WebbDrug absorption may be slow and erratic. The volume of injection, osmolality of the solution, lipid solubility and degree of ionization influence absorption. It should not be … WebbOther routes. Inhalation. This route is used for gaseous drugs or those that can be dispersed in an aerosol, and is produces an effect almost as fast as with IV. It provides rapid delivery across the mucous membranes of the respirateory tract. It is used for asthmatic drugs, and anesthetics. Intranasal. Drug administration directly into the nose.

WebbAbsorption rate is slowed by coating drug particles with wax or other water-insoluble material, by embedding the drug in a matrix that releases it slowly during transit through the gastrointestinal tract, or by complexing the drug with ion-exchange resins. The most reliable measure of a drug’s bioavailability is AUC. AUC is directly … Volume of distribution has nothing to do with the actual volume of the body or its … Urine pH, which varies from 4.5 to 8.0, may markedly affect drug reabsorption and … In such cases, called first-order elimination (or kinetics), the metabolism rate of the … Drug-drug interactions arise when drugs compete... read more ).

Absorption (pharmacology) - Wikipedia
WebbIf a drug is to be breathed in and absorbed through the thin mucous membrane that lines the nasal passages, it must be transformed into tiny droplets in air (atomized). Once absorbed, the drug enters the bloodstream. Drugs administered by this route generally work quickly. Some of them irritate the nasal passages. WebbSince many drugs are well absorbed in the upper part of the gastrointestinal tract, such high variability may lead to non-uniform absorption and makes the bioavailability unpredictable. WebbThe slowest route of absorption for a drug is A. intramuscular B. rectal C. oral D. intravenous C Who is responsible for regulating the sale of medicines? A. … home taxable value michigan
