The pharmaceutical industry is constantly evolving, driven by innovations in research and development. This continuous push for advancement extends to the equipment used in preclinical and clinical trials, as researchers seek tools that are more accurate, efficient, and reliable. Here, we delve into the latest trends in four key pieces of equipment used in various stages of drug development: plethysmometers, radial arm mazes, watermazes, and FBD fluid bed dryers.

Plethysmometers:

Measuring body composition is crucial for understanding the effects of drugs on metabolism, energy expenditure, and overall health. Plethysmometers, which utilize air displacement or water displacement techniques, have long been the go-to tool for this purpose. However, recent trends highlight advancements in:

Dual-energy X-ray absorptiometry (DXA) plethysmometers: These combine the traditional air displacement method with DXA scanning, providing highly accurate and precise measurements of fat, lean mass, and bone mineral density simultaneously.

Whole-body plethysmometers: These chambers accommodate larger animals, enabling studies on species like pigs and sheep, which are closer to humans in physiology than rodents.

High-throughput plethysmometers: These automated systems allow for rapid measurement of multiple animals, improving efficiency and throughput in preclinical studies.

Radial Arm Mazes:

Assessing cognitive function and learning abilities is essential for evaluating drugs targeting neurological disorders. Radial arm mazes (RAMs) are popular tools for this purpose, and recent trends encompass:

Touchscreen-based RAMs: These eliminate the need for physical barriers and reward mechanisms, simplifying setup and operation while offering flexibility in task design.

Virtual reality (VR) RAMs: Immersive VR environments provide more complex and natural stimuli, potentially leading to more robust and ecologically relevant behavioral assessments.

Automated RAMs: These systems track animal movements and choices electronically, reducing human error and increasing data accuracy.

Watermazes:

Spatial learning and memory are critical cognitive functions often impaired in neurodegenerative diseases like Alzheimer's. Watermazes, where animals navigate to a hidden platform submerged in water, are widely used to evaluate these functions. Recent trends include:

Morris watermaze variations: Modifications like the probe test, radial watermaze, and Barnes maze offer additional insights into specific aspects of spatial learning and memory.

Video tracking systems: Automated tracking eliminates manual scoring, improving objectivity and data consistency.

Chemogenetic watermazes: Combining watermaze testing with chemogenetic manipulation of specific brain circuits allows researchers to pinpoint the neural substrates of spatial learning and memory.

FBD Fluid Bed Dryers:

Drying pharmaceutical products is a crucial step in manufacturing, and fluid bed dryers (FBDs) offer several advantages over traditional methods. Recent trends in FBDs focus on:

Continuous processing: This approach improves efficiency and scalability, particularly for high-volume production.

Advanced process control: Real-time monitoring and adjustment of parameters like temperature, airflow, and product moisture content ensure consistent and high-quality drying.

Integration with other unit operations: Seamless integration with granulation, blending, and coating equipment streamlines production processes.

Energy efficiency: Newer FBD designs incorporate features like improved insulation and heat recovery systems to reduce energy consumption.
