Week 2 Assignment

  1. Why are drugs classified in the categories they are?

Drug classification is essential since related drugs have similar impacts on the human body. Hence, it is easier for healthcare professionals to predict their therapeutic effects in relation to a specific illness. Furthermore, they can determine the side effects, drug-drug interactions, and contraindications. Hence, the classes enhance the safe use of medicine to provide optimal health outcomes.

  1. Give a description of the actions of drugs in each category.

Some common drug categories include analgesics, antibiotics, antihistamines, and antiarrhythmics. Analgesics alter the central nervous system to block pain receptors. Meanwhile, antihistamines affect the endocrine system, reducing inflammation and offset anaphylaxis (Olson, 2010). Antibiotics attack bacteria in the body, killing them and eliminating the disease they cause. Finally, antiarrhythmics regulate the heartbeat, making it steady (Bihari, 2021).

  1. What is chemotherapy, and which diseases are treated this way?

Chemotherapy is the process of administering chemicals to the body to destroy cells that are growing uncontrollably. It is a systemic therapy. Hence it impacts the entire body. Chemotherapy is indicated for cancer treatment. Cancer cells grow and multiply rapidly, making chemotherapy an ideal treatment (Krans, 2021).

  1. Give examples of how contrast media are used to produce an image.

Contrast media are dyes that temporarily change the physical properties of body tissues, making it easier for x-rays to detect specific characteristics, such as inflammation, growths, etc. For instance, one can ingest the media orally, producing a color contrast along the gastrointestinal system. Intravenous and intraarterial injection of contrast media can target a localized area or an entire organ system. Iodine-based compounds and Barium Sulfate are the preferred contrast media for x-rays and CT scans, while Gadolinium is useful in MR tests (RadiologyInfo.org, 2020).

  1. Compare ionic and non-ionic contrast media.

Ionic contrast media have high osmolality, meaning that they can dissolve into charged particles when in solution. Conversely, non-ionic do form ions when they dissolve in the solution. Ionic contrast can react with the body to create adverse effects. However, non-ionic media are non-reactive and safer (Mosler et al., 2021). Non-ionic media are also more expensive than ionic media.
