Potential of a Cyclone Prototype Spacer to Improve In Vitro Dry Powder Delivery
This was reported in 6. Moreover, the aerodynamic diameters of particles emitted from the cyclones were halved compared to the DPIs alone e.
Deposition of particles in the next generation impactor and within the devices was determined by high performance liquid chromatography. Results Reduced induction port deposition of the emitted particles from the cyclones was observed due to the high retention of the drug within the spacers e.
Fine particle fractions of aerosol as emitted from the cyclones were substantially higher than the DPIs alone. Moreover, the aerodynamic diameters of particles emitted from the cyclones were halved compared to the DPIs alone e. Conclusion This work has shown the potential of employing a cyclone spacer for commercial carrier-based DPIs to improve inhaled drug delivery. One of the main advantages of DPIs compared to metered dose inhalers MDIs is surely the avoidance of a requirement for actuation-inhalation co-ordination by the user 2.
Nevertheless, passive DPIs pose some major challenges as a universal therapy of lung diseases. The de-aggregation of the formulation into an aerosol suitable for inhalation is dependent on the interaction between a powder formulation and the airflow which is drawn through the device 3 — 5.
Many patients with obstructive lung disease are unable to generate an aerosol cloud through high resistance devices 6. In traditional products, even with formulations optimized for in vitro drug delivery, the in vivo efficiency lung deposition of DPIs has been reported to be low and to be variable 7. The degree of throat deposition has been identified as a major cause of variability in efficiency of marketed DPIs and MDIs 8.
The success of inhalation therapy depends on the complex interaction between a powder formulation and the airflow drawn through a DPI. In most cases the device design is optimized to maximize aerosolization of a specific formulation using in vitro testing. The majority of DPIs 9 contain a blend of micronized drug particles blended with non-respirable carrier particles.
Micronized particles which are not removed from the carrier upon inhalation are unable to reach the lung, depositing instead within the oropharynx 5. Oropharyngeal deposition is well understood with MDIs, where large droplets with high velocity deposit in the throat—one of the leading causes of side-effects in inhalation therapy In order to avoid such problems with MDIs, the use of spacer chamber is recommended to reduce the velocity and droplet size of the aerosol ultimately inhaled by the patient; thereby reducing the oropharyngeal deposition The magnitude of the fine particle respirable dose emitted from DPIs has been clearly demonstrated to depend on the airflow rate through many commercial devices 4 , 6.
Several clinical studies report variability in the magnitude of inspiratory flows generated by patients when using DPIs 6 , 12 , 13 and many patients with lung disease struggle to inhale with sufficient strength through medium-to-high resistance devices. The result is high variability in the liberation of fine inhalable particles from marketed DPIs that were well characterized using in vitro testing 14 , Use with care in children.

Updated on January 14, Print You may think the answer to this question is easy—that a person knows when their inhaler is empty when it stops spraying. Therefore, it is possible to continue to use an asthma inhaler while inhaling only propellant and no medicine.
The currently available albuterol inhalers, with the exception of Ventolin HFA , do not have a dose-counter on the inhaler. A Simple Calculation Inhalers that contain steroids are used on a regular basis to prevent asthma symptoms from occurring: For this reason, they often are called "controller" inhalers.
Since they typically are used a predetermined number of times per day or week , it's possible to determine when the inhaler is empty in three simple steps: Note the number of inhalations contained in your asthma inhaler when it is new from the pharmacy.
This number should be clearly printed on the box or you can ask your pharmacist. For most steroid inhalers, this number is Consider the number of puffs you take every day from your inhaler. This will vary depending on the severity of your asthma and your doctor's orders. Divide the number of inhalations in the device by the number of puffs you take each day. This will tell you how many days the medication will be available.
For example, if your inhaler contains inhalations and your doctor has you take two puffs twice a day, that's a total of four puffs per day.
Bronchospasm is a sudden tightening of the muscles in your airway. This causes your airways to become narrow, allowing less air to flow through as you breathe. Less airflow through your lungs leads to less oxygen being delivered into your body. Common symptoms of bronchospasm include wheezing a whistling sound when you breathe , coughing, and chest pain or tightness.
Bronchospasm commonly occurs in people with asthma. For some people, it can also occur during exercise or other physical activities. What does Ventolin HFA do? It does this by attaching to beta2-receptors attachment sites that are on certain muscles in your airways. When Ventolin HFA attaches to these receptors, it causes the muscles to relax.
As the muscles relax, your airways open and become wider. This allows air to flow through them more freely as you breathe. This medication is meant to be used to quickly relieve bronchospasm symptoms. How long does it take to work? In a clinical study , people had an improvement in their breathing on average about 5 minutes after using Ventolin HFA. Their average time until having maximum improvement in their symptoms was 56 minutes.
Ventolin HFA precautions This drug comes with several precautions. Before taking Ventolin HFA, talk with your doctor about your health history. Ventolin HFA may not be right for you if you have certain medical conditions or other factors affecting your health. These include: Seizure disorders. Ventolin HFA can worsen seizure disorders in people who already have these conditions.
Ventolin HFA can worsen the symptoms of hyperthyroidism high thyroid hormone level in people who already have this condition.
Ventolin HFA can worsen diabetes and certain complications of diabetes in people who already have these conditions. Heart problems. Ventolin HFA can cause heart problems and high blood pressure in some people. This drug may not be safe for you if you have heart disease or high blood pressure. Talk with your doctor about any history of heart or blood pressure problems to see if Ventolin HFA is safe for you.
Allergic reaction. Ventolin HFA expiration, storage, and disposal When you get Ventolin HFA from the pharmacy, the pharmacist will add an expiration date to the label on the bottle. This date is typically 1 year from the date they dispensed the medication. The expiration date helps guarantee the effectiveness of the medication during this time.
If you have unused medication that has gone past the expiration date, talk to your pharmacist about whether you might still be able to use it. Storage How long a medication remains good can depend on many factors, including how and where you store the medication.
