This inquiry focuses on liposomes as its subject matter. Liposomes are an excellent means of increasing the period of time during which an impact is active from hours to months. In the current investigation, liposomal formulations of metformin hydrochloride were created and analysed by the researchers. Because its plasma half-life is much shorter than that of other drugs (t1/2 = 1.5 h), the patient has to take the drug more often in order to keep its concentration in steady state plasma. In this study, liposomal formulations of metformin were tested for drug entrapment, surface characterisation, in-vitro drug release investigations, release kinetics, and their underlying processes. Study concludes that the development of liposomal solutions of metformin hydrochloride was a fruitful endeavour.

Nowadays emulgel systems are currently of attention to the pharmaceutical scientists because of their substantial potential to act as drug delivery vehicle by incorporating a broad range of drug molecules. Emulgel is one of the recent technology in NDDS used topically having characteristics of dual control release i.e. emulsion as well as gel. Emulgels have emerged as one of the most interesting topical delivery systems as it has dual release control system i.e. gel and emulsion. When gel and emulsion are used in combined form, the dosage form are referred as emulgel. In current review article, various aspects of the emulgel are discussed.
