Dosage of Chloramphenicol in details

infoThe dose of a drug and dosage of the drug are two different terminologies. Dose is defined as the quantity or amount of medicine given by the doctor or taken by the patient at a given period. Dosage is the regimen prescribed by the doctor about how many days and how many times per day the drug is to be taken in specified dose by the patient. The dose is expressed in mg for tablets or gm, micro gm sometimes, ml for syrups or drops for kids syrups. The dose is not fixed for a drug for all conditions, and it changes according to the condition or a disease. It also changes on the age of the patient.

Chloramphenicol, like other potent drugs, should be prescribed at recommended doses known to have therapeutic activity. Administration of 50 mg/kg/day in divided doses will produce blood levels of the magnitude to which the majority of susceptible microorganisms will respond.

As soon as feasible an oral dosage form of another appropriate antibiotic should be substituted for intravenous Chloramphenicol sodium succinate.

The following method of administration is recommended:

Intravenously as a 10% (100 mg/mL) solution to be injected over at least a one-minute interval. This is prepared by the addition of 10 mL of an aqueous diluent such as water for injection or 5% dextrose injection.

Adults

Adults should receive 50 mg/kg/day in divided doses at 6-hour intervals. In exceptional cases patients with infections due to moderately resistant organisms may require increased dosage up to 100 mg/kg/day to achieve blood levels inhibiting the pathogen, but these high doses should be decreased as soon as possible. Adults with impairment of hepatic or renal function or both may have reduced ability to metabolize and excrete the drug. In instances of impaired metabolic processes, dosages should be adjusted accordingly. Precise control of concentration of the drug in the blood should be carefully followed in patients with impaired metabolic processes by the available microtechniques (information available on request).

Pediatric Patients

Dosage of 50 mg/kg/day divided into 4 doses at 6-hour intervals yields blood levels in the range effective against most susceptible organisms. Severe infections (eg, bacteremia or meningitis), especially when adequate cerebrospinal fluid concentrations are desired, may require dosage up to 100 mg/kg/day; however, it is recommended that dosage be reduced to 50 mg/kg/day as soon as possible. Children with impaired liver or kidney function may retain excessive amounts of the drug.

Neonates

A total of 25 mg/kg/day in 4 equal doses at 6-hour intervals usually produces and maintains concentrations in blood and tissues adequate to control most infections for which the drug is indicated. Increased dosage in these individuals, demanded by severe infections, should be given only to maintain the blood concentration within a therapeutically effective range. After the first two weeks of life, full-term neonates ordinarily may receive up to a total of 50 mg/kg/day equally divided into 4 doses at 6-hour intervals. These dosage recommendations are extremely important because blood concentration in all premature and full-term neonates under two weeks of age differs from that of other infants neonates. This difference is due to variations in the maturity of the metabolic functions of the liver and the kidneys.

When these functions are immature (or seriously impaired in adults), high concentrations of the drug are found which tend to increase with succeeding doses.

Pediatric Patients with Immature Metabolic Processes

In young infants and other pediatric patients in whom immature metabolic functions are suspected, a dose of 25 mg/kg/day will usually produce therapeutic concentrations of the drug in the blood. In this group particularly, the concentration of the drug in the blood should be carefully followed by microtechniques. (Information available on request.)

Chloramphenicol interactions

infoInteractions are the effects that happen when the drug is taken along with the food or when taken with other medications. Suppose if you are taking a drug Chloramphenicol, it may have interactions with specific foods and specific medications. It will not interact with all foods and medications. The interactions vary from drug to drug. You need to be aware of interactions of the medicine you take. Most medications may interact with alcohol, tobacco, so be cautious.

There are no known drug interactions arising from the use of topical medication. Vitamin E administered systemically can increase the pharmacological action of insulin and digital. The absorption and accumulation of vitamin A can be reduced respectively by Neomycin sulphate some drugs such corticosteroids administered for prolonged periods, phenobarbital, caffeine and alcohol. And ’demonstrated a significant relationship between vitamin D and phenytoin or phenobarbital.

Among patients treated with these drugs for a long time, it is noted a high incidence of rickets and osteomalacia. Chloramphenicol irreversibly inhibits the enzymes of hepatic microsomal cytochrome P450 complex and this may result in a longer half-lives of drugs metabolized by this system (dicoumarol, phenytoin, chlorpropamide and tolbutamide). Chronic administration of phenobarbital or acute administration of rifampicin shorten the half-lives of Chloramphenicol and subsequent formation of sub-therapeutic concentrations of the drug.

What doses of Chloramphenicol drug you have used?
The drug can be in various doses. Most anti-diabetic, anti-hypertensive drugs, pain killers, or antibiotics are in different low and high doses and prescribed by the doctors depending on the severity and demand of the condition suffered by the patient. In our reports, ndrugs.com website users used these doses of Chloramphenicol drug in following percentages. Very few drugs come in a fixed dose or a single dose. Common conditions, like fever, have almost the same doses, e.g., [acetaminophen, 500mg] of drug used by the patient, even though it is available in various doses.
