FPPS Faculty Spotlight: Dr. Aaron Opoku Antwi – Bridging Nature and Medicine

Dr. Aaron Opoku Antwi is a Senior Lecturer and Researcher at the Department of Pharmacology at Kwame Nkrumah University of Science and Technology (KNUST) in Ghana. His journey into the world of pharmacology was not just a career choice but a calling shaped by passion, curiosity, and an unwavering desire to make a difference in healthcare.
It all began at St. Peter’s Boys Secondary School in Nkwatia Kwahu, where his love for science took root. A pivotal moment in his academic life came when he applied for and gained admission into the Bachelor of Pharmacy programme at KNUST—a choice that set the stage for a career in pharmacological research.
After earning his Bachelor of Pharmacy (BPharm) degree and being inducted as a pharmacist, Dr. Antwi embarked on a path that deviated from the conventional. Unlike many of his peers who pursued careers in hospitals or the pharmaceutical industry, he discovered his true passion in academia during his National Service as a Teaching Assistant at the University of Cape Coast (UCC). Realizing that his greatest strength lay in mentorship, research, and discovery, he took on the challenge of further education, completing both his MPhil and PhD in Pharmacology at KNUST in six years. In 2020, he officially joined the Faculty of Pharmacy and Pharmaceutical Sciences at KNUST, where he has been inspiring young scientists and conducting cutting-edge research for the past five years. His dedication and contributions have recently earned him a promotion to Senior Lecturer—a testament to his impact in the field.
Breaking New Ground: Dr. Antwi’s Research in Phytomedicine and Immunopharmacology
At the heart of Dr. Antwi’s work is a commitment to uncovering the medicinal potential of nature. His research focuses on the pharmacology and toxicology of natural products, exploring how medicinal plants and plant-derived compounds can be harnessed to create safer and more effective treatments. With over 20 research publications, he has built a reputation as a leader in immunopharmacology, utilizing both in vivo and in vitro techniques to assess the efficacy and safety of traditional herbal medicine.
He is currently leading a research project funded by the KNUST Research Fund to document ethnobotanical remedies for asthma in the Kumasi Metropolis. This initiative bridges traditional knowledge with modern pharmacological techniques, paving the way for novel drug discovery efforts. His team is actively working on compound isolation and characterization, hoping to uncover groundbreaking solutions for respiratory conditions.
One of Dr. Antwi’s most recent and impactful studies was published in Scientific African. His research investigates Aurantio-obtusin, a natural anthraquinone compound, for its potential to treat allergic rhinitis—a condition that affects millions worldwide.
His study found that Aurantio-obtusin significantly reduces allergic symptoms, such as:
- Sneezing and runny nose
- swelling and irritation inside the nose
- Higher levels of substances that cause inflammation (like TNF-α, IL-4, IL-6)
- Histamine release, which causes allergies
In a study using mice with allergy-induced stuffy nose (allergic rhinitis), Aaron and his team of researchers found that Aurantio-obtusin works by gradually suppressing allergic reactions as the dose increases, reducing the number of certain white blood cells (eosinophils) that cause inflammation, and lowering inflammation markers in the body. These show that the compound can effectively help in managing allergies.
Why does this matter?
Traditional treatments for allergic rhinitis—antihistamines, corticosteroids, and mast cell stabilizers—often come with side effects like drowsiness, dry mouth, and potential dependency issues. Dr. Antwi’s findings suggest that plant-based compounds like Aurantio-obtusin could provide a natural alternative without these side effects, changing the way allergies are treated.
This research not only highlights his skills in natural pharmacology and drug discovery but also places him at the forefront of combining plant-based medicines with modern science globally.
A Scientist, a Mentor, and a Community Builder
Dr. Antwi is more than just a researcher—he is a mentor, an educator, and a role model. At KNUST, he is deeply involved in training the next generation of scientists and pharmacists, guiding them toward innovative solutions in pharmacology. His passion for collaboration is evident in his membership in leading pharmaceutical and scientific organizations, including the American Society for Pharmacology and Experimental Therapeutics (ASPET) and the Pharmaceutical Society of Ghana. Through these platforms, he actively engages in global scientific discussions, ensuring that African-led research contributes to the world’s pharmaceutical advancements.
Beyond Science: The Man Behind the Lab Coat
Despite his demanding career, Dr. Antwi is a devoted family man, happily married with four children—two daughters and twin boys. Balancing academia with family life is no small feat, but he does so with grace, making time for his loved ones even in the midst of research deadlines. When he does get a rare moment to unwind, you’ll likely find him:
🎶 Listening to classic gospel music – A soul-refreshing escape from the rigors of academia.
⚽ Watching Arsenal FC – A true fan through thick and thin, embracing both the triumphs and heartbreaks that come with supporting the club.
