**11.1 Liposome for respiratory disorders**

Liposome formulations are used in lung disorders and respiratory aerosol which contains liposomes has more advantage compared to normal aerosol. Liposomal aerosols have advantages like sustained action, no local irritation, less toxicity and more stability [93]. Liposome products related to respiratory disorders available in market with brand names are ambisome, Myocet and Fungisome.
