AZ SB1119

Adds definition of "nutrient" to specify substances that provide nourishment for growth or metabolism, manufactured by FDA-registered manufacturers or compounded by pharmacy accrediting board-accredited pharmacies, for intravenous use by naturopathic doctors.

Allows naturopathic physicians to administer intravenous nutrients as part of their authorized drug uses, alongside vitamins, chelation therapy, and emergency resuscitation drugs.

Requires the naturopathic physicians medical board to adopt rules for safe administration of intravenous nutrients and to identify and exclude substances that do not meet criteria for suitable intravenous use.

Adds new board duty to regulate intravenous nutrient administration standards while maintaining existing restrictions on controlled substances and other prohibited drug categories for naturopathic practitioners.
