Neomycin
About NeomycinAn aminoglycoside, Antibiotic, Ammonium Detoxicant.Mechanism of Action of NeomycinThis aminoglycoside cause protein synthesis inhibition by "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.Pharmacokinets of NeomycinAbsorption- Poorly absorbed after oral administration

About Fluocinolone acetonideA synthetic hydrocortisone derivative, Vasoprotective ,reduce skin inflammation.Mechanism of Action of Fluocinolone acetonideFluocinolone is a topical high potency glucocorticoid.
The drug exerts its pharmacological action by penetrating and binding to cytoplasmic receptor protein and causes a structural change in steroid receptor complex. This structural change allows it`s migration in to the nucleus and then binding to specific sites on the DNA which leads to transcription of specific m-RNA and which ultimately regulates protein synthesis. It exerts highly selective glucocorticoid action. It stimulates the enzymes needed to decrease the inflammatory response.
The drug exerts anti-inflammatory and immunosuppressant actions as follows: - 1) Induce lipocortins in macrophages, endothelium, and fibroblasts which inhibits Phospholipase A2 and thus decreases the production of Prostaglandins, leukotrienes (LT), and platelet activating factor, 2) Causes negative regulation of genes for cytokines in macrophages, endothelial cells and lymphocytes and thus decreases the production of interleukins (IL-1, IL-2, IL-3, IL-6), TNF-?, GM-CSF (granulocyte macrophage colony stimulating factor), Gama interferon and suppresses fibroblast proliferation and T-lymphocyte functions and interferes chemo taxis. 3) Decreases the production of acute phase reactants from macrophages and endothelial cells and interferes complement function. 4) Decreases the production of ELAM-1(Endothelial leukocyte adhesion molecule-1) and ICAM-1(intracellular adhesion molecule-1) in endothelial cells. 5) Inhibit IgE mediated histamine and LT-C4 release from basophiles and the effects of antigen-antibody reaction is not mediated 6) Reduces the production of collagenase and stromolysin and thus prevents tissue destruction.
Fluocinolone also has immunosuppressant and antimitotic actions.
