ABSTRACT
Solid lipid nanoparticles (SLNs) are gaining significant attention in the pharmaceutical industry due to their biocompatibility and biodegradability, making them a popular functional nanocarrier. SLNs are a popular nanocarrier due to their ability to bypass the spleen and liver, offer high drug stability, and improve bioavailability, sterilization, immobilization, targeted drug release, and biocompatible ingredients. This article discusses various SLN preparation techniques, including high shear homogenization, hot homogenization, cold homogenization, microemulsion-based, solvent evaporation, solvent emulsification-evaporation, supercritical fluid-based, spray drying, double emulsion, and precipitation techniques, focusing on methodological aspects. This review discusses the physicochemical behavior of SLNs, including drug loading, release, particle size, stability, cytotoxicity, and cellular uptake, and their major biomedical applications.
ABSTRACT
OBJECTIVE: To compare the efficacy of intravenous acetaminophen and intravenous diclofenac sodium in the management of skeletal vaso-occlusive crisis among children with sickle cell disease. DESIGN: Single blind randomized controlled trial. SETTING: Tertiary care hospital. PARTICIPANTS: 104 children with sickle cell disease and skeletal vaso-occlusive crisis. INTERVENTION: Intravenous acetaminophen at 10mg/kg/dose 8 hourly and intravenous diclofenac sodium at 1mg/kg/dose 8 hourly in 1:1 ratio. MAIN OUTCOME MEASURES: Reduction in pain score (50%), number of doses needed to relieve pain after 24 hours of drug administration and decrease in pain score at 1 hour. RESULTS: A 50% reduction in pain score was seen in 35 (77.3%) and 10 (21.7%) children among acetaminophen and diclofenac sodium groups respectively (RR, 95% CI 3.6; 2.02-6.33, P< 0.001). The mean (SD) fall in pain score at 1 hour was significantly higher among intervention arm as compared to control arm [1.51 (0.5) and 1.06 (0.5); P<0.001]. Eight (17.4%) patients developed local phlebitis at the site of infusion among diclofenac group. CONCLUSIONS: Intravenous acetaminophen is a better alternative to intravenous diclofenac in children with skeletal vaso-occlusive crisis.
