Reaction Steps

Cyclohexane is poured into the microencapsulation reactor. Then, under continuous stirring, fexofenadine HCl, ethylcellulose (EC) and polyethylene are added. The mixture is heated and then cooled down. Microcapsules are recovered, and then washed (one or more times), filtered, and dried over night (about 16 h) in a fume hood or in a hood at 40° C. The powder is sieved through a 300 μm opening sieve.
