- Pharmacodynamics ()
Pharmacodynamics in its simplest form asks, “How do drugs do what they do?” Drugs cannot make the body do anything that the body doesn’t normally do. All they do is change the rate of pre-existing physiological processes. The rate of physiological processes is controlled by the rate of neurotransmission. Drugs can alter physiological function by altering […]
- Pharmacokinetics ()
Pharmacokinetics (PK) is the study of how the body interacts with administered substances for the entire duration of exposure (medications for the sake of this article). This is closely related to but distinctly different from pharmacodynamics, which examines the drug’s effect on the body more closely. The four main parameters generally examined by this field […]

- Insulin ()
Human Insulin and Insulin Analogs are available for insulin replacement therapy. Insulins also are classified by the timing of their action in your body – specifically, how quickly they start to act, when they have a maximal effect and how long they act. Insulin analogs have been developed because human insulins have limitations when injected […]
- Endocrine System Drugs ()

Maintaining appropriate blood glucose levels in patients with hyperglycemia is important for minimizing the risk of acute symptoms, long-term complications, and mortality. There are many physiological causes of hyperglycemia, so multi-drug regimens may be required to control blood glucose levels. Biguanides: metformin Metformin is considered first […]
