Montelukast Pharmacology

Montelukast Pharmacology

On this episode, I discuss montelukast pharmacology

Montelukast is a leukotriene receptor antagonist. Leukotrienes play an important role in causing inflammation and smooth muscle contraction in asthma and allergic rhinitis.

Because montelukast blocks the effects of leukotrienes, it can be advantageous to use this medication for allergies and asthma.

It is important to remind patients that montelukast is NOT a substitute for an acute relief medication like albuterol in the management of asthma symptoms.

Montelukast has been reported to cause mood and behavioral changes and it is important to monitor our patients for these rare concerns.

Pseudoephedrine Pharmacology

Pseudoephedrine is commonly used to help relieve nasal congestion.

There are some adverse effects you need to be aware of with pseudoephedrine. Insomnia, increase in blood pressure, and urinary retention are all possible.

When I assess a patient using pseudoephedrine, I like to investigate blood pressure, history of urinary problems and insomnia history.

Pseudoephedrine can cause the prescribing cascade.  I lay out examples in the podcast.

Pseudoephedrine should not be utilized with MAOI’s if possible – I discuss the reason for this in the podcast.
