Welcome all to IS PHARMACOLOGY DIFFICULT Podcast! I am Dr Radhika
Vijay.


What do you know about Inhalational dosage forms? What are
different devices used to deliver these dosage forms? What are
different mechanisms and processes? Lets get to know all these...


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. This is how I will cover the basic
concepts and mechanism of these Inhalational dosage forms and
devices, a little lengthy talk but then right information at
right time makes the day a good valuable and truly bright one,
Isn't it?
