The present invention relates to rapidly disintegrating tablets intended to be used as orodispersible tablets or dispersible tablets. They are ingested either by dispersing directly in the mouth or in water. The tablets include silicified microsrystalline cellulose. They are especially suitable for antibiotics. These tablets are also suitable for use in pediatric patients in the age above 3 years. For pediatric patients under 3 years the same tablets can be used as dispersible tablets. Rapidly disintegrating tablets which contain amoxicillin and clavulanic acid are also described.
