 Arabica coffee ground nanoparticles gel is known to possess good physicochemical properties and high phenolic contents in which the phenolics are famous for their anti-inflammatory activities.

 : This study aimed to investigate the anti-inflammatory activities of the arabica coffee ground nanoparticles gel on carrageenan-induced male mice for 6 h. The positive control was commercial medicine (Voltaren gel), and the control negative was base gel.

 The inflammatory inhibition of arabica coffee ground nanoparticles gel is determined by measuring the edema volume of the carrageenan-induced mice foot using a plethysmometer. Anti-inflammatory activities of arabica coffee ground nanoparticles gel were optimized using Box-Behnken Design of the response surface methodology.

 The anti-inflammatory activities or inflammatory inhibition of arabica coffee ground nanoparticles gel was determined by measuring the edema volume of the carrageenan-induced mice foot. The increase of edema volume of the mice foot from the first to 180th min was caused by the release of inflammation mediator such as histamine, prostaglandins, bradykinins, and serotonin on the tissue; meanwhile, at the 240th min, the edema of the mice foot experienced a decrease due to the inhibition of prostaglandins synthesis to the tissue. The obtained results indicated that the arabica coffee ground nanoparticles gel has average value of anti-inflammatory activities of 27.75%. The obtained optimum formulation is 0.500% Carbopol 940, 0.400% triethanolamine, and 2.313% nanoparticle, giving 29.360% and 29.670% for the predicted and experimental inflammatory inhibition values, with 0.812 desirability value, respectively.

 The Box-Behnken design can be used to determine the optimal gel formulation of arabica coffee grounds for inflammatory inhibition.
