Brexpiprazole (Rexulti) Pharmacology Podcast

Brexpiprazole (Rexulti) is a second generation antipsychotic. I discuss its pharmacology, adverse effects, drug interactions, and more in this podcast episode.

I like to associate brexpiprazole with aripiprazole. They have a lot of overlapping characteristics, particularly in relation to the adverse effect profile.

Brexpiprazole tends to have a low incidence of metabolic adverse effects which makes it a nice selection for patients who have diabetes, hypercholesterolemia, or who are overweight.

CYP3A4 and CYP2D6 are the two primary enzymes that break down brexpiprazole. I discuss the pharmacogenomic considerations associated with this medication.

Lurasidone Pharmacology

On this podcast episode, I discuss lurasidone pharmacology, adverse effects, and drug interactions.

CYP3A4 is an important enzyme in the breakdown of lurasidone. I discuss this further on this episode.

Lurasidone is best taken with food as this enhances absorption and helps improve drug concentrations.

Lurasidone tends to have a lower risk for metabolic syndrome compared to other antipsychotics which is a nice advantage.

Cabergoline Pharmacology

Cabergoline is a dopamine agonist. I discuss the pharmacology, adverse effects, and drug interactions in this podcast episode.

Be on the lookout for drugs that could oppose the effects of cabergoline such as antipsychotics and metoclopramide.

Cabergoline can be used for hyperprolactinemia management and may cause adverse effects like hypotension and GI upset.

Cabergoline has a very long half-life so it is most often only dosed 1-2 times per week.

Trihexyphenidyl (Artane) Pharmacology

On this episode, I breakdown trihexyphenidyl (Artane) pharmacology, adverse effects, and drug interactions.

Trihexyphenidyl is highly anticholinergic and can cause constipation, dry eyes, dry mouth, and urinary retention.

Dementia medications like donepezil can have their effects blunted by the use of trihexyphenidyl.

Trihexyphenidyl is an older anticholinergic that is rarely used for the management of EPS caused by antipsychotics.

Aripiprazole Pharmacology

aripiprazole pharmacology

Aripiprazole is metabolized by CYP2D6 and CYP3A4. Because of this, drug interactions can happen. I discuss specific examples in this episode.

Partial dopamine agonist activity and serotonergic activity make up a significant amount of aripiprazole’s pharmacology.

Aripiprazole is classified as an antipsychotic and can be used in schizophrenia, bipolar disorder, and depression augmentation.

Aripiprazole can cause significant akathesia. I discuss this adverse effect on this episode.

I discuss important drug interactions on the podcast, be sure to check out my latest project which is a 200+ page book on managing drug interactions in primary care.

Ziprasidone Pharmacology

ziprasidone pharmacology

On this episode of the Real Life Pharmacology Podcast, I cover ziprasidone pharmacology.

Ziprasidone has dopamine blocking activity and is classified as a second generation antipsychotic.

Ziprasidone tends to have lower metabolic syndrome risks compared to other antipsychotics like clozapine and olanzapine.

QTc prolongation is a significant risk with ziprasidone and be aware of drug interactions and electrolyte imbalances that may increase this risk.

I discuss important drug interactions on the podcast, be sure to check out my latest project which is a 200+ page book on managing drug interactions in primary care.

Olanzapine Pharmacology

Olanzapine is a 2nd generation antipsychotic that blocks dopamine-2 receptors.

Olanzapine Relprevv (long acting injectable) needs to be closely monitored after the injection is given due to risks of sedation and delirium.

Sedation is a common occurance with the use of olanzapine. It is one of the more sedating second generation antipsychotics.

Weight gain, hyperlipidemia, and hyperglycemia are all potential adverse effects with olanzapine.

Benztropine Pharmacology

Benztropine Pharmacology

Benztropine is a highly anticholinergic medication that is primarily used for movement disorders.

Antipsychotics can cause extrapyramidal adverse effects that can help be managed with benztropine.

Because benztropine is highly anticholinergic, it can cause dry eyes, dry mouth, urinary retention, constipation and contribute to falls and confusion, particularly in our elderly population.

While benztropine is classified as an anti-Parkinson’s agent, it is rarely used for that indication as it has a high incidence of anticholinergic adverse effects (particularly at the doses that are required for benefit).

Clozapine Pharmacology

Clozapine Pharmacology

On this episode, I discuss clozapine pharmacology. This drug has multiple mechanisms of action: Dopamine blockade, anticholinergic activity, and alpha blocking activity all contribute to the complexity of this drug.

Smoking cessation can significantly increase the concentrations of clozapine. This is because smoking can induce CYP1A2. Listen to the podcast for more details on how this can impact our patients clinically.

Clozapine has 5 boxed warnings. I discuss them all in this podcast. The most well-known boxed warning is for agranulocytosis.

Because clozapine has alpha blocking activity, it can cause orthostasis. We need to monitor for this.

Clozapine can cause QTc prolongation. Keep an eye out for other medications that the patient may be taking that can also cause this. Examples include: amiodarone, ondansetron, quinolones, and macrolides
