Firstly waiving a green flag to today's conversation, I will comment on Inhalant, Aerosols and finally Spinhalers. Firstly i will tell you which drugs can be given as Inhalations. Then I will be starting the real detailed talk about Metered Dose Inhalers (MDIs) and different types of devices like rotahalers, turbohalers, Nebulisers and spinhalers. Details about pressured Metered Dose Inhalers (pMDIs) are covered first.Their mechanism, limitations and benefits are thrown light upon, Next I will be shifting the discussion focus towards Nebulisers, where I will be covering definition, mechanism, two types of Nebulisers mainly Jet nebulisers or Pneumatic nebulisers and Ultrasonic nebulisers. I will tell you the principles of these two and in general facts about nebulisers, advantages and disadvantages.
Finally covering details about Rotahalers, capsule is Rotacap, its punctured and drug is released, aerosolised. 
Next i will talk about General facts about aerosolised drug particles, generally 1-5 micro meter in diameter, It will decrease efficacy if particle size is big or too small, so it should be apt in this range.
