Dosage of Amrizol in details
The 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.
In elderly patients the pharmacokinetics of Amrizol may be altered and therefore monitoring of serum levels may be necessary to adjust the Amrizol dosage accordingly.
Treatment of Anaerobic Infections
The recommended dosage schedule for adults is:
Parenteral therapy may be changed to oral Amrizol when conditions warrant, based upon the severity of the disease and the response of the patient to Amrizol Injection, USP RTU treatment. The usual adult oral dosage is 7.5 mg/kg every six hours.
A maximum of 4 g should not be exceeded during a 24-hour period.
Patients with severe hepatic disease metabolize Amrizol slowly, with resultant accumulation of Amrizol and its metabolites in the plasma. Accordingly, for such patients, doses below those usually recommended should be administered cautiously. Close monitoring of plasma Amrizol levels and toxicity is recommended.
In patients receiving Amrizol Injection, USP RTU in whom gastric secretions are continuously removed by nasogastric aspiration, sufficient Amrizol may be removed in the aspirate to cause a reduction in serum levels.
The dose of Amrizol Injection, USP RTU should not be specifically reduced in anuric patients since accumulated metabolites may be rapidly removed by dialysis.
The usual duration of therapy is 7 to 10 days; however, infections of the bone and joint, lower respiratory tract and endocardium may require longer treatment.
For surgical prophylactic use, to prevent postoperative infection in contaminated or potentially contaminated colorectal surgery, the recommended dosage schedule for adults is:
It is important that (1) administration of the initial preoperative dose be completed approximately one hour before surgery so that adequate drug levels are present in the serum and tissues at the time of initial incision, and (2) Amrizol Injection, USP RTU be administered, if necessary, at 6-hour intervals to maintain effective drug levels. Prophylactic use of Amrizol Injection, USP RTU should be limited to the day of surgery only, following the above guidelines.
Caution: Amrizol Injection, USP RTU is to be administered by slow intravenous drip infusion only, either as a continuous or intermittent infusion. Additives should not be introduced into Amrizol Injection, USP RTU. If used with a primary intravenous fluid system, the primary solution should be discontinued during Amrizol infusion. DO NOT USE EQUIPMENT CONTAINING ALUMINUM (e.g., NEEDLES, CANNULAE) THAT WOULD COME IN CONTACT WITH THE DRUG SOLUTION.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
Amrizol Injection, USP RTU is supplied in 100 mL single dose plastic containers, each containing an iso-osmotic, buffered solution of 500 mg Amrizol as follows:
2B3421 -NDC 0338-1055-48 -500 mg/100 mL
Store at controlled room temperature, 59° to 86°F (15° to 30°C) and protect from light during storage. Do not remove unit from overwrap until ready for use. The overwrap is a moisture barrier. The inner bag maintains the sterility of the product. After removing overwrap, check for minute leaks by squeezing inner bag firmly. If leaks are found, discard solution as sterility may be impaired.
Directions For Use Of Viaflex Plus Plastic Container
Amrizol Injection, USP RTU is a ready-to-use iso-osmotic solution. No dilution or buffering is required. Do not refrigerate. Each container of Amrizol Injection, USP RTU contains 14 mEq of sodium.
Warning: Do not use plastic containers in series connections. Such use could result in air embolism due to residual air being drawn from the primary container before administration of the fluid from the secondary container is completed.
Tear overwrap down side at slit and remove solution container. Some opacity of the plastic due to moisture absorption during the sterilization process may be observed. This is normal and does not affect the solution quality or safety. The opacity will diminish gradually. Check for leaks. Do not add supplementary medication.

What other drugs will affect Amrizol?
Tell your doctor about all other medicines you use, especially:
This list is not complete and other drugs may interact with Amrizol. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
Interactions 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 Amrizol, 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.
Psychotic reactions have been reported in alcoholic patients who are using Amrizol and disulfiram concurrently. Amrizol should not be given to patients who have taken disulfiram within the last two weeks.
Abdominal cramps, nausea, vomiting, headaches, and flushing may occur if alcoholic beverages or products containing propylene glycol are consumed during or following Amrizol therapy.
Warfarin And Other
Amrizol has been reported to potentiate the anticoagulant effect of warfarin and other oral coumarin anticoagulants, resulting in a prolongation of prothrombin time. When Amrizol is prescribed for patients on this type of anticoagulant therapy, prothrombin time and INR should be carefully monitored.
In patients stabilized on relatively high doses of lithium, short-term Amrizol therapy has been associated with elevation of serum lithium and, in a few cases, signs of lithium toxicity. Serum lithium and serum creatinine levels should be obtained several days after beginning Amrizol to detect any increase that may precede clinical symptoms of lithium intoxication.
Amrizol has been reported to increase plasma concentrations of busulfan, which can result in an increased risk for serious busulfan toxicity. Amrizol should not be administered concomitantly with busulfan unless the benefit outweighs the risk. If no therapeutic alternatives to Amrizol are available, and concomitant administration with busulfan is medically needed, frequent monitoring of busulfan plasma concentration should be performed and the busulfan dose should be adjusted accordingly.
Drugs That Inhibit CYP450 Enzymes
The simultaneous administration of drugs that decrease microsomal liver enzyme activity, such as cimetidine, may prolong the half-life and decrease plasma clearance of Amrizol.
Drugs That Induce CYP450 Enzymes
The simultaneous administration of drugs that induce microsomal liver enzymes, such as phenytoin or phenobarbital, may accelerate the elimination of Amrizol, resulting in reduced plasma levels; impaired clearance of phenytoin has also been reported.
Drug/Laboratory Test Interactions
Amrizol may interfere with certain types of determinations of serum chemistry values, such as aspartate aminotransferase (AST, SGOT), alanine aminotransferase (ALT, SGPT), lactate dehydrogenase (LDH), triglycerides, and glucose hexokinase. Values of zero may be observed. All of the assays in which interference has been reported involve enzymatic coupling of the assay to oxidation-reduction of nicotinamide adenine dinucleotide (NAD- NADH). Interference is due to the similarity in absorbance peaks of NADH (340 nm) and Amrizol (322 nm) at pH 7.

2 consumers reported dosesWhat doses of Amrizol 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 Amrizol 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.
