The aim of this study was to determine whether swallowing whole or crushed tablets with an IDDSI Level 4 medication lubricant causes the rate and extent of drug absorption to be significantly different to swallowing whole tablets with water. An open-label, randomised, single-dose crossover study in 19 healthy adults was performed, in which a standard oral dose of immediate-release paracetamol tablets was administered. Whole or crushed tablets were swallowed with water, or with the medication lubricants Gloup Forte or Gloup Family. Passive unstimulated saliva was collected at regular intervals from 5 min to 8 h after swallowing and analysed using HPLC-UV. Pharmacokinetic parameters were estimated using a standard non-compartmental approach. Co-administering whole tablets with medication lubricant was considered to be bioequivalent to swallowing whole tablets with water in terms of absorption rate and extent, though there was a short delay in reaching the maximum concentration of 12–18 min. Crushing the tablets caused maximum concentration of paracetamol to increase by 36 %, a reminder to avoid crushing tablets if possible. Using a medication lubricant instead of water reduced the crushing-induced dose-dump by 9–18 %. Concerns based on <em>in vitro</em> dissolution test results are not substantiated when tested <em>in vivo</em>, and, for immediate-release paracetamol tablets, we find no evidence for concern regarding the impact of medication lubricants on drug absorption.

In recent years, nanoparticle-based drug delivery systems have emerged as a promising solution for addressing these limitations, offering the potential to deliver drugs precisely to the affected lung tissue while minimizing systemic side effects. This review explores various nanoparticle platforms, including liposomes, nanoemulsions, nanostructured lipid carriers, solid lipid nanoparticles, polymeric nanoparticles, niosomes, phytosomes, bilosomes, and micelles.

LipoDES extract was characterized by using a HPLC technique which assessed the presence of OA in the extract and allowed us to quantify it. Subsequently, several preconcentrates were realized mixing the LipoDES extract, used as oily phase, with different surfactants (Cremophor RH-40 and Cremophor EL) and co-surfactants (Labrasol ALF and ethanol) which are well known for their self-emulsifying properties.

Three possible formulations (S<sub>A</sub>, S<sub>F</sub> and S<sub>I</sub>) containing different amounts of extract were selected due to their low size and PDI and further investigated in terms of physical-chemical stability to temperature variations (stability at temperatures higher than 37 °C) and to dispersion and dilution in simulated gastrointestinal fluids. <em>In vitro</em> cytotoxicity and permeation studies were performed on CaCo-2 cells monolayer to prove the safety of SEDDSs and the ability of these systems to increase the permeability of OA.

Nowadays, nanotechnology is one of the advanced tools to enhance drug delivery and bioavailability. Hence, the prime goal of this study was to create safe gastro-protective therapy using methanol fruit extract of <em>Citrus medica</em> var. sarcodactylis (CMF) and its prepared nano formula (Nano-CMF). CMF or its nano form was given to rats at dose 600 mg/kg/day for a week along with a single oral administration of ethanol (5 ml/kg) at the 7th day. The particle size distribution of formulated CMF reflected the successful preparation of nano form, with average size 65 nm. Pretreatment with CMF or its nano formula to ethanol challenged rats significantly controlled the inflammatory response through down-regulated gastric HMBG1/TLR4/NF-κB signaling pathway and its downstream mediators at p < 0.001. Moreover, CMF or nano-CMF lessened oxidative stress incidence via modulating Nrf2 signaling pathway, sustaining prostaglandin content, and reducing gastric juice acidity with a significant p value less than 0.001, as compared to the EtOH-intoxicated rats. In addition, nano form effectively preserved the gastric mucosal integrity and alleviated apoptosis in gastric cells as validated by ulcer index (p < 0.001), and the histological and immunohistochemical findings, when matched to the EtOH-treated group. The metabolomics analysis revealed the characterization of 36 compounds.
