For a variety of reasons, the historical dosing of colistin has been challenged by newer pharmacokinetic analyses. This calculator uses recent pharmacokinetic modeling data and recommendations published in by Garonzik et al.

These samples were used to develop a population pharmacokinetic model and dosing recommendations. This calculator implements the dosing recommendations made by Garonzik et al.

Because CMS is primarily renally eliminated whereas colistin is primarily non-renally eliminated , renal function significantly influences the extent of CMS converted to colistin in vivo. Decreased renal function results in decreased CMS elimination, which leads to increased amounts of CMS available in the body for conversion to colistin and, thus, higher colistin plasma concentrations.

Conversely, very good renal function leads to a smaller percentage of CMS being converted to colistin, resulting in lower colistin plasma concentrations.

Pharmacology

This complex pharmacokinetic relationship between prodrug and active moiety is one of the reasons for the current debate regarding optimal CMS dosage regimens.

The Css,avg should be based on the organism MIC, site, and severity of infection. Consultation with an infectious diseases specialist is strongly recommended for assistance with determination of target Css,avg.

Due to the slow conversion of CMS to colistin in vivo, it may take a few hours to days to reach target Css,avg in plasma and continuation of a maintenance regimen without a loading dose may result in accumulation of colistin plasma concentrations over time. Therefore, a loading dose of CMS is recommended. Combination therapy may also help minimize the emergence of resistance in gram-negative isolates harboring colistin heteroresistance, e.

In the last few years, with a paucity of available antibiotic option, interest has been renewed in the old antibiotic, polymyxins, as salvage therapy in the management of infections caused by MDR gram-negative pathogens including Pseudomonas, Acinetobacter, Klebsiella, and Enterobacter species [ 1 - 3 ]. Polymyxins are group of cationic polypeptide antibiotics, having five different compounds polymyxin A-E [ 4 ]. In , colistin Polymyxin E was first time isolated from Bacillus polymyxa var.

Only polymyxin E Colistin and polymyxin B have been used in clinical practice since their discovery [ 1 , 2 ]. Both, colistin and polymyxib B, are produced by the soil bacterium Bacillus spp.

Table 1 History of colistin Full size table Clinical experience is more with colistin in comparison to polymyxin B due to its wider use.

After introduction in clinical practice, uses of parenteral colistin were gradually waned worldwide within two decades due to reported severe toxicities, while its topical uses continued [ 2 - 4 ].

So, era of colistin as intravenous use could be divided in three phases: — against gram-negative infection; — for MDR gram-negative pathogens in cystic fibrosis; and onwards: nosocomial infection due to MDR gram-negative pathogens. In this presented descriptive review, we looked in published literature for the use of colistin in lung infection in critically ill patients without cystic fibrosis.

Each molecule has a cationic polypeptide ring with a lipophilic fatty acid chain. Figure 1 Descriptive and chemical structure of colistin.

B Chemical structure of colistin. Full size image Spectrum of activity Colistin has excellent bactericidal activity against most gram-negative bacilli, while no activity against all gram-positive and most anaerobes except few like Prevotella spp.

Colistin has also been reported to be potentially active against several Mycobacterium spp. Table 2 Spectrum of activity of colistin Full size table Mechanism of action and resistance The targets site for colistin is lipopolysaccharide LPS component of the outer membrane of gram-negative bacteria.

In there, colistin interacts with the lipid A component of the LPS, displacing the calcium and magnesium bridges that stabilize the LPS, leading to permeabilizing the bacterial outer membrane that can be described as detergent-like mechanism of action [ 4 ].

By another postulated mechanism, polycationic polymyxin binds to anionic phospholipid; this contact promotes lipid exchange between inner and outer membrane results in the loss of phospholipid composition leading to an osmotic imbalance resulting in lytic cell death [ 4 ]. The majority of mechanisms of resistance to colistin are based on modifications to the lipid A portion of LPS of gram-negative bacteria, like Pseudomonas aeruginosa and Escherichia coli, that reduces its net negative charge resulting in less electrostatic interaction with positively charged colistin molecule [ 1 , 4 ].

While in Klebsiella pneumoniae, the mechanism of resistance to colistin is because of increased production of capsule polysaccharide [ 8 ]. Susceptibility test and heteroresistance Antimicrobial susceptibility testing for colistin can be performed using either diffusion disc diffusion, prediffusion test, or epsilometer test E-test or dilution techniques broth microdilution or agar dilution [ 6 ].

Use of colistin has been increasing in the recent past and newer studies have shown lesser toxicity and good efficacy. Xylistin package insert information updated Sept Dosing regimens differ in package inserts from different manufacturers and in.Multiple other cases were reported from other Indian hospitals. No standards for measuring colistin sensitivity are given in the US. But at present, studies evaluating clinical outcome with these high dosage of colistin are lacking.

Each country has different generic preparations of colistin, and the recommended dose depends on the manufacturer. Using the other Dispensing Pin, insert the pointed end into one colistimethate vial.
