Leflunomide Pharmacology

leflunomide pharmacology

On this episode, I discuss leflunomide pharmacology. It is classified as a DMARD and is primarily used in rheumatoid arthritis.

Leflunomide carries a boxed warning for hepatoxicity. LFTs must be monitored with its use.

Leflunomide can inhibit CYP2C8 which plays an important role in pioglitazone metabolism. Concentrations of pioglitazone can go up on account of this interaction.

TB screening should be done prior to beginning the immunosuppressant leflunomide.

Baclofen Pharmacology

Baclofen is primarily used for its ability to help relieve muscle spasms. I discuss baclofen pharmacology on this podcast episode.

Baclofen should not be abruptly discontinued as it can cause a significant withdrawal reaction whose symptoms may include fever, spasticity, rhabdomyolysis, and death.

While baclofen generally avoids any issues with CYP enzyme interactions, it is eliminated by the kidney. Renal function changes can alter drug concentrations.

Sedation, confusion, dizziness, hypotension, and GI upset are some of the more common adverse effects of baclofen.

Bromocriptine Pharmacology

bromocriptine pharmacology

On this episode, I discuss bromocriptine pharmacology. It is a dopamine agonist that can be used for hyperprolactinemia and Parkinson’s symptoms.

One of the major side effects of bromocriptine is nausea which stems from its dopamine agonist action.

Because bromocriptine is a dopamine agonist, it can counteract the action of antipsychotics.

Bromocriptine is broken down by CYP3A4, so drug interactions can be common. Erythromycin, some of the azole antifungals, verapamil, grapefruit juice, and diltiazem are all medications that can increase concentrations.

Tacrolimus Pharmacology

On this episode, I discuss tacrolimus pharmacology. This medication is an immunosuppressant used to reduce the risk of transplant rejection.

Tacrolimus has a long list of potential adverse effects such as hyperglycemia, renal impairment, GI toxicity, and hypertriglyceridemia.

Important monitoring parameters for tacrolimus include drug levels, electrolytes, renal function, and blood sugars.

CYP3A4 interactions are critical with tacrolimus. Inhibitors can raise concentrations and inducers can lower concentrations.

Ibuprofen Pharmacology

ibuprofen pharmacology

On this episode of the Real Life Pharmacology Podcast, I discuss ibuprofen pharmacology.

Ibuprofen can raise the concentrations of lithium and increase the risk for toxicity.

Compared to most other NSAIDs, ibuprofen has a relatively short half-life. This explains why it needs to be dosed more frequently than other agents.

Ibuprofen can contribute to renal insufficiency, GI bleed risk, and CHF exacerbations.

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.

Escitalopram Pharmacology

escitalopram pharmacology

On this episode of the Real Life Pharmacology Podcast, I discuss escitalopram pharmacology.

Escitalopram is an SSRI and can be used to manage depression, anxiety, OCD, PTSD, and other psychiatric disorders.

If you consider fluoxetine the most activation SSRI and paroxetine the most sedating, escitalopram probably falls somewhere in the middle.

Sexual dysfunction is a potential adverse effect with escitalopram. I discuss it further on this episode.

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.

Tiotropium Pharmacology

On this episode, I discuss tiotropium pharmacology. In addition, I cover adverse effects, administration pearls, and drug interactions.

Tiotropium blocks acetylcholine from binding the M3 receptor in the lungs. This leads to a relaxation of the bronchial smooth muscle.

Because tiotropium has anticholinergic activity, there is a potential for anticholinergic adverse effects like constipation, urinary retention, and dry mouth.

The tiotropium Handihaler can be confusing to patients. I discuss medication misadventures in this podcast episode.

Palivizumab Pharmacology

On this episode, I discuss palivizumab pharmacology and how it is used in pediatric patients.

Palivizumab is a monoclonal antibody that is used to prevent RSV infections in pediatric patients.

Palivizumab is an IM injection that is dosed by weight. Learn more on this podcast episode.

RSV can be devastating in pediatric patients under the age of two. Palivizumab can be used in select populations to help prevent the infection.

Injection and skin reactions are possible with the use of palivizumab.
