Background

Bacitracin is a combination of at least 9 bacitracins.^2,3 60-80% of commercially prepared bacitracin is bacitracin A.³ The bacillus that produces bacitracin was first isolated from a knee scrape in 1945 from the knee wound of a child named Margaret Tracy.³

Bacitracin was granted FDA approval on 29 July 1948.^4,9

Pharmacology

Indication

Bacitracin is indicated in topical formulations for acute and chronic localized skin infections.⁴ Occasionally, it is also used intramuscularly for infantile streptococcal pneumonia and empyema.⁴ Bacitracin is also formulated as an ointment with neomycin and polymyxin B for over the counter use.^4,10 A bacitracin ointment formulated with neomycin and polymyxin B along with hydrocortisone is indicated for the treatment of corticosteroid responsive dermatoses with secondary infection.¹¹

Pharmacodynamics

Bacitracin is a mixture of polypeptides that prevent the formation of the bacterial cell wall and oxidatively cleave DNA.¹ It has a short duration of action as it must be given every 3 to 4 hours topically.^10,11 Bacitracin is nephrotoxic when given intramuscularly and may lead to renal failure.⁴

Mechanism of action

Bacitracin binds to a divalent metal ion such as Mn(II), Co(II), Ni(II), Cu(II), or Zn(II).¹ These complexes bind C₅₅-isoprenyl pyrophosphate, preventing the hydrolysis of a lipid dolichol pyrophosphate, which finally inhibits cell wall synthesis.¹ Bacitracin metal complexes also bind and oxidatively cleave DNA.¹

AC55-isoprenyl pyrophosphate	antagonist	Gram positive and gram negative bacteria
AInsulin-degrading enzyme	inhibitor	Humans
UAlpha-2-macroglobulin	inhibitor	Humans

Absorption

Topical, ophthalmic, and oral formulations of bacitracin are poorly absorbed systemically.^4,7 Intramuscular bacitracin is readily and completely absorbed.¹³

Volume of distribution

Data regarding the volume of distribution of bacitracin in humans is not readily available.⁴

Protein binding

Data regarding the protein binding of bacitracin in humans is not readily available.⁴

Metabolism

Data regarding the metabolism of bacitracin in humans is not readily available.⁴ Because bacitracin is a protein it is expected to be metabolized into smaller polypeptides and amino acids.⁵ However, the structure of bacitracin may afford it some protection from the action of proteases.¹

Route of elimination

Bacitracin is mainly excreted renally with 87% of and intramuscular dose being recovered in the urine after 6 hours.⁶

Half-life

Data regarding the half life of bacitracin in humans is not readily available.⁴

Clearance

Data regarding the clearance of bacitracin in humans has not been well studied.⁴ A study of 9 subjects in 1947 shows a renal clearance of 105-283mL/min with an average renal clearance of 159mL/min.⁶

Toxicity

The oral LD₅₀ of bacitracin in rats is >2000mg/kg.¹²

Specific data regarding bacitracin overdoses is not readily available.⁸ An overdose of bacitracin may lead to nephrotoxicity⁴ and patients should be treated with supportive measures.
