DEFINITION

Classification: 424/682

Aluminum, calcium, or magnesium element, or compound containing:

(under subclass 600) Compositions which contain aluminum, magnesium or calcium in a free metallic state or as part of an inorganic compound.

(1) Note. Many compounds of aluminum calcium in magnesium are characterized as carriers or fillers in a medicinal composition while in other documents the same compound is described as an active ingredient. In this and the following subclasses doubt should always be resolved in favor of classifying the compound as an active ingredient absent a clear showing to the contrary.
