Inhaled Medications01:23

Inhaled Medications

342
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Dosage Regimen: Fixed Dose01:01

Dosage Regimen: Fixed Dose

1.9K
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

Drug Delivery: Miscellaneous Routes

426
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...

Drug Dosage Regimen: Overview01:15

Drug Dosage Regimen: Overview

3.7K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

Additional Routes of Drug Administration01:18

Additional Routes of Drug Administration

3.0K
Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Area of Science:

  • Inhalation Technology
  • Respiratory Device Engineering
  • Patient Adherence

Background:

  • Dry powder inhalers (DPIs) are diverse inhalation devices with varying feedback systems.
  • Effective drug delivery relies on correct inhaler use, which is influenced by user feedback.
  • Most multi-dose DPIs include dose counters, but feedback on inhalation technique varies significantly.

Purpose of the Study:

  • To analyze the feedback systems in commonly used multi-dose dry powder inhalers (DPIs).
  • To compare simple versus technologically advanced feedback mechanisms in DPIs.
  • To highlight the importance of inhalation process feedback for therapeutic efficacy.

Main Methods:

  • Review of the functioning of feedback systems in prevalent multi-dose DPIs.
  • Categorization of feedback mechanisms based on technological advancement.
  • Identification of DPIs providing specific user feedback on inhalation correctness.

Main Results:

  • All discussed multi-dose DPIs feature a dose counter.
  • Only Novolizer®, Genuair®, and NEXThaler® provide auditory and visual signals confirming correct inhalation.
  • These specific signals offer direct feedback on the inhalation process.

Conclusions:

  • Feedback systems in DPIs significantly impact user technique and adherence.
  • Auditory and visual feedback, as seen in Novolizer®, Genuair®, and NEXThaler®, are critical for ensuring correct inhaler use.
  • Improved inhaler technique through feedback is essential for achieving desired therapeutic effects.
