Description

Single centre, subject and observer blinded, placebo controlled, cross-over study of the effect of oral ibuprofen and topical hydrocortisone-21-acetate on ultraviolet radiation (UVR) induced pain and inflammation in healthy volunteers conducted in two segments and using an intra-individual comparison of application areas.

Subjects that signed the informed consent and are eligible to the study will be irradiated on the back to evaluate their individual minimal erythema doses (MEDs). Read out to determine MED will be done within 24 h after UVR.

A training session (without study medication) using the MED definition areas will be performed in order to introduce subjects to the testing and rating procedures.

Subjects will come in within 14 days of screening to start the first Segment of the study. Eligible subjects will be randomised to receive either:

1. IB 600 mg, applied orally b.i.d., or

2. OP, applied orally b.i.d.

Allocation of topical treatment to these areas will be randomly assigned to:

1. PG, 15 μl/cm2 applied topically b.i.d., or

2. HC, 15 μl/cm2 applied topically b.i.d.

Defined areas will be irradiated with defined dosages of UVR. Assessment of hyperalgesia to heat and signs of inflammation (erythema, skin temperature) for all areas will be performed.

Subjects return within 4 to 11 days to the study site for the second segment of the study. Treatment allocation will be crossed-over and new treatment areas will be selected on the back.

Medical and Biotech [MESH] Definitions

Excess production of ADRENAL CORTEX HORMONES such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE. Hyperadrenal syndromes include CUSHING SYNDROME; HYPERALDOSTERONISM; and VIRILISM.

A metabolite of PROGESTERONE with a hydroxyl group at the 17-alpha position. It serves as an intermediate in the biosynthesis of HYDROCORTISONE and GONADAL STEROID HORMONES.

The wide middle zone of the adrenal cortex. This zone produces a series of enzymes that convert PREGNENOLONE to cortisol (HYDROCORTISONE) via 17-ALPHA-HYDROXYPROGESTERONE.

The main glucocorticoid secreted by the ADRENAL CORTEX. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions.

A naturally occurring glucocorticoid. It has been used in replacement therapy for adrenal insufficiency and as an anti-inflammatory agent. Cortisone itself is inactive. It is converted in the liver to the active metabolite HYDROCORTISONE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p726)
