Brief Summary:
Objective to study the pharmacokinetic, safety and efficacy of Single-dose and multiple-dose of benzonatate in Chinese healthy male and female subjects.

Condition or disease Intervention/treatment Phase
Cough Drug: Group A: Benzonatate 100mg Drug: Group B: Benzonatate 200mg Drug: Group C: Benzonatate 400mg Phase 1

Detailed Description:
Objective to study the pharmacokinetic, safety and efficacy of Single-dose and multiple-dose of benzonatate in Chinese healthy male and female subjects. The study was designed to be single-center, open, and parallel, there are 3 groups A, B, C, each group will be enrolled in 12 healthy adult subjects. Single-dose of pharmacokinetics will be carried out in group A and C, single-dose and multiple-dose of pharmacokinetics will be carried out in group B. Subjects in group A and C will be given benzonatate of 100mg and 400mg respectively, Subjects in group B will be given benzonatate of 200mg. Subjects in group A and C will be given benzonatate once after a 10-hour fast in the first day of the trail. Subjects in group B will be given benzonatate once after a 10-hour fast in the first day of the trail, and they will be given benzonatate thrice in the second and third day of the trail, in the fourth day, they will be given benzonatate once after a 10-hour fast. After completing blood collection and safety inspection at the appropriate time points, subjects can leave the test center. The main pharmacokinetic parameters will be calculated, to fully reflect the characteristics of drug absorption, distribution, metabolism and excretion in human body. The main pharmacokinetic parameters include Tmax, Cmax, Css, AUC0-t, AUC0-∞, λz, t1/2, Vd/F, CL/F, and so on.

Primary Outcome Measures :
  1. Tmax [ Time Frame: day 1 and day 4 ]
    Time to peak

  2. Cmax [ Time Frame: day 1 and day 4 ]
    peak plasma concentration

  3. t1/2 [ Time Frame: day 1 and day 4 ]
    elimination half-life time

  4. AUC0-t [ Time Frame: day 1 and day 4 ]
    Area under the plasma concentration versus time curve from the medication to the last time the concentration can be measured

  5. AUC0-∞ [ Time Frame: day 1 and day 4 ]
    Area under the plasma concentration versus time curve from the medication extrapolate the infinity time

  6. CL/F [ Time Frame: day 1 and day 4 ]
    elimination ratio
