Abstract

Solid lipid nanoparticles (SLNs) are one of the extensively utilized nanocarriers in the pharmaceutical field due to their biocompatibility and biodegradability. These features of the carrier system have fuelled its use as the drug delivery system since the last three decades. This review presents different SLN preparation techniques, such as high shear homogenization, hot homogenization, cold homogenization, microemulsion-based technique, . The physicochemical nature of SLNs, comprising drug loading, drug release, particle size, zeta potential, stability, cytotoxicity, and cellular uptake, has been concisely discussed. The article also explains why SLNs are preferred to develop drug delivery systems in several pharmaceutical preparations. The key ingredients like lipid, surfactant/stabilizer accompanied by co-surfactant, cryoprotectant, or charge modifiers used to fabricate SLNs are also briefly conferred. Here is an elaborate discussion of drugs that are used through various routes by the SLN carrier system and their outcome for utilization of this system. Regulatory aspects, patent aspects, and future prospects of SLN are also discussed here.
