Satranidazole is a drug that helps to combat a large number of varied health disorders effectively. This drug participated in clinical trials in patients of amebic liver abscess, where it showed a far lower incidence of side effects and had a significantly better tolerance than metronidazole. Besides, satranidazole has been studied an adjunct to scaling and root planning in the treatment of chronic periodontitis. satranidazole has a low polar surface area, high dose, and dosing frequency. Nanosizing with appropriate stabilizers and programmed processing conditions successfully produced SAT-NC with improved pharmaceutic and pharmacokinetic characteristics.
