Neomycin Eye Ointment 

Action and use

Aminoglycoside antibacterial.

Definition

Neomycin Eye Ointment is a sterile preparation containing Neomycin Sulphate in a suitable basis.


The eye ointment complies with the requirements stated under Eye Preparations and with the following requirements.

Identification

Carry out the method for thin-layer chromatography, Appendix III A, using a silica gel precoated plate (Merck silica gel 60 plates are suitable) and a mixture of 20  volumes of chloroform, 40  volumes of 13.5m ammonia and 60  volumes of methanol as the mobile phase. Apply separately to the plate 1 µl of each of the following solutions. For solution (1) disperse a quantity of the eye ointment containing 14,000  IU in 100  ml of chloroform, extract with 5  ml of water and use the aqueous extract. Solution (2) contains 0.4% w/v of neomycin sulphate EPCRS in water. Solution (3) is a mixture of equal volumes of solutions (1) and (2). After removal of the plate, allow it to dry in air, spray with a 1% w/v solution of ninhydrin in butan-1-ol and heat at 105° for 2  minutes. The principal red spot in the chromatogram obtained with solution (1) corresponds to that in the chromatogram obtained with solution (2) and the principal red spot in the chromatogram obtained with solution (3) appears as a single spot.

Tests

Neamine

Carry out the method for thin-layer chromatography, Appendix III A, using silica gel H as the coating substance and a freshly prepared 3.85% w/v solution of ammonium acetate as the mobile phase. Apply separately to the plate 2 µl of each of the following solutions. For solution (1) disperse a quantity containing 14,000  IU in 20  ml of chloroform, shake gently with 8  ml of water, allow the layers to separate and use the aqueous layer. Solution (2) contains 0.005% w/v of neamine EPCRS. After removal of the plate, dry it in a current of warm air, heat at 110° for 10  minutes and spray the hot plate with a solution prepared immediately before use by diluting sodium hypochlorite solution with water to contain 0.5% w/v of available chlorine. Dry in a current of cold air until a sprayed area of the plate below the line of application gives not more than a very faint blue colour with one drop of a 0.5% w/v solution of potassium iodide in starch mucilage; avoid prolonged exposure to cold air. Spray the plate with a 0.5% w/v solution of potassium iodide in starch mucilage. Any spot corresponding to neamine in the chromatogram obtained with solution (1) is not more intense than the spot in the chromatogram obtained with solution (2).


Neomycin C

Complies with the test described under Neomycin Eye Drops but preparing solution (2) in the following manner. Disperse a quantity of the eye ointment containing 3500  IU in 20  ml of petroleum spirit (boiling range, 120° to 160°), add 5  ml of 0.02m sodium tetraborate, shake, separate the aqueous layer and centrifuge; proceed as for solution (1) but using 0.5  ml of the separated aqueous layer in place of 0.5  ml of the neomycin sulphate solution.

Assay

Dissolve a quantity containing 3500  IU in 25  ml of chloroform, extract with four 20  ml quantities of sterile phosphate buffer pH 8.0, combine the extracts and add sufficient of the buffer solution to produce 100  ml. Carry out the microbiological assay of antibiotics, Appendix XIV A. The precision of the assay is such that the fiducial limits of error are not less than 95% and not more than 105% of the estimated potency. The upper fiducial limit of error is not less than 90.0% and the lower fiducial limit of error is not more than 115.0% of the stated number of IU per g.

Labelling

The strength is stated as the number of IU (Units) per g.
