Colistina
Colistina Uses, Dosage, Side Effects, Food Interaction and all others data.
Colistina sulphate is a cyclopeptide antibiotic belongs to the polymixin therapeutic class and identical to polymixin E. Colistina is used for the prevention and treatment of diseases caused by sensitive bacteria in poultry and large animal. It causes disorganization of bacterial cell membrane with leakage of intracellular materials and thus inhibits bacterial oxidative metabolism. Resistance to colistin is uncommon.
Colistina is a polymyxin antibiotic agent. Polymyxins are cationic polypeptides that disrupt the bacterial cell membrane through a detergentlike mechanism. With the development of less toxic agents, such as extended-spectrum penicillins and cephalosporins, parenteral polymyxin use was largely abandoned, except for the treatment of multidrug-resistant pulmonary infections in patients with cystic fibrosis. More recently, however, the emergence of multidrug-resistant gram-negative bacteria, such as Pseudomonas aeruginosa and Acinetobacter baumannii, and the lack of new antimicrobial agents have led to the revived use of the polymyxins.

How Colistina works
Colistina is a surface active agent which penetrates into and disrupts the bacterial cell membrane. Colistina is polycationic and has both hydrophobic and lipophilic moieties. It interacts with the bacterial cytoplasmic membrane, changing its permeability. This effect is bactericidal. There is also evidence that polymyxins enter the cell and precipitate cytoplasmic components, primarily ribosomes.
Dosage
Colistina dosage
Broiler, Shonali, Layer and Breeder: 1ml/2-4 liter water for 3-5 days.Cattle, Calf, Goat and sheep: 1ml/40 kg body weight twice daily for 3-5 days.Or as Directed by the registered Veterinarian.
Toxicity
Oral LD50 in rats is 5450 mg/kg. Overdosage with colistimethate can cause neuromuscular blockade characterized by paresthesia, lethargy, confusion, dizziness, ataxia, nystagmus, disorders of speech and apnea. Respiratory muscle paralysis may lead to apnea, respiratory arrest and death.
