tradipitant 85 MG Oral Capsule

INDICATIONS AND USAGE NEREUS is indicated for the prevention of vomiting induced by motion in adults. NEREUS is a substance P/neurokinin 1 (NK1) receptor antagonist indicated for the prevention of vomiting induced by motion in adults. ( 1 )

DOSAGE AND ADMINISTRATION The recommended dosage of NEREUS is 85 mg or 170 mg as a single oral dose approximately 60 minutes before an event expected to cause vomiting induced by motion. The safety of NEREUS for the prevention of vomiting induced by motion in adults for more than 90 doses has not been established in clinical trials. ( 2.1 ) The maximum dosage in a 24-hour period is a single dose of 85 mg or 170 mg. ( 2.1 ) Administer on an empty stomach, at least 1 hour prior to or 2 hours after a full meal. ( 2.1 ) 2.1 Recommended Dosage and Administration The recommended dosage of NEREUS is 85 mg or 170 mg as a single oral dose. Use the lowest effective dose. The safety of NEREUS for the prevention of vomiting induced by motion in adults for more than 90 doses has not been established in clinical trials [see Adverse Reactions (6.1) ] . Administer NEREUS orally approximately 60 minutes before an event expected to cause vomiting induced by motion. The maximum dosage in a 24-hour period is a single dose of 85 mg or 170 mg. Administer NEREUS on an empty stomach, at least 1 hour prior to or 2 hours after a full meal [see Clinical Pharmacology (12.3) ] .

WARNINGS AND PRECAUTIONS Effects on the Ability to Drive or Operate Machinery: May impair mental and/or physical abilities required for driving a motor vehicle or operating heavy machinery. Concomitant use of other drugs that cause central nervous system depression and strong CYP3A4 inhibitors may increase this effect. If concomitant use is unavoidable, warn patients against driving and other activities requiring complete mental alertness. ( 5.1 , 7.1 ) 5.1 Effects on the Ability to Drive or Operate Machinery In placebo-controlled clinical trials, somnolence (6%, 12%) and fatigue (6%, 8%) were adverse reactions reported in subjects who took a single dose of 85 mg or 170 mg NEREUS, respectively [see Adverse Reactions (6.1) ] . NEREUS may impair the mental and/or physical abilities required for driving a motor vehicle or operating heavy machinery. Concomitant use of other drugs that cause central nervous system depression and strong CYP3A4 inhibitors may increase this effect [see Drug Interactions (7.1) ] . If concomitant use is unavoidable, warn patients against driving and other activities requiring complete mental alertness.

CONTRAINDICATIONS None. None. ( 4 )

Mechanism of Action Tradipitant is a selective, high-affinity antagonist of human substance P/neurokinin 1 (NK1) receptors. Tradipitant does not have affinity for NK2 and NK3 receptors, serotonin (5-HT3), dopamine (D2), cholinergic, or histamine (H1) receptors. Tradipitant has been shown in animal models to inhibit drug induced emesis. Human Positron Emission Tomography (PET) studies with tradipitant have shown that tradipitant crosses the blood brain barrier and occupies brain NK-1 receptors. The exact mechanism by which tradipitant exerts its therapeutic effect is not fully established.
