Title: A penicillin salt and therapeutic preparations containing same
IPC: C07D499/22
Filed: 1957-03-14
Abstract: The invention relates to a salt of oleandomycin or chloro-oleandomycin with penicillin.  The penicillin is any penicillin but is particulaly penicillin G or penicillin V.  The salt is produced by reacting the full acid penicillin with the free base olenadomycin or chloro-oleandomycin in a solvent which may be an oxygenated or chlorinated aliphatic organic solvent containing up to six carbon atoms such as ethyl formate, methyl propionate, ethanol, methanol, acetone, methyl isobutyl ketone, chloroform, carbon tetrachloride or ethyl acetate, which is preferred.  The temperature is 0 DEG  to 30 DEG  C., especially 20 DEG  C. A salt of penicillin, e.g. sodium salt, may be reacted with a salt of oleandomycin or chloro-oleandomycin, e.g. hydrochloride in an aqueous medium.  In one example, oleandomycin chloroform adduct, obtained by crystallization of oleandomycin from a chloroform solution, is dissolved in ethyl acetate and added slowly to a solution of penicillin G in ethyl acetate at 20 DEG  C. in order to crystallize the penicillin G-oleandomycin salt therefrom.  The melting point, optical rotation and infra-red absorption spectrum of the oleandomycin salts of penicillin G and penicillin V are given.  The salts are used medicinally (see Group VI). Specifications 779,257 and 799,208 are referred to.ALSO:A therapeutic composition comprises a mixture of a penicillin antibiotic with an oleandomycin antibiotic, as such, or with the further addition of a pharmaceutical carrier, the penicillin activity of the composition being from 10 to 90 per cent of the total antibiotic content.  The penicillin antibiotic is any penicillin, e.g. penicillin G, penicillin F or penicillin V in any therapeutically effective form such as the sodium and potassium salt. The oleandomycin antibiotic is oleandomycin or chloro-oleandomycin in any therapeutically effective form such as the hydrochloride and phosphate.  In addition to the individual antibiotics, a salt of penicillin with oleandomycin or chloro-oleandomycin (see Group IV (b)) may be included in the compositions to produce slow release of the antibiotics, penicillin G-oleandomycin being particularly effective.  The compositions may be administered (a) orally as tablets or capsules containing excipients such as starch, milk sugar and clay, or (b) parenterally as sterile solutions or dispersions containing saline or glucose to provide isotonic solutions. Specifications 779,257, [Group IV (b)], and 799,208 are referred to.
