Research and Development [Abstract]
Research and Development Expense	Research and Development Expense Research and development costs include expenditures in connection with an in-house research and development laboratory, salaries and staff costs, application and filing for regulatory approval of proposed products, regulatory and scientific consulting fees, as well as contract research, patient costs, drug formulation and tableting, data collection, monitoring, and clinical insurance. In accordance with FASB ASC Topic 730-10-55, Research and Development, Synergy recorded prepaid research and development costs of approximately $1.0 million as of March 31, 2017 and $0.5 million as of December 31, 2016, for nonrefundable advances for production of drug substance and analytical testing services for its drug candidates. In accordance with this guidance, Synergy expenses these costs when drug compound is delivered and services are performed. The Company recorded inventory, manufactured for sale of a product candidate, when the product candidate was considered to have a high likelihood of regulatory approval and the related costs are expected to be recoverable through sales. In determining whether or not to record such inventories, the Company evaluated, among other factors, information regarding the product candidate's safety and efficacy, the status of regulatory submissions and communications with regulatory authorities and the outlook for commercial sales. Prior to October 1, 2016, all costs associated with batches of inventory and manufactured for sale of our product candidates, were charged to research and development as incurred. Beginning in the fourth quarter of 2016, Synergy began capitalizing inventory costs for TRULANCE in preparation for its planned launch in the U.S. The Company will record inventory, manufactured for sale of a product candidate, when the product candidate is considered to have a high likelihood of regulatory approval and the related costs are expected to be recoverable through sales. In determining whether or not to record such inventories, the Company evaluates, among other factors, information regarding the product candidate's safety and efficacy, the status of regulatory submissions and communications with regulatory authorities and the outlook for commercial sales.
