Which medication is a 5-alpha reductase inhibitor? new 2022
Question table
5-alpha-reductase inhibitors are a group of drugs that are used in the treatment of an enlarged prostate gland (benign prostatic hyperplasia) and male pattern hair loss. Drugs in this class are finasteride (marketed as Proscar [finasteride 5 mg] and Propecia [finasteride 1 mg]) and dutasteride (marketed as Avodart).
Is Cialis a 5-alpha reductase inhibitor?
These medications target the 5-α-reductase (5-AR) enzyme, responsible for catalyzing the conversion of testosterone to dihydrotestosterone (DHT) [Roehrborn, 2005]. A more recently approved third class of medication are PDE-5 inhibitors such as tadalafil (Cialis, Eli Lilly, Toronto, Ontario, Canada).
Does high DHT cause erectile dysfunction?
These results show that DHT is the active androgen in the prevention of erectile failure seen in castrated rats, and suggest that this effect may be mediated, at least partially, by changes in nitric oxide synthase levels in the penis.
What happens when you block 5-alpha reductase?
This enzyme converts some of the testosterone you produce into dihydrotestosterone (DHT). DHT plays a role in prostate growth, acne, growth of facial hair, and male pattern baldness. The 5ARIs work by suppressing the 5-alpha reductase enzyme. This decreases the amount of DHT your body produces.
How can I lower my 5-alpha-reductase naturally?
Onions (and other foods rich in quercetin) In preclinical studies, quercetin has been shown to inhibit the production of DHT from testosterone by blocking the action of the enzyme alpha-5 reductase and decreasing oxidative stress ( 16 ).
