While using cocaine recreationally remains illegal, the drug does have some use in the medical profession. As it turns out, the Food and Drug Administration (FDA) has approved a nasal spray that contains cocaine as one of its ingredients.

Lannett Company (NYSE:LCI), a small-cap drug manufacturer, received FDA approval for Numbrino, the first branded drug in the company's 78-year history. The nasal spray will be marketed to doctors as a local anesthetic for minor surgeries around the nasal cavities of patients, but will not be available in retail pharmacies.

Although cocaine is a Schedule II drug, medical professionals use cocaine for its effectiveness in numbing highly sensitive tissues and constricting blood vessels to prevent bleeding. Ear, nose, and throat surgeons, in particular, find cocaine (also known as cocaine hydrochloride) especially useful when performing operations.

A big win for a small company

This isn't the first time that the FDA has approved a local anesthetic with cocaine as an ingredient. Back in 2017, another cocaine hydrochloride product called Goprelto was approved by the FDA. It's similar to Numbrino in that it's an anesthetic for nasal cavity surgeries.

Although cocaine-based anesthetics tend not to be addictive when employed for a single use by a medical professional, they still need to undergo significant clinical testing before they are approved. Numbrino has also had two phase 3 trials supporting its effectiveness, alongside a separate phase 1 trial.

Shares of Lannett have shot up in response to the news, but the company has still lost around 85% of its market value over the past five years. Time will tell whether Numbrino's approval could be the start of a comeback for the company.
