Reaction Steps
A premix is prepared of 440 g of azelastine-HCl, 360 mg of micro crystalline cellulose and 200 g of talcum. This premix together with 6000 g of lactose monohydrate, 2870 g of microcrystalline cellulose and 100 g of highly disperse silicon dioxide are passed through a sieve and homogenized in a sutable mixer. 30 g of magnesium stearate are sieved into the mixture so obtained and the resulting mixture is homogenized one more time. The mass so obtained is pressed into tablets weighing 100 mg having a diameter of 6 mm and a radius of curvature of 5.5 mm.
