BACKGROUND
A major clinical challenge in treating allergic contact dermatitis (ACD) is that the first line of treatment is based on the use of corticosteroids. In this study, we aimed to develop a formulation that is devoid of steroids.
METHODS
We used mouse ears treated with dinitrofluorobenzene (DNFB) to induce ACD. The efficacy of the test formulation to ameliorate and to prevent induced ACD was determined.
RESULTS
To treat this experimentally induced ACD, we developed a formulation containing BIPxine (a mixture of Rosa moschata and Croton lechleri (antioxidants) and Aloe vera and D-panthenol (moisturizers), and hydroglycolic solutions of disodium cromoglycate. Our results show that clear inhibition of ACD took place. The target of this formulation was PAR-2, TRPV4, and other mediators of the inflammatory and pain responses. However, this formulation must be evaluated in other models besides the mouse to confirm its effectiveness.
CONCLUSIONS
The formulation presented here may provide new ACD therapies that do not involve the use of corticosteroids.
