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

Cefixime is a semi-synthetic, broad spectrum cephalosporin antibiotic of third generation for oral administration. It is a bactericidal antibiotic, kills bacteria by interfering in the synthesis of the bacterial cell wall. Cefixime is highly stable in the presence of beta-lactamase enzymes. Cefixime has marked in -vitro bactericidal activity against a wide variety of Gram-positive and Gram-negative organisms including beta lactamase producers.

Clinical efficacy of Cefixime has been demonstrated in infections caused by commonly occurring pathogens including Gram-positive organism Streptococcus pneumoniae, Streptococcus pyogenes, Gram-negative organism Escherichia coli, Proteus mirabilis, Klebsiella spp., Haemophilus influenzae (beta-lactamase positive and negative), Moraxella catarrhalis (beta-lactamase positive and negative), Salmonella typhi and Enterobacter species.

Cefixime, an antibiotic, is a third-generation cephalosporin like ceftriaxone and cefotaxime. Cefixime is highly stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillins and some cephalosporins due to the presence of beta-lactamases, may be susceptible to cefixime. The antibacterial effect of cefixime results from inhibition of mucopeptide synthesis in the bacterial cell wall.

Dicloxacillin inhibits bacterial cell wall synthesis by binding to 1 or more of the penicillin-binding proteins (PBPs) which in turn inhibit the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

Dicloxacillin is a beta-lactamase resistant penicillin similar to oxacillin. Dicloxacillin has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. The bactericidal activity of dicloxacillin results from the inhibition of cell wall synthesis and is mediated through dicloxacillin binding to penicillin binding proteins (PBPs). Dicloxacillin is stable against hydrolysis by a variety of beta-lactamases, including penicillinases, and cephalosporinases and extended spectrum beta-lactamases.

How Belfix Dc works

Like all beta-lactam antibiotics, cefixime 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; it is possible that cefixime interferes with an autolysin inhibitor.

Dicloxacillin exerts a bactericidal action against penicillin-susceptible microorganisms during the state of active multiplication. All penicillins inhibit the biosynthesis of the bacterial cell wall. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, dicloxacillin inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that dicloxacillin interferes with an autolysin inhibitor.

Dosage

Belfix Dc dosage

The usual treatment of Cefixime is 7 days. This may be continued for up to 14 days according to the severity of infection.

Cefixime Capsule

Adult and child over 12 years: 200 or 400 mg daily as a single dose or in two divided doses.

Cefixime Suspension

Child over 6 months: 8 mg/kg daily as a single dose or in 2 divided doses

Adult: 125-250 mg 6 hourly. Doses may be doubled in severe infections.

Child: <40 kg: 12.5-25 mg/kg 6 hourly.

Should be taken on an empty stomach. Take at least 1 hr before or 2 hr after meals.

Direction for Reconstitution of Suspension

• To prepare 50 ml suspension, 25 ml boiled and cooled water is required.

• To prepare 40 ml suspension, 20 ml boiled and cooled water is required.

• To prepare 30 ml suspension, 15 ml boiled and cooled water is required.

• To prepare 50 ml DS suspension, 25 ml boiled and cooled water is required.

Tap the bottle several times to loosen powder contents prior to reconstitution. Add approximately half of the total amount of water and shake well. Add remainder of water, and then shake again.

Note: Shake the suspension well before each use. Keep the bottle tightly closed. The reconstituted suspension should be stored in a cool and dry place, preferably in refrigerator and unused portion should be discarded after 14 days.

Side Effects

Cefixime is generally well tolerated. The majority of adverse reactions observed in clinical trials are mild and self limiting in nature.

Gastro-intestinal disturbance: Diarrhea (if severe diarrhea occurs, Cefixime should be discontinued), changes in the color of stool, nausea, abdominal pain, dyspepsia, vomiting, flatulence have been reported. CNS disturbances: Headache, dizziness.

Others: Hypersensitivity reactions which usually subsided upon discontinuation of therapy; infrequent and reversible hematological changes; elevation of serum amylase.

Hypersensitivity reactions (e.g. urticaria, fever, joint pains, rashes, angioedema, serum sickness-like reactions), nausea, vomiting, diarrhoea, stomatitis, black/hairy tongue, neurotoxic reactions, renal tubular damage, interstitial nephritis, eosinophilia, haemolytic anaemia, agranulocytosis, neutropenia, leucopenia, granulocytopenia, bone marrow depression, hepatotoxicity, cholestatic hepatitis.

Toxicity

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

Oral LD₅₀ in rat is 3579 mg/kg. Symptoms of overexposure include irritation, rash, labored breathing, hives, itching, wheezing, nausea, chills, and fever.

Precaution

Cefixime should be prescribed with caution in individuals with a history of gastrointestinal diseases, particularly colitis. Dosage adjustment is only necessary in severe renal failure (creatinine clearance < 20 ml/min)

Patient with history of allergy esp β-lactam allergy, asthma. Pregnancy and lactation.

Interaction

Increased prothrombin time (with or withot bleeding) with anticoagulants (e.g. warfarin). Increased plasma carbamazepine concentrations with concomitant use. Increased bioavailability with nifedipine. Increased serum concentration with probenecid.

Probenecid prolongs serum levels of dicloxacillin. Bacteriostatic drugs (e.g. chloramphenicol, tetracyclines) may antagonise the bactericidal effect of dicloxacillin. May reduce anticoagulant response to dicumarol and warfarin. May increase risk of methotrexate toxicity. May diminish the effect of live vaccines (e.g. typhoid vaccine).

Elimination Route

About 40%-50% absorbed orally whether administered with or without food, however, time to maximal absorption is increased approximately 0.8 hours when administered with food.

Absorption of the isoxazolyl penicillins after oral administration is rapid but incomplete: peak blood levels are achieved in 1-1.5 hours. Oral absorption of cloxacillin, dicloxacillin, oxacillin and nafcillin is delayed when the drugs are administered after meals.

Half Life

3-4 hours (may range up to 9 hours). In severe renal impairment (5 to 20 mL/min creatinine clearance), the half-life increased to an average of 11.5 hours.

The elimination half-life for dicloxacillin is about 0.7 hour.

Elimination Route

Dicloxacillin sodium is rapidly excreted as unchanged drug in the urine by glomerular filtration and active tubular secretion.

Pregnancy & Breastfeeding use

Pregnancy: Pregnancy category B. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

Lactation: It is not known whether Cefixime is excreted in human milk. Consideration should be given to discontinuing nursing temporarily during treatment with this drug.

Use in Elderly

No special precautions are necessary. No dosage adjustment is required for elderly

Pregnancy Category B. Either animal-reproduction studies have not demonstrated a fetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters).

Contraindication

Patients with known hypersensitivity to cephalosporin antibiotics, children under 6 months.

Hypersensitivity to dicloxacillin and other penicillins.

Special Warning

Use in Children: Safety and effectiveness of cefixime in children aged less than 6 months have not been established. For children younger than 12 years or weighing less than 50 kg, the usual dose is 8 mg/kg/day.

Use in elderly: No special precautions are necessary. Old age is not an indication for dose adjustment.

Dosage in renal impairment:

Creatinine clearance: 20 ml/min or greater: normal dose
Creatinine clearance: <20 ml/min or chronic ambulatory peritoneal dialysis
Haemodialysis: daily dose should not exceed 200 mg.

Acute Overdose

Gastric lavage may be indicated; otherwise, no specific antidote exists. Cefixime is not removed in significant quantities from the circulation by hemodialysis or peritoneal dialysis. Adverse reactions in small numbers of healthy adult volunteers receiving single doses up to 2 g of Cefixime did not differ from the profile seen in patients treated at the recommended doses.
