Recent Journal Articles (2015) on Drug Dissolution: A Comprehensive Overview
Drug dissolution, the process by which a solid drug substance dissolves in a liquid medium, plays a critical role in oral drug bioavailability. Understanding the factors affecting dissolution is crucial for pharmaceutical scientists to design effective and safe drug delivery systems. This article provides a comprehensive overview of key aspects of drug dissolution, focusing on recent journal articles published in 2015. While I can't provide specific article titles or direct links (as per your instructions), I will highlight major themes and research directions explored in the literature of that year.
Key Factors Influencing Drug Dissolution
Research in 2015 continued to explore the complex interplay of factors affecting drug dissolution. These include:
-
Physicochemical Properties of the Drug: Articles likely examined the impact of drug solubility, particle size, crystal habit, and polymorphism on dissolution rate. Smaller particle size, for example, generally leads to increased surface area, thus enhancing dissolution. Polymorphic forms, having different crystal structures, often exhibit vastly different dissolution profiles.
-
Formulation Factors: The role of excipients, including disintegrants, surfactants, and polymers, in modifying dissolution was a significant focus. Studies likely investigated how different excipient combinations influenced drug release and bioavailability. Solid dispersion techniques, aiming to improve the dissolution of poorly soluble drugs, were undoubtedly explored extensively.
-
In-Vitro Dissolution Testing: Advances in in-vitro dissolution testing methodologies were likely published. This included improvements in apparatus design, media selection, and analytical techniques for accurate and reproducible dissolution testing. Validation of dissolution methods remained a crucial topic.
-
In-Vivo Correlation: Significant efforts were directed towards establishing a robust correlation between in-vitro dissolution testing and in-vivo drug absorption. This correlation is paramount for predicting drug bioavailability and optimizing dosage forms.
Emerging Trends in 2015 Drug Dissolution Research
2015 likely saw an increase in research on the following areas:
-
Dissolution Enhancement of Poorly Soluble Drugs: This remains a major challenge in drug development. Research likely focused on novel strategies to improve the dissolution rate of poorly soluble drugs, such as nanotechnology, solid dispersions, and co-solvency approaches.
-
Impact of Food on Drug Dissolution: The influence of food on the dissolution and absorption of oral medications was another area of active research. Studies likely investigated the effect of different food types and their components on drug dissolution in the gastrointestinal tract.
-
Dissolution Testing for Different Dosage Forms: The complexity of dissolution testing varies widely depending on the drug dosage form. Research in 2015 likely addressed specific challenges in dissolution testing for different forms, such as tablets, capsules, and controlled-release formulations.
Practical Applications and Future Directions
Understanding drug dissolution is crucial for:
-
Optimizing drug bioavailability: Improved dissolution leads to better absorption and efficacy.
-
Developing effective drug delivery systems: New formulations are designed to overcome dissolution limitations.
-
Ensuring drug product quality and consistency: Robust dissolution testing guarantees product quality and reproducibility.
Future research in drug dissolution will likely focus on:
-
Predictive modeling: Developing more accurate models to predict drug dissolution behavior.
-
Advanced characterization techniques: Employing innovative techniques to characterize the solid state of drugs and their interactions with excipients.
-
Personalized medicine: Tailoring drug formulations to individual patient characteristics.
