Summary
This study compared free and nanoparticle Cabazitaxel (CBZ) lung cancer treatments. Nanoparticle formulations administered via inhalation showed reduced toxicity and improved retention compared to intravenous routes.
Area of Science:
- Pharmacology
- Nanotechnology
- Oncology
Background:
- Intravenous (IV) chemotherapy is standard for lung cancer, but pulmonary (inhaled) administration offers an alternative.
- Cabazitaxel (CBZ) is a chemotherapy drug used for lung cancer.
Purpose of the Study:
- To investigate the biochemical and histological effects of free and nanoparticle CBZ formulations after IV and inhaled (INH) administration in rats.
- To evaluate the efficacy and toxicity of a novel PEGylated polystyrene nanoparticle (NP) formulation of CBZ.
Main Methods:
- Rats received free CBZ or CBZ NP formulations via IV or INH routes.
- Biochemical and histological parameters were assessed.
- Blood samples were collected at 24 and 48 hours post-administration.
- Nanoformulations were prepared using PEGylated polystyrene nanoparticles via PISA.
Main Results:
- Free CBZ formulations (IV or INH) exhibited higher systemic toxicity.
- CBZ NP formulations showed no toxicity via either IV or INH routes.
- Inhaled CBZ NP formulations demonstrated enhanced and prolonged drug retention in the lungs.
- Histological analysis revealed increased alveolar macrophage migration with inhaled CBZ NP due to enhanced retention.
Conclusions:
- Nanotechnology combined with the pulmonary route offers an advantage for developing inhalable nanomedicines for lung cancer.
- The inhaled nanoparticle formulation of CBZ presents a potentially safer and more effective treatment strategy for lung cancer.

Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...

1.9K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

01:16Drug Delivery: Overview
274
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

01:15Non-Oral Extravascular Drug Absorption Routes
193
Non-oral extravascular routes, which encompass sublingual, buccal, topical, intramuscular, and inhalation methods, primarily utilize passive diffusion to transport drugs into the systemic circulation. The absorption rates and effectiveness of these routes depend on the drug's physicochemical properties, as well as the patient's anatomical and pathophysiological state.
Lipophilic drugs that are stable at salivary pH (6) and exhibit minimal binding to the oral mucosa are absorbed more...

01:29Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
