SEDDS (self-emulsifying drug delivery system) are of particularly relevant for the production of isotropic mixtures of oil, surfactant, co-surfactant, and drug in order to solve their physicochemical problems. Clarithromycin (CLA), a macrolide, has a 50 percent absolute bioavailability. The goal of this work was to create a liquid SEDDS system for CLA in order to increase solubility by increasing interfacial surface area and thereby boosting absorption. Clarithromycin SEDDS were produced with isopropyl myristate as the oily phase, Cremophor EL, Tween 80, Brij 58 as surfactants, and isopropyl alcohol, isobutanol, and transcutol EL as co-surfactants. Clarithromycin solubility was studied in a variety of vehicles, including isopropyl myristate, Cremophor EL, brij 58, tween 80, isopropyl alcohol, isobutanol, and transcutol RH, with isopropyl myristate yielding around 112.35 mg/ml. Formulations F9, which contain Brij 58 as a surfactant and transcutol RH as a co-surfactant, have a 120m minimum globule size, a 15-20 sec self-emulsification time, and maximal drug release. The ideal composition of formulation F9 SEDDS was resolute based on the findings of phase separation, self-emulsification, percentage transmittance, globule size, drug release, zeta potential, resilience to dilution, cloud point measurement, drug content, and dispersibility investigations.
