Examples of preservatives are phenylmercuric nitrate or acetate (0.002% w/v), chlorhexidine acetate (0.01 % w/v), thiomersal (0.01 % w/v) and benzalkorrium chloride (0.01 % w/v). Chlorocresol is too toxic to the comeal epithehum, but 8-hydroxyquinoline and thiomersal may be used in specific instances. The principal considerahon in relation to antimicrobial properties is the activity of the bactericide against Pseudomonas aeruginosa, a major source of serious nosocomial eye infections. Although benzal-konium chloride is probably the most active of the recommended preservatives, it cannot always be used because of its incompatibility with many compounds commonly used to treat eye diseases, nor should it be used to preserve eye-drops containing anaesthetics. Since benzalkonium chloride reacts with natural mbber, silicone or butyl rabber teats should be substituted. Since silicone mbber is permeable to water vapour, products should not be stored for more than 3 months after manufacture. As with all mbber components, the mbber teat should be pre-equilibrated with the preservative prior to... 

Optimal antibiotic therapies for gram-negative bacillary meningitis have not been fully defined. Meningitis caused by Pseudomonas aeruginosa is initially treated with ceftazidime or cefepime, piperacillin + tazobactam, or meropenem plus an aminoglycoside, usually tobramycin. 

Newer examples of aminoglycoside antibiotics include amikacin, neomycin (Neosporin, Cortisporin), and tobramycin (TOBI, TobraDex). Injectable tobramycin is used in the treatment of serious infections at many body sites. It has also been formulated in an inhalable dosage form that has a very specific use to treat cystic fibrosis patients having Pseudomonas aeruginosa lung infections. In the form suitable for inhalation by the patient, it delivers the antibiotic directly to the site of infection.

If it is decided to treat an upper RTI in general 5-7 days treatment suffices. In lower RTI generally 10-14 days are recommended. Two to three weeks of treatment is advised for Staphylococcus aureus, Legionella pneumophila. Pseudomonas aeruginosa, Pneumocystis jiroveci (formerly carinii) and severe aspiration-pneumonia. Tuberculosis, actinomycosis, nocardiosis, aspergillosis, melioidosis and anaerobic lung abscesses require many months of treatment.
