Targeting transactions involving renowned pharmaceutical companies that are of interest to the industry, such as Merck, Roche, etc., Synapse has identified a group of "leading companies" through drugs that have achieved global sales exceeding 1 billion US dollars in 2022. Transactions involving drugs from these leading companies can be filtered by clicking on the "Leading Company" tag on the left-hand side.
In addition to the drug transaction module, you can also view related transaction history on the drug detail page and the institution detail page.
