellular enzyme that converts testosterone to DHT.
Dutasteride is chemically designated as (5α,17β)-N-{2,5 bis(trifluoromethyl)phenyl}-3-oxo-4-azaandrost-1-ene-17-carboxamide. The empirical formula of dutasteride is C
Dutasteride is a white to pale yellow powder with a melting point of 242° to 250°C. It is soluble in ethanol (44 mg/mL), methanol (64 mg/mL), and polyethylene glycol 400 (3 mg/mL), but it is insoluble in water.
Each AVODART soft gelatin capsule, administered orally, contains 0.5 mg of dutasteride dissolved in a mixture of mono-di-glycerides of caprylic/capric acid and butylated hydroxytoluene. The inactive excipients in the capsule shell are ferric oxide (yellow), gelatin (from certified BSE-free bovine sources), glycerin, and titanium dioxide. The soft gelatin capsules are printed with edible red ink.
6HOW SUPPLIED/STORAGE AND HANDLING
AVODART soft gelatin capsules 0.5 mg are oblong, opaque, dull yellow, gelatin capsules imprinted with “GX CE2” with red edible ink on one side, packaged in bottles of 30 (NDC 80725-712-15) and 90 (NDC 80725-712-04) with child-resistant closures.
Store at 25°C (77°F); excursions permitted to 15° to 30°C (59° to 86°F) [see USP Controlled Room Temperature].
Dutasteride is absorbed through the skin. AVODART capsules should not be handled by women who are pregnant or who could become pregnant because of the potential for absorption of dutasteride and the subsequent potential risk to a developing male fetus
7PATIENT COUNSELING INFORMATION
Advise the patient to read the FDA-approved patient labeling (Patient Information).
PSA Monitoring
Inform patients that AVODART reduces serum PSA levels by approximately 50% within 3 to 6 months of therapy, although it may vary for each individual. For patients undergoing PSA screening, increases in PSA levels while on treatment with AVODART may signal the presence of prostate cancer and should be evaluated by a healthcare provider
Increased Risk of High-grade Prostate Cancer
Inform patients that there was an increase in high-grade prostate cancer in men treated with 5 alpha-reductase inhibitors (which are indicated for BPH treatment), including AVODART, compared with those treated with placebo in trials looking at the use of these drugs to reduce the risk of prostate cancer
Transdermal Exposure of AVODART in Pregnant or Potentially Pregnant Women—Risk to Male Fetus
Inform patients that AVODART capsules should not be handled by women who are pregnant or may potentially be pregnant because of the potential for absorption of dutasteride and the subsequent potential risk to a developing male fetus. Dutasteride can be absorbed through the skin and could result in unintended fetal exposure. If a pregnant or potentially pregnant woman comes in contact with leaking AVODART capsules, the contact area should be washed immediately with soap and water
Effects on Semen Parameters
Advise men that AVODART may affect sperm characteristics but the effect on fertility is unknown
Blood Donation
Inform men treated with AVODART that they should not donate blood until at least 6 months following their last dose to prevent pregnant women from receiving dutasteride through blood transfusion
