The present invention includes a container which has a plurality of compartments each configured to contain a plurality of dosages of a different medication. The present invention also relates to a process for the preparation of stable aqueous oral formulation of alendronate sodium. The two rotating bodies can rotate jointly around the spool axis, at least when the second rotating body is located in its first end position. The receptacle includes a rail groove in which, when the external cylinder is rotated, the projection moves the plug 1 in a direction along which the plug is away from the receptacle.
