Summary

Starting 180 days after July 9, 2012, anyone who wants to first bring a designated medical gas into interstate commerce must ask the Secretary for a certification. The request must include a description of the gas, the sponsor’s name and address, the manufacturing site(s) address, and any other information the Secretary needs. The Secretary has 60 days to find problems. If within 60 days the Secretary does not say the gas is not designated, or that the request is missing required information, or that denial is needed to protect public health, the certification is treated as granted. A certified medical gas is treated as having an approved drug application for specific uses: oxygen for treating or preventing hypoxemia or hypoxia; nitrogen for hypoxic challenge testing; nitrous oxide for pain relief; carbon dioxide for ECMO or respiratory stimulation; helium for upper airway obstruction or high airway resistance; medical air to reduce hyperoxia risk; carbon monoxide for lung diffusion testing; and any other uses the Secretary allows unless a new-drug exclusivity period under clause (iii) or (iv) of section 355(c)(3)(E), clause (iii) or (iv) of section 355(j)(5)(F), or section 360cc, or its extension under section 355a, has not expired. The final container label must include the information required by section 353(b)(4), a warning the Secretary sets, and storage and handling directions to meet sections 353(b)(4) and 352(f). No exclusivity under sections 355(c), 355(j), or 360cc, or an extension under 355a, can be based on this treated approval. The Secretary may withdraw or suspend drug approvals and may revoke a certification for material omission or falsification. Designated medical gases are subject to the prescription rule in section 353(b)(1) unless the Secretary removes that requirement under section 353(b)(3), the gas is approved without a prescription under section 355 or 360b, or the use is allowed under other emergency rules. Oxygen may be supplied without a prescription for depressurization or other environmental oxygen deficiency and for emergency resuscitation by trained personnel; such oxygen must be labeled as for emergency use only and say a prescription is required for other medical uses to meet section 353(b)(4).

(B)The name and address of the sponsor.
(C)The name and address of the facility or facilities where the medical gas is or will be manufactured.
(D)Any other information deemed appropriate by the Secretary to determine whether the medical gas is a designated medical gas.

(A)the medical gas subject to the certification is not a designated medical gas;
(B)the request does not contain the information required under paragraph (1) or otherwise lacks sufficient information to permit the Secretary to determine that the medical gas is a designated medical gas; or
(C)denying the request is necessary to protect the public health.
(3)(A)(i)A designated medical gas for which a certification is granted under paragraph (2) is deemed, alone or in combination, as medically appropriate, with another designated medical gas or gases for which a certification or certifications have been granted, to have in effect an approved application under section 355 or 360b of this title, subject to all applicable postapproval requirements, for the following indications for use:
(I)In the case of oxygen, the treatment or prevention of hypoxemia or hypoxia.
(II)In the case of nitrogen, use in hypoxic challenge testing.
(III)In the case of nitrous oxide, analgesia.
(IV)In the case of carbon dioxide, use in extracorporeal membrane oxygenation therapy or respiratory stimulation.
(V)In the case of helium, the treatment of upper airway obstruction or increased airway resistance.
(VI)In the case of medical air, to reduce the risk of hyperoxia.
(VII)In the case of carbon monoxide, use in lung diffusion testing.
(VIII)Any other indication for use for a designated medical gas or combination of designated medical gases deemed appropriate by the Secretary, unless any period of exclusivity for a new drug under clause (iii) or (iv) of section 355(c)(3)(E) of this title, clause (iii) or (iv) of section 355(j)(5)(F) of this title, or section 360cc of this title, or the extension of any such period under section 355a of this title, applicable to such indication for use for such gas or combination of gases has not expired.
(ii)The requirements of section 353(b)(4) and 352(f) of this title are deemed to have been met for a designated medical gas if the labeling on the final use container for such medical gas bears—
(I)the information required by section 353(b)(4) of this title;
(II)a warning statement concerning the use of the medical gas as determined by the Secretary by regulation; and
(III)appropriate directions and warnings concerning storage and handling.
(B)(i)No designated medical gas deemed under subparagraph (A)(i) to have in effect an approved application is eligible for any period of exclusivity for a new drug under section 355(c), 355(j), or 360cc of this title, or the extension of any such period under section 355a of this title, on the basis of such deemed approval.
(ii)No period of exclusivity under section 355(c), 355(j), or section 360cc of this title, or the extension of any such period under section 355a of this title, with respect to an application for a drug product, shall prohibit, limit, or otherwise affect the submission, grant, or effect of a certification under this section, except as provided in subsection (a)(3)(A)(i)(VIII) and section 360ddd(1)(H) of this title.
(4)(A)Nothing in this part limits the Secretary’s authority to withdraw or suspend approval of a drug product, including a designated medical gas deemed under this section to have in effect an approved application under section 355 of this title or section 360b of this title.
(B)The Secretary may revoke the grant of a certification under paragraph (2) if the Secretary determines that the request for certification contains any material omission or falsification.
(b)(1)A designated medical gas shall be subject to the requirements of section 353(b)(1) of this title unless the Secretary exercises the authority provided in section 353(b)(3) of this title to remove such medical gas from the requirements of section 353(b)(1) of this title, the gas is approved for use without a prescription pursuant to an application under section 355 or 360b of this title, or the use in question is authorized pursuant to another provision of this chapter relating to use of medical products in emergencies.
