Preservation of sodium bicarbonate eye lotion BPC against contamination with Pseudomonas aeruginosa.

BPC (i 968) eye lotions are sterile aqueous solutions which do not contain an antibacterial preservative and which are intended to be used undiluted in first-aid or domiciliary treatment.The fact that the eye lotion does not contain an antibacterial preservative means that the solution, after opening, is limited to being used once only in first-aid treatment or within 24 hours in domiciliary treatment.There may be a case, however, for sodium bicarbonate eye lotion BPC to be so formulated that it can be used as a multiple dose preparation for domiciliary treatment.Pseudomonas aeruginosa (P.aeruginosa) was stated to be the most common contaminantReceivedl fot publitatioio Api 1i6, 197I (ldress fot reprinits: Phairmaceutitcal Mic ro)iology Gt otpl), Plhat mac(y D)epartmttentt, Hetriot-WX'att ULnivet sits IEdibIl)ItrLdi copyright.
