Preclinical Development: Overview01:28

Preclinical Development: Overview

5.7K
Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

Clinical Trials: Overview01:11

Clinical Trials: Overview

4.5K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Drug Discovery: Overview01:26

Drug Discovery: Overview

10.9K
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Drug Administration and Therapy Phases: Overview

1.1K
Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
The pharmacokinetic phase...

In Vitro Drug Release Testing: Overview, Development and Validation

279
In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Drug Regulation

2.7K
Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Resumen
Este resumen es generado por máquina.

Una nueva plataforma bioinformática, Integrative Pathway Activity Analysis (IPAA), predice con precisión los mecanismos de la enfermedad de Alzheimer (EA) relevantes para los humanos. La focalización de la vía p38 MAPK-MK2 en modelos redujo la patología de la EA, ofreciendo una estrategia terapéutica prometedora.

Área de la Ciencia:

  • Neurociencia; Bioinformática; Farmacología

Sus antecedentes:

  • Los tratamientos para la enfermedad de Alzheimer (EA) que tuvieron éxito en modelos preclínicos a menudo fallan en ensayos humanos.; Se necesita un enfoque sistemático para validar mecanismos diana preclínicos para la relevancia terapéutica humana.; Cerrar la brecha preclínica-clínica es crucial para el desarrollo eficaz de fármacos para la EA.

Objetivo del estudio:

  • Desarrollar y validar una plataforma bioinformática (IPAA) para evaluar la relevancia de modelos preclínicos para la EA humana.; Identificar desregulaciones de vías de EA conservadas entre cerebros humanos y modelos preclínicos.; Evaluar el potencial terapéutico de la focalización de vías identificadas en modelos de EA.
