The department may, by regulation, remove any drug or device subject to Sections 111350 and 111550 from the requirements of Section 111470, when the requirements are not necessary for the protection of the public health. Any drug removed from the prescription requirements of the federal act by regulations adopted pursuant to the federal act is removed from the requirements of Section 111470. The department may, however, by regulation, continue the applicability of Section 111470 for any drug or device, or make these sections inapplicable to any drug or device,
whether or not the inclusion or exclusion of the drug or device is in accordance with the regulations adopted pursuant to the federal act.
