Abstract:
Lung cancer is the most common cause of cancer-related deaths. Lung cancers can be classified as small-cell (SCLC) or non-small cell (NSCLC). About 84% of all lung cancers are NSCLC and about 16% are SCLC. For the past few years, there have been a lot of new advances in the management of NSCLC in terms of screening, diagnosis and treatment. Unfortunately, most of the NSCLCs are resistant to current treatments and eventually progress to advanced stages. In this perspective, we discuss some of the drugs that can be repurposed to specifically target the inflammatory pathway of NSCLC utilizing its well-defined inflammatory tumor microenvironment. Continuous inflammatory conditions are responsible to induce DNA damage and enhance cell division rate in lung tissues. There are existing anti-inflammatory drugs which were found suitable for repurposing in non-small cell lung carcinoma (NSCLC) treatment and drug modification for delivery via inhalation. Repurposing anti-inflammatory drugs and their delivery through the airway is a promising strategy to treat NSCLC. In this review, suitable drug candidates that can be repurposed to treat inflammation-mediated NSCLC will be comprehensively discussed together with their administration via inhalation from physico-chemical and nanocarrier perspectives.
Insights
Repurposing anti-inflammatory drugs offers a novel strategy for treating non-small cell lung cancer (NSCLC). Delivering these repurposed drugs via inhalation targets the inflammatory pathways driving NSCLC progression.
Area of Science:
- Oncology
- Pharmacology
- Biomedical Engineering
Background:
- Non-small cell lung cancer (NSCLC) is a leading cause of cancer mortality.
- Current treatments for NSCLC often face resistance, leading to advanced stages.
- Inflammation plays a critical role in NSCLC development and progression.
Purpose of the Study:
- To explore the repurposing of existing anti-inflammatory drugs for NSCLC treatment.
- To investigate the potential of targeting the inflammatory tumor microenvironment in NSCLC.
- To discuss novel drug delivery methods, specifically inhalation, for anti-inflammatory agents in NSCLC.
Main Methods:
- Review of existing anti-inflammatory drugs for repurposing potential in NSCLC.
- Analysis of the inflammatory pathways implicated in NSCLC.
- Evaluation of physico-chemical and nanocarrier properties for inhaled drug delivery.
Main Results:
- Identified suitable anti-inflammatory drug candidates for NSCLC repurposing.
- Highlighted the feasibility of targeting inflammation-mediated NSCLC.
- Discussed the advantages of inhaled drug delivery for NSCLC treatment.
Conclusions:
- Repurposing anti-inflammatory drugs is a promising strategy for NSCLC management.
- Inhaled delivery of these agents offers a targeted approach to treat inflammation-driven NSCLC.
- Further research into drug modification and nanocarriers is essential for optimizing inhaled therapy.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
