Division of Pharmacology.
Overview 
• What is inhaler? 
• Advantages Vs disadvantages 
• Types of inhalers 
– Properties 
– How to use 
– Advantages and disadvantages
1.What is inhaler? 
• An inhaler is a medical device used for 
delivering medication into the body via the 
lungs.
• Inhalant drugs 
1. Broncodilators 
2. Corticosteroids-Beclomethasone 
3. Mucolytic agents-Acetylcysteine 
4. Antimicrobials-Ribavirin, 
Tobramycin 
5. Immune modulators- 
Cyclosporine, Interferon α
6. Anesthetics-opiods
2.Advantages Vs Disadvantages 
• Advantages: 
1.Less systemic toxicity 
2.More rapid onset of medication 
3.Delivery to target of action 
4.Higher concentrations available in the lung
• Disadvantages: 
1.Time and effort consuming 
2.Limitation of delivery device
3.Devices 
1.Metered-dose inhalers
Properties 
A liquid propellant 
Inhalation technique is critical for optimal 
drug delivery
Inhaler devices
How to use 
Without chamber
1.Remove the cap from the MDI and shake well. 
2.Breathe out all the way. 
3.Place the mouthpiece of the inhaler between 
your teeth and seal your lips tightly around it. 
4.As you start to breathe in slowly, press down on 
the canister one time.
5. Keep breathing in as slowly and deeply 
as you can. (It should take about 5 to 7 
seconds for you to completely breathe in.) 
6. Hold your breath for 10 seconds (count to 
10 slowly) to allow the medication to reach 
the airways of the lung. 
7. Repeat the above steps for each puff 
ordered by your doctor. Wait about 1 minute 
between puffs.
8. Replace the cap on the MDI when 
finished. 
9. If you are using a corticosteroid MDI, you 
should use a valved holding chamber as 
described above.
With chamber
1.Remove the cap from the MDI and 
chamber. Shake well. 
2.Insert the MDI into the open end of the 
chamber (opposite the mouthpiece). 
3.Breathe out completely. 
4.Place the mouthpiece of the chamber 
between your teeth and seal your lips 
tightly around it.
5. Press the canister once. 
6. Breathe in slowly and completely through 
your mouth. If you hear a "horn-like" sound, 
you are breathing too quickly and need to 
slow down. 
7. Hold your breath for 10 seconds (count to 
10 slowly) to allow the medication to reach 
the airways of the lung.
8. Repeat the above steps for each puff 
ordered by your doctor. Wait about 1 minute 
in between puffs. 
9. Replace the cap on your MDI when 
finished. 
10. If you are using a corticosteroid MDI, 
rinse your mouth and gargle using water or 
mouthwash after each use. You should 
always use a chamber with a steroid MDI.
Advantages Vs Disadvantages 
Advantages 
•Rapid application 
•Handling 
•Multidose 
Disdvantages 
•Hand-breathe 
coordinations 
•İneffective use in poor 
ventilated patients 
•Oropharyngeal 
deposition and local 
side effects
2. Dry powder inhalers 
Single dose
Handihaler
Multi dose 
Discus inhaler 
Turbuhaler
Properties 
just dry-powder and no propulsion system. 
manual mechanism to insert one dose of 
dry-powder drug into the mouthpiece.
Inhaler devices
How to use 
1. To load a dose, hold the DPI with mouthpiece 
up to ensure proper loading of the medication. 
2.Twist the  grip fully in one direction as far as it 
will go and then fully back again. You will hear a 
click. The DPI is now loaded with a dose. 
3.Turn your head away from the inhaler and 
breathe out as much air as you comfortably can.
Inhaler devices
4. Place the device in your mouth and breathe in 
as forcefully and deeply as you can. 
5. Hold your breath for 10 seconds. 
6. Take the DPI away from your mouth and exhale 
slowly. 
7. If more than one dose is prescribed, repeat 
steps 1 through 5 for each dose. 
8. When your treatment is complete, replace the 
white cover and twist it completely to close
Advantages Vs Disadvantages 
Advantages 
•Less patient 
coordination required 
•Spacer not necessary 
•Compact Portable 
•No propellant 
•Usually higher lung 
deposition than a pMDI 
Disadvantages 
•Work poorly if inhalation is not 
forceful enough 
•Many patients cannot use them 
correctly (e.g.capsule handling 
problems for elderly 
•Most types are moisture 
sensitive. 
•Need to reload capsule each 
time
3. Nebulizer
Properties 
•The fundamental concept of nebulizer 
performance is the conversion of the 
medication solution into droplets in the 
respirable range of 1-5 micrometers
Inhaler devices
How to use
1. Place the compressor where it can safely reach its 
power source and where you can reach the ON/OFF 
switch. 
2. Wash your hands prior to preparing each treatment. 
3. Use a clean nebulizer. 
4. Measure the correct dose of medication and other 
solutions prescribed by your physician. Add these to the 
nebulizer. 
5. Connect the air tubing from the compressor to the 
nebulizer base. A finger valve may also be attached 
between the nebulizer base and tubing. Make sure all 
connections are snug. 
6. Attach a mouthpiece to the nebulizer.
Advantages Vs Disadvantages 
Advantages 
•Provide therapy for patients 
who cannot use other 
inhalation modalities (eg, MDI, 
DPI) 
•Allow administration of large 
doses of medicine 
•Patient coordination not 
required 
•Effective with tidal breathing 
•Dose modification possible 
•Can be used with 
supplemental oxygen 
Disadvantages 
•Decreased portability 
•Longer set-up and 
administration time 
•Higher cost 
•Electrical power source 
required 
•Contamination possible
