On entering the body, drugs are treated as if they are toxic substances, which need to be detoxified, if a mechanism exists, and eliminated as soon as possible.

Tyrosine kinase then activates cellular enzymes, which in turn stimulate transcription of particular genes. This brings about the cellular response to the original hormone, for example growth. These are receptors for steroid hormones and thyroid hormone.
