1. Pharmacists may provide pharmaceutical health care to patients by initiating, discontinuing or modifying prescription drug therapy upon entering into an active protocol agreement with a licensed prescribing practitioner. Each protocol must define the parameters by which the practitioner delegates this authority and any such authority granted must be within the scope of the practitioner's prescribing authority and current practice. A copy of the written protocol shall be made available upon request of the Board or an agent of the Board. For purposes of this ARTICLE, "protocol" shall mean a written agreement with a practitioner authorized to prescribe drugs whereby the prescribing practitioner delegates to a pharmacist or pharmacists, authority to conduct specific initiation, discontinuation or modification of drug therapy functions for those patients common to the practitioner and pharmacist(s).
