Hot melt extrusion is a versatile continuous manufacturing process extensively investigated for its applications with production of oral solid dosage forms, the aim of this study was to venture the applicability of HME in continuous manufacturing of topical semi-solid ointment formulations. Novel combination of a topical corticosteroid (Triamcinolone Acetonide) and local anesthetic (Lidocaine hydrochloride) were selected to be formulated with a water-soluble ointment base consisting of PEG 4000, PEG 1500 and Propylene glycol after performing appropriate drug-excipient compatibility studies. To determine the ratios of the solid to liquid components of the macrogol base, ‘quality by design’ approach was employed by …

Solid self-emulsifying drug delivery systems were developed instead of a conventional liquid system. Solid surfactants was chosen to emulsify lipids with different HLB properties. Type of surfactant, type of lipid, Lipid/surfactant L/S ratio, feed rate, screw speed and screw configuration, were the formulation and process parameters evaluated. Solid self-emulsifying drug delivery systems were successfully developed on the hot-melt extruder for the first time which is a continuous processing technology.

Many new drugs developed face oral delivery challenges and absorption due to poor biopharmaceutical properties. Formation of solid dispersions is a very widely applied technique for solubility enhancement of water insoluble drugs. In order to form stable solid dispersions it is important to select appropriate excipients that will maintain the drug in its amorphous form for an extended period of time. Selection of appropriate excipients is critical during the development of stable amorphous solid dispersions. The solubility parameter concept has been explored for theoretically identifying the excipients that will be suitable based on the structure of the active. In this …
