Summary
Medicinal aerosols offer new COPD and asthma treatments, including combination inhalers and smart devices. However, vaping poses risks, and adherence to inhaled medications remains a challenge.
Area of Science:
- Respiratory Medicine
- Aerosol Science
- Pharmacology
Background:
- Chronic Obstructive Pulmonary Disease (COPD) and asthma management often involve inhaled medications.
- The delivery and efficacy of medicinal aerosols are critical for treatment success.
- Emerging technologies and potential risks associated with aerosolized substances require ongoing review.
Purpose of the Study:
- To review recent advancements in medicinal and toxic aerosols.
- To highlight new therapeutic strategies for respiratory diseases.
- To discuss safety concerns and technological innovations in aerosol delivery.
Main Methods:
- Literature review of relevant publications on medicinal and toxic aerosols.
- Analysis of clinical trial outcomes and observational studies.
- Synthesis of data on drug efficacy, safety, and device technology.
Main Results:
- Combination inhalers (aclidinium bromide/formoterol fumarate) show superiority in COPD treatment.
- As-needed budesonide-formoterol is effective for mild-to-moderate asthma.
- Electronic nicotine delivery systems are linked to increased asthma exacerbations in children.
- Smart inhalers and inhaled hypertonic saline show promise for specific respiratory conditions.
- Inhaled liposomal amikacin improves sputum culture negativity in Mycobacterium avium complex disease.
- Surgical masks reduce bacterial aerosol burden in cystic fibrosis patients.
- E-cigarette or vaping-associated lung injury (EVALI) caused significant casualties in 2019.
Conclusions:
- Combination therapies and novel delivery systems are advancing respiratory care.
- Adherence to inhaled medications requires attention, particularly in adolescents.
- Risks associated with vaping necessitate public health awareness.
- Further research is needed to optimize aerosol-based therapies and mitigate risks.

01:20Asthma: Pathogenesis and Management
1.1K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
1.4K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:16Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
504
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
