Pirazone

Pirazone Uses, Dosage, Side Effects, Food Interaction and all others data.

Like all beta-lactam antibiotics, cefoperazone binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, causing the inhibition of the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins.

Pirazone is a third generation cephalosporin antibiotic. Pirazone exerts its bactericidal effect by inhibiting the bacterial cell wall synthesis

Uses

Pirazone is used for the treatment of the following infections when caused by susceptible organisms: Respiratory Tract Infections, Peritonitis & Other Intra-abdominal Infections, Bacterial Septicemia, Skin and Skin Structures Infections, Pelvic Inflammatory Disease, Endometritis & Other Infections of the Female Genital Tract, Urinary Tract Infections, Enterococcal Infections etc.

Pirazone is also used to associated treatment for these conditions: Bacterial Infections, Bloodstream Infections, Bone and Joint Infections, Intra-Abdominal Infections, Lower Respiratory Tract Infection (LRTI), Meningitis, Peritonitis, Postoperative Infections, Skin and Soft Tissue Infections, Upper Respiratory Tract Infection, Urinary Tract Infection, Genital tract infection

How Pirazone works

Like all beta-lactam antibiotics, cefoperazone binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, causing the inhibition of the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins.

Dosage

Pirazone dosage

Sterile Pirazone Sodium can be administered by IM or IV injection (following dilution).

Adult: 2 to 4 grams per day administered in equally divided doses every 12 hours. In severe infections or infections caused by less sensitive organisms, the total daily dose and/or frequency may be increased. Patients have been successfully treated with a total daily dosage of 6-12 grams divided into 2,3, or 4 administrations ranging from 1.5 to 4 grams per dose. When treating infections caused by Streptococcus pyogenes, therapy should be continued for at least 10 days

Pirazone for intravenous or intramuscular use may be initially reconstituted with compatible solution. Solutions should be allowed to stand after reconstitution to allow any foaming to dissipate to permit visual inspection for complete solubilization. Vigorous and prolonged agitation may be necessary to solubilize Pirazone in higher concentrations (above 333 mg Pirazone/ml). The maximum solubility of Pirazone is approximately 475 mg Pirazone/ml of compatible diluent.

Side Effects

As with all Cephalosporins, hypersensitivity manifested by skin reactions (1 patient in 45), drug fever (1 in 260), or a change in Coombs' test (1 in 60) has been reported. These reactions are more likely to occur in patients with a history of allergies, particularly to Penicillin.

Toxicity

Symptoms of overdose include blood in the urine, diarrhea, nausea, upper abdominal pain, and vomiting.

Precaution

Pirazone is extensively excreted in bile. The serum half-life of Pirazone is increased 2-4 fold in patients with hepatic disease and/or biliary obstruction. In general, total daily dosage above 4 gm should not be necessary in such patients. If higher dosages are used, serum concentrations should be monitored.

Food Interaction

  • Avoid alcohol. Ingesting alcohol with cefoperazone may precipitate a disulfuram like reaction including symptoms such as flushing, tachycardia, sweating, and headache.

Pirazone Alcohol interaction

[Moderate] GENERALLY AVOID:

Some cephalosporins may occasionally induce a disulfiram-like reaction when coadministered with alcohol.

The interaction has been reported for cefamandole, cefoperazone, cefotetan, and moxalactam.

These agents contain an N-methylthiotetrazole (NMTT) side chain that may inhibit aldehyde dehydrogenase (ALDH) similar to disulfiram.

Following ingestion of alcohol, inhibition of ALDH results in increased concentration of acetaldehyde, the accumulation of which produces an unpleasant physiologic response referred to as the 'disulfiram reaction'.

Symptoms include flushing, throbbing in head and neck, throbbing headache, respiratory difficulty, nausea, vomiting, sweating, thirst, chest pain, palpitation, dyspnea, hyperventilation, tachycardia, hypotension, syncope, weakness, vertigo, blurred vision, and confusion.

Severe reactions may result in respiratory depression, cardiovascular collapse, arrhythmias, myocardial infarction, acute congestive heart failure, unconsciousness, convulsions, and death.

Cefonicid contains a structurally similar side chain but did not produce elevations in blood acetaldehyde or a disulfiram reaction to ethanol in 15 healthy volunteers given single and multiple one gram doses of the drug.

Patients receiving cephalosporins with the NMTT side chain should avoid the concomitant use of alcohol and alcohol-containing products.

Pirazone Hypertension interaction

[Moderate] Parenteral cefoperazone sodium contains approximately 34 mg (1.5 mEq) of sodium per each gram of cefoperazone activity.

The sodium content should be considered in patients with conditions that may require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.

Half Life

The mean serum half-life is approximately 2.0 hours, independent of the route of administration.

Elimination Route

Pirazone is excreted mainly in the bile.

Pregnancy & Breastfeeding use

Pregnancy Category B.This drug should be used during pregnancy only if clearly needed. Only low concentrations of Pirazone is excreted in human milk. Although Pirazone passes poorly into breast milk of nursing mothers, caution should be exercised when Pirazone is administered to a nursing woman.

Contraindication

Pirazone is contraindicated in patients with known allergy to the Cephalosporin-class of antibiotics.

Special Warning

Children use: Safety and effectiveness in children have not been established.

Geriatric use: Reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Storage Condition

Pirazone is to be stored in a dry place, below 25°C and protected from light prior to reconstitution. The reconstituted solution may be stored for 24 hours if kept in room temperature (below 25°C).

FAQ

What is Pirazone used for?

Pirazone is a cephalosporin antibiotic used to treat infections caused by bacteria.

How safe is Pirazone?

The clinical efficacy and safety of Pirazone-sulbactam were similar to those of alternative antibiotics in the treatment of intra-abdominal infections. Therefore, Pirazone -sulbactam could be recommended as an effective and safe antibiotic for treating intra-abdominal infections.

How does Pirazone work?

Pirazone works by killing bacteria or preventing their growth. Pirazone exerts its bactericidal effect by inhibiting the bacterial cell wall synthesis, and sulbactam acts as a beta-lactamase inhibitor, to increase the antibacterial activity of Pirazone bagainst beta-lactamase-producing organisms.

What are the common side effects of Pirazone?

Common side effects of Pirazone include:

  • diarrhea,
