Practice Protocol for Pharmacists in Missouri

Missouri does not define a named protocol for Pharmacists. Here is what the state does require and what a written protocol usually covers.

Represents Missouri's Medication Therapy Services (MTS) tier, not ordinary dispensing licensure. Authority is protocol-based (a physician-authored written protocol under § 338.198), not a bilaterally-negotiated collaborative-practice agreement, and NPs/PAs cannot delegate protocol authority to a pharmacist — only a physician can.

What a Pharmacist protocol must contain in Missouri

Missouri requires a written protocol but gives it no statutory name. Governed by the Missouri Board of Pharmacy. Each numbered item is a requirement the protocol must satisfy.

  1. Missouri does not have a statute establishing a physician-pharmacist "Collaborative Practice Arrangement" analogous to the Collaborative Practice Arrangement required of Nurse Practitioners and Physician Assistants under Chapter 334. The Pharmacist instead practices under the Missouri Pharmacy Practice Act, which permits a pharmacist to administer drugs and biologicals pursuant to a physician's order, standing order, or protocol.

  2. Where the Pharmacist participates in dispensing or administering medications under a Collaborative Practice Arrangement between the Physician and a Nurse Practitioner or Physician Assistant, that participation is governed by § 338.198. This Agreement's terms regarding the Pharmacist accordingly define the working relationship between the Parties and are not themselves required by Missouri law as a condition of the Pharmacist's authority to practice under the Pharmacist's own Board of Pharmacy license.

  3. The protocol also carries 1 education, 1 registration and 1 authority clauses, authored in the document itself.

About Missouri's rules

PA/APRN collaboration is governed by nearly-identical §§ 334.104/334.735: a 6-FTE combined ratio cap, 10%/20% chart-review every 14 days, biweekly physician presence, and a 120-hour controlled-substance Rx cap. A pre-2024 numeric 75-mile proximity rule was reportedly rescinded by both boards — current text uses an undefined 'geographic proximity' standard; verify with counsel before relying on any specific mileage figure.
