Amopen

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

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.

Amopen competitively inhibit penicillin binding proteins, leading to upregulation of autolytic enzymes and inhibition of cell wall synthesis. Amopen has a long duration of action as it is usually given twice daily. Amopen 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.

Uses

Amopen is used for the treatment of the following bacterial infections when caused by susceptible organisms:

  • Respiratory tract, ENT infections: Acute and chronic bronchitis, pneumonia, otitis media, sinusitis, tonsillitis, pharyngitis & laryngitis, lobar & bronchopneumonia, chronic bronchial sepsis.
  • Urinary tract infections: Pyelonephritis, cystitis and urethritis.
  • Obstetric & gynaecological infections: Bacteriuria in pregnancy, septic abortion, intra-abdominal sepsis and puerperal sepsis.
  • Gastro-intestinal infections: Typhoid and paratyphoid.
  • Skin & soft tissue infections: Cellulitis, infected wounds and abscesses.
  • Generalized infections: Septicemia, bacterial endocarditis, meningitis, peritonitis and osteomyelitis.
  • Venereal infections: Gonorrhea and syphilis. Amopen may also be used as prophylactic cover for patients at risk of developing endocarditis when undergoing dental surgery.

Amopen is also used to associated treatment for these conditions: Acute Bacterial Sinusitis (ABS), Acute Otitis Media, Acute Otitis Media (AOM), Bacterial Infections, Community Acquired Pneumonia (CAP), Duodenal ulcer caused by helicobacter pylori, Genitourinary infections, Helicobacter Pylori Infection, Lower Respiratory Tract Infection (LRTI), Peptic Ulcer With H. Pylori Infection, Sinusitis, Skin and Subcutaneous Tissue Bacterial Infections, Urinary Tract Infection, Acute, uncomplicated Gonorrhea, Ear, nose, and throat infections

How Amopen works

Amopen 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.

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.

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.

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.

Interaction

The simultaneous use of Amopen and an oral contraceptive might cause breakthrough bleeding or pregnancy on rare occasions. Concurrent administration of probenecid delays the excretion of Amopen.

Food Interaction

  • Take with food.

Volume of Distribution

The central volume of distribution of amoxicillin is 27.7L.

Elimination Route

Amopen 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.

Half Life

The half life of amoxicillin is 61.3 minutes.

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.

Pregnancy & Breastfeeding use

Because of its lack of teratogenicity, Amopen can beused safely throughout pregnancy at the normal adult dose. The small amount of Amopen secreted in maternal milk rarely causes problem in the infant. It can therefore be used safely during lactation in most instances.

Contraindication

Amopen is contraindicated for patients hypersensitive to penicillin, infectious mononucleosis, neonatal period or babies born of mothers hypersensitive to penicillin

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. Amopen 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.
