Neutim

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

Neutim is a semisynthetic, broad-spectrum, beta-lactam antibiotic for parenteral administration. Neutim is bactericidal in action exerting its effect by inhibition of enzymes responsible for cell-wall synthesis. A wide range of gram-negative organisms is susceptible to ceftazidime in vitro, including strains resistant to gentamicin and other aminoglycosides. In addition, ceftazidime has been shown to be active against gram-positive organisms. It is highly stable to most clinically important beta-lactamases, plasmid or chromosomal, which are produced by both gram-negative and gram-positive organisms and, consequently, is active against many strains resistant to ampicillin and other cephalosporins.

Neutim is a semisynthetic, broad-spectrum, third-generation cephalosporin antibiotic that is bactericidal through inhibition of enzymes responsible for cell-wall synthesis, primarily penicillin-binding protein 3 (PBP3). Among cephalosporins, ceftazidime is notable for its resistance to numerous β-lactamases and its broad spectrum of activity against Gram-negative bacteria, including Pseudomonas aeruginosa. However, it is less active than first- and second-generation cephalosporins against Staphylococcus aureus and other Gram-positive bacteria and also has low activity against anaerobes. Neutim has confirmed activity against clinically relevant Gram-negative bacteria including Citrobacter spp., Enterobacter spp., Klebsiella spp., Proteus spp., Serratia spp., _Escherichia coli, Haemophilus influenzae, Neisseria meningitidis, Pseudomonas aeruginosa, and some Gram-positive bacteria including Staphylococcus spp. and Streptococcus spp. There are also in vitro data for ceftazidime efficacy against a wide variety of other bacteria, such as Acinetobacter baumannii and Neisseria gonorrhoeae, but no clear clinical studies to support the use of ceftazidime for infections caused by these bacteria.

Although β-lactam antibiotics like ceftazidime are generally well tolerated, there remains a risk of serious acute hypersensitivity reactions, which is higher in patients with a known allergy to ceftazidime or any other β-lactam antibiotic. As with all antibiotics, ceftazidime may result in the overgrowth of non-susceptible organisms and potentially serious effects including Clostridium difficile-associated diarrhea (CDAD); CDAD should be considered in patients who develop diarrhea and, in confirmed cases, supportive care initiated immediately. Neutim is primarily renally excreted such that high and prolonged serum concentrations can occur in patients with renal insufficiency, leading to seizures, nonconvulsive status epilepticus (NCSE), encephalopathy, coma, asterixis, neuromuscular excitability, and myoclonia. Treatment may lead to the development or induction of resistance with a risk of treatment failure. Periodic susceptibility testing should be considered, and monotherapy failure may necessitate the addition of another antibiotic such as an aminoglycoside. Cephalosporin use may decrease prothrombin activity, which may be improved by exogenous vitamin K. Inadvertent intra-arterial administration of ceftazidime may result in distal necrosis.

How Neutim works

The bacterial cell wall, which is located at the periphery of Gram-positive bacteria and within the periplasm of Gram-negative bacteria, comprises a glycopeptide polymer synthesized through cross-linking of glycans to peptide stems on alternating saccharides, which is known commonly as peptidoglycan. Cell wall formation, recycling, and remodelling require numerous enzymes, including a family of enzymes with similar active site character despite distinct and sometimes overlapping roles as carboxypeptidases, endopeptidases, transpeptidases, and transglycosylases, known as "penicillin-binding proteins" (PBPs). The number of PBPs differs between bacteria, in which some are considered essential and others redundant. In general, inhibition of one or more essential PBPs results in impaired cell wall homeostasis, loss of cell integrity, and is ultimately bactericidal.

Neutim is a semisynthetic third-generation cephalosporin with broad activity against numerous Gram-negative and some Gram-positive bacteria. Like other β-lactam antibiotics, ceftazidime exhibits its bactericidal effect primarily through direct inhibition of specific PBPs in susceptible bacteria. In vitro experiments in Gram-negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae suggest that ceftazidime primarily binds to PBP3, with weaker binding to PBP1a/1b and PBP2 as well; although binding to other PBPs, such as PBP4, is detectable, the concentrations required are much greater than those achieved clinically. Similarly, ceftazidime showed binding to Staphylococcus aureus PBP 1, 2, and 3 with a much lower affinity for PBP4. Recent data for Mycobacterium abcessus suggest that ceftazidime can inhibit PonA1, PonA2, and PbpA at intermediate concentrations.

Step 2: Gently shake the vial to dissolve the powder. Carbon dioxide is released & a clear solution will be obtained.

Step 3: Now insert the needle in the free space of the reconstituted vial & withdraw the pressurized air from the free space.

Step 4: Finally withdraw the solution from the vial by syringe

Side Effects

The most common side-effects are local reactions following IV injection and allergic and gastrointestinal reactions. Hypersensitivity reactions are pruritus, rash, and fever. Angioedema and anaphylaxis have been reported very rarely. Gastrointestinal symptoms are diarrhea, nausea, vomiting, and abdominal pain. Central nervous system reactions included headache, dizziness, and paresthesia.

Toxicity

Neutim overdosage has occurred in patients with renal failure. Reactions included seizure activity, encephalopathy, asterixis, neuromuscular excitability, and coma. Patients who receive an acute overdosage should be carefully observed and given supportive treatment. In the presence of renal insufficiency, hemodialysis or peritoneal dialysis may aid in the removal of ceftazidime from the body.

Precaution

The total daily dosage should be reduced when Neutim is administered to patients with renal insufficiency. Ceftazidine should be prescribed with caution in individuals with a history of gastrointestinal disease, particularly colitis.

Interaction

Increased nephrotoxicity has been reported following concomitant administration of Cephalosporins and aminoglycoside antibiotics.

Food Interaction

No interactions found.

Neutim Hypertension interaction

[Moderate] Fortaz, Tazicef, and Tazidime (brands of parenteral ceftazidime pentahydrate) are formulated with sodium carbonate and contain approximately 53 mg (2.3 mEq) of sodium per each gram of ceftazidime 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.

Ceptaz, another brand of ceftazidime, is formulated with l-arginine and contains no sodium.

Volume of Distribution

Neutim has a volume of distribution of 15-20 L.

Elimination Route

Neutim administered intravenously in healthy males produced mean Cmax values of between 42 and 170 μg/mL for doses between 500 mg and 2 g, and are reached immediately following the end of the infusion period. The Cmax for 1 g of ceftazidime administered intramuscularly is attained approximately one hour following injection and is between 37 and 43 mg/L. Following intramuscular administration of 500 mg and 1 g of ceftazidime, the serum concentration remained above 4 μg/mL for six and eight hours, respectively.

Neutim Cmax and AUC show linear proportionality to the dose over the therapeutic range. In individuals with normal renal function, ceftazidime given intravenously every eight hours for 10 days as either 1 or 2 g doses showed no accumulation.

Half Life

Neutim has an elimination half-life of 1.5-2.8 hours in healthy subjects. As ceftazidime is primarily renally excreted, its half-life is significantly prolonged in patients with renal impairment. In patients with creatinine clearance < 12 mL/min, the half-life is prolonged to between 14 and 30 hours.

Clearance

The mean renal clearance of ceftazidime in healthy subjects ranges from 72 to 141 mL/min while the calculated plasma clearance is approximately 115 mL/min.

Elimination Route

Approximately 80% to 90% of an intramuscular or intravenous dose of ceftazidime is excreted unchanged by the kidneys over a 24-hour period. When administered intravenously, 50% of the dose appears in the urine within two hours, with another 32% of the dose appearing by eight hours post-administration.

Pregnancy & Breastfeeding use

Pregnancy: No adequate and well controlled studies in pregnant women have been conducted with Neutim. Because animal reproduction studies are not always predictive of human response this drug should be used during pregnancy only if clearly needed.

Lactation: Neutim is excreted in human milk in low concentrations. Because many drugs are excreted in human milk and because safety of the component of the injections in nursing infants has not been established, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Contraindication

Neutim is contraindicated in patients with known hypersensitivity to cephalosporin antibiotics.

Acute Overdose

Neutim overdosage has occurred in patients with renal failure. Reactions have included seizure activity, encephalopathy, asterixis, neuromuscular excitability, and coma. Patients who receive an acute overdosage should be carefully observed and given supportive treatment.

Storage Condition

Store below 25° C, protected from light and moisture. Reconstituted solutions are stable for up to 24 h if stored between 2°-8° C
