Glossary and DefinitionsDistributionDrug distribution is the process by which a drug reversibly leaves the bloodstream and enters the interstitium (extracellular fluid) and/or the cells of thetissues. The pitching of a drug from the plasma to the interstitium primarilydepends on blood flow, capillary vessel permeability, the degree of binding of the drugto plasma and tissue proteins, and the relative hydrophobicity of the drug.ExcipientVehicle. A more or less inert substance added in a prescription as a diluent orvehicle or to give clear or consistency when the remedy is given in pill formsimple syrup, aromatic powder, honey, and various elixirs atomic number 18 examples. mousseA colloidal state in which the molecules of the dispersed phase form a three-dimensional twist in the continuous phase to capture a semisolid materialsuch as a jelly. For example, a warm, dilute(2 percent) solution of gelatin(aprotein mixture) forms, on cooling, a stiff gel in which the molecules of thec ontinuous phase are trapped in the holes of a "brush-heap" like structure ofthe gelatin. Administered orally.Microphotographic emulsionMicroemulsions are thermodynamically stable, optically transparent, isotropicmixtures of a biphasic oil-water system stabilized with surfactants. Thediameter of droplets in a microemulsion may be in the diverge of 100 A to 1000 A.Microemulsion may be formed impromptu by agitating the oil and water phaseswith carefully selected surfactants. The type of emulsion produced depends uponthe properties of the oil and surfactants utilized.OintmentSemisolid preparations intended for topical application. Most ointments areapplied to the skin, although they may also be administered ophtalmically,nasally, aurally, rectally, or vaginally. With a few exceptions, ointments areapplied for their local effect on the tissue membrane rather than for systematiceffects.Professional skillsBody of systematic scientific knowledge, manual dexterity and deftness,p roficiency, resulting from training, practice and experience particular of anindividual who has completed the musket ball education and examination required formembership in a profession. urineA clear, colorless, odorless and tasteless liquid, H2O that is essential for
