Sodium fusidate

Overdose

Standard powder sample; Substance-powderCream for external use; Ointment for external use

Overdose is unlikely.

Unless hypersensitivity to Sodium fusidate or any of the excipients exist, accidental ingestion of Sodium fusidate 20mg/g cream is unlikely to cause any harm. The total quantity of Sodium fusidate (30g Sodium fusidate 20mg/g cream contains 600mg Sodium fusidate) will usually not exceed the approved total daily oral dose of Sodium fusidate containing products except in children aged less than 1 year and weighing ≤10kg.

Although in this instance a child of this particular age group is unlikely to ingest a whole tube of Sodium fusidate 20mg/g cream. The concentration of the excipients is too low to constitute a safety risk.

Therapeutic indications

Standard powder sample; Substance-powderCream for external use; Ointment for external use

Treatment of non-severe, superficial, non-extensive, primary skin infections caused by microorganisms that are sensitive to Sodium fusidate, especially of infections caused by Staphylococcus.

Primary skin infections that may be expected to respond to treatment with Sodium fusidate applied topically include: impetigo contagiosa, superficial folliculitis, sycosis barbae, paronychia and erythrasma.

Consideration should be given to official guidance on the appropriate use of antibacterial agents..

Sodium fusidate 20 mg/g cream is indicated either alone or in combination with systemic therapy, in the treatment of primary and secondary skin infections caused by sensitive strains of Staphylococcus aureus, Streptococcus spp and Corynebacterium minutissimum. Primary skin infections that may be expected to respond to treatment with fusidic acid applied topically include: impetigo contagiosa, superficial folliculitis, sycosis barbae, paronychia and erythrasma; also such secondary skin infections as infected eczematoid dermatitis, infected contact dermatitis and infected cuts/abrasions.

Pharmacodynamic properties

Standard powder sample; Substance-powderCream for external use; Ointment for external use

Pharmacotherapeutic group: other antibiotics for topical use, ATC code: D06AX01

Active mechanism:

Sodium fusidate belongs to a unique group of antibiotics, the fusidanes, which act to inhibit bacterial protein synthesis by blocking the lengthening of factor G. This is to prevent it from associating with ribosomes and GTP, thus preventing energy supply to the synthesis process.

As it is the only type of drug available in this family of drugs, there have been no reports of cross resistance to Sodium fusidate.

Resistance mechanism(s):

Resistance for Sodium fusidate can vary geographically and information about local resistance patterns should be obtained through a local microbiology laboratory. In general, resistance occurs in 1-10 % of Staphylococcus aureus and 10-20 % of coagulase negative staphylococcus. Cross-resistance between Sodium fusidate hydrophilic cream 20 mg/g and other antibiotics has not been reported.

Breakpoints:

The following MIC values are recommended to distinguish sensitive and non-sensitive germs: S ≤ 1 µg/ml and R > 1 µg/ml. This breakpoint should be used for the systemic use of Sodium fusidate. In general, no breakpoints are established for the topical use of antibiotics.

Sensitivity:

The sensitivity of organisms to Sodium fusidate is based on the in vitro sensitivity and plasma concentrations that are achieved after systemic therapy. Local treatment causes higher peak concentrations as compared to plasma. However, it is not known how the kinetics of the cream after local application may change the effectiveness of the cream.

Commonly susceptible species

Staphylococcus aureus and Staphylococcus epidermis (including methycillin resistant and beta lactamase producing strains);

Corynebacterium minutissimum; Clostridium spp.; Peptococcus spp.;

Peptostreptococcus spp.; Neiseria spp.; Bacteroides fragilis.

Inherently resistant organisms

Streptococcus pyogenes; Streptococcus pneumoniae; Streptococci viridans; most gram negative bacilli including Haemophilus influenza; Enterobactericeae; Pseudomonas spp.; Escherichia coli and Klebsiella pneumoniae.

Pharmacotherapeutic group: Other antibiotics for topical use, ATC code: D06AX01

Fusidic acid is a potent antibacterial agent. Fusidic acid and its salts show fat and water solubility and strong surface activity and exhibit unusual ability to penetrate intact skin. Concentrations of 0.03 - 0.12 mcg fusidic acid per ml inhibit nearly all strains of Staphylococcus aureus. Topical application of fusidic acid is also effective against streptococci, corynebacteria, neisseria and certain clostridia.

Pharmacokinetic properties

Standard powder sample; Substance-powderCream for external use; Ointment for external use

In Vitro studies show that Sodium fusidate can penetrate intact human skin. The degree of penetration depends on factors such as the duration of exposure to Sodium fusidate and the condition of the skin. Sodium fusidate is excreted mainly in the bile with little excreted in the urine.

Special warnings and precautions for use

Standard powder sample; Substance-powderCream for external use; Ointment for external use

Bacterial resistance has been reported to occur with the use of Sodium fusidate.

Extended or recurrent use may increase the risk of developing contact sensitisation.

When Sodium fusidate 20 mg/g cream is used on the face, care should be taken to avoid the eyes, because Sodium fusidate can cause irritation of the conjunctiva.

Sodium fusidate 20 mg/g cream contains butylhydroxyanisole, cetyl alcohol and potassium sorbate which may cause local skin reactions (e.g. contact dermatitis). Butylhydroxyanisole may also cause irritation to the eyes and mucous membranes.

Bacterial resistance among staphylococcus aureus has been reported to occur with the use of topical Sodium fusidate. As with all antibiotics, extended or recurrent use may increase the risk of developing antibiotic resistance.

Extended or recurrent use may increase the risk of developing contact sensitisation.

Sodium fusidate cream contains butylhydroxyanisole, cetyl alcohol and potassium sorbate. These excipients may cause local skin reactions (e.g. contact dermatitis). Butylhydroxyanisole may also cause irritation to the eyes and mucous membranes. Sodium fusidate cream should therefore be used with care when applied in the proximity of the eyes.
