Answer:
In addition to the drug-receptor interaction, drugs can affect cells in several other ways.
Step-by-step explanation:
One mechanism is through the alteration of ion channels, which can change the flow of ions into and out of cells. This can affect the electrical properties of cells and can lead to changes in cell signaling and function.
Another mechanism is through the modulation of enzymes, which can alter the rates of metabolic reactions in cells. This can affect the production of cellular products and can lead to changes in cellular function.
Drugs can also affect cells by altering the physical properties of cell membranes, which can affect the movement of molecules in and out of cells. This can lead to changes in cell signaling and function.
Finally, drugs can affect cells by binding to DNA or RNA, which can alter gene expression and protein production. This can lead to changes in cellular function and can affect the development and progression of diseases.
