Preparations pectin used as drug carrier

The invention concerns pectic preparations which comprise at least one pectin associated with a complex composition comprising firstly an effervescent pair which easily disperses the pectin in water and hydrates it and regulates the gellification process irrespective of the hardness of the water used for the suspension, and secondly a mixture of compounds which provide the calcium ions necessary for the formation of the gel in an acid medium, together with magnesium ions regulating the kinetics of the calcium availability.
