Naranjo algorithm
Naranjo Algorithm
The Naranjo Algorithm (pronunciation: nəˈrɑːnhoʊ ˈælɡərɪðəm) is a method used in pharmacovigilance to determine the likelihood that an adverse drug reaction (ADR) is actually due to the drug rather than the result of other factors.
Etymology
The algorithm is named after its developer, Dr. Carlos A. Naranjo, a clinical pharmacologist from Canada. The term "algorithm" is derived from the name of the 9th-century Persian mathematician Al-Khwarizmi, who was instrumental in the development of algebra.
Description
The Naranjo Algorithm is a questionnaire designed to standardize the assessment of causality for all suspected adverse drug reactions. It consists of ten questions that are answered with yes (which scores 1 or 2), no (which scores 0), or do not know (which also scores 0). The total score is then used to classify the ADR as definite (score of 9 or greater), probable (score of 5 to 8), possible (score of 1 to 4), or doubtful (score of 0).
