  • Oral Product

    A pharmaceutical product meant to be introduced through the mouth in the form of a tablet, capsule, or suspension.
  • Oral Solid Dosage Drug

    Formulated in a solid or powder form for patient to ingest orally.
  • Orally Disintegrating Tablets (ODT)

    (CDER) A solid dosage form containing medicinal substances, which disintegrates rapidly, usually within a matter of seconds, when placed upon the tongue. FDA recommends that ODTs be considered solid oral preparations that disintegrate rapidly in the oral cavity, with an in vitro disintegration time of approximately 30 seconds or less, when based on the USP disintegration test method or alternative.
  • Orally Disintegrating Tablets (ODT)

    Generally, a solid-dosage form that disintegrates and dissolves in the mouth (either on or beneath the tongue or in the buccal cavity) without water within 60 seconds or less.
  • Orange Peel

    An Appearance of a pebbly surface.
  • Orbital Welding

    Automatic or machine welding of tubes or pipe in-place with the electrode rotating (or orbiting) around the work. Orbital welding can be done with the addition of filler material or as a fusion process without the addition of filler.
  • ORD

  • Organic Evolution

    The process by which changes in the genetic composition of populations of organisms occur in response to environmental changes.
  • Organic Peroxide

    An organic compound that contains the bivalent -0-0- structure and which may be considered to be a structural derivative of hydrogen peroxide where on or both of the hydrogen atoms have been replaced by an organic radical. Organic peroxides can present an explosion hazard (detonation or deflagration) or they can be shock sensitive. They can also decompose into various unstable compounds over an extended period.
  • Organics

    Short for organic chemicals; those compounds that contain carbon to hydrogen bonds and are not carbonate related.
  • Organism

    An individual living system, such as animal, plant or micro-organism, that is capable of reproduction, growth and maintenance.
