Toxicology & Pharmacology

Both toxicology and pharmacology are concerned with the interactions that can be caused by harmful substances and chemicals in the body.

Definition of Toxicology

Toxicology is the science of the harmful or toxic effects of chemicals on living organisms. It is concerned with the amount, type, duration, frequency and route of exposure required to cause an adverse effect.
The aim of toxicology is to assess the safety of chemicals and set guidelines or limits for their safe use.

Tasks of a Toxicologist

The duties of a toxicologist can vary depending on the exact area of work. Some aspects of the job are described below:

  • Risk assessment and Safety Testing: This includes, for example, the study of dose-response relationships and the setting of limits for chemicals.
  • Laboratory Research: Conducting experiments and studies to understand the specific toxic effects and mechanisms of a substance.
  • Environmental Toxicology: This includes assessing the effects of pollutants in air, water and soil on human health.
  • Forensic Toxicology: This includes the analysis of body fluids and tissues to determine the presence of poisons or drugs. It may also involve working with law enforcement agencies and coroners in forensic cases.
  • Regulatory Toxicology: This includes the development of new safety guidelines, regulations and recommendations, often in collaboration with health and environmental authorities.
  • Education and Teaching: Work at colleges or universities in the form of seminars, lectures and training courses.

In the chemical or pharmaceutical industry, for example, a large part of the work involves the (further) development of active substances or the testing of the harmful potential of certain substances. In the food and feed industry, on the other hand, it is a matter of testing additives for possible hazards, and in ecotoxicology it is often a matter of determining harmful substances in the ecosystem.

Definition of Pharmacology

Pharmacology is the science of the interaction of drugs with living organisms, both human and animal. It deals with the mechanisms of action of drugs, the processing of drugs in the body and the effects produced by drugs.
The aim of pharmacology is to develop and use drugs to treat or prevent disease.

Tasks of a Pharmacologist

Specific pharmacology tasks can also vary depending on the company or position. However, there are some typical aspects that pharmacologists often encounter in their work:

  • Research and Development: This includes, for example, the search for new active ingredients for potential new medicines and the study of the mechanisms of action of medicines.
  • Pharmacokinetics and Pharmacodynamics: Pharmacokinetics is the study of how the body absorbs, distributes, metabolises and excretes a drug. Pharmacodynamics is the study of the effects of a drug on the body.
  • Clinical Trials: This involves the design, conduct and monitoring of clinical trials to test the safety and efficacy of medicines.
  • Regulatory Affairs: Pharmacologists work with health authorities and other regulatory agencies in the approval of new medicines.
  • Education and Teaching: This may involve working with medical students, pharmacists and other health professionals to teach them the principles and applications of pharmacology.
  • Interdisciplinary Collaboration: Working with biologists, chemists, toxicologists, pharmacists and other professionals to share and increase knowledge about medicines and their effects.

Requirements for a Career in Toxicology & Pharmacology

There is a specific degree programme for each of these two fields, but there are other ways to enter a career in toxicology or pharmacology, such as studying medicine, biology or chemistry. It is also possible to pursue a career in toxicology or pharmacology through various training programmes.

In addition to the theoretical and practical requirements, certain soft skills and conditions are also important:

  • A high degree of initiative and responsibility
  • A good technical understanding, especially in the use of equipment
  • Excellent and clear communication skills
  • Good eyesight and sense of smell

Specific requirements depend on the exact job description, but the above are generally important when working in toxicology and pharmacology.
