Force Classification01:22

Force Classification

2.5K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Classification of Neurotransmitters01:30

Classification of Neurotransmitters

5.4K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Classification of Leukocytes01:30

Classification of Leukocytes

6.1K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Classification of Illness01:17

Classification of Illness

8.9K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Classification of Bones01:18

Classification of Bones

10.1K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Seizures: Classification01:13

Seizures: Classification

1.7K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Area of Science:

  • Pharmaceutical Sciences
  • Drug Development
  • Biopharmaceutics

Background:

  • The Developability Classification System (DCS) was introduced in 2010 to bridge the gap between regulatory guidance and early-stage oral drug candidate assessment.
  • The original DCS utilized intestinal solubility, permeability, and particle size to predict oral absorption limitations.
  • There was a need for a more refined system to handle complex drug properties and improve prediction accuracy.

Purpose of the Study:

  • To propose a refined Developability Classification System (rDCS) for enhanced early-stage evaluation of oral drug candidates.
  • To stratify investigations into standard and customized approaches based on drug properties.
  • To provide a pragmatic framework for comparing drug candidates and formulation strategies.

Main Methods:

  • The rDCS employs standard investigations for solubility and permeability, comparing results against specific datasets for fasted state human intestinal fluid solubility and human effective jejunal permeability.
  • Customized investigations are implemented for candidates with supersaturation/precipitation potential (e.g., weak bases, salts of weak acids).
  • The system assesses the balance between dissolution and permeation-limited absorption and offers facile visualization tools.

Main Results:

  • The rDCS provides a structured approach to evaluating drug developability for oral delivery.
  • It allows for targeted investigations based on specific drug characteristics, such as weak bases and weak acid salts.
  • The system facilitates a clear comparison of different drug candidates and formulation strategies through visualized results.

Conclusions:

  • The refined Developability Classification System (rDCS) offers a more comprehensive and adaptable framework for assessing oral drug candidate suitability.
  • It improves the prediction of absorption-limiting factors by incorporating customized investigations and clear data visualization.
  • The rDCS is expected to aid in more efficient and informed decision-making during the drug development process.
