Brief summary
The Safety, Tolerability and Pharmacokinetic Study of Asthma Treatment Drug Litapiprant Tablets in Healthy Male and Female subjects.
Detailed description
This was a Randomized,Double-blind, Placebo-controlled, Single Ascending Dose, Single-center Study to Assess the Safety, Tolerability and Pharmacokinetic of Litapiprant Tablets in Healthy Male and Female subjects. A total of 60 healthy subjects were divided into 7 groups. Group 1 consist of 4 subjects, 3 subjects will receive Litapiprant Tablets and 1 subject will receive placebo.Group 2,3,5,6 consist of 8 subjects respectively, in each group, 6 subjects will receive Litapiprant Tablets and 2 subjects will receive placebo.Group 4,7 consist of 12 subjects respectively, in each group, 10 subjects will receive Litapiprant Tablets and 2 subjects will receive placebo.
