At a glance
Finasteride + Tadalafil is a combination used for the treatment of signs and symptoms of Benign Prostatic Hyperplasia in men with an enlarged prostate for up to 26 weeks.
Description
Finasteride + Tadalafil capsule is indicated to initiate treatment of the signs and symptoms of Benign Prostatic Hyperplasia (BPH) in men with an enlarged prostate for up to 26 weeks.
Finasteride is a specific inhibitor of steroid Type II 5α-reductase which converts testosterone into 5α-dihydrotestosterone (DHT). Finasteride lowers DHT hormone levels, which is a cause of prostate growth. Tadalafil is a selective inhibitor of PDE5 which relaxes the smooth muscles of the prostate, resulting in the release of the restriction to the flow of urine through the urethra.
Indications
- Benign Prostatic Hyperplasia (BPH): Used to initiate treatment of signs and symptoms of BPH in men with an enlarged prostate for up to 26 weeks.
Therapeutic class
BPH/ Urinary retention/ Urinary incontinence
Pharmacological class
5-alpha Reductase Inhibitor + PDE5 Inhibitor
Pharmacology
This is the combination of Finasteride, a specific inhibitor of steroid Type II 5a-reductase and Tadalafil, a selective inhibitor of phosphodiesterase type-5 (PDE5). Finasteride lowers DHT hormone levels, which is a cause of prostate growth. Tadalafil inhibits PDE5 to relax smooth muscles of the prostate, resulting in release of restriction to urine flow through the urethra.
Mechanism of action
Finasteride reduces prostate size by lowering DHT; Tadalafil improves urine flow by relaxing prostate smooth muscles through PDE5 inhibition.
