How Loratadine Affects Patients

Desloratadine is a type of medicine that helps reduce allergy symptoms. It works by blocking one type of receptor (the H1 receptor) that histamine, a chemical released during an allergic reaction, attaches to. This prevents histamine from activating cells and producing the symptoms associated with allergies. Unlike other antihistamines, desloratadine does not enter the brain and does not cause drowsiness.

How Loratadine works in the body

Desloratadine helps to reduce allergy symptoms by blocking the effects of histamine. It does this by competing with histamine for binding to receptors in the body, keeping histamine from activating these receptors and causing symptoms. This provides temporary relief from symptoms like nasal congestion and watery eyes.

The advised dose of Loratadine is contingent upon the diagnosed condition, including Hay Fever, Nasal Congestion and non-nasal manifestations. The amount of dosage alters according to the technique of conveyance (e.g. Oral or Tablet, orally disintegrating - Oral) specified in the table below.

Loratadine for Inflammation of the Nose due to an Allergy

The recommended dosage of this medication is 10 mg once a day. However, I find that without taking at least 20 mg, I spend the whole struggling not to sneeze and my eyes are always red and itchy. Is it safe to take more than the recommended dose?

Loratadine for Allergic Conjunctivitis

I was told to take this medicine instead of Benadryl because I also take other medications. Unfortunately, this medication caused me a lot of problems: EXTREME itchiness and welts as well as a burning sensation all over my body. I only took it for 2 days before discontinuing use; thankfully, today I am fine.

Osteopathic Manipulative Treatment for Asthma

18 - 60
All Sexes
Mayfield Heights, OH

Asthma is a common respiratory condition that can be difficult to control despite the use of medications such as inhalers, oral steroids or even injectable medications. Osteopathic Manipulative Treatment (OMT) is a hands-on technique used to improve the chest structure and function and may help in improving breathing. Previous research showed that OMT in asthma patients, can improve the movement of the ribs and improve the "peak flow" which is the maximum rate at which a person can exhale air after taking a deep breath. However, no studies have evaluated the impact of OMT on lung inflammation. This single-site research study at University Hospitals aims to evaluate whether Osteopathic Manipulative Treatment (OMT) can reduce lung inflammation and improve breathing and lung function in adult patients with asthma. The lung function will be evaluated by Spirometry which is a test that measures how much air you can breathe in and out of your lungs, as well as how quickly and easily you can exhale air. The lung inflammation will be measured using a device that can detect how much you are breathing out Nitric Oxide which is a gas produced by inflamed cells in the lungs, this test is called: Fractional exhaled Nitric Oxide or FeNO. Approximately 100 participants will be enrolled.

Inhaled Corticosteroids + Azithromycin for Asthma

13 - 75
All Sexes
Aurora, CO

While asthma therapy is becoming more individualized based on asthma phenotypes, more research is needed to tailor newer therapies to individuals. Inhaled corticosteroid (ICS) medications are the foundation of care for all individuals with persistent asthma. But ICS use is not without possible long term side effects. This study will compare two currently available approaches to reduce AEX in primary care patients: (1) use of inhaled corticosteroids (ICS) as part of rescue therapy, also known as MART (Maintenance And Reliever Therapy) or PARTICS (Patient Activated Reliever Trigger Inhaled Corticosteriods) therapy - either of these therapies will be called Rescue-Inhaled Corticosteroids or R-ICS pronounced "Ricks," and (2) use of azithromycin (AZ) as a preventive therapy. These treatments will be studied both individually and in combination.

PF-07275315 for Asthma

18 - 70
All Sexes
Mobile, AL

The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-07275315) for the potential treatment of moderate-to-severe asthma. Asthma is a condition that makes it challenging to breathe, which negatively impacts the quality of life and functioning of people who are affected. This study is seeking participants who: * Are 18 to 70 years old * Have had moderate-to-severe asthma for at least 12 months that is not well controlled * Have been taking their regular maintenance treatment(s) for asthma over the last 12 months All participants will receive PF-07275315 or a placebo. A placebo does not have any medicine in it but looks just like the medicine being studied. PF-07275315 or placebo will be given as multiple shots in the clinic over the course of 12 weeks. We will compare the experiences of people receiving PF-07275315 to those of the people who do not. This will help us determine if PF-07275315 is safe and effective. Participants will be involved in this study for about 9.5 months. During this time, they will have 10 visits at the study clinic.

Corticosteroids for Asthma

18+
All Sexes
Hamilton, Canada

Most individuals with asthma can effectively manage their symptoms and maintain normal lung function using inhaled medications, unfortunately, there is a subset of asthma sufferers whose symptoms, lung function, and risk of asthma attacks remain unimproved despite conventional inhaled medications. There could be several reasons for this. One possibility is that inhaled medications fail to reach the intended areas within the lungs, due to structural abnormalities within the airways themselves. Much like road conditions or closures can impede the speed and efficiency of vehicle travel, factors such as airway narrowing or mucus blockages, which are common in asthma, can obstruct the passage of inhaled medications through the airways. Our team has now optimized advanced medical imaging techniques, including magnetic resonance imaging (MRI) and computed tomography (CT), required to investigate this. This study will use these imaging methods to visually assess and measure individual patients' airways and determine whether abnormal airway structures impact how well they respond to inhaled and orally delivered medications. We anticipate finding that abnormal airway structures make inhaled medications less effective, but that they do not affect the response to oral medications.
