Dutasteride is the latest drug developed to combat baldness, and it is used by some patients. The drug was developed by Glaxo.
This medicine has the same action as Finasteride but it is more potent.
It is used and recommended in the treatment of prostatic hyperplasia.
Nonetheless this drug did not obtain FDA (Food and Drug Administration) approval as a drug indicated for hair loss treatment.

Its immediate side effects are important and long-term side effects are yet unknown.
The Glaxo Company itself has recommended that this drug should not be used as a drug for the treatment of hair loss.

I myself do not commend this medicine.
