Amoxycillin is a semi-synthetic antibiotic, an analog of ampicillin, with a broad spectrum of bactericidal activity against many gram-positive and gram-negative microorganisms. Amoxycillin is bactericidal against susceptible organisms during the stage of active multiplication. It acts through the inhibition of biosynthesis of cell wall mucopeptides.
Amoxicillin competitively inhibit penicillin binding proteins, leading to upregulation of autolytic enzymes and inhibition of cell wall synthesis. Amoxicillin has a long duration of action as it is usually given twice daily. Amoxicillin has a wide therapeutic range as mild overdoses are not associated with significant toxicity. Patients should be counselled regarding the risk of anaphylaxis, Clostridium difficile infections, and bacterial resistance.
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 Staroba works
Amoxicillin competitively inhibits penicillin-binding protein 1 and other high molecular weight penicillin binding proteins. Penicillin bind proteins are responsible for glycosyltransferase and transpeptidase reactions that lead to cross-linking of D-alanine and D-aspartic acid in bacterial cell walls. Without the action of penicillin binding proteins, bacteria upregulate autolytic enzymes and are unable to build and repair the cell wall, leading to bacteriocidal action.
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.

Side Effects
Side effects are mild, rare and infrequent. As with other penicillins, it may induce diarrhea, indigestion or skin rashes that usually stop during treatment and rarely calls for discontinuation of therapy.
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
Patients experiencing an overdose may present with hematuria, oliguria, abdominal pain, acute renal failure, vomiting, diarrhea, rash, hyperactivity, and drowsiness. Treat overdose with symptomatic and supportive treatment, which may include emesis or hemodialysis.
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 renal impairment, the excretion of antibiotic will be delayed and depending on the degree of impairment it may be necessary to reduce the total daily dose.
Patient with history of allergy esp β-lactam allergy, asthma. Pregnancy and lactation.
Interaction
The simultaneous use of Amoxicillin and an oral contraceptive might cause breakthrough bleeding or pregnancy on rare occasions. Concurrent administration of probenecid delays the excretion of Amoxicillin.
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).
Volume of Distribution
The central volume of distribution of amoxicillin is 27.7L.
Elimination Route
Amoxicillin is approximately 60% bioavailable. A 250mg dose of oral amoxicillin reaches a Cmax 3.93±1.13mg/L with a Tmax 1.31±0.33h and an AUC of 27.29±4.72mg*h/L. A 875mg dose of oral amoxicillin reaches a Cmax 11.21±3.42mg/L with a Tmax 1.52±0.40h and an AUC of 55.04±12.68mg*h/L.
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
The half life of amoxicillin is 61.3 minutes.
The elimination half-life for dicloxacillin is about 0.7 hour.
Clearance
The mean clearance of amoxicillin is 21.3L/h.
Elimination Route
125mg to 1g doses of amoxicillin are 70-78% eliminated in the urine after 6 hours.
Dicloxacillin sodium is rapidly excreted as unchanged drug in the urine by glomerular filtration and active tubular secretion.
Pregnancy & Breastfeeding use
Because of its lack of teratogenicity, Amoxicillin can beused safely throughout pregnancy at the normal adult dose. The small amount of Amoxicillin secreted in maternal milk rarely causes problem in the infant. It can therefore be used safely during lactation in most instances.
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
Amoxicillin is contraindicated for patients hypersensitive to penicillin, infectious mononucleosis, neonatal period or babies born of mothers hypersensitive to penicillin
Hypersensitivity to dicloxacillin and other penicillins.
Acute Overdose
If encountered, gastro-intestinal symptoms and disturbance of the fluid and electrolyte balance may be evident. They may be treated symptomatically and supportive with attention to the water/ electrolyte balance. In the absence of an adequate fluid intake and urinary output, crystalluria is a possibility and the antibiotic may be removed from the circulation by haemodialysis. Oral administration can cause gastro intestinal symptoms such as transient diarrhoea, nausea and colic which are dose related and a result of local irritation not toxicity.
Storage Condition
Store in a cool & dry place protected from light. Amoxicillin suspension and drops should be freshly prepared, stored in a cool dry place preferably in a refrigerator. Reconstituted suspension and drops should be used within 5 days if kept at room temperature or within 7 days if kept in a refrigerator.
Store between 20-25° C.
