Abstract
Preparations of penicillin salts difficulty soluble in water, which preparations contain water, or in which the penicillin salt in the course of production comes into contact with water, are stabilized by dissolving in the aqueous phase the cation of the penicillin salt so that there is present an excess of the cation of the penicillin salt over and above that combined in the penicillin salt. Such salts are procaine penicillin and aluminium penicillin. The aqueous solution may contain other substances such as hydrophyllic colloids, e.g. carboxymethyl cellulose, carboxymethyl starch, alkali metal salts of alginic acid and pectins and amylopectin, alkali metal salts, e.g. sodium chloride, and preservatives, e.g. methyl p-hydroxybenzoate. An example is given of a procaine penicillin injection in which the said salt is suspended in an aqueous solution of procaine hydrochloride, sodium carboxymethyl cellulose, sodium chloride and methyl p-hydroxybenzoate.ALSO:Preparations of penicillin salts difficultly soluble in water, which preparations contain water, or in which the penicillin salt in the course of production comes into contact with water, are characterized in that to the aqueous phase is added the cation of the penicillin salt so that there is present an excess of the cation of the penicillin salt over and above that combined in the penicillin salt. Such salts are procaine penicillin and aluminium penicillin. The aqueous solution may contain other substances such as hydrophillic colloids, e.g. carboxymethyl cellulose carboxymethyl starch alkali metal salts of alginic acid and pectins and amylopectin, alkali metal salts, e.g. sodium chloride and preserving agents, e.g. methyl p-hydroxybenzoate. An example is given of a procaine penicillin injection in which the said salt is suspended in an aqueous solution of procaine hydrochloride, sodium carboxymethyl cellulose, sodium chloride and methyl p-hydroxybenzoate. The preparations may be water-containing ointments, injections and lozenges.
