Abstract:
Conventional drug delivery systems have limitations according to their toxicity and poor solubility, bioavailability, stability, and pharmacokinetics (PK). Here, we highlight the importance of functionalized titanate nanotubes (TNTs) as targeted drug delivery systems. We discuss the differences in the physicochemical properties of TNTs and carbon nanotubes (CNTs) and focus on the use of functionalization to improve their characteristics. TNTs are promising materials for drug delivery systems because of their superb properties compared with CNTs, such as their processability, wettability, and biocompatibility. Functionalization improves nanoparticles (NPs) via their surface modification and enables them to achieve the targeted therapy.

Drug Delivery: Parenteral Route
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...
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...
Drug Delivery: Miscellaneous Routes
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.
