Inclusion Criteria

Healthy subjects, males and females aged 18 to 50 years of age. Females must be sterile or using adequate contraception. Participants must not have taken any prescription medications for at least 14 days or over-the-counter medications for at least 7 days before the start of each study phase, with the exception of oral contraceptives and the study medication.
All subjects must be deemed healthy on the basis of a medical history, physical exam (including vital signs and ECG recording), urinalysis, and blood biochemical and haematological examinations.

Exclusion Criteria

1.Women who are pregnant or nursing.
2. Women of childbearing potential who are unwilling to take adequate contraceptive precautions, i.e., a hormonal contraceptive, an intrauterine device, double-barrier method, or abstinence. A woman of childbearing potential is defined as any female who is less than 2 years post-menopausal or has not undergone a partial or total hysterectomy or surgical sterilisation, e.g. bilateral tubal ligation, bilateral oophorectomy.
3. Women of childbearing potential who are unwilling to undergo a urine pregnancy test.
4. Have an alcohol intake in excess of 14 units per week for females and 21 units per week for males.
5. Have a history of drug abuse or positive test results for drug abuse during screening.
6. Unwilling to abstain from smoking throughout the whole duration of the study
7. Unable and refuse to abstain the used prescription drugs (not including oral contraceptives) within 14 days prior to study drug administration or have used over-the-counter drugs or herbal products within 7 days prior to study drug administration.

• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
To determine the pharmacokinetic parameters (Cmax, AUCt, AUCinf, Tmax) of pirfenidone and compare them between all four treatment groups[Plasma time concentrations will be determined from the blood samples collected at 10, 20, 30, 45 minutes and 1.00, 1.25, 1.50, 2.00, 2.50, 3.00, 4.00, 6.00, 8.00, 10.00 and 12.00 hours after study drug administration. ]

Secondary Outcome Measures

Name	Time	Method
To monitor and compare the safety and tolerability of pirfenidone amongst the different treatment groups. This is a composite secondary outcome.<br>The safety evaluation will consist of recording spontaneously reported adverse events and by measurements of vital signs (blood pressure, heart rate, respiratory rate, and temperature).[Safety will be evaluated during each study period at Days 0, 7, 14 and 21 following study drug administration. ]
