Hyperlipidemia and its associated cardiovascular complications are the major causes of mortality and disability worldwide. Simvastatin (SIM) is one of the most commonly prescribed lipid-lowering drugs for the treatment of hyperlipidemia by competitive inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. However, the extensive first-pass metabolism leading to low oral bioavailability and frequent daily doses may lead to poor patient compliance and adverse effects caused by plasma fluctuations.

However, oral administration of diclofenac often leads to adverse effects. This study introduces an innovative nano-in-micro approach to create diclofenac nanoparticle-loaded microneedle patches aimed at localised, sustained pain relief, circumventing the drawbacks of oral delivery.

Despite the high pharmacological activity these drugs may have, their limited water solubility leads to poor absorption and consequently to sub-therapeutic drug concentrations in target tissues. The formulation of drug nanocrystals (NCs) has emerged as one the most promising approaches for increasing the biopharmaceutical performance of hydrophobic drugs.
