Glossary and DefinitionsDistributionDrug distribution is the process by which a drug reversibly leaves the logical argumentstream and enters the interstitium (extracellular fluid) and/or the cells of thetissue papers. The delivery of a drug from the plasma to the interstitium primarilydepends on blood flow, capillary 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 orfomite or to give form or consistency when the remedy is given in pill formsimple syrup, aromatic powder, honey, and various elixirs argon examples. gelA colloidal state in which the molecules of the dispersed phase form a three-dimensional structure in the continuous phase to produce 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 thecontinu ous phase are trapped in the holes of a "brush-heap" like structure ofthe gelatin. Administered orally.MicroemulsionMicroemulsions are thermodynamically stable, optically transparent, isotropicmixtures of a biphasic oil- pissing system stabilized with surfactants. Thediameter of droplets in a microemulsion may be in the range of 100 A to 1000 A.Microemulsion may be formed spontaneously 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,proficiency, resulti ng from training, practice and experience particular of anindividual who has completed the formal education and examination required formembership in a profession. peeingA clear, colorless, odorless and tasteless liquid, H2O that is essential for
