摘要：Microencapsulation represents a process that can create targeted, controlled release kinetics of drugs, thus optimizing therapeutic efficacy. Our group has investigated the impact of this technology on Wistar rats to determine pharmacological efficacy of basil extracts. Animals were treated with water extract of Ocimum basilicum in microvesicles and with combination of basil extracts and 3α,7α-dihydroxy-12-keto-5-cholanate, also known as 12-monoketocholic acid (MKC) acid in microvesicles for 7 days. Alloxan was used to induce hyperglycemia. Pharmacological effects on glycemia were evaluated by measuring blood glucose levels in alloxan-induced diabetic rats. Microvesicles were prepared using the Büchi-based microencapsulating system developed in our lab. The dose of basil extract that was orally administered in rats was 200 mg/kg and the dose of MKC acid was 4 mg/kg as per established protocols. A seven-day treatment with basil aqueous extract, as well as a combination of basil and MKC acid extract in the pharmaceutical formulation, led to a statistically significant reduction in the blood glucose concentration of animals with alloxan-induced hyperglycemia compared to pre-treatment values (p < 0.05 and p < 0.01), which indicates that basil has hypoglycemic and antihyperglycemic effects. Microvesicles, as a pharmaceutical-technological formulation, substantially enhance the hypolipidemic action of basil extract with MKC acid.
