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

Cefpodoxime Proxetil is an orally administered extended spectrum, semi-synthetic 3rd generation antibiotic of cephalosporin class. Like other β-lactam antibiotics it is a bactericidal drug that acts by inhibition of bacterial cell wall synthesis.

Cefpodoxime is shown to be effective against most Gram positive and Gram negative bacteria, except Pseudomonas aeruginosa, Enterococcus, and Bacteroides fragilis.

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.

Uses

Cefpodoxime is used for the treatment of patients infected with susceptible strains of micro-organisms which include a wide range of gram-positive & gram-negative bacteria. As it is highly stable in presence of b-lactamase enzyme, so it is more effective against gram-positive bacteria than other 3rd generation oral Cephalosporins.

The susceptible organisms include gram-positive bacteria eg. S. aureus (including penicillinase producing strains), S. saprophyticus, S. pneumoniae, S. pyogenes, S. agalactiae, P. magnus and gram-negative bacteria eg. E. coli, K. pneumoniae, H. influenzae (including b-lactamase producer & Ampicillin resistant strains), M. catarrhalis, N. gonorrhoeae (including penicillinase producing strains), P. mirabillis, C. diversus, H. parainfluenzae, K. oxytoca, P. vulgaris, P. rettgeri.

Ximeprox is used for the following diseases:-

(1) Lower respiratory tract infection: Acute community-acquired pneumonia, Acute bacterial exacerbation of chronic bronchitis; (2) Upper respiratory tract infection: Acute otitis media, Acute maxillary sinusitis, Pharyngitis, Tonsillitis; (3) Sexually transmitted diseases: Acute uncomplicated urethral & cervical gonorrhea, Acute ano-rectal infection in woman caused by N. gonorrhoeae; (4) Uncomplicated urinary tract infection: Cystitis, Pyuria; (5) Skin & soft tissue infections: Furuncle, Cellulitis, Subcutaneous abscess, infectious atheroma & periproctal abscess (6) Enteric fever.

How Asdox D works

Cefpodoxime is active against a wide spectrum of Gram-positive and Gram-negative bacteria. Cefpodoxime is stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillins and cephalosporins, due to their production of beta-lactamase, may be susceptible to cefpodoxime. Cefpodoxime is inactivated by certain extended spectrum beta-lactamases. The bactericidal activity of cefpodoxime results from its inhibition of cell wall synthesis. The active metabolite of cefpodoxime binds preferentially to penicillin binding protein 3, which inhibits production of peptidoglycan, the primary constituent of bacterial cell walls.

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

Asdox D dosage

Ximeprox should be administered orally with food to enhance absorption. Ximeprox suspension may be given without regard to food.

15 days - 6 months : 4 mg/kg every 12 hours

6 months - 2 years : 40 mg every 12 hours

3 - 8 years : 80 mg every 12 hours

over 9 years : 100 mg every 12 hours

Patients with renal dysfunction: For patients with severe renal impairment (creatinine clearance <30 ml/min) the dosing intervals should be increased to 24 hourly.

Patients with liver cirrhosis: Cefpodoxime proxetil pharmacokinetics in cirrhotic patients are similar to those in healthy subjects. Dose adjustment is not necessary in this population.

For 50 ml DS suspension : Add 25 ml (5 measuring spoonful) of boiled and cooled water to the dry mixture in the bottle. For ease of preparation add water to the bottle in two portions. Shake well after each addition until all the powder is in suspension.

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 10 days.

Side Effects

Cefpodoxime has very few side effects. The side effects include diarrhea, nausea, skin & vaginal fungal infection, abdominal pain, headache, chest pain, myalgia, dyspepsia, dizziness, vertigo, cough etc. In children incidence of fungal skin rash is more than adults.

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

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

Precaution

In patients with transient or persistent reduction in urinary output due to renal insufficiency, the total daily dose of cefpodoxime proxetil should be reduced. Cefpodoxime, like other cephalosporins, should be administered with caution to patients receiving concurrent treatment with potent diuretics. As with other broad spectrum antibiotics, prolonged use of cefpodoxime proxetil may result in overgrowth of non-susceptible organisms. Repeated evaluation of the patient's condition is essential.

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

Interaction

Antacids or H2-blockers may decrease the absorption of cefpodoxime. Reduced renal excretion 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

Cefpodoxime proxetil is a prodrug that is absorbed from the gastrointestinal tract and de-esterified to its active metabolite, cefpodoxime. Following oral administration of 100 mg of cefpodoxime proxetil to fasting subjects, approximately 50% of the administered cefpodoxime dose was absorbed systemically.

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

2.09 to 2.84 hours

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

Elimination Route

Over the recommended dosing range (100 to 400 mg), approximately 29 to 33% of the administered cefpodoxime dose was excreted unchanged in the urine in 12 hours.

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

Pregnancy & Breastfeeding use

There are no adequate and well-controlled studies on Cefpodoxime proxetil use in pregnant woman, but it was found neither teratogenic nor embryocidal in animal trial. However, the drug should be used during pregnancy only if clearly needed. In nursing mother, Cefpodoxime is excreted in breast milk & there is potential risk of serious reactions in nursing infants, so a decision should be made whether to discontinue breast feeding or to discontinue the drug.

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

Cefpodoxime is contraindicated in patients with known allergy to the cephalosporin class of antibiotics.

Renal Impairment: Patients with renal dysfunction: For patients with severe renal impairment (creatinine clearance <30 ml/min) the dosing intervals should be increased to 24 hourly.

Hepatic Impairment: The dosage does not require modification in cases of hepatic impairment.

Hypersensitivity to dicloxacillin and other penicillins.

Acute Overdose

Symptoms: Nausea, vomiting, epigastric distress and diarrhoea.

Management: Haemodialysis or peritoneal dialysis may be useful in the event of a serious toxic reaction particularly if renal function is compromised.
