Introduction The ocular drug development landscape is rapidly expanding, encompassing small molecules, biologics, gene and cell therapies, and novel drug delivery platforms. Increasingly, ocular delivery routes such as intravitreal, subconjunctival, and periocular administration are being used to target the posterior segment of the eye and support the development of injectable and implantable prolonged-action dosage forms….

Drug development is often portrayed as a story of discovery and innovation, but behind every promising molecule lies a critical question: what is the first safe dose in humans? Getting this wrong can derail years of research, cost millions, and, more importantly, put human lives at risk. Toxicology data forms the backbone of this decision,…

The pharmaceutical landscape has witnessed growing interest in deuterated drugs, a class of therapeutics developed by replacing specific hydrogen atoms in drug molecules with deuterium, a naturally occurring, stable, and non-radioactive isotope of hydrogen. While chemically similar to hydrogen, deuterium possesses an additional neutron, resulting in stronger carbon–deuterium bonds and measurable effects on drug metabolism…

Introduction In modern toxicology and pharmaceutical science, understanding how chemicals and drugs interact with the human body goes far beyond metabolism alone. A less visible, but equally critical, ayer of biological control lies in membrane transporters. These specialized proteins act as molecular gatekeepers, regulating the movement of endogenous substances, xenobiotics, and pharmaceuticals across biological membranes….

Introduction The classical understanding of toxicology has long relied on the dose–response relationship to predict adverse effects. However, modern research increasingly shows that chemical exposure does not always result in immediate or visible tissue damage. Instead, many substances subtly disrupt cellular functions, weakening biological defenses and increasing vulnerability to secondary insults. These effects are particularly…

A structural shift in chemical governance is underway For decades, per- and polyfluoroalkyl substances (PFAS) have been integral to modern manufacturing. Their resistance to heat, chemical stress, and degradation enabled their widespread use in electronics, industrial equipment, textiles, coatings, membranes, seals, and numerous advanced applications. That period of regulatory tolerance is rapidly closing. Across Europe,…

Why Chemical Risk Assessment Matters Every chemical, whether used in medicines, cosmetics, food, or industrial processes, carries some degree of risk. The purpose of chemical risk assessment is not to eliminate risk entirely, but to understand, quantify, and manage it effectively. In public health, environmental protection, and regulatory decision-making, risk assessment serves as a critical…
