Azitor Tablet, Powder For Suspension
Azitor 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. Azitor 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.
Azitor is used for infections caused by susceptible organisms in-
Upper respiratory tract infections including sinusitis, pharyngitis and tonsillitis
Lower respiratory tract infections including bronchitis, acute bacterial exacerbations of chronic obstructive pulmonary
Skin and soft tissue infections including cellulitis, pyoderma, erysipelas, wound infections
Sexually transmitted diseases, especially in the treatment of non-gonococcal urethritis and cervicitis due to Chlamydia trachomatis
Genital ulcer disease in men due to Haemophilus ducreyi (chancroid)
Mild or moderate typhoid due to multiple-antibacterial resistant organisms
Prophylaxis against a-hemolytic (viridans group) streptococcal bacterial endocarditis
Other infections including odontogenic infections, bartonella infections, toxoplasmosis, babesiosis
Azitor is also used to associated treatment for these conditions: Acute Bacterial Sinusitis (ABS), Acute Otitis Media, Acute bacterial exacerbation of COPD caused by Haemophilus Influenza Infections, Moraxella Catarrhalis Infection, Streptococcus Pneumoniae Infections, Bacterial Conjunctivitis, Bacterial Sinusitis, Cervicitis, Chancroid, Community Acquired Pneumonia (CAP), Genital Ulcer Disease (GUD), Pelvic Inflammatory Disease (PID), Pharyngitis, Streptococcal Pharyngitis, Streptococcal tonsillitis, Tonsillitis bacterial, Traveler's Diarrhea, Uncomplicated Skin and Skin Structure Infections, Urethritis

Azitor tablet can be taken with or without food. Azitor suspension should be taken at least 1 hour before or 2 hours after meal.
For respiratory tract infections, otitis media and skin & soft tissue infections: 500 mg once daily for 3 days or an alternative to this as 500 mg once on day 1, followed by 250 mg once daily for next 4 days. For sexually transmitted diseases like genital ulcer, non-gonococcal urethritis and cervicitis due to Chlamydia trachomatis : a single 1 gm (1000 mg) dose. For the treatment of urethritis and cervicitis due to Neisseria gonorrhoeae : a single 2 gm (2000 mg) dose. In typhoid, 500 mg once daily for 7 days. In Cholera, a single 1 gm (1000 mg) dose. In Shigellosis, 500 mg once on day 1, followed by 250 mg once daily for next 4 days.

To reconstitute Azitor 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 Azitor 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 Azitor 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.
Azitor 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 Azitor has not been established.
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.
Antacids: Peak serum levels but not the total extent of absorption are reduced by aluminium and magnesium containing antacids in the stomach. Azitor 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 Azitor 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 Azitor is not established yet, it is wise to avoid concomitant use of Azitor and terfenadine or astemizole.
- 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 .
Terminal elimination half-life: 68 hours
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 Azitor was found. Because animal reproduction studies are not always predictive of human response, Azitor should be used during pregnancy only if clearly needed.
Lactation: It is not known whether Azitor is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Azitor is administered to nursing mother.
Azitor is contraindicated in patients hypersensitive to Azitor or any other macrolide antibiotic. Co-administration of ergot derivatives and Azitor is contraindicated. Azitor is contraindicated in patients with hepatic diseases.
Pediatric Use: Azitor 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.
There are no data available on overdose with Azitor. 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. Azitor should be taken at least 1 hr before or 2 hrs after these antacids. In patients receiving ergot alkaloids, Azitor should be avoided concurrently because of the possibilty of ergotism result in from interaction of Azitor 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 Azitor and warfarin, theophylline, carbamazepine, methylprednisolone and cimetidine.
Azitor 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.
Azitor capsule, tablet and dry powder for suspension: should be stored at room temperature (below 30° C). Any unused portion of reconstituted Azitor suspension should be discarded after 5 days.
Azitor eye drops: Store unopened bottle under refrigeration at 2°C to 8°C. Once the bottle is opened, store at 2°C to 25°C for up to 14 days. Discard after the 14 days.

Does Azitor kill gut bacteria?
Like all broad-spectrum antibiotics, Azitor does not discriminate between pathogenic bacteria and healthy bacteria. Hence, when you take antibiotics to fight an infection, many of the bacteria in your gut are killed too (think of it as collateral damage).
Does Azitor make me tired?
Azitor oral tablet doesn't cause drowsiness, but it can cause other side effects.
How safe is Azitor?
The U.S. Food and Drug Administration (FDA) is warning the public that azithromycin (Zithromax or Zmax) can cause abnormal changes in the electrical activity of the heart that may lead to a potentially fatal irregular heart rhythm. source
Can Azitor treat cold?
Azitor is used to treat a wide variety of bacterial infections. It is a macrolide-type antibiotic. It works by stopping the growth of bacteria. This medication will not work for viral infections (such as common cold, flu).

You may drive, but be sure you are not experiencing dizziness before you start driving.
How Does Azitor Work?
Azitor 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.
