Questions about Amoxicillin trials

How many clinical trials are testing Amoxicillin?

29 current trials in our China, Canada, France, Switzerland, Mexico, Brazil, Egypt, Japan, Germany, Spain, Italy, Netherlands, Denmark, South Korea and Taiwan registers name Amoxicillin as a drug or biological intervention, as of the registry sync on 10 November 2026. Completed and withdrawn studies are not counted.

Are Amoxicillin trials recruiting patients?

Yes. 20 of the 29 trials are recruiting: 7 with sites in China, 2 with sites in Canada, 2 with sites in France, 2 with sites in Switzerland, 1 with sites in Mexico, 1 with sites in Brazil, 2 with sites in Egypt, 1 with sites in Japan, 1 with sites in Germany, 1 with sites in Spain, 1 with sites in Denmark and 1 with sites in Taiwan. Eligibility and site contacts are on each trial's record. Only the study team can confirm whether a patient is eligible.

Who sponsors Amoxicillin clinical trials?

First People's Hospital of Hangzhou (2), Tanta University (2), Qilu Hospital of Shandong University (1) and Second Affiliated Hospital, Zhejiang University, School of Medicine (1), among 27 lead sponsors in total. The number in brackets is how many trials each organisation leads.

Is Amoxicillin licensed in Ireland?

Yes. The HPRA medicines list includes 13 single-substance products containing Amoxicillin, for example Amoxicillin 250 mg hard capsules (Clonmel Healthcare Ltd). A licence does not mean a product is currently marketed or reimbursed; see each product's record.

Is there a Amoxicillin shortage?

The registers we track list 4 entries for Amoxicillin: Amoxicillin and amoxicillin/clavulanic acid (EU: shortage resolved); 3 German notices. Shortages are product- and country-specific; check with a pharmacist.

Where does this information come from?

Every trial, status, phase and sponsor on this page is copied from public ClinicalTrials.gov records by a daily sync. Nothing here describes how Amoxicillin works or whether it is effective, and it is not medical advice.

How this page is built

Everything on this page is copied from public ClinicalTrials.gov registry records — it is not written from memory, and nothing here describes how Amoxicillin works or whether it is effective. Each trial links to its own record so you can check it yourself.

This page is built automatically: a daily sync job reads the registry records behind our country trial registers, collects every trial that lists Amoxicillin (or a registered synonym) as a drug or biological intervention, and tabulates the registry fields directly. Placebos and generic comparators are excluded. There is no AI drafting and no per-compound editorial pass, and the page has not been clinically reviewed. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy. The ClinicalTrials.gov data on this page was last retrieved on 10 Nov 2026. How every register is built: methodology · fixes we have made: corrections log.

Please verify before you rely on this. This page is general information for life-science and pharmaceutical professionals. It is not medical advice, and it has not been reviewed by a clinician — our editorial team holds life-science qualifications, not clinical ones. It is not exhaustive and may not reflect the most recent label change. Always check the official prescribing information (US Prescribing Information or EU SmPC) and speak to your doctor or pharmacist before acting on anything here. Drugs in the same class are not automatically interchangeable, and approvals, brand names and indications differ between the US, the EU/Ireland (EMA/HPRA) and other regions. Spotted an error? Tell us — we correct promptly and log it.
