Drug Nomenclature01:17

Drug Nomenclature

2.3K
During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

Drug Discovery: Overview01:26

Drug Discovery: Overview

8.8K
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 Dependence01:17

Drug Dependence

1.2K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Pharmacovigilance01:19

Pharmacovigilance

1.0K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Drug Elimination: Non-Renal Routes

2.5K
The liver plays a pivotal role in eliminating drugs and their metabolites, primarily through a process known as biliary excretion. This process involves the hepatocytes, the primary cells in the liver that generate bile. A range of transporters actively expels polar drugs or hydrophilic drug metabolites into the bile, which transports the drugs and metabolites into the small intestine. From here, they are eventually expelled from the body through feces. In some instances, the original drug or a...

Drug Regulation01:25

Drug Regulation

1.9K
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...

Area of Science:

  • Computational linguistics
  • Public Health Informatics
  • Machine Learning

Background:

  • Generic Named Entity Recognition (NER) tools struggle with domain-specific entities like drug use.
  • Accurate entity recognition in public health is crucial for real-world applications.
  • Training specialized NER models requires extensive, costly labeled data.

Purpose of the Study:

  • To develop a more efficient method for domain-specific NER, focusing on drug use.
  • To reduce the human effort and time needed for training specialized NER models.
  • To improve the granular recognition of entities within public health reports.

Main Methods:

  • Utilized distant supervision with a domain-specific ontology to minimize manual labeling.
  • Incorporated external, domain-specific knowledge (e.g., drug use) into NER model training.
  • Applied the method to identify drug use entities and trends in government epidemiology reports.

Main Results:

  • Achieved an 8% improvement in F1-score for recognizing drug use-related entities.
  • Demonstrated the effectiveness of distant supervision in domain-specific NER.
  • Successfully captured entities and trends related to drug use from unstructured reports.

Conclusions:

  • Distant supervision with domain ontologies is a viable approach for specialized NER.
  • The developed method significantly enhances the identification of critical public health entities.
