First Pass Effect01:12

First Pass Effect

5.6K
Presystemic elimination, or the first-pass effect, is the metabolism of drugs that reduces their effective concentration at the site of action. Apart from the first-pass effect, the systemic bioavailability of the drug is also reduced by other factors, including incomplete absorption or chemical degradation of drugs.
Depending on the route of administration, drugs can be metabolized in the liver, intestine, lungs, and vasculature. Orally administered drugs are first absorbed through the...

Upper Respiratory Drugs: First and Second-Generation Antihistamines

288
Antihistamines are a class of drugs widely used to alleviate the symptoms of allergies, such as sneezing, itching, and nasal congestion. They work by inhibiting the actions of histamine, which is released by immune cells in response to allergenic substances or tissue injuries.
Histamine binds to specific receptor sites, known as H1 receptors, on tissue cells, triggering inflammation and swelling. Antihistamines combat these effects by competing with histamine for these receptor sites. By...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers01:26

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

174
Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

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...

Drugs for Treatment of Diarrhea-Predominant IBS01:17

Drugs for Treatment of Diarrhea-Predominant IBS

182
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Area of Science:

  • Oncology
  • Pharmacology
  • Drug Development

Background:

  • Non-small cell lung cancer (NSCLC) remains a leading cause of cancer-related mortality worldwide.
  • Targeted therapies inhibiting anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1) have improved outcomes for specific NSCLC patient populations.
  • Resistance to existing therapies necessitates the development of novel treatment strategies.

Purpose of the Study:

  • To summarize the key developmental milestones of iruplinalkib, a novel ALK and ROS1 tyrosine kinase inhibitor.
  • To highlight the regulatory approval of iruplinalkib in China for specific NSCLC patient groups.

Main Methods:

  • Review of preclinical and clinical development data for iruplinalkib.
  • Analysis of regulatory submission and approval processes in China.

Main Results:

  • Iruplinalkib (WX-0593) demonstrated high selectivity for ALK and ROS1 tyrosine kinases.
  • In June 2023, iruplinalkib received approval in China for locally advanced or metastatic ALK-positive NSCLC following progression or intolerance to crizotinib.

Conclusions:

  • Iruplinalkib represents a significant advancement in targeted therapy for ALK-positive NSCLC.
  • The approval marks a crucial milestone, offering a new therapeutic option for patients with specific genetic alterations in NSCLC.
