Abstract
Various aspects of this disclosure relate to containers, devices, and methods to administer single doses of pharmaceutical agents.
Claims20
A container, comprising (i) a hermetically-sealed chamber, (ii) a composition contained within the hermetically-sealed chamber, and (iii) a thermally-conductive surface in thermal communication with the composition, wherein:
- the composition comprises 0.01 to 500 micromoles of a pharmaceutical agent;
- the pharmaceutical agent has a boiling point between 26 and 260 degrees Celsius;
- and
- the thermally-conductive surface has a thermal conductivity greater than 2 watts per meter-Kelvin (W·m−1·K−1).
1 more element
A device, comprising a heating compartment and a heating element, wherein:
- the heating compartment is configured to receive a container that comprises (i) a hermetically-sealed chamber, (ii) a composition that is contained within the hermetically-sealed chamber and that comprises a pharmaceutical agent, and (iii) a thermally-conductive surface in thermal communication with the composition;
- and
- the heating element is configured to be in thermal communication with the thermally-conductive surface after the heating compartment receives the container such that the heating element is operable to (i) heat the thermally-conductive surface and (ii) heat the composition to (i) vaporize at least a portion of the pharmaceutical agent and (ii) produce a vaporized pharmaceutical agent.
A method to prepare a vaporized pharmaceutical agent, comprising:
- providing a container that comprises (i) a hermetically-sealed chamber, (ii) a composition that is contained within the hermetically-sealed chamber and that comprises a pharmaceutical agent, and (iii) a thermally-conductive surface in thermal communication with the composition;
- heating the thermally-conductive surface to heat the composition and to vaporize at least a portion of the pharmaceutical agent to produce a gas phase composition comprising a vaporized pharmaceutical agent;
- connecting the hermetically-sealed chamber of the container to an administration path to convert the hermetically-sealed chamber into an unsealed chamber such that the gas phase composition is in fluid communication with the administration path;
- and
- directing the gas phase composition out of the unsealed chamber and into the administration path.
