Drug Discovery: Overview01:26

Drug Discovery: Overview

7.9K
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...

Clinical Trials: Overview01:11

Clinical Trials: Overview

3.0K
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 Regulation01:25

Drug Regulation

1.4K
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...

Preclinical Development: Overview01:28

Preclinical Development: Overview

4.4K
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...

Drug Administration and Therapy Phases: Overview01:26

Drug Administration and Therapy Phases: Overview

471
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...

Prescription, Nonprescription and Orphan Drugs

734
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

Area of Science:

  • Regulatory Science
  • Pharmaceutical Policy
  • Drug Development

Background:

  • The Food and Drug Administration (FDA) provides several expedited programs to accelerate drug development and approval.
  • Incentive programs like Orphan Drug Designation (ODD), Qualified Infectious Disease Product Designation (QIDP), and Rare Pediatric Disease Designation (RPDD) encourage development of drugs with limited commercial viability.

Purpose of the Study:

  • To analyze the utilization of FDA expedited programs in recent drug approvals.
  • To discuss potential future enhancements for drug development and regulatory processes.

Main Methods:

  • Review of recent FDA drug approvals.
  • Analysis of the application and impact of various expedited pathways.
  • Discussion of regulatory and sponsor strategies.

Main Results:

  • Expedited programs have been instrumental in bringing innovative drugs to market since 2010.
  • These pathways effectively incentivize drug sponsors to develop needed therapies.
  • Programs address both urgent medical needs and areas with lower economic incentives.

Conclusions:

  • FDA expedited programs are largely effective in facilitating timely access to innovative medicines.
  • Continued collaboration between sponsors and regulatory agencies can further optimize drug development timelines.
  • Future strategies should focus on maximizing the efficiency of these pathways for patient benefit.
