Abstract:
This review describes the use of lipid-based nanocarriers (LNCs) for the parenteral delivery of pharmaceutical actives. Firstly, the two generations of LNCs, namely solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs), are explained in terms of preparation, characterization and stability. Although the use of LNCs through parenteral administration has shown many benefits, their use is limited by opsonization, an immune process that causes their short half-life (3-5 min). Therefore, many strategies are discussed to realize "stealth" systems suitable for parenteral administration. The requirements and applications of parenteral lipid nanoparticles are reviewed for the delivery of natural compounds, synthetic drugs and genetic materials. Recently, the latter application has been of remarkable interest due to the numerous benefits of mRNA vaccines to fight the Covid-19 pandemic.

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...
Routes of Drug Administration: Parenteral
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...

Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...
