CA2218370A1 — Chewable tablet with effervescent action

USPTO Abstract

The chewing tablets proposed contain a small amount of effervescent agent (which gives a pleasant fizzy feeling in the mouth), active substances and fillers in amounts chosen so that the tablets will nevertheless dissolve, with the exception of any insoluble or poorly soluble active substances, in 100 ml of water at 15 to 20°C in less that 120, preferably 90, seconds. This is achieved by virtue of the fact that the acid and/or carbonate particles in the effervescent agent are coated with a preferably readily, i.e. rapidly, soluble hydrocolloid and/or the active substance is free of encapsulation agents and the tablet mixture is free of lubricants. Tablet weight is 600 to 1500 mg, preferably only 700 to 1200 mg.
