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.

Quinolones are a class of antibiotics that can be used for various infections. I discuss the pharmacology, adverse effects, drug interactions and other items on this podcast episode.

On this episode, I talk about the warnings associated with quinolones.

Quinolone use has subsided over time, not due to the fact that they are ineffective, but to rising concerns and warnings about adverse effects.

Quinolones can interact with quite a few medications.  I’ve seen a case of amiodarone and levofloxacin contributing to QTc prolongation which I discuss on this episode.

It is critical to remember the binding interactions associated with quinolones as these can potentially lead to treatment failure.

Metoclopramide Pharmacology

Metoclopramide can block dopamine receptors as part of it’s mechanism of action.  I discuss the clinical implications from this in the podcast.

Metoclopramide can exacerbate Parkison’s disorder so you need to be careful in that type of patient.

Metoclopramide is dosed frequently, which can potentially be a downside as far as patient adherence goes.

Metoclopramide has a few potential interactions that you should be aware of.  I talk about those in this episode.

On this episode, I discuss the mechanism of action of the SGLT-2 Inhibitors and how they lower blood sugar.

These drugs are classically used for diabetes and eliminate blood sugar through the urine.

One of the potential side effects is that these drugs can increase the risk of genital infections and urinary tract infections.

There is a boxed warning on canagliflozin for its potential to increase the risk of amputation.

These drugs also have a mild diuretic type effect and can potentially cause hypotension.
