John Lykoudis
Greek physician
John Lykoudis (Greek: Ιωάννης Λυκούδης; 1910–1980) was a Greek physician and politician. He treated patients who had peptic ulcer disease with antibiotics long before it was commonly recognized that bacteria were a dominant cause for the disease. He became mayor of Missolonghi in 1951, serving until 1959.
Career
After treating himself for peptic ulcer disease with antibiotics in 1958 and finding the treatment effective, Lykoudis began treating patients with antibiotics. After experimenting with several combinations of antibiotics he eventually arrived at a combination which he termed Elgaco and which he patented in 1961.
It has been estimated that he treated more than 30,000 patients.
In his time he had great difficulties in persuading the Greek medical establishment about the effectiveness of the treatment. He was given a fine of 4000 drachmas by a disciplinary committee, and indicted in the Greek courts. He was unable to get an article published in the Journal of the American Medical Association and was not able to get the established pharmaceutical companies sufficiently interested in the treatment.

Why this record matters
The phrase “greek physician” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 20, 2026. The linked authority identifier is Q6245577. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1910, 1980, 1951 and 1959.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
