Prescription requirement for polymyxin

FDA approval of polymyxin
Polymyxin has received FDA approval for the treatment of various infections caused by susceptible bacteria.
Active ingredient of polymyxin and mechanism of action
Polymyxin is an antibacterial belonging to a class of antibiotics called polymyxins. The active ingredient in polymyxin B is polymyxin B sulfate. Polymyxins B and E (colistin) are used for the treatment of multidrug-resistant gram-negative bacteria infections (pathogens).
They are part of a larger class of medications called nonribosomal peptides, and work by binding to lipopolysaccharides (LPS) and phospholipids in the bacterial cell membrane, increasing permeability by displacing divalent cations from phosphate groups of outer membrane lipids, leading to leakage of cellular contents and ultimately bacterial cell death. Structurally, colistin and polymyxin B differ by a single amino acid in the peptide ring.
Uses of polymyxin
Polymyxin is an antimicrobial polypeptide, primarily used for the treatment of bacterial infections caused by susceptible organisms, such as strains of multiple drug-resistant isolates, carbapenem-resistant Enterobacteriaceae, Pseudomonas aeruginosa (P. Aeruginosa), Klebsiella pneumoniae, Acinetobacter baumannii, gram-negative bacilli, Escherichia Coli (E. Coli) and most fungi and gram-positive bacteria. Clinical use of polymyxins is for the treatment of infectious diseases of the respiratory tract, urinary tract infections, and skin and soft tissue infections.
Forms of polymyxin
Polymyxin is available in various forms, including intravenous (IV) formulations, topical creams, and ointments. The specific form and strength will depend on the intended use and the formulation of the medication.
Dosage of polymyxin
The dosage regimen of polymyxin will vary depending on the specific infection being treated, the patient’s age and weight, and other factors. Loading doses should be considered for critically ill patients. It is important to follow the dosage instructions provided by your healthcare provider.
Precautions and warnings for polymyxin
- Polymyxin may cause allergic reactions in some individuals. Inform your healthcare provider if you have a history of hypersensitivity to polymyxin or other antibiotics.
- It may interact with certain medications, so it is important to inform your healthcare provider about all the medications you are taking, including prescription drugs, over-the-counter medications, and herbal supplements.
- Polymyxin should be used with caution in patients with pre-existing problems with renal function or renal impairment or hearing impairment.
- It is important to complete the full course of treatment prescribed by your healthcare provider, even if your symptoms improve
- Although polymyxin antibiotics can be given parenterally, they do have an incidence of being neurotoxic and nephrotoxic, and are usually only used as a last resort if other, more modern antibiotics are not effective or are not recommended. They are mainly only used in topical or ophthalmic drugs, in combination with bacitracin and neomycin or tetracycline
Side effects of polymyxin
Polymyxin may cause side effects in some individuals. Common side effects may include:
- Nausea
- Vomiting
- Diarrhea
- Allergic reactions
- Kidney problems
- Hearing problems
The most common adverse effect of intravenous polymyxins is nephro-toxicity. Contact your healthcare provider if you experience severe or persistent side effects.
Interactions with other drugs
