New online prescribing initiative improves consumer experience by

helping reduce potential drug interactions and expediting the

processing of prescription requests

Abaton.com, Inc. and Express Scripts announced today

at Intel Corporation's Internet Health Day II, a new e-commerce initiative that allows physicians to prescribe online using Abaton's prescribing system, ClinRx.com. This system, which is currently in use at healthcare organizations in the U.S., also allows physicians to review a patient's history for harmful drug interactions and allergies and access formulary guidelines at the time of prescribing, preserving patient confidentiality at every step. The teaming of Abaton and Express Scripts, the nation's leading independent full-service pharmacy benefit manager, will yield a number of quality and service benefits for consumers. For example, physicians will be able to access the list of drugs preferred by a member's plan before writing the prescription.

"We're excited by the opportunity to work closely with Abaton," said Barrett Toan, chief executive officer of Express Scripts. "Allowing physicians to prescribe online and access members' prescription history through a secure, confidential connection will improve the prescribing process for physicians and patients by reducing physician callbacks, saving time for physicians, pharmacists and patients, and enhancing patient safety. The real-time physician connectivity provided by Abaton's ClinRx.com prescribing system is impressive and proven."

States Jim Bradley, chief executive officer of Abaton.com, "This initiative is truly a `win-win-win' for consumers, physicians and payers. The electronic exchange of clinical information at every step of the prescribing supply chain is expected to significantly improve the consumer experience in terms of convenience, quality and safety. This agreement makes cost-effective online prescribing and formulary guidelines possible, while ensuring physicians prescribe appropriate drugs within payer guidelines. Once the physician reviews and writes the prescription, it is transmitted flow saving providers time and money.
