Neomycin Sulphate, Polymixin B sulphate, Prednisolone acetate
Indications
Neomycin Sulphate, Polymixin B sulphate, Prednisolone acetate is used for:
NEOMYCIN
Topical uses include treatment for superficial eye infections caused by susceptible bacteria (used in combination with other antiinfectives), treatment of otitis externa caused by susceptible bacteria, treatment or prevention of bacterial infections in skin lesions, and use as a continuous short-term irrigant or rinse to prevent bacteriuria and gram negative rod bacteremia in abacteriuric patients with indwelling catheters. May be used orally to treat hepatic encephalopathy, as a perioperative prophylactic agent, and as an adjunct to fluid and electrolyte replacement in the treatment of diarrhea caused to enteropathogenic e. Coli (epec)
POLYMYXIN B SULFATE
For treatment of infections of the urinary tract, meninges, and blood stream, caused by susceptible strains of pseudomonas aeruginosa
PREDNISOLONE
For the treatment of primary or secondary adrenocortical insufficiency, such as congenital adrenal hyperplasia, thyroiditis. Also used to treat psoriatic arthritis, rheumatoid arthritis, ankylosing spondylitis, bursitis, acute gouty arthritis and epicondylitis. Also indicated for treatment of systemic lupus erythematosus, pemphigus and acute rhematic carditis. Can be used in the treatment of leukemias, lymphomas, thrombocytopenia purpura and autoimmune hemolytic anemia. Can be used to treat celiac disease, insulin resistance, ulcerative colitis and liver disorders

Mechanism of Action
NEOMYCIN
Aminoglycosides like neomycin "irreversibly" bind to specific 30s-subunit proteins and 16s rrna. Specifically neomycin binds to four nucleotides of 16s rrna and a single amino acid of protein s12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16s rrna of 30s subunit. This region interacts with the wobble base in the anticodon of trna. This leads to interference with the initiation complex, misreading of mrna so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes
POLYMYXIN B SULFATE
Polymyxin b sulfate has a bactericidal action against almost all gram-negative bacilli except the proteus group. Polymyxin b sulfate interacts with the lipopolysaccharide of the cytoplasmic outer membrane of gram-negative bacteria, altering membrane permeability and causing cell death. It does not need to enter the cell
PREDNISOLONE
Glucocorticoids such as prednisolone can inhibit leukocyte infiltration at the site of inflammation, interfere with mediators of inflammatory response, and suppress humoral immune responses. The antiinflammatory actions of glucocorticoids are thought to involve phospholipase a2 inhibitory proteins, lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes. Prednisolone reduces inflammatory reaction by limiting the capillary dilatation and permeability of the vascular structures. These compounds restrict the accumulation of polymorphonuclear leukocytes and macrophages and reduce the release of vasoactive kinins. Recent research suggests that corticosteroids may inhibit the release of arachidonic acid from phospholipids, thereby reducing the formation of prostaglandins. Prednisolone is a glucocorticoid receptor agonist. On binding, the corticoreceptor-ligand complex translocates itself into the cell nucleus, where it binds to many glucocorticoid response elements (gre) in the promoter region of the target genes. The dna bound receptor then interacts with basic transcription factors, causing an increase or decrease in expression of specific target genes, including suppression of il2 (interleukin 2) expression
