Hello everyone, I have a question related to the distribution of drugs in the body. How exactly does the substance understand what to do? Or is the whole body under the influence of the drug?
Hello! You understand correctly that the drug is distributed throughout all organs and tissues of the body. But some organs have a greater affinity for it and accumulate this medicine more. For example, liposomal drugs usually accumulate in the liver and lungs, iron supplements go to the liver and spleen more, iodine accumulates more in the thyroid gland, etc.
The interaction of drugs on cells is carried out, including through cell receptors. Each fabric has its own, this determines the specificity of the work
