Naltrexone Pharmacology Podcast – Episode 307

In this podcast episode, I discuss naltrexone pharmacology, adverse effects, drug interactions, and much more.

Naltrexone is an opioid antagonist and can blunt the effects of opioid agonists. Because of this, the medication can be used to manage opioid use disorder.

Hepatotoxicity is a concern of naltrexone and because of this, it is recommended to monitor LFTs.

There is an injectable, long-acting formulation of naltrexone that can be used for opioid and alcohol use disorder treatment.

Acamprosate Pharmacology Podcast – Episode 306

On this podcast episode, I discuss acamprosate pharmacology, adverse effects, drug interactions, and much more!

Acamprosate’s most common adverse effect is diarrhea. It is a primary reason why patients will ask to stop taking this medication.

It is critical to assess renal function prior to using acamprosate. Dose adjustments are recommended when patients have a CrCl of less than 50 ml/min.

Unlike naltrexone, acamprosate avoids liver metabolism making it an alternative option in alcohol use disorder for patients who have liver impairment.

Guanfacine Pharmacology Podcast

On this episode of the podcast, I cover guanfacine pharmacology, adverse effects, drug interactions, and much more.

Guanfacine is a central acting alpha-2 agonist that has the brand names of Tenex and Intuniv.

Because of guanfacine’s mechanism of action, it suppresses the sympathetic response leading to a drop in pulse and blood pressure.

It is important to remind patients that the onset of action is slow in the management of ADHD with guanfacine. I discuss this further in this podcast episode.

Risperidone Pharmacology Podcast

On this episode, I discuss risperidone pharmacology, adverse effects, monitoring, and common indications.

There are numerous drug interactions that I discuss in this podcast episode. CYP2D6 inhibitors may increase drug concentrations.

Risperidone increases prolactin more than most 2nd generation antipsychotics. This can lead to sexual adverse effects.

QTC prolongation is a concern with all antipsychotics like risperidone. We can monitor EKG to monitor for this risk.

Vortioxetine Pharmacology Podcast

On this podcast episode, I discuss vortioxetine pharmacology, adverse effects, drug interactions, and much more.

Because of vortioxetine’s long half-life, antidepressant discontinuation syndrome is going to be less prominent compared to ADPs with shorter half-lives.

Vortioxetine is metabolized by CYP2D6. Drugs that inhibit this enzyme will likely raise concentrations and place the patient more at risk for adverse effects.

I discuss rare vortioxetine adverse effects like hyponatremia and bleeding in this podcast episode.

Ramelteon (Rozerem) Pharmacology Podcast

On this episode, I discuss the pharmacology, adverse effects, and drug interactions of ramelteon (Rozerem).

Ramelteon is primarily only helpful for sleep onset and generally is not that helpful in sleep maintenance.

CNS depressant drug interactions will be a common concern to monitor. Opioids, benzodiazepines, and alcohol are common sedatives that can add to the effects of ramelteon.

Some of the CYP enzymes break down Ramelteon. I discuss this in greater length in this podcast episode.
