Actions and spectrum:
Budesonide is a type of corticosteroid, which is a type of steroid hormone that acts to reduce inflammation in the airways. It is often used as a preventive treatment for asthma, helping to reduce the frequency and severity of asthma attacks. Budesonide is inhaled directly into the lungs, and its effects are generally localized to the airways, reducing the risk of systemic side effects.
Formoterol, on the other hand, is a type of bronchodilator, which means it works to relax the muscles in the airways, making it easier to breathe. It is often used as a quick-relief medication for asthma, helping to relieve symptoms during an asthma attack. Formoterol is also inhaled directly into the lungs.
In terms of their spectrum of action, budesonide is generally considered to be a more broad-spectrum medication, as it acts to reduce inflammation in the airways, which is a key factor in many respiratory disorders, including asthma and COPD. Formoterol, on the other hand, is more targeted towards the specific symptom of airflow obstruction, and is therefore generally considered to have a more limited spectrum of action.

Black box warning:
The patients with COPD should not use Budesonide/Formoterol to treat sudden symptoms of bronchospasm, as it is not a rescue medication for this condition either.

Pregnancy consideration:
USFDA pregnancy category: not assigned
Lactation: safety and efficacy not established
Pregnancy category:
Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester.
Category B: There is no evidence of risk to the fetus found in animal reproduction studies and there are not enough studies on pregnant women.
Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for an effect in humans, care must be taken for potential risks in pregnant women
Category D: There is adequate data available with sufficient evidence of human fetal risk from various platforms, but despite potential risks may be used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh risks over benefits These category drugs should be prohibited for pregnant women.
Category N: There is no data available for the drug under this category.
Pharmacology:
Budesonide is a steroid that works by reducing inflammation in the airways, which helps to relieve airway narrowing and improve breathing. Formoterol is a beta-2 agonist that works by relaxing the smooth muscle in the airways, which helps to relieve airway narrowing and improve breathing.
When taken by inhalation, Budesonide/Formoterol is rapidly absorbed into the bloodstream and reaches the lungs, where it acts to control asthma and COPD symptoms. The medication is generally well tolerated, but some patients may experience side effects, such as headache, throat irritation, and hoarseness.
Pharmacodynamics
Pharmacokinetics
Administration
Metered-dose inhaler (MDI): Shake the inhaler well before each use. Remove the cap and breathe out fully. Breathe in deeply and steadily while pressing down on the canister to release the medication. If more than one dose is needed, wait a minute or two before taking the second dose.
Dry powder inhaler (DPI): Follow the instructions that come with the specific DPI you are using. In general, the DPI should be shaken well before each use. Breathe out fully and then place the mouthpiece in your mouth. Breathe in deeply and steadily to inhale the medication. If more than one dose is needed, wait a minute or two before taking the second dose.

Why do we use budesonide?
The uses of Budesonide/Formoterol:
Asthma: Budesonide/Formoterol is used to control symptoms of asthma, such as wheezing, coughing, and shortness of breath. It is used in patients whose asthma is not well controlled with other medications or in patients who require a combination of a steroid and a bronchodilator to control their asthma.
Chronic Obstructive Pulmonary Disease (COPD): Budesonide/Formoterol is used to treat COPD. It is used to relieve symptoms, such as shortness of breath and wheezing, and to improve lung function.
