Formoterol
Formoterol, also known as eformoterol, is a long-acting β2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD). Formoterol has an extended duration of action (up to 12 h) compared to short-acting β2 agonists such as salbutamol (albuterol), which are effective for 4 h to 6 h. Formoterol has a relatively rapid onset of action compared to other LABAs, and is effective within 2-3 minutes. The 2022 Global Initiative for Asthma report recommends a combination formoterol/inhaled corticosteroid inhaler as both a preventer and reliever treatment for asthma in adults. In children, a short-acting β2 adrenergic agonist (e.g., salbutamol) is still recommended. It was patented in 1972 and came into medical use in 1998. It is available as a generic medication. It is also marketed in the combination formulations budesonide/formoterol and mometasone/formoterol. Side effects In November 2005, the US Foo ...

Mometasone/formoterol
Mometasone/formoterol, sold under the brand name Dulera among others, is a fixed-dose combination medication used in the long-term treatment of asthma. It contains mometasone a steroid and formoterol a long-acting beta agonist. It is only recommended in those for whom an inhaled steroid is not sufficient. It is used by inhalation. Common side effect include headache and sinusitis. More serious side effects may include thrush, immunosuppression, allergic reactions, and cataracts. Use is not recommended in those less than twelve years of age. It has not been studied during pregnancy or breastfeeding. Mometasone works by decreasing inflammation while formoterol works by relaxing smooth muscle in the airways. The combination was approved for medical use in the United States in 2010. No generic version is available . In 2021, it was the 215th most commonly prescribed medication in the United States, with more than 1million prescriptions. It is on the World Health Organization' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Budesonide/formoterol
Budesonide/formoterol, sold under the brand name Symbicort among others, is a fixed-dose combination medication used in the management of asthma or chronic obstructive pulmonary disease (COPD). It contains budesonide, a steroid; and formoterol, a long-acting β2-agonist (LABA). The product monograph does not support its use for sudden worsening or treatment of active bronchospasm. However, a 2020 review of the literature does support such use. It is used by breathing in the medication. Common (≥1/100 to <1/10) side effects include , , , |
Salmeterol
Salmeterol is a Long-acting beta-adrenoceptor agonist, long-acting β2 adrenergic receptor agonist (LABA) used in the treatment and prevention of asthma symptoms and control of chronic obstructive pulmonary disease (COPD) symptoms. Symptoms of bronchospasm include Dyspnea, shortness of breath, Wheeze, wheezing, coughing and chest tightness. It is also used to prevent breathing difficulties during exercise (exercise-induced bronchoconstriction). It was patented in 1983 and came into medical use in 1990. It is marketed as Serevent in the US. It is available as a dry-powder inhaler (DPI) that releases a powdered form of the drug. It was previously available as a metered-dose inhaler (MDI) but was discontinued in the US in 2002. It is available as an MDI in other countries as of 2020.

Bronchodilator
A bronchodilator or broncholytic (although the latter occasionally includes secretory inhibition as well) is a substance that dilates the bronchi and bronchioles, decreasing resistance in the respiratory airway and increasing airflow to the lungs. Bronchodilators may be originating naturally within the body, or they may be medications administered for the treatment of breathing difficulties, usually in the form of inhalers. They are most useful in obstructive lung diseases, of which asthma and chronic obstructive pulmonary disease are the most common conditions. They may be useful in bronchiolitis and bronchiectasis, although this remains somewhat controversial. They are often prescribed but of unproven significance in restrictive lung diseases. Bronchodilators are either short-acting or long-acting. Short-acting medications provide quick or "rescue" relief from acute bronchoconstriction. Long-acting bronchodilators help to control and prevent symptoms. The three types of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Racemic Mixture
In chemistry, a racemic mixture or racemate () is a mixture that has equal amounts (50:50) of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates. History The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. He manually separated the crystals of a mixture, starting from an aqueous solution of the sodium ammonium salt of racemate tartaric acid. Pasteur benefited from the fact that ammonium tartrate salt gives enantiomeric crystals with distinct crystal forms (at 77 °F). Reasoning from the macroscopic scale down to the molecular, he reckoned that the molecules had to have non-superimposable mirror images. A sample with only a single enantiomer is an ''enantiomerically pure'' or ''enantiopure'' compound. Etymology The word ''racemic'' derives from Latin , meaning pertaining to a ...

Metered-dose Inhaler
A metered-dose inhaler (MDI) is a device that delivers a specific amount of medication to the lungs in the form of a short burst of aerosolized medicine that is usually self-administered by the patient via inhalation. It is the most commonly used delivery system for treating asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. The medication in a metered dose inhaler is most commonly a bronchodilator, corticosteroid or a combination of both for treating asthma and COPD. Other medications less commonly used but also administered by MDI are mast cell stabilizers, such as cromoglicate or nedocromil. Description A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the patien ...

Dry-powder Inhaler
A dry-powder inhaler (DPI) is a device that delivers medication to the lungs in the form of a dry powder. DPIs are commonly used to treat respiratory diseases such as asthma, bronchitis, emphysema and COPD although DPIs (such as inhalable insulin) have also been used in the treatment of diabetes mellitus. DPIs are an alternative to the aerosol-based inhalers commonly called metered-dose inhaler (or MDI). The DPIs may require some procedure to allow a measured dose of powder to be ready for the patient to take. The medication is commonly held either in a capsule for manual loading or in a proprietary form inside the inhaler. Once loaded or actuated, the operator puts the mouthpiece of the inhaler into their mouth and takes a sharp, deep inhalation (ensuring that the medication reaches the lower parts of the lungs), holding their breath for 5–10 seconds. There are a variety of such devices. The dose that can be delivered is typically less than a few tens of milligrams in a sin ...

Common side effects with the inhaled form include respiratory infections, cough, and headaches. Common side effects with the pills include feeling tired, vomiting, and joint pains. Serious side effects include an increased risk of infection, loss of bone strength, and cataracts. Long-term use of the pill form may cause adrenal insufficiency. Stopping the pills suddenly following long-term use may therefore be dangerous. The inhaled form is generally safe in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beta2-adrenergic Receptor Agonist
Beta2-adrenergic agonists, also known as adrenergic β2 receptor agonists, are a class of drugs that act on the β2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation. β2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle and liver, relaxation of uterine muscle, and release of insulin. They are primarily used to treat asthma and other pulmonary disorders. Bronchodilators are considered an important treatment regime for chronic obstructive pulmonary disease (COPD) and are usually used in combination with short acting medications and long acting medications in a combined inhaler. Mechanism of action Activation of β adrenergic receptors leads to relaxation of smooth muscle in the lung, and dilation and opening of the airways. β adrenergic receptors are coupled to a stimulatory G protein of adenylyl cyclase. This enzyme produces the second messenger cyclic adenosine monophos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
