Pharmacology tip! 💊 Zafirlukast & montelukast are leukotriene receptor antagonists that are prescribed for long-term asthma control.
They help to decrease ⬇️ how reactive hypersensitive bronchioles are...hopefully stopping them from spasming and causing an asthma attack any time the client is exposed to a trigger!
Will this help your client during an asthma attack? Nope! Not a bit. During an asthma attack, you will focus on medications that can immediately open up your client's airway, such as albuterol!
But once they have recovered, and you're looking to prevent future attacks, montelukast or zafirlukast might be just the thing.
How are you going to remember this? Well, you must know generic names on the NCLEX, but you don't have to memorize every drug out there. 😉
Notice both of these medications end in -lukast. If you see any medication with that ending, you'll know you're dealing with a leukotriene receptor antagonist!
There are TONS of these common endings that can help you with pharmacology and stop you from memorizing your entire drug guide.

Zafirlukast and montelukast are important leukotriene receptor antagonists used primarily for the long-term management of asthma and exercise-induced bronchospasm. These medications work by blocking leukotrienes, which are inflammatory chemicals that cause bronchoconstriction, mucus production, and swelling in the airways leading to asthma symptoms. Their primary function is to decrease the hypersensitivity of bronchioles to various triggers, preventing spasms that result in asthma attacks. However, it is crucial to understand that these drugs are not effective during an acute asthma attack. During such events, quick-relief bronchodilators like albuterol are essential to immediately open the airways and restore breathing. Besides asthma, montelukast and zafirlukast have off-label indications including angioedema, anaphylaxis, and erythema nodosum. Despite their benefits, they may cause adverse effects such as hallucinations, depression, aggressive behavior, and a rare but serious condition called Churg-Strauss syndrome. Hence, monitoring respiratory status and overall patient well-being is vital when prescribing these agents. Nursing care involves administering these medications at least two hours before meals and advising patients on consistent daily dosing for optimal results, especially in exercise-induced bronchospasm prevention. Patients should be encouraged to report any changes in urinary patterns or unusual neuropsychiatric symptoms promptly. For students preparing for the NCLEX exam, recognizing the "-lukast" suffix can aid in identifying leukotriene receptor antagonists. This pharmacological tip can reduce memorization burdens by grouping similar medications through their common suffixes. Understanding the role of zafirlukast and montelukast within asthma treatment pathways enhances safe and effective patient care. It reinforces the need for a dual approach combining immediate relief medications during attacks and preventive therapies to reduce frequency and severity of future episodes. This knowledge is crucial for nurses, respiratory therapists, and other healthcare providers managing asthma patients.
