SYNONYMS: Glycerina (Br.), Glycerines (Br.), Glycerata, Glyceroles, Glycerolata, Glycerols, Glycerates, Glycemates.
By this class of preparations is generally understood solutions of medicinal substances in glycerin, although in certain instances the various Pharmacopoeias deviate to an extent. The term Glycerita as here applied to fluid glycerines, or solutions of agents in glycerin, is preferable to the ordinary names, "glyceroles," "glycerates," or "glycemates," etc., and includes all fluid preparations of the kind referred to, whether for internal administration or local application. Many solutions of glycerin or glycerin and water, are apt upon standing to develop microscopic cryptogams, unless a certain proportion of alcohol is added to the solutions. On this account, it is better to prepare many members of this class of solutions in small quantity at a time, and only as they are wanted (see Lotions and Plasmae).
Related Preparation.—GLYCELOEUM. This was introduced, in 1867, by T. E. Groves. Take almond meal (fine), ½ ounce; glycerin, 1 ounce; olive oil, 3 ounces. Triturate the meal with the glycerin and gradually incorporate the oil with the mixture. This semi-gelatinous, pasty mass may be made into emulsions by gradually adding water to it. Powders may also be incorporated with it. Oleoresins and essential oils may be employed as substitutes, wholly or in part.
