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

269
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 Regulation01:25

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...

科学分野:

  • 神経科学;生体医工学;老年医学

背景:

  • アルツハイマー病（AD）の病態生理には、タンパク質病変、酸化ストレス、神経炎症、脳腸相関の機能不全が関与している。;光線力学療法（PBM）は、ADに対する非侵襲的治療として低レベル光療法を使用する。;PBMの前臨床研究は、酸化ストレスと炎症を軽減し、神経新生を促進することを示唆している。

研究 の 目的:

  • ADに対するPBM療法の現在の臨床的エビデンスを批判的に評価すること。;AD治療のためのPBMの治療可能性と実現可能性を評価すること。;ADの併用療法戦略におけるPBMの役割を探求すること。

主な方法:

  • 2017年以降に出版された8件の臨床研究の系統的レビュー。;二重盲検、単盲検、およびオープンランダム化比較試験（RCT）が含まれた。;研究には、AD、認知症、または軽度認知障害（MCI）の患者が関与した。

主要な成果:

  • PBMは、ADおよび関連認知症に対して一貫して安全であることが実証されている。;予備的なエビデンスは、PBM療法による認知機能の改善の可能性を示唆している。;サンプルサイズが小さく、方法論的な異質性があるため、エビデンスは限定的であり、さらなる研究が必要である。

結論:

  • PBM療法は、安全で非侵襲的なAD治療として大きな可能性を秘めている。;広範な臨床応用には、厳格な有効性の検証と標準化されたプロトコルが必要である。;将来の質の高い研究は、PBMをADの主要な治療選択肢として確立するために不可欠である。
