Policies promoting generic substitution take into account many components such as quality and efficacy considering health stakeholders including physicians and pharmacists and identifying factors impacting generics prescription. The current study aimed to assess the association between the perception of physicians towards generics with their sex and age and their willingness to switch to generics after initial treatment. Furthermore, it aimed to evaluate the predictors for switching brands to generics after initial treatment and perceiving the exclusivity to perform this substitution. Prescription of generics to lower medical cost was more common among younger physicians compared to those 50\u00a0years and older. Interestingly, physicians aged 40 and above were more prone to prescribe generics to patients without medical coverage, while compared to physicians younger than 30\u00a0years of age. Age was significantly associated with switching initial treatment to generics, which was 2.46 times higher for physicians older than 50\u00a0years compared to those younger than 30\u00a0years. In addition, physicians practicing more than 20\u00a0years were about 1,5 times more accepting the substitution by pharmacists after initial treatment by brand while compared to physicians practicing for less than 10\u00a0years. Strategies to increase generic substitution and promoting its acceptance among physicians should take into consideration the different significant predictors. However, Further research is required to explore more factors, predicting prescription of generics in Lebanon, such as visits by medical representatives, regulations of the hospital that the physician is practicing, which are also proven to have high influence on the prescription practice of generics.<\/jats:p>","DOI":"10.1177\/17411343221107569","type":"journal-article","created":{"date-parts":[[2022,6,12]],"date-time":"2022-06-12T04:02:47Z","timestamp":1655006567000},"page":"23-32","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Predictors
