| Experimental: Ammoxetine Hydrochloride Enteric-coated Tablets<br>There will be 7 ascending cohorts . Each cohort will be administered in different dose once for 7 days. | Drug: Ammoxetine Hydrochloride Enteric-coated Tablets<br>* There will be 7 ascending cohorts. The first cohort will be administered 2.5 mg once. The second cohort will be administered 7.5 mg. The third cohort will be administered 15 mg once. The forth cohort will be administered 30 mg once. The fifth cohort will be administered 45 mg once. The sixth cohort will be administered 65 mg once.The seventh cohort will be administered 100 mg once. The results of each dose group were shown to be safe and tolerable, and then the next dose group was tested.<br>|
