The document discusses Optimizerx's SampleMD software, which allows doctors to electronically send drug sample vouchers and coupons to patients directly from their EHR systems. This helps doctors assist more patients and drug companies market to doctors in a compliant way. SampleMD partners with large EHR vendors like Allscripts to reach over 200,000 doctors. It generates revenue by charging drug companies to offer samples/coupons and receiving fees for every one used. The business model is highly leveraged as growing adoption could enable high volumes of incremental revenue with modest overhead costs.
