Moncada was born in Tegucigalpa, Honduras, to Salvador Moncada and Jenny Seidner on 3 December 1944, but moved to El Salvador in 1948. He studied medicine at the Facultad de Medicina, Universidad de El Salvador from 1962 to 1970. In 1971 he went to London to work on a PhD with John Vane in the Department of Pharmacology in the Institute of Basic Medical Sciences, Royal College of Surgeons. After a short period of research in the University of Honduras he moved to the Wellcome Research Laboratories, where he became Director of Research in 1986. In 1996 he moved to University College London, where he set up the Wolfson Institute for Biomedical Research in the Cruciform Building, which he directed until 2012.
Research
His scientific career began at the Royal College of Surgeons where he collaborated in the discovery that aspirin-like drugs inhibit prostaglandin biosynthesis. This finding elucidated the mechanism by which these drugs act as analgesic, antipyretic, and anti-inflammatory agents and also explained the mechanism by which they cause gastric damage. In 1975, at the Wellcome Research Laboratories, he led the team that discovered the enzyme thromboxane synthase and the vasodilatorprostacyclin. This work contributed to the understanding of how low doses of aspirin prevent cardiovascular episodes such as myocardial infarction and stroke. As Director of Research at the Wellcome Research Laboratories he presided over the discovery and development of lamotrigine, atovaquone and zomig, and initiated the work that resulted in the development of lapatinib for the treatment of breast cancer. He was also responsible for the identification of nitric oxide as a biological mediator and the elucidation of the metabolic pathway leading to its synthesis. A great deal of the early work on the biological significance of nitric oxide in the cardiovascular system came from his laboratory, as well as some fundamental information about the role of nitric oxide in the peripheral and central nervous systems and in cancer. His later work has focused on the areas of mitochondrial biology and cell metabolism. Most recently, his work has led to the finding of the molecular mechanism that coordinates cell proliferation with the provision of metabolic substrates required for this process.

Other interests
Moncada is interested in medical education and in the development of science and technology in Latin America. He has been a consultant of the Panamerican Health Organization and in recent years he founded Honduras Global – an international network of experts involved in supporting the development of Honduras.
He was married to Dorys Lemus, a biochemistry teacher at the Medical School in El Salvador. The marriage resulted in two children, Claudia Regina and Salvador Ernesto,. On 5 April 1998, in London, he married Princess Marie-Esméralda of Belgium, daughter of King Leopold III of the Belgians and younger half-sister of King Albert II of the Belgians.
