WebbMechanisms: Most drugs act by altering the various body control systems, which may be receptors, enzymes or ion channels. These various mechanisms include: 1. Physical mechanisms 2. Chemical mechanisms 3. Drug- receptor interactions 4. Drug- enzyme interactions 5. Drug- channel interactions 6. Miscellaneous mechanisms tweet Webbtumefaciens-induced potato disc tumor assay was an effective indicator of antitumor activity regardless of the mechanism of drug action. Thus, this assay would be …
WebbThe receptor occupation theory of drug action equates drug effect to receptor occupancy. The intensity of drug effect is proportional to the number of receptors that are occupied by drug and the maximum effect occurs when all receptors are occupied by drug. Webbdrug therapy. … throughout the body is called pharmacokinetics, which includes the absorption, distribution, localization in tissues, biotransformation, and excretion of drugs.
