Tradipitant Approved As First New Treatment For Motion Sickness In 40 Years

The <span>US Food and Drug Administration</span> (<span>FDA</span>) has approved <span>tradipitant</span> to be sold under the brand name <span>Nereus</span>, for the prevention of vomiting induced by motion in adults — a first in the last four decades. 

<span>Motion sickness</span> affects an estimated 65 to 78 million Americans—roughly 25 to 30 percent of adults—during everyday travel by car, plane, or boat. For decades, patients have had no meaningful new treatment options. 

Tradipitant is an oral neurokinin-1 (NK-1) receptor antagonist that prevents motion-induced vomiting in adults. 

It is an oral capsule, often taken 60 minutes before travel to block signals causing nausea.

The drug by <span>Vanda Pharmaceuticals</span> is now commercially available across the US. 

"Today marks an important milestone for the tens of millions of Americans who experience motion sickness symptoms during common travel," said Mihael H. Polymeropoulos, M.D, President, CEO, and Chairman of Vanda, in a statement. 

<h2>How Tradipitant Prevents Motion Sickness?</h2>

Motion sickness occurs when the brain receives conflicting signals from the eyes, inner ear, and body while in motion. This sensory mismatch is believed to trigger the release of substance P, which activates NK-1 receptors in the central nervous system and ultimately leads to nausea and vomiting. 

Tradipitant works by blocking these receptors, interrupting the vomiting pathway. 

"NEREUS is a selective, high-affinity antagonist of human substance P/neurokinin-1 (NK-1) receptors that can block the vomiting center of the brain,” Polymeropoulos said. 

Tradipitant was approved by the FDA, following two pivotal Phase 3 clinical trials—Motion Syros and Motion Serifos—conducted under real-world conditions on the open sea.

Both studies demonstrated that tradipitant significantly prevents vomiting compared to placebo, confirming the drug's effectiveness in actual sea travel conditions. It is the first new prescription option for people with a history of motion sickness in over 40 years. 

It employs a novel mechanism as a selective, high-affinity antagonist of human substance P/NK-1 receptors. It offers simple dosing with just one or two capsules a day taken approximately an hour before travel. 

<h2>Is Tradipitant Safe? Are There Any Side-Effects?</h2>

According to Vanda Pharmaceuticals, tradipitant may impair abilities required for driving a motor vehicle or operating heavy machinery. 

Combining tradipitant with sedatives or medications that increase the drug's levels may increase this effect. If use together cannot be avoided, your doctor may warn against driving or operating heavy machinery.

The most common side effects associated with tradipitant include drowsiness, headache, and fatigue. 

Moreover, strong CYP3A4 inhibitors may increase NEREUS™ levels and the risk of side effects, the company said.

There are limited data on tradipitant's use in pregnant women and children. 

Tradipitant is also not recommended in patients with liver problems or severe kidney problems.
