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: Overview01:26

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
  • 臨床試験
  • 公衆衛生

背景:

  • 効果的な治療のためには、アルツハイマー病の二次予防試験において代表的なサンプルを募集することが不可欠である。
  • 過去の研究では、「研究パートナー」の要件が、過少代表となっている人種・民族グループの募集に不均衡な影響を与える可能性があることが示されている。

研究 の 目的:

  • 二次予防試験における募集意図に対する研究パートナー要件の影響を評価する。
  • 参加および研究パートナー募集意図における人種・民族間の格差を調査する。

主な方法:

  • 黒人参加者をオーバーサンプリングした、65歳以上の米国成人を対象とした全国調査を実施した。
  • 参加者は、仮想的な試験に参加する意図と、研究パートナーとなるよう依頼する意図を示した。
  • 募集意図と研究パートナーの意図を分析するために、記述統計と差分計算を使用した。

主要な成果:

  • 回答者のうち、HEALTHY MINDスタディへの参加意図は全体的に低かった（24%）。
  • 参加意図のある回答者のうち、研究パートナーを依頼する意図は中程度であった（平均スコア3.45）。
  • 黒人回答者と白人回答者の間で、参加意図または研究パートナーを依頼する意図に有意な差は見られなかった。

結論:

  • 研究パートナー要件は、二次予防試験における募集の障壁となるようである。
  • 黒人高齢者の過少代表は、参加意図または研究パートナーの意図の低さでは説明されない。
  • 厳格な適格基準や構造的な障壁など、他の要因が代表性の欠如に寄与している可能性が高い。
