Generic Zithromax Dispersible Information

Introduction

Zithromax Dispersible is an oral antibiotic formulation containing the macrolide azithromycin. It belongs to the antibiotics group and is marketed primarily for the treatment of bacterial infections of the respiratory tract, ears, throat, skin, and certain sexually transmitted infections. In the United Kingdom, the product is supplied by Pfizer (the original brand holder) and is recognised for its convenient dispersible tablet that can be mixed with water, making it suitable for patients who have difficulty swallowing solid tablets. The medication is also used off‑label in some clinical scenarios, such as prophylaxis for certain infections in immunocompromised individuals.

What is Zithromax Dispersible?

Zithromax Dispersible is a tablet that rapidly dissolves in a small amount of water, producing a palatable suspension. It contains 250 mg of azithromycin per tablet, the same active compound found in other azithromycin products such as Zithromax  tablets, Zmax, Azyth, and Sumamed. The formulation includes inactive ingredients (e.g., mannitol, sodium starch glycolate) that aid dispersion and stability. It is manufactured under Good Manufacturing Practice (GMP) standards and holds marketing authorisation from the Medicines and Healthcare products Regulatory Agency (MHRA) for use in adults and children weighing at least 15 kg.

How Zithromax Dispersible Works

Azithromycin is a macrolide antibiotic that binds to the 50S subunit of bacterial ribosomes. This binding blocks the translocation step of protein synthesis, inhibiting the growth of susceptible bacteria (bacteriostatic effect). At higher concentrations, the drug can become bactericidal. Azithromycin is characterised by a high tissue affinity and a long half‑life of approximately 68 hours, allowing once‑daily dosing and short treatment courses (often three days). The drug is eliminated primarily via biliary excretion, with minimal renal clearance, which reduces the need for dose adjustment in mild renal impairment.

Conditions Treated with Zithromax Dispersible

• Community‑acquired pneumonia (CAP): Effective against Streptococcus pneumoniae and atypical pathogens such as Mycoplasma pneumoniae and Chlamydophila pneumoniae. In the UK, CAP accounts for roughly 300 000 hospital admissions annually.
• Acute bacterial sinusitis: Targets common causative organisms (S. pneumoniae, H. influenzae).
• Acute otitis media: Used when first‑line amoxicillin fails or contraindicated.
• Pharyngitis/Tonsillitis caused by Streptococcus pyogenes (when penicillin allergy exists).
• Skin and soft‑tissue infections: Covers Staphylococcus aureus (including some macrolide‑susceptible strains) and streptococci.
• Uncomplicated sexually transmitted infections: Particularly Chlamydia trachomatis infections of the urogenital tract.
• Travel‑related diarrhoea (non‑invasive): Empirical treatment for suspected bacterial aetiology when other agents are unsuitable.

These indications are reflected in the UK Summary of Product Characteristics (SPC) and the British National Formulary (BNF).

Who is Zithromax Dispersible For?

Zithromax Dispersible is appropriate for adults and adolescents (≥15 kg) who require treatment for the infections listed above and who can tolerate macrolide antibiotics. It is especially useful when:

• Rapid symptom control is desired, owing to the drug’s high tissue concentrations.
• Patients have difficulty swallowing conventional tablets, as the dispersible formulation can be mixed with water or juice.
• A short‑course regimen is preferred to improve adherence (e.g., three‑day azithromycin therapy).

The medication should be avoided or used with caution in:

• Individuals with known hypersensitivity to azithromycin, erythromycin, or other macrolides.
• Patients with a history of QT‑interval prolongation, significant cardiac arrhythmias, or concomitant use of other QT‑prolonging drugs.
• Severe hepatic impairment (Child‑Pugh C), where dosage adjustment may be required.

Risks, Side Effects, and Interactions

Common

• Gastrointestinal upset: Nausea, vomiting, diarrhoea, abdominal pain.
• Headache and mild dizziness.
• Taste disturbance (metallic or bitter taste).

These events are usually mild, transient, and resolve without intervention.

Rare

• Hepatobiliary reactions: Transient elevations in liver enzymes, cholestatic hepatitis.
• Cutaneous reactions: Rash, urticaria, photosensitivity.
• Hematologic changes: Mild neutropenia or thrombocytopenia (generally reversible).

Serious

• Cardiac effects: QT‑interval prolongation and rare cases of torsades de pointes, particularly in patients with pre‑existing cardiac disease or those taking other QT‑prolonging agents (e.g., fluoroquinolones, certain antiarrhythmics).
• Severe allergic reactions: Anaphylaxis, angio‑oedema.
• Clostridioides difficile infection: Antibiotic‑associated colitis may develop after prolonged or repeated courses.

Drug–drug interactions

• Concurrent macrolides or ketolides – additive risk of hepatotoxicity.
• Antacids containing aluminium or magnesium – may reduce azithromycin absorption; separate administration by at least 2 hours is advised.
• Warfarin – azithromycin can potentiate anticoagulant effect; monitor INR closely.
• Cytochrome P450 3A4 substrates (e.g., statins, certain benzodiazepines) – azithromycin is a weak inhibitor; clinical significance is limited but vigilance is recommended.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their healthcare professional before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for most infections: 500 mg on day 1 (taken as two 250 mg dispersible tablets) followed by 250 mg once daily on days 2–5. For certain indications (e.g., uncomplicated chlamydia), a single 1 g dose (four 250 mg tablets) may be prescribed.
• Pediatric dosing (≥15 kg): 10 mg/kg on day 1, then 5 mg/kg once daily on days 2–5.
• Administration: Dissolve the tablet in 30 mL of water, stir until fully dispersed, and drink immediately. Food does not markedly affect absorption, but taking the medication with food may reduce gastrointestinal irritation.
• Missed dose: If a dose is remembered within 12 hours, take it promptly. If more than 12 hours have passed, skip the missed dose and resume the regular schedule—do not double‑dose.
• Overdose: Symptoms may include severe nausea, vomiting, diarrhoea, and abdominal pain. Seek urgent medical attention; treatment is mainly supportive, with gastric lavage or activated charcoal considered if presentation is early.
• Alcohol: No direct interaction, but excessive alcohol may exacerbate gastrointestinal side effects.
• Renal/hepatic impairment: No routine dose reduction for mild to moderate renal dysfunction. Severe hepatic impairment warrants a 50 % dose reduction and close monitoring.

FAQ

• Is Zithromax Dispersible available in both brand‑name and generic forms in the UK?
  Yes, the brand‑name formulation is marketed by Pfizer under the name Zithromax Dispersible. Generic azithromycin tablets with an equivalent 250 mg dose are also authorised and can be sourced from multiple manufacturers, providing a lower‑cost alternative.

• What is the best way to store Zithromax Dispersible?
  The tablets should be kept at a controlled room temperature, between 15 °C and 30 °C, protected from light, moisture, and direct heat. Do not store them in bathrooms or near kitchen sinks where humidity is high.

• Can Zithromax Dispersible be taken with antacids?
  Antacids containing aluminium or magnesium may decrease azithromycin absorption. To avoid interaction, separate the administration by at least two hours before or after the antacid dose.

• Does the dispersible formulation contain any allergens?
  Inactive ingredients include mannitol, sodium starch glycolate, and colloidal silicon dioxide. Patients with known hypersensitivity to any of these excipients should avoid the product and discuss alternatives with a healthcare professional.

• How long does it take for azithromycin to reach therapeutic levels?
  After a single dose, azithromycin concentrations in most tissues rise rapidly, reaching peak levels within 2–3 hours. Sustained therapeutic exposure is maintained for several days due to the long half‑life.

• Are there any travel‑related considerations for Zithromax Dispersible?
  When traveling to regions with a high prevalence of diarrhoeal diseases, a short course of azithromycin can be used for empirical treatment of non‑invasive bacterial gastroenteritis, provided local resistance patterns support its efficacy.

• What distinguishes the UK formulation from those sold in the US or Asia?
  The UK version complies with MHRA specifications for tablet size, colour, and excipient composition. While the active dose (250 mg) is consistent worldwide, branding, packaging, and certain inactive ingredients may vary between markets.

• Can Zithromax Dispersible affect drug testing for athletes?
  Azithromycin is not listed on the World Anti‑Doping Agency (WADA) prohibited substance list, and routine doping screens do not target macrolide antibiotics. Nevertheless, athletes should retain documentation of medication use.

• Is there a risk of developing antibiotic resistance with short‑course azithromycin?
  Any antibiotic use carries a potential for resistance selection. The short‑course regimens recommended for azithromycin aim to minimise exposure while preserving efficacy; however, inappropriate or repeated use can contribute to macrolide‑resistant bacterial strains.

• What should be done if a dose is vomited shortly after ingestion?
  If vomiting occurs within 30 minutes of taking the dose, repeat the dose. If more than 30 minutes have passed, the dose can be considered absorbed, and the regular schedule should continue.

• Does Zithromax Dispersible interact with hormonal contraceptives?
  Azithromycin is not a known inducer of hepatic enzymes that reduce contraceptive efficacy, and no clinically significant interaction has been demonstrated. Nevertheless, maintaining consistent contraceptive use is advisable.

• Can Zithromax Dispersible be used in patients with severe asthma?
  Azithromycin has anti‑inflammatory properties and is sometimes employed as an adjunct in chronic severe asthma; however, this off‑label use requires specialist assessment due to potential cardiac risks.
