FINASTERIDE- finasteride tablet, film coated
Finasteride tablets 5 mg are indicated for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate to:
-Reduce the risk of acute urinary retention -Reduce the risk of the need for surgery including transurethral resection of the prostate (TURP) and prostatectomy.
Finasteride tablets 5 mg administered in combination with the alpha-blocker doxazosin is indicated to reduce the risk of symptomatic progression of BPH (a confirmed ≥4 point increase in American Urological Association (AUA) symptom score).
Finasteride is not approved for the prevention of prostate cancer.
Finasteride tablets 5 mg may be administered with or without meals.
The recommended dose of finasteride tablets 5 mg is one tablet (5 mg) taken once a day [see Clinical Studies (14.1)] .
The recommended dose of finasteride tablets 5 mg is one tablet (5 mg) taken once a day in combination with the alpha-blocker doxazosin [see Clinical Studies (14.2)] .
5-mg blue, 7 mm, round, biconvex, film coated tablets, marked ‘F5’ on one side and plain on other side.
Finasteride is contraindicated in the following:
- Hypersensitivity to any component of this medication.
- Pregnancy. Finasteride use is contraindicated in females when they are or may potentially be pregnant. Because of the ability of Type II 5α-reductase inhibitors to inhibit the conversion of testosterone to 5α-dihydrotestosterone (DHT), finasteride may cause abnormalities of the external genitalia of a male fetus of a pregnant female who receives finasteride. If this drug is used during pregnancy, or if pregnancy occurs while taking this drug, the pregnant female should be apprised of the potential hazard to the male fetus. [See also Warnings and Precautions (5.3), Use in Specific Populations (8.1),and How Supplied/Storage and Handling (16)]. In female rats, low doses of finasteride administered during pregnancy have produced abnormalities of the external genitalia in male offspring.
In clinical studies, finasteride reduced serum PSA concentration by approximately 50% within six months of treatment. This decrease is predictable over the entire range of PSA values in patients with symptomatic BPH, although it may vary in individuals.
For interpretation of serial PSAs in men taking finasteride, a new PSA baseline should be established at least six months after starting treatment and PSA monitored periodically thereafter. Any confirmed increase from the lowest PSA value while on finasteride may signal the presence of prostate cancer and should be evaluated, even if PSA levels are still within the normal range for men not taking a 5α-reductase inhibitor. Non-compliance with finasteride therapy may also affect PSA test results. To interpret an isolated PSA value in patients treated with finasteride for six months or more, PSA values should be doubled for comparison with normal ranges in untreated men. These adjustments preserve the utility of PSA to detect prostate cancer in men treated with finasteride.
Finasteride may also cause decreases in serum PSA in the presence of prostate cancer.
The ratio of free to total PSA (percent free PSA) remains constant even under the influence of finasteride. If clinicians elect to use percent free PSA as an aid in the detection of prostate cancer in men undergoing finasteride therapy, no adjustment to its value appears necessary.
Men aged 55 and over with a normal digital rectal examination and PSA ≤3.0 ng/mL at baseline taking finasteride 5 mg/day in the 7-year Prostate Cancer Prevention Trial (PCPT) had an increased risk of Gleason score 8 to 10 prostate cancer (finasteride 1.8% vs placebo 1.1%). [See Indications and Usage (1.3)and Adverse Reactions (6.1).] Similar results were observed in a 4-year placebo-controlled clinical trial with another 5α-reductase inhibitor (dutasteride, AVODART) (1% dutasteride vs 0.5% placebo). 5α-reductase inhibitors may increase the risk of development of high-grade prostate cancer. Whether the effect of 5α-reductase inhibitors to reduce prostate volume, or study-related factors, impacted the results of these studies has not been established.
Finasteride tablets are contraindicated in pregnant females and in females who may potentially be pregnant and not indicated for use in females. Based on animal studies and the mechanism of action, finasteride may cause abnormal development of external genitalia in a male fetus if administered to a pregnant female. Females who are pregnant or may potentially be pregnant should not handle crushed or broken finasteride tablets. Finasteride tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets have not been broken or crushed. If a pregnant female comes in contact with crushed or broken finasteride tablets, the contact area should be washed immediately with soap and water. [See Contraindications (4), Use in Specific Populations (8.1), Clinical Pharmacology (12.3 and 12.1), and How Supplied/Storage and Handling (16)].
Finasteride tablets are not indicated for use in pediatric patients [see Use in Specific Populations (8.4)and Clinical Pharmacology (12.3)] or females [see also Warnings and Precautions (5.3), Use in Specific Populations (8.1), Clinical Pharmacology (12.3), and How Supplied/Storage and Handling (16)] .
Treatment with finasteride for 24 weeks to evaluate semen parameters in healthy male volunteers revealed no clinically meaningful effects on sperm concentration, mobility, morphology, or pH. A 0.6 mL (22.1%) median decrease in ejaculate volume with a concomitant reduction in total sperm per ejaculate was observed. These parameters remained within the normal range and were reversible upon discontinuation of therapy with an average time to return to baseline of 84 weeks.
