Bioequivalence Study of Flurbiprofen 8.75 mg Lozenge vs. the Reference Product Strepfen 8.75 mg Lozenge in Healthy Volunteers

The present study has been designed to compare flurbiprofen pharmacokinetic profile after administration of flurbiprofen 8.75 mg lozenges, marketed by ACRAF, S.p.A., Italy (test product), and the marketed Strepfen 8.75 mg honey and lemon lozenges reference product. (Reckitt Benckiser Portugal SA).

• Contraception and fertility (women only): females of child-bearing potential must be using at least one of the following reliable methods of contraception:
• Hormonal oral, implantable, transdermal, or injectable contraceptives for at least 2 months before the screening visit
• A non-hormonal intrauterine device [IUD] or female condom with spermicide or contraceptive sponge with spermicide or diaphragm with spermicide or cervical cap with spermicide for at least 2 months before the screening visit
• A male sexual partner who agrees to use a male condom with spermicide
• A sterile sexual partner Women of non-child-bearing potential or in post-menopausal status for at least 1 year will be admitted.

For all women, pregnancy test result must be negative at screening and day -1.

Exclusion Criteria:

• Electrocardiogram (12-lead ECG in supine position): clinically significant abnormalities.
• Physical findings: clinically significant abnormal physical findings which could interfere with the objectives of the study; subjects with dry mouth conditions or with any other diseases/problems of the mouth which the investigator considers may affect the outcome of the study.
• Laboratory analyses: clinically significant abnormal laboratory values indicative of physical illness.
• Allergy: ascertained or presumptive hypersensitivity to the active principle and/or formulations' ingredients; history of anaphylaxis to drugs or allergic reactions in general, which the investigator considers may affect the outcome of the study.
• Diseases: significant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory, skin, haematological, endocrine or neurological diseases that may interfere with the aim of the study.
• Medications: medications, including over the counter (OTC) medications and herbal remedies, in particular flurbiprofen, for 2 weeks before the start of the study. Hormonal contraceptives for females will be allowed
• Investigative drug studies: participation in the evaluation of any investigational product for 3 months before this study. The 3-month interval is calculated as the time between the first calendar day of the month that follows the last visit of the previous study and the first day of the present study
• Blood donation: blood donations for 3 months before this study

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Flurbiprofen 8.75 mg; Flurbiprofen 8.75 mg lemon and honey flavour lozenge	Drug: Flurbiprofen Test 8.75 MG; Subjects will be asked to swallow saliva before dosing. For each administration, subjects will move the lozenge around in their mouth, suck on the lozenge continually for 15 min and swallow saliva at any time during the product administration procedures, being very careful not to swallow the lozenge.
Active Comparator: Strepfen 8.75 mg; Strepfen 8.75 mg lemon and honey lozenge	Drug: Flurbiprofen Reference 8.75 MG; Subjects will be asked to swallow saliva before dosing. For each administration, subjects will move the lozenge around in their mouth, suck on the lozenge continually for 15 min and swallow saliva at any time during the product administration procedures, being very careful not to swallow the lozenge.; Other Names: Strepfen
