Occasionally it is necessary to add solvent to the contents of a container just prior to use, usually because of instability of some drugs in the diluted form. Thus, a solid diluted to yield a suspension is called [DRUG] for Suspension; a solid dissolved and diluted to yield a solution is called [DRUG] for Solution; and a solution or suspension diluted to yield a more dilute form of the drug is called [DRUG] Oral Concentrate. After dilution, it is important that the drug be homogeneously dispersed before administration.
