Ezith

Ezith Tablet, Powder For Suspension

Ezith is an azalide antibiotic, a subclass of macrolide antibiotic. It acts by binding to the 50s ribosomal subunit of susceptible microorganisms and thus interfering with microbial protein synthesis. Ezith has been shown to be active against most strains in the following microorganisms, both In vitro and in clinical infections:

Gram-positive microorganisms: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pneumoniae, Streptococcus pyogenes.

Gram-negative microorganisms: Haemophilus ducreyi, Haemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae, Escherichia coli.

Other microorganisms: Chlamydia pneumoniae, Chlamydia trachomatis, Mycoplasma pneumoniae, Bacteroides fragilis, Legionella pneumophila, oxoplasma gondii.

In Shigellosis, 500 mg once on day 1, followed by 250 mg once daily for next 4 days.

Ezith can be taken with or without food.

To reconstitute Ezith 15 ml powder for suspension: Add 10 ml or 2 tea spoonfuls of just boiled and cooled water to the content of the bottle and shake well to mix uniformly. 

To reconstitute Ezith 30 ml powder for suspension: Add 20 ml or 4 tea spoonfuls of just boiled and cooled water to the content of the bottle and shake well to mix uniformly. 

To reconstitute Ezith 50 ml powder for suspension: Add 35 ml or 7 tea spoonfuls of just boiled and cooled water to the content of the bottle and shake well to mix uniformly.

Side Effects

Ezith is well tolerated with a low incidence of side efects. The side effects include nausea, vomiting, abdominal discomfort (pain/cramps), flatulence, diarrhea, headache, dizziness, and skin rashes and are reversible upon discontinuation of therapy. Reversible elevations in liver transaminases have been observed occasionally. Transient mild reductions in neutrophil counts have occasionally been observed in clinical trials, although causal relationship to Ezith has not been established.

Precaution

As with any antibiotic, observation for signs of super infection with non-susceptable organisms, including fungi, is recommended. Precaution should be taken in patients with more severe renal impairment.

Interaction

Antacids: Peak serum levels but not the total extent of absorption are reduced by aluminium and magnesium containing antacids in the stomach. Ezith should therefore be taken at least 1 hour before or 2 hours after taking these antacids. 

Ergot Derivatives: Because of the theoretical possibility of ergotism, concomitant administration of ergot derivatives and Ezith should be avoided. Digoxin & Cyclosporin: Macrolides have been known to increase the plasma concentration of Digoxin & Cyclosporin and so caution should be exercised while co-administration is necessary. 

Anti-Histamines: A potentially life threatening interaction between erythromycin and terfenadine or astemizole have been reported. Although such an interaction with Ezith is not established yet, it is wise to avoid concomitant use of Ezith and terfenadine or astemizole.

Food Interaction

  • Take on an empty stomach. Take at least 1 hour before or 2 hours after meals.

Volume of Distribution

After oral administration, azithromycin is widely distributed in tissues with an apparent steady-state volume of distribution of 31.1 L/kg . Significantly greater azithromycin concentrations have been measured in the tissues rather than in plasma or serum , . The lung, tonsils and prostate are organs have shown a particularly high rate of azithromycin uptake .

This drug is concentrated within macrophages and polymorphonucleocytes, allowing for effective activity against Chlamydia trachomatis . In addition, azithromycin is found to be concentrated in phagocytes and fibroblasts, shown by in vitro incubation techniques. In vivo studies demonstrate that concentration in phagocytes may contribute to azithromycin distribution to inflamed tissues .

Half Life

Terminal elimination half-life: 68 hours

Clearance

Mean apparent plasma cl=630 mL/min (following single 500 mg oral and i.v. dose)

Pregnancy & Breastfeeding use

Pregnancy: US FDA pregnancy category B. In the animal studies, no evidence of harm to the fetus due to Ezith was found. Because animal reproduction studies are not always predictive of human response, Ezith should be used during pregnancy only if clearly needed.

Lactation: It is not known whether Ezith is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Ezith is administered to nursing mother.

Contraindication

Ezith is contraindicated in patients hypersensitive to Ezith or any other macrolide antibiotic. Co-administration of ergot derivatives and Ezith is contraindicated. Ezith is contraindicated in patients with hepatic diseases.

Special Warning

Pediatric Use: Ezith oral dosage forms can be administered to pediatric patients from 6 months of age. Safety and effectiveness of azithromycin for injection in children or adolescents under 16 years have not been established.

Acute Overdose

There are no data available on overdose with Ezith. Typical symptoms of overdosage with macrolide antibiotics include hearing loss, severe nausea, vomiting and diarrhoea. Gastric lavage and general supportive measures are indicated.

Interaction with other Medicine

Peak serum levels but not the total extent of absorption were reduced by the presence of magnesium and aluminum-containing antacids. Ezith should be taken at least 1 hr before or 2 hrs after these antacids. In patients receiving ergot alkaloids, Ezith should be avoided concurrently because of the possibilty of ergotism result in from interaction of Ezith with the cytochrome P-450 system However, no cases of such interaction have been reported. Macrolides have been known to increase the plasma concentration of digoxin and cyclosporine. Therefore, if co-administration is necessary caution should be exercised and serum levels of digoxin and cyclosporine should be checked. There have been no pharmacokinetic drug interactions between Ezith and warfarin, theophylline, carbamazepine, methylprednisolone and cimetidine.

Storage Condition

Ezith IV infusion: When diluted according to the instructions, azithromycin for injection is stable for 24 hours at or below room temperature 30° C, or for 7 days if stored under refrigeration 5° C.

How Does Ezith Work?

Ezith prevents the growth of bacteria by interfering with their protein synthesis. It binds to a specific part of the bacterial nucleus and inhibits the process required for bacterial growth. Thereby, bacteria are killed, or their growth is stalled depending on the organism and the medicine concentration.
