Spironolactone vs Eflornithine

Buy 99% Cheap Spironolactone Powder

As we all know, both spironolactone and eflornithine hydrochloride can be used for female facial hirsutism, but what are their differences?

#1. Dosage forms

Spironolactone is made into tablets or oral suspensions but never used topically. While eflornithine is mainly made into topical creams well-known as Vaniqa of Gillette. There was an eflornithine injection, but it was discontinued for safety reasons.

#2. Working Mechanism

Spironolactone is also used for facial hirsutism due to its androgen-blocking ability. It works by blocking androgen’s ability to affect the human body. It is similar to finasteride on androgen blocking-mechanism. But it may take 3 to 6 months for spironolactone to work. Many will use birth control pills together with spironolactone for a better facial-hair-ridding effect because birth control pills can reduce androgen production.

Eflornithine hydrochloride is also used to treat hirsutism, but it works by interfering with a chemical in hair follicles under the skin to slow hair growth when applied topically. Please note, eflornithine topical does not permanently remove facial hair or prevent hair growth.

#3. Social influence

The topical eflornithine cream has long been indicated for the treatment of facial hirsutism in women. Eflornithine cream is the main-stream cure for hirsutism, while spironolactone is only auxiliary.

In clinical studies with Vaniqa, 81% percent of women showed clinical improvement after twelve months of treatment. Positive results were seen after eight weeks. However, discontinuation of the cream caused regrowth of hair back to baseline levels within 8 weeks. But eflornithine topical cream does significantly reduce the psychological burden of facial hair.

#4. Price

 Due to the small demand for eflornithine hydrochloride in the market, eflornithine did not get commercially produced in China and its price has been very high. While spironolactone has been commercially produced long ago, the cost of spironolactone is only 1/10 of eflornithine.
