Brief Summary:
The main objective is to evaluate the effect of single dose Propionyl-L-Carnitine Hydrochloride on clinical pharmacokinetic characteristics and its effect of clinical pharmacokinetic characteristics and safety on healthy Chinese subjects to provide a basis for market authorization registration.

Condition or disease Intervention/treatment Phase
Peripheral Arterial Disease Drug: Propionyl L-carnitine Hydrochloride Phase 1

Detailed Description:

Before the official start of the study, to determine the appropriate dosing interval and a preliminary assessment of drug safety, first carried out the pre-trial, 4 subjects with different gender in half, after 7 days of run-in period, collect baseline background sampling point at day 4, no medication but water intake. At day 8 fasting oral propionyl L-carnitine hydrochloride tablets 0.5g, according to pre-designed schedule for blood samples, urine samples and clinical indicators, provide a reference for official trial.

Official trial is a single, open label, self-controlled, three-period, dose escalation, period fasting single oral administration trial. 12 chinese healthy adult subject met the inclusion criteria 12 people, each gender in half. Each subject first pass 7 days of run-in period, to eliminate the residual substances in food L-carnitine, stable baseline level of endogenous L-carnitine class substance within the subject; at day 4 was baseline sampling point, tno medication but water intake; at day 8 (1st period day 1) fasting oral propionyl L-carnitine hydrochloride tablets 1g; at day 12 (2nd period of day 1) fasting oral hydrochloride propionyl L-carnitine tablets 2g; the first 16 days (3rd period day 1) fasting oral propionyl L-carnitine hydrochloride tablets 4g.Throughout the trial period, control the subjects' diet, eating only allowed as far as possible food without substance L-carnitine class and drink boiled water,diet at sampling day 4, 8, 12, 16 need to be fixed consistently. Every 4 days of dosing interval washout period.

Subject need to follow blood, urine collection and diet control as required by protocol before the day of run-in period. During the trial should avoid vigorous exercise, meanwhile to avoid long-time bedding.
