Active ingredient
Azithromycin dihydrate, a semi-synthetic 15-membered azalide macrolide. Mechanism: reversible binding to the 50S bacterial ribosomal subunit at the 23S rRNA peptidyl-transferase site, blocking transpeptidation and translocation. Distinct from erythromycin in the addition of a methyl-substituted nitrogen in the lactone ring — drives improved acid stability, longer tissue half-life (≈68 hours intracellular), and reduced motilin-receptor agonism (less GI upset than erythromycin).
Strengths stocked
250mg and 500mg film-coated tablets are the high-volume retail and hospital lines (Z-pak 500mg day 1 then 250mg days 2-5; or 500mg OD x 3 days; or 1g single-dose for chlamydia, cholera, trachoma MDA). 200mg/5ml powder for oral suspension covers paediatric dosing — 10 mg/kg day 1 then 5 mg/kg/day x 4 days for CAP, otitis media, pertussis. 500mg lyophilised IV vial for hospitalised CAP, severe Legionella, and IV-to-oral switch protocols. Reconstitute IV with 4.8ml sterile water for injection, then dilute to 1-2 mg/ml in 0.9% NaCl or 5% glucose for slow infusion (≥60 min).
Indications
CAP (atypical cover, paired with a beta-lactam in severe disease); AECOPD; pertussis treatment + post-exposure prophylaxis; trachoma MDA (WHO GET2030); MAC prophylaxis in advanced HIV (CD4 <50); paediatric otitis media and pharyngitis; cholera outbreak adjunct; travellers' diarrhoea where fluoroquinolone resistance is high. WHO AWaRe Watch class — antimicrobial stewardship oversight. Standard adult dose 500mg OD x 3 days or Z-pak 500mg day 1 then 250mg days 2-5. Single 1g dose for chlamydia, cholera adjunct, trachoma MDA.
Storage
Tablets and oral-suspension powder at room temperature below 30°C, protected from moisture. Reconstituted oral suspension stable for 5 days at room temperature (do not refrigerate — reduced palatability). Lyophilised IV vial at 15-30°C. Reconstituted IV (100 mg/ml) stable for 24 hours at room temperature; further-diluted infusion stable for 24 hours at 5°C or 7 days at 30°C in 0.9% NaCl or 5% glucose. Standard ambient-temperature dispatch lane — no cold-chain required in transit.
Shelf life
Tablets and oral suspension 36 months from manufacture; IV vial 24 months. Minimum 24 months at dispatch on tablets and suspension, 18 months on IV. Or we won't ship it.
Pack format
Tablets in Alu-Alu or Alu-PVC blisters, hospital and retail packs (Z-pak 6-tablet, 3-tablet, and 100-tablet hospital). Oral suspension in HDPE bottle with reconstitution graduations and dosing syringe. IV vial Type-I clear glass, halobutyl rubber stopper, aluminium seal with flip-off cap. Outer carton and leaflet in destination-regulator language. AWaRe Watch antibiotic stewardship label, QT-prolongation cardiac warning, and gonococcal-resistance note prominently set on SmPC.
Hospital pharmacies, primary-care formularies, MDA programmes and tender desks across thirty markets.
India is our origin. We do not sell into the Indian market. Azithromycin is exported only.
United Kingdom
Azithromycin is core NHS primary-care and hospital pharmacy stock. Standard for AECOPD trigger therapy, atypical CAP cover, paediatric pertussis, and penicillin-allergy alternative. Where the primary licensed supplier cannot fill, the MHRA Specials / named-patient import route is available — see MHRA Specials. NHS BSAC AMR Stewardship Programme alignment included for hospital pharmacy committee approval. Note: BASHH 2024 dropped azithromycin from gonorrhoea protocols; doxycycline 7-day is now preferred for chlamydia.
GCC (UAE, KSA, Kuwait, Oman, Qatar, Bahrain)
Through local licensed importers, against MoH primary-care + hospital formulary tender awards (NUPCO and Saudi MoH; MoHAP, DHA and DOH Abu Dhabi for UAE; Kuwait MoH Central Drug Store; MoPH Qatar including Hamad Medical Corporation; MoH Oman; NHRA Bahrain). Paediatric oral suspension and Z-pak retail-format tenders are particularly high-volume. SFDA, MoHAP and GCC central registration supported with full CTD dossier.
Nigeria, Kenya, Ghana, South Africa, Ethiopia, Tanzania, Uganda, Rwanda
Public-sector hospital tenders (NAFDAC for Nigeria, KEMSA + MEDS for Kenya, FDA Ghana + Central Medical Stores, SAHPRA for South Africa, EFDA + EPSS for Ethiopia, TMDA + MSD for Tanzania, NDA + NMS for Uganda) and teaching-hospital supply. Azithromycin is the WHO-recommended single agent for trachoma mass drug administration under the WHO GET2030 elimination programme — annual MDA campaigns reach ≈100 million people across 40+ endemic countries (Pfizer's International Trachoma Initiative is the historical donor; Indian WHO-PQ generics now extend access). PEPFAR-aligned MAC prophylaxis in HIV programmes. WHO Prequalification supported.
Germany, France, Brazil, Mexico, Philippines
Supply via licensed importers under §72 AMG (Germany), ANSM equivalent (France), ANVISA (Brazil), COFEPRIS (Mexico), FDA Philippines, with Qualified Person (QP) certification on EU arrival. CTD dossier and CoPP prepared for BfArM, ANSM, ANVISA, COFEPRIS and FDA Philippines recognition.
QT prolongation, gonococcal-resistance dropout, statin and warfarin interactions, paediatric mg/kg dosing — azithromycin is everyday but the safety margins matter.
Adult oral dose is the Z-pak: 500mg day 1 then 250mg days 2-5, or 500mg OD x 3 days, or single 1g for chlamydia / cholera adjunct / trachoma MDA. IV dose 500mg OD x at least 2 days then switch to oral. Paediatric dose: 10 mg/kg day 1 (max 500mg) then 5 mg/kg/day x 4 days (max 250mg/day) for CAP, otitis media, pertussis. QT-prolongation is the killer issue: FDA issued a black-box-equivalent safety communication in March 2013 after a NEJM cohort showed a small but statistically significant excess of cardiovascular death during 5-day Z-pak courses (relative risk ≈2.5 vs amoxicillin); the EMA followed with a 2013-2014 review. Avoid in patients with known QT prolongation, hypokalaemia, hypomagnesaemia, bradyarrhythmia, congenital long-QT syndrome, or on Class IA / Class III antiarrhythmics; co-prescription with other QT-prolonging agents (haloperidol, ondansetron, fluoroquinolones, methadone, tricyclics) requires ECG monitoring. Gonococcal resistance has moved azithromycin off first-line: the BASHH 2024 UK gonorrhoea guideline dropped azithromycin co-administration from the ceftriaxone 1g IM regimen due to global gonococcal MIC creep above 1 mg/L; CDC retained azithromycin briefly but updated 2020 guidance to ceftriaxone monotherapy 500mg IM (raised to 1g in subsequent updates). For chlamydia, BASHH 2024 prefers doxycycline 100mg BD x 7 days over single-dose azithromycin 1g due to ≈22% azithromycin treatment failure in rectal chlamydia. Drug interactions: weak CYP3A4 inhibitor — co-prescription with simvastatin, atorvastatin, or lovastatin raises rhabdomyolysis risk (use rosuvastatin or pravastatin if needed); INR rises in warfarin patients (monitor at days 3-5); ergotamine contraindicated; colchicine toxicity reported. Hepatotoxicity: rare cholestatic hepatitis, more frequent with prolonged courses (MAC prophylaxis, AECOPD chronic suppression). C. difficile colitis risk is moderate-low. Diluent for IV: 0.9% NaCl, 5% glucose, sterile water; do not bolus — slow infusion ≥60 min.
The documentation pack a regulator actually asks for.
Azithromycin is a WHO EML core-list AWaRe Watch antibiotic and WHO PQ-listed across tablets, oral suspension and IV. Our role is manufacturer-facing — we sit between the Indian WHO-GMP facility and your clinical, regulatory or procurement team and take the paperwork off both sides.

Temperature control
Pre-shipment validation on each shipper configuration. Tablets and oral suspension powder ship at 15-30°C ambient; integrity-critical factors are moisture exclusion (Alu-Alu blister preferred for tablets in tropical destinations), and oral suspension reconstitution validation. IV lyophilised vial at 15-25°C ambient, moisture exclusion, light protection. No cold-chain required in transit; ambient-temperature dispatch lane standard.
Pharmacovigilance
Local PV partner or a named PV contact organised in the destination market against registration. Periodic Safety Update Reports compiled to ICH E2C. QT-prolongation cardiac events, hepatotoxicity, severe hypersensitivity, and gonococcal MIC creep remain the PSUR priority signals. Trachoma MDA campaigns run annual safety surveillance under WHO/ITI protocols. AMR Stewardship Programme surveillance reporting included for AWaRe Watch compliance.
Atypical CAP cover, AECOPD, AWaRe-aligned cluster.
Azithromycin is rarely a standalone in moderate-severe CAP — empirical pairs it with a beta-lactam (amoxicillin or ceftriaxone) for typical pathogen cover, and resistant respiratory pathogens or penicillin-allergic patients escalate to alternative options.
Ceftriaxone
Third-gen cephalosporin, paired with azithromycin for severe CAP. 1g / 2g vials. AWaRe Watch.
Amoxicillin
Beta-lactam first-line for mild CAP; switch to azithromycin on penicillin allergy. 250mg / 500mg / 1g.

Azithromycin supply — the specific questions.
What strengths and dosage forms of azithromycin do you supply?
250mg and 500mg film-coated tablets in Alu-Alu or Alu-PVC blister, in Z-pak 6-tablet (500mg day 1 then 250mg days 2-5), 3-tablet (500mg OD x 3 days), and hospital 100-tablet packs. 200mg/5ml powder for oral suspension in HDPE bottle with reconstitution graduations and a paediatric dosing syringe — reconstitute with water at point of dispensing, stable 5 days at room temperature. 500mg lyophilised IV vial for hospitalised CAP, severe Legionella and IV-to-oral switch protocols. Reconstitute IV with 4.8ml sterile water for injection, dilute to 1-2 mg/ml in 0.9% NaCl or 5% glucose, slow infusion ≥60 minutes (do not bolus).
Is your azithromycin WHO PQ-listed for Global Fund and trachoma MDA tenders?
Yes. Multiple M Care partner facilities hold WHO Prequalification for azithromycin tablets, oral suspension and IV. The WHO PQ certificate is included in the shipping documentation pack. Azithromycin is the WHO-recommended single agent for trachoma mass drug administration under the WHO GET2030 elimination programme — annual MDA campaigns reach ≈100 million people across 40+ endemic countries. We engage on WHO/ITI trachoma MDA pooled tenders, country-level public-sector tenders (KEMSA, NAFDAC, CMS Ghana, EPSS, MSD Tanzania, NMS Uganda), Global Fund cholera-outbreak adjunct grants, and NGO procurement (MSF, Direct Relief, Partners In Health) through the same manufacturing lines.
How is the QT-prolongation cardiac warning handled in your labelling?
The FDA issued a black-box-equivalent safety communication in March 2013 after a NEJM cohort showed a small but statistically significant excess of cardiovascular death during 5-day Z-pak courses (relative risk ≈2.5 vs amoxicillin); the EMA followed with a 2013-2014 review. Our destination-language pack inserts and SmPCs carry the QT-prolongation warning, the contraindication in patients with known QT prolongation, hypokalaemia, hypomagnesaemia, bradyarrhythmia, congenital long-QT syndrome, or on Class IA / Class III antiarrhythmics, plus drug-interaction warnings for statins (rhabdomyolysis with simvastatin / atorvastatin / lovastatin), warfarin (INR rise at days 3-5), ergotamine (contraindicated), and colchicine (toxicity reported). The prescribing-side responsibility (ECG monitoring in at-risk patients) sits with the prescribing clinician; the manufacturer-side responsibility (clear labelling) is ours.
Which markets can you ship azithromycin into?
The UK (NHS primary-care and hospital pharmacy supply or named-patient / MHRA Specials route during shortage), the GCC (UAE, Saudi Arabia, Kuwait, Oman, Qatar, Bahrain) through licensed local importers — primary-care and paediatric oral-suspension tenders are the main channels — sub-Saharan Africa (Nigeria, Kenya, Ghana, South Africa, Ethiopia, Tanzania, Uganda, Rwanda) for tender, teaching-hospital supply, and WHO trachoma MDA campaigns with WHO PQ pathway support — Global Fund cholera-outbreak adjunct grants are an episodic high-volume channel. Egypt, Jordan, Iraq on the Levant side. Germany under §72 AMG, France under ANSM-equivalent route, Brazil (ANVISA), Mexico (COFEPRIS) and the Philippines (FDA Philippines). We do not supply into India. Full market coverage is at markets.
What documentation is included with an azithromycin consignment?
Every consignment ships with a batch-specific Certificate of Analysis (HPLC assay, related substances per Ph.Eur./USP, water content by Karl Fischer for the dihydrate form, residual solvents per ICH Q3C, dissolution profile, pH on reconstitution for suspension and IV, microbial limits, bacterial endotoxin for IV, particulate matter), Method of Analysis, Certificate of Pharmaceutical Product (CoPP), WHO-GMP certificate, manufacturing licence, WHO Prequalification certificate where applicable, Certificate of Origin (chamber-attested), destination-language pack insert with QT-prolongation cardiac warning + drug-interaction warnings (statins, warfarin, ergotamine, colchicine) + AWaRe Watch antibiotic stewardship label + paediatric mg/kg dosing chart (10 mg/kg day 1, 5 mg/kg/day x 4 days) on the suspension carton, Antimicrobial Stewardship Programme documentation for hospital pharmacy committee approval, plus temperature logs from pre-dispatch through on-arrival. PV contact nominated on registration.
Do you provide CTD dossiers for azithromycin registration?
Yes. Full CTD Module 3 dossiers are available against a non-disclosure agreement, for registration with MHRA, GCC central registration, SFDA, MoHAP, NAFDAC, PPB, SAHPRA, EFDA, TMDA, NDA, BfArM, ANSM, ANVISA, COFEPRIS, FDA Philippines and comparable bodies. Module 2 summaries and Module 1 administrative sections are prepared in destination-specific format. Azithromycin has a well-established CMC template across tablets, oral suspension and IV — lead time on a dossier against a new registration is typically 3-5 weeks from NDA signature. WHO PQ dossier prepared separately for Global Fund, Africa CDC, and WHO trachoma MDA qualification. AWaRe Watch antimicrobial stewardship documentation prepared as a CTD addendum. See dossier preparation.
What are typical lead times for azithromycin orders, and does it need cold-chain transit?
For registered markets with stock on hand, dispatch is typically 5-10 working days from confirmed order. For tender awards (WHO trachoma MDA, Global Fund cholera-outbreak adjunct, Africa CDC, NUPCO, KEMSA, CMS Ghana), the lead time is set in the tender award document. For UK NHS primary-care or hospital pharmacy ad-hoc supply with urgency flagged, air-freight out of Mumbai can be on a flight within 72 hours. Made-to-order batches run 6-10 weeks inclusive of QC release and destination artwork. Azithromycin tablets, oral-suspension powder and lyophilised IV vial do not require cold-chain in transit — they ship at 15-30°C ambient. Reconstituted oral suspension is stable for 5 days at room temperature (do not refrigerate — palatability drops); reconstituted IV stable 24 hours at room temperature. Transit temperature is logged on every consignment for QA traceability.
