Finasteride (Propecia) is an oral medication that is prescribed for the treatment of male pattern baldness (androgenic alopecia) in men. The mechanism of action of finasteride is unknown, but it has been hypothesized that finasteride competitively inhibits the conversion of testosterone to dihydrotestosterone (DHT), a hormone implicated in hair loss and scalp inflammation [
,
]. DHT is a potent derivative of testosterone, and has been implicated in the development of benign prostatic hyperplasia (BPH) and male pattern baldness (MPB), as well as the progression of MPB [
DHT can also play a role in hair loss by inhibiting the synthesis of testosterone from dihydrotestosterone (DHT). In the human body, DHT is converted into DHT by 5-alpha reductase, an enzyme that is primarily involved in the synthesis of androgen hormones [
Finasteride, a 5-alpha reductase inhibitor, blocks the action of 5-alpha reductase, thus inhibiting the conversion of testosterone to dihydrotestosterone (DHT), thereby reducing the concentration of dihydrotestosterone (DHT). Finasteride is effective in reducing hair loss and MPB symptoms associated with these conditions [
], while the pharmacological action of finasteride is not well understood. In this study, we investigated the effects of finasteride on hair loss and MPB among men with androgenetic alopecia.
All participants gave written informed consent prior to their participation in this study. A protocol was approved by the Institutional Review Board of the University of Southern California. The Institutional Review Board of the University of California, San Diego, approved the study protocol. A retrospective chart review was conducted to identify and retrospectively evaluate the study participants. The participants were recruited through advertisements in the local newspaper advertisements. The advertisements indicated the study was being conducted in compliance with all relevant guidelines and regulations, including the Declaration of Helsinki, and no additional restrictions were placed on the study participants. The advertisements included articles describing the study’s purpose, procedures, results, and potential risks associated with finasteride use. The study was also conducted in compliance with local regulations regarding the use of medication and the privacy and confidentiality of the participants. The advertisements were not sponsored by any pharmaceutical company or was provided without authorization from the study sponsor. The advertisements were reviewed and approved by the Institutional Review Board of the University of Southern California, and written informed consent was obtained from the participants. Participants underwent a hair loss screening and were screened for eligibility by a dermatologist (M. C.) at each stage of their hair loss cycle. All participants were screened for eligibility at the start of the study, and medical records were reviewed for eligibility at the end of the study. A screening visit was conducted at the end of the study and participants were excluded if they had: a medical problem with the hair loss, any previous hair loss, or any type of medical or dermatological condition that might have affected the hair loss.
A dermatologist (M. C.) was a member of a clinical team involved in the screening process of participants. C.) evaluated the participant’s eligibility for the study. C.) provided the participant with a medical history and a physical examination. C.) assessed the participant’s medical history and performed a physical examination. A medical history was taken by participants before screening and for any relevant information. A physical examination was conducted by a medical investigator (M. C.). The screening examination was conducted by a medical investigator (M. A medical history was also obtained by participants at the start of the study and included a physical examination, a medical exam, and a medical history review. A physical exam included an examination of the scalp and an examination of the participants’ scalp. A medical exam was also performed to determine the extent of the hair loss.

The UK patent forPropecia, a hair loss treatment for men, expired on the 11th Oct 2014. A few days later ‘generic Propecia’ or more accurately ‘generic finasteride’ became available from UK pharmacies. A generic medicine is a medicine which is the same as a branded original, but is prescribed and supplied by its medical name, rather than its brand name.
Propecia is a brand name. The active ingredient of Propecia tablets isfinasteride 1mg. Propecia tablets and finasteride 1mg tablets are medically the same.
Dr Fox supplies both from the drug companyMerck(MSD), which held the original patent, and lower cost, which other drug companies have made available since Merck’s UK patent expired.
When a medicine comes off patent price can fall dramatically. Men, who previously paid very high prices for Propecia, may be able to buy medically identical finasteride 1mg at lower prices.
When a medicine is under patent it can only be sold legally by the patent holder. This means the patent holder, which is normally the drug company which paid to develop the medicine in the first place, is free to market the medicine without competition from other pharmaceutical companies. The result is usually very high prices. When a patent expires other drug companies usually start to produce the same medicine, known as a generic copy, and start to compete on price. As a result the cost to patients tends to fall.
The cost to patients of a medicine depends on various factors; how much it costs to produce, how much demand there is, how many drug companies supply the same medicine, and how flexible the market is. Even when the wholesale supply price of a medicine falls, the price patients pay does not always fall by the same amount. Retail pharmacies may try not to pass on reduced supply costs to patients, and instead use falling wholesale prices to boost profits. If there is price competition between retailers, as there tends to be between online pharmacies and online clinics, price to patients usually fall in line with falls in wholesale supply costs, but not always.
Dr Fox is one of the lowest cost suppliers of most medicines for both branded and generic medicines.
At the moment (10 Dec 2014) only three pharmaceutical companies, apart from Merck, are supplying finasteride 1mg tablets. These companies areTrent,Actavis, andMylanAt the time of writing, all are offering their generic equivalent of Propecia at the same price; about 10% less than branded Propecia. Prices will hopefully tumble further in the days and weeks to come (as happened when last year).UPDATE JANUARY 2022Generic finasteride is now less than 30% of the price of Propecia from Dr Fox.
The original patent holder, Merck (MSD) may reduce the price of Propecia, or start to market its own generic finasteride 1mg alongside branded Propecia.
Not all men who previously took Propecia will switch to generic finasteride 1mg, even if the price of Propecia remains high and generic finasteride is a lot cheaper. If a patient is happy with a particular brand of tablet, they often will not switch to a lower cost equivalent, even if they are reliably advised that one tablet is medically the same as the other. Whether or not they switch depends on how much they wish to economise, and all the other factors which keep people buying certain products at high prices when they do not have to.
Finasteride 1mg tablets are taken daily to reduce hair loss in men, and can promote hair regrowth. See Dr Fox for details.
