The tablets are the only product available in the market which may lead to liver toxicity upon long-term use. Being a class II drug, there is a need of some novel formulation for minimizing systemic toxicity of drug without compromising its therapeutic potential. Microsponges possess unique characteristics that makes it a versatile drug delivery carrier. Leflunomide loaded Microsponges were prepared with matrix forming polymer (ethyl cellulose) and stabilizer (poly vinyl alcohol) using quasi-emulsion solvent diffusion method. Two independent parameters, namely concentrations of polymer and stabilizing agent, were examined using a full 32 factorial design to determine their impact on particle size and % entrapment efficiency. The optimized formulation showed promising result for particle size (48.96 µm) and entrapment efficiency (89.45%) with spherical and tiny pores on surface. The optimized gel exhibited sustained release up to 8 h (91.46 ± 3.84%) with satisfactory results of flux and permeability coefficient. The developed formulation has good anti-inflammatory properties in wistar rats and a histopathology investigation on rats' skin verified its skin compatibility. The stability study showed stable formulation up to the period of 3 months.

Propranolol hydrochloride was selected as the model drug. Drug-loaded cores with different filling rates were prepared using SSE and characterized for appearance, hardness, XRD, and release properties. Shells with varying release windows were fabricated using FDM. Subsequently, shells and cores were assembled. Micro-CT was employed for microstructural characterization, while drug assay and release properties were assessed. The results indicated that cores exhibited a good appearance, and the SSE process had no effect on the crystal type. Adjusting the filling rate allowed for slight modulation of drug release while the shell structure effectively prolonged drug release. The CSRT displayed no significant internal defects, and the assay met the United States Pharmacopoeia-National Formulary 2024 (USP-NF 2024) requirements.

The optimized CLZ-TEs showed a mean particle size of 174 nm, polydispersity index of 0.173, zeta potential of -30 mV, and entrapment efficiency of 99%. TEM exhibited spherical nanovesicles and FTIR demonstrated compatibility of the excipients. Moreover, CLZ-TEG was homogeneous, smooth, and spreadable. Similarly, CLZ-TEG displayed sustained release and enhanced permeation of the CLZ.

To address these pharmacokinetic limitations, nanotechnology-based strategies have been explored to enhance drug solubility, systemic exposure, and targeted tissue distribution. This review critically examines the potential of nanocarrier-based formulations, including solid lipid nanoparticles, supersaturated self-nanoemulsifying drug delivery systems, lipid nanoemulsions, poly(lactic-co-glycolic acid) nanoparticles, and cubosomes, in optimizing darunavir pharmacokinetics. These approaches have demonstrated improved bioavailability, sustained drug release, lymphatic targeting, and enhanced blood-brain barrier penetration, offering promising avenues for optimizing HIV therapy while minimizing systemic toxicity. Further, this review discusses challenges associated with nanoformulation-based antiretroviral strategies, scalability, manufacturing challenges, potential toxicity, immunogenicity, long-term stability issues, and explores emerging innovations, such as multifunctional nanoparticles, targeted delivery platforms, and sustainable nanotechnology-based formulations.
