Although the device works in theory, a long road lies between conceptualization to actualization. Because this product claims to assist patients with injuries by providing a drug to their system, it will first need to undergo pre-clinical, phase I, and phase II trials before proceeding to potentially several phase III and IV clinical trial on humans to establish the appropriate formula and demonstrate its safety and efficacy. Also, according to the FDA, a drug patch is classified as a combination device, and thus its simpler parts, such as the ice bag and elastic bandage, would qualify as Class I devices, while the actual drug-eluting patch would classify as a Class III device, since theoretically, misuse could threaten life.
In order to get the drug to market, if first has to undergo pre-clinical trials, which utilize studies on animals as well as on the drug purity and production process. These serve to understand “1) the drug’s safety in doses equivalent to approximated human exposures, 2) pharmacodynamics (ie, mechanisms of action, and the relationship between drug levels and cl...
Pharmaceuticals have examined and found to ”work by changing the biological functions of the target cells in the body through chemical agents“ (Doweiko, 2015, p. 16). ”Many people in the past have thought that drugs that
“Animals of different ages, sexes, developmental stages, and of different health status can all respond differently to experimental treatments. It is no surprise, then, that humans respond differently to administered pharmaceuticals than other animals” (Physicians Committee for Responsible Medicine).Thalidomide being the most well known example was a drug sold between 1957 and 1961 and was marketed towards pregnant women and was said to relieve morning sickness, stress and to help them sleep. The drug was tested thoroughly on mice, with no ill eff...
Mathematical models and computer simulations generate the most unqualified enthusiasm among campaigners. One of their underlying principles is that the biological effects of a chemical will depend on the size, shape, and other characteristics of its molecules, making it possible to predict toxicity without actual testing. The database on which such systems rely will, of course, have come from animal experiments. But once the relation between molecular structure and activity is understood, the toxicity of any new substance can be predicted with a computer instead of measured in a mouse.
Blockbuster drugs are usually a significant therapeutic breakthrough compared to previously available therapies. However greater therapeutic value alone is not enough for cr...

...s little information about the possible benefits of the study or the side effects. The side effects proved to be significant (gastrointestinal complains, headache, and an elevation of alanine aminotransferase), while the benefits were minimal. This situation emphasizes the need for a balanced approach when it comes to drug clinical trials.

Animals have always held a very special place in the hearts of the human race. They are our best friends, our stress relievers, members of our families, and our test subjects for experimentation. For hundreds of years, animals have been used in laboratory settings as a replacement for humans when studying the effects of medical treatments. On average, nearly one hundred million animals are used in clinical trials every year (Ferdowsian). These animals have contributed to hundreds of breakthroughs in the medical field including countless toxicity tests to determine drug toxicity to humans, and exposure to paralyzing anesthetics to create anesthesia used in surgical procedures today. These animals have been vital
The most common way that the pharmaceutical industry uses their power and influence to create lifelong customers is in the manipulation of clinical research. When a pharmaceutical company creates a new drug, it must first get the go ahead from the Foo...
Dosing regimens and drug combinations were selected empirically and this is due to several challenges.[7, 8] First, most protocols utilise drug combinations and each drug has a different mechanism of action. Secondly, dose optimisation has not been established because low-dose protocols aren’t defined by dose-limiting toxicities. Finally, clinically applicable biomarkers of tumour response are yet to be established.[23]
In the past, animals have been subjected to inhumane and often unnecessary tests to determine the lethality of chemical-containing drugs and products. Such experimental procedures have angered animal rights enthusiasts and made many question the usefulness of such testing. Typically, the information received from toxicity tests on animals cannot adequately predict the effects that new drugs and products will have on humans. Thus, the recent progression of in vitro and in silico assays has benefited not only lab rodents, but researchers alike.

Clinical trials containing new drugs are categorized into essential four phases (1). The drug development procedures are usually performed through the all phases over several years (1). The drug will be approved for use in the general population, if it successfully exceeds through the first three phases; I, II, and III. The fourth phase -IV- is called Post marketing Surveillance and/or Post approval studies (2). Postmarketing Surveillance Trial provides the safety surveillance (Pharmacovigilance) (3). phase IV Analytics methods studies may be required by sponsoring companies, when detecting a new drug market or testing the drug interactions with other drugs, and also by regulatory authorities (4). The safety surveillance, which is a very important part of a comprehensive post-marketing program, investigates drugs long term effects in a large number of people (1) (3).
Before medicinal products can be sold or given to patients, they need to have a marketing authorisation. Information about the product is considered before this authorisation is granted to make sure that it is safe and useful and that the quality of the product is adequate. Clinical trials are carried out find out data on the safety and the desired effect of the new products. These trials can be performed using healthy volunteers or patients which depend on the type of product and the stage of which the products development is at (MHRA, About clinical trials for medicinal products, 2011).
