Latisse Improves Eyelash Growth in Controlled Study

Latisse Improves Eyelash Growth in Controlled Study

Latisse, which is the brand name for the drug bimatoprost, has been found to effectively and safely grow eyelashes in a double-blinded scientific study published in the May 2012 issue of the Journal of the American Academy of Dermatology.

The study found that the drug starts showing improved eyelash growth at week 4 of using the medication. The growth is notable by week 8 and even more substantial by week 12. The majority of subjects using bimatoprost, 78.1% of the group, found improvements in eyelash prominence, length, fullness, and darkness by week 16. Only 18.4% of subjects using the placebo found such improvements at 16 weeks.

In the safety component of the study, adverse events were tallied and subjects were given ophthalmic examinations. Bimatoprost was found to have a “very good” safety profile. The only adverse event that occurred in a statistically significant greater proportion among those who used bimatoprost was conjunctival hyperemia, also known as “red eye”. This adverse event happened in only 3.6% of subjects — five out of 137 — and none of the subjects discontinued participation in the study. Ophthalmic examination of subjects during the study revealed that there is no statistically significant change in iris pigmentation due to bimatoprost. There was also no statistically significant change in visual acuity.

Bimatoprost, which mimics a type of “messenger molecule” called a prostaglandin, was initially designed to treat glaucoma. It was known for several years that the drug’s side effect was eyelash growth, and it was approved by the Food & Drug Administration in 2008 under the brand name of Latisse. The physiological mechanism by which bimatoprost affects eyelash growth is unknown and requires further scientific study.

Latisse — which is owned by the California-based pharmaceutical company Allergan, Inc. — is also being studied as a treatment for hair loss. That study is underway, and is on-going as of the most recent update in January 2012. The study should be complete by September 2012.

What Is The Status Of The Latisse For Hair Loss Study?

Q: I saw your post on the clinical trials of Latisse (bimatoprost) for hair loss on the scalp. What is the status of the study? — B.V., New Providence, NJ

A: Allergan, the company that makes Latisse, conducted safety and efficacy testing of three formulations of the drug for men with androgenetic alopecia (male pattern baldness). Latisse is a drug that is approved by the FDA to help eyelash growth at a concentration of 0.03 %. The drug is applied daily to the upper eyelid.

Allergan studied the results of three formulations of Latisse (Bimatoprost .03% Opthalmic Solution) comparing them to results of a control option and also an over-the-counter minoxidil 5% solution. The drugs were applied directly to the scalp, and the progression of hair loss was measured.

This study began in June 2011 and the results were published in April 2014. The results of the study did not indicate that Latisse would be a viable alternative to use on the scalp to prevent hair loss.

It should also be noted that the cost of bimatoprost, the active ingredient in Latisse is significantly more expensive than minoxidil, the active ingredient in Rogaine. This means that even if the two treatments were equally effective, it would be cost-prohibitive to treat baldness with Latisse.

Latisee (Bimatoprost .03% Opthalmic Solution) has not been FDA approved for the treatment of scalp hair loss.

Latisse Drug as Hair Loss Treatment? Trials Under Way on New Formulation of Bimatoprost

Latisse, the brand name for the drug bimatoprost, is commonly used to promote eyelash growth in women who want their eyelashes to be longer, thicker, and darker, typically for cosmetic reasons. It is also used to promote growth of eyebrow hair.

In a publication on ClinicalTrials.gov titled, “Safety and Pharmacokinetics Study of New Formulation of Bimatoprost in Patients With Alopecia,” Allergan, the pharmaceutical company that produces Latisse, has announced a new study on the safety and efficacy of a new formulation of bimatoprost for use as a topical hair loss treatment for general baldness.

The study, based out of Tempe, Arizona, will test two different formulations of bimatoprost in men who suffer from moderate male pattern baldness and women who have moderate female patterned alopecia.

According to the details of the study, the test involves, “One mL dose applied evenly onto pre-specified balding area on scalp – single dose in the am followed by multiple doses daily in the am for 14 days.” The goal of the testing is to measure the results of a single dose of bimatoprost, as well as multiple doses over time. The completion date of the study is February 2011, so we will look for the results and share them with you when they are available.

Update:

The results of the study have been published and it did not result in the FDA approving Latisse for hair loss on the scalp. Latisse was found to be not nearly as effective in treating hair loss as the control group that used minoxidil 5% solution. See the results of the study on ClinicalTrials.gov.
