Certificate in Drug Discovery and Development - College of Pharmacy

Effective and safe drug treatments rank high among scientific advancements that have changed people’s lives over the past decades. Cures for infectious diseases, as well as treatments for chronic illnesses like cardiovascular illnesses, central nervous system illnesses, diabetes, and incurable cancer, have drastically changed people’s lives. 

But society is still in the infancy of truly effective treatments. The complexity of diseases, hence the reason for necessary treatments, increases drastically with aging populations. Medications are only partially efficient and effective, sometimes can even cause adverse reactions.

Moreover, medication costs start to place a significant burden on a lot of patients. Recent developments in understanding the human genome – all genes combined – have shown a lot of new insights into human illnesses. People often read about groundbreaking findings on the genetic and molecular causes of illnesses. 

Invariably, experts add that these findings surely will lead to groundbreaking novel treatments of untreatable diseases. But we have not seen the flood of new drugs as promised by these profound developments, a direct result of the intricacies of biological systems – human beings in particular. Whereas new details come to light at a blinding speed, our capacity to interpret results, as well as translate these results into effective treatments, are lagging behind. 

Here lie the excitement and promise for undergrads who want to take part in a new stage for medicine. The entire industry relies on the timely development and discovery of new drugs – a growing and outstanding opportunity for new and young scientists.

Drug Discovery 101 - Biotech Primer WEEKLY

Clinical evaluation, pharmacodynamics, and pharmacokinetics

There is a good chance that medications that successfully interact with target proteins in vitro will never reach their intended site in the body since it is not absorbed, removed from the intended tissue, or is rapidly excreted and metabolized. 

Research of these procedures is known as pharmacokinetics – for instance, what our body does to the medication. In contrast, pharmacodynamics centers on what the medication does to our body – especially the magnitude, time-course, and nature of the drug toxicity and effect. These industries combine mathematical modeling with pharmacological and biological sciences. 

Pharmacokinetic/Pharmacodynamic modeling is a common phrase that has a lot of impact on drug treatment because people can strive to predict medicinal response, adverse events, and optimal dosage. Moreover, it has revealed differences among every patient, alerting people to the need to individualize every dosage regimen. Therefore, pharmacokinetic/Pharmacodynamic modeling is a complex part of the drug development courses and germane to new cure approval by the Food and Drug Agency.

Formulation design and delivery systems

Imagine people have a promising medication candidate, but testing in various animals reveals little to no activity at all. One issue may be that chemicals do not even get into the user’s body or fail to reach the action area. Alternatively, an efficient, effective, and safe treatment plan might need brief applications with immediate reversal of effects like anesthesia, pulsatile delivery like some hormone therapies, or drug delivery over a couple of days like birth control. 

In diabetes treatments, one needs to provide insulin at high levels for a certain time period. It is a challenging task for a lot of individuals. Lastly, targeted medicinal delivery to tumors – and not to healthy tissues – is the main goal of chemotherapy for cancer patients.

Three Principles For Revolutionizing Orphan Drug Development

Clinical evaluation, pharmacogenomics, and pharmacogenetics

The first awareness of the genetic difference in a person’s response to unfamiliar chemicals started in the 1930s. It shows that some people cannot taste bitter substances. Over the past decades, this idea has quickly widened to include various responses to medicinal therapy – already alluded to in the previous paragraph. 

The pharmacogenetic field has emerged with detailed information on genetic alteration in drug-metabolizing enzymes – a primary cause of different drug responses. The significance of genetic differences is underlined by the assertion that changes in drug-metabolizing enzymes may have a significant effect on its adverse reaction – a serious health issue and one of the leading causes of death in the country.

Recently, this industry has widened drastically, reflecting the idea that medications interact with different proteins in our body, every one of them potentially subject to various genetic variations. That is why people need to consider a lot of genes that could have an effect on the outcome of diseases and medication response – leading to Pharmacogenomics. The goal is to discover a primary genetic variation in a society that predisposes to illnesses and permit one to choose the right treatment plan.
