Fusidic acid is a anti-bacterial agent, initially isolated from Fusidium coccineum by Godtfredsen et al (Leo Pharma) in 1960. It is discussed that fusidic acid exerts its anti-microbial effect by inhibiting bacterial elongation factor G, thus suppressing the protein synthesis. Fusidic acid is widely used in Europe under the names Fucidin H(fusidic acid / hydrocortisone acetate), Fucidin (fusidic acid / sodium fusidate) and Fucicort (fusidic acid / betamethasone valerate) for the treatment of primary/secondary skin infections and inflammatory dermatoses.

Curative
FUCIDIN

Approved Use

For use in the treatment of primary and secondary skin infections caused by sensitive strains of Staphylococcus aureus, Streptococcusspp and Corynebacterium minutissimum. Primary skin infections that may be expected to respond to treatment with FUCIDIN OINTMENT (sodium fusidate) and CREAM (fusidic acid) include: impetigo contagiosa, erythrasma and secondary skin infections such as infected wounds and infected burns.
Curative
FUCICORT

Approved Use

FUCICORT is indicated in inflammatory dermatoses where bacterial infection is present or likely to occur. Inflammatory dermatoses include atopic eczema, discoid eczema, seborrheic dermatitis, contact dermatitis, lichen simplex chronicus, psoriasis, discoid lupus erythematosus

Sample Use Guides

A small amount of fucidin ointment(sodium fusidate) or cream (fusidic acid) should be applied to the lesion 3 or 4 times daily until favourable results are achieved. Futicort cream (fusidic acid / betamethasone valerate) is applied 2 times daily.
Route of Administration: Topical
In vitro fusidic acid inhibited S. aureus (minimum inhibitory concentration [MIC], 0.25 ug/mL), Micrococcus luteus (MIC, 0.25–0.5 ug/mL), Corynebacterium spp. (MIC, 0.06–0.12 ug/mL), Moraxella catarrhalis (MIC, 0.06–0.12 ug/mL), and Neisseria meningitidis (MIC, 0.12–0.25 ug/mL).
