Description

Inclusion Criteria:

1. The subject is Caucasian & aged between eighteen to fifty years (18 - 50), both inclusive.
2. The subject is within the limits for his height & weight as defined by the body mass index range (18.5 - 30.0 Kg/m2).
3. The subject is willing to undergo the necessary pre- & post- medical examinations set by this study.
4. The results of medical history, physical examination, vital signs & conducted medical laboratory tests are normal as determined by the clinical investigator.
5. The subject tested negative for Hepatitis B (HBsAg), Hepatitis C (HCVAb), human immunodeficiency virus (HIV Ab).
6. There is no evidence of psychiatric disorder, antagonistic personality, and poor motivation, emotional or intellectual problems likely to limit the validity of consent to participate in the study or limit the ability to comply with protocol requirements.
7. The subject is able to understand and willing to sign the informed consent form.
8. For female subjects: a negative pregnancy test must be confirmed, and if sexually active, at least 4 weeks of highly effective contraceptive method must be used prior to IMP administration and throughout the study progress until last visit; highly effective methods comprise hormonal contraceptives, intrauterine devices IUDs, sexual abstinence or vasectomized partner (success of vasectomy was medically proven). For subjects using a hormonal contraceptive method, a barrier form of contraception should be combined with the hormonal contraception.
9. The subject kidney and liver (AST & ALT enzymes) functions tests are within normal range.
10. The subject has normal gastrointestinal, respiratory & cardiovascular systems.

Exclusion Criteria:

2. The subject has suffered an acute illness one week before dosing.
3. The subject has a history of or concurrent abuse of alcohol.
4. The subject has a history of or concurrent abuse of illicit drugs.
5. The subject has a history of hypersensitivity and/or contraindications to the study drug and any related compounds.
6. The subject has been hospitalized within three months before the study or during the study.
7. The subject is on special diet (for example subject is vegetarian).
8. The subject has consumed caffeine or xanthine containing beverages or foodstuffs within two days before dosing and until 24 hours after dosing in all study periods.
9. The subject has taken a prescription medication within two weeks or even an over-the-counter product (OTC) within one week before dosing in each study period and any time during the study, unless otherwise judged acceptable by the clinical investigator.
10. The subject has taken grapefruit containing beverages or foodstuffs within seven (7) days before first dosing and any time during the study.
11. The subject has been participating in any clinical study (e.g., pharmacokinetics, bioavailability and bioequivalence studies) within the last 80 days prior to the present study.
12. The subject has donated blood within 80 days before first dosing.
13. The subject has a history or presence of cardiovascular, pulmonary, renal, hepatic, gastrointestinal, hematological, endocrinal, immunological, dermatological, neurological, musculoskeletal or psychiatric diseases.
14. The subject has consumed drugs that may affect pharmacological or pharmacokinetic properties of Ibuprofen (for example: aspirin, celecoxib, ciprofloxacin, diclofenac, etodolac, fish oil, heparin, ketorolac, ketoprofen, naproxen, rivaroxaban, vitamin B12, vitamin C and vitamin D3) two weeks before dosing, during the study and two weeks after dosing.
15. Pregnant; with positive serum pregnancy test or breast-feeding female subjects.
16. The subject has a history of, or active, peptic ulceration, gastritis, esophagitis, gastrointestinal bleeding or perforation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
