    Abstract

    A unit-dose tablet composition comprising a surfactant, a builder, a filler and an effervescent agent selected from organic acids wherein at least 90% wt. of the effervescent agent is coated with triglyceride oil.

    Claims

    1. A unit-dose tablet composition comprising a surfactant, a builder, a filler and an effervescent agent selected from organic acids wherein at least 90% wt. of the effervescent agent is coated with triglyceride oil.

    2. A unit dose tablet composition according to claim 1 wherein the effervescent agent is selected from citric acid, tartaric acid, fumaric acid, malic acid, adipic acid, succinic acid, and mixtures thereof.

    3. A unit dose tablet composition according to claim 1, wherein the effervescent agent comprises from 1 to 20% wt. of the composition.

    4. A unit dose tablet composition according to claim 1, wherein the filler comprises from 5 to 40% wt. of the composition.

    5. A unit dose tablet composition according to claim 1, wherein the surfactant comprises from 2 to 70% wt. of the composition.

    6. A unit-dose tablet composition according to claim 1, further comprising an effervescent selected from carbonate salts selected from sodium carbonate, potassium carbonate, calcium carbonate, sodium bicarbonate, potassium bicarbonate, calcium carbonate, calcium bicarbonate and magnesium carbonate as well as mixtures thereof.

    7. A unit dose tablet composition according to claim 1, further comprising a water-soluble salt.

    8. A unit dose tablet composition according to claim 7 wherein the water-soluble salt has a solubility in distilled water of in the range of 0.5 g/100 mL to 75 g/100 mL at 25? C.

    9. A unit dose tablet composition according to claim 7, comprising 0.5 to 20 wt. % water soluble salt.

    10. A unit dose tablet composition according to claim 1, wherein the triglyceride oil comprises from 5 to 35% wt. of the coated effervescent agent.
