Opioid Use Disorder Medications

Abdominal cramping and intestinal spasms are common complaints in patients with conditions such as irritable bowel syndrome (IBS). Two of the most frequently prescribed medications for these symptoms are dicyclomine and hyoscyamine. These medications work by blocking muscarinic receptors, reducing smooth muscle contractions in the gastrointestinal tract and helping relieve painful spasms. While these medications can be effective, they are not without risks. Because of their anticholinergic effects, patients may experience dry mouth, constipation, blurred vision, dizziness, and urinary retention. Older adults are particularly susceptible to these adverse effects, making careful patient selection and monitoring especially important. Patients with benign prostatic hyperplasia (BPH), glaucoma, or cognitive impairment may be at higher risk for complications. In this episode of the Real Life Pharmacology podcast, we’ll review how dicyclomine and hyoscyamine work, discuss their most common clinical uses, compare their adverse effect profiles, and highlight practical education points to help optimize safe and effective use.

Heartburn is one of the most common gastrointestinal complaints, and antacids remain a go-to option for fast symptom relief. In this episode, we’ll discuss how common antacids like calcium carbonate, magnesium hydroxide, aluminum hydroxide, and sodium bicarbonate work to neutralize stomach acid. We’ll also review their advantages, common adverse effects, important drug interactions, and considerations for patients with kidney disease. Whether you’re a healthcare professional looking for practical clinical pearls or simply want to better understand over-the-counter heartburn medications, this episode provides a concise overview of when antacids are appropriate—and when they may not be the best choice.

Gastroparesis can be a frustrating condition for both patients and clinicians, with symptoms such as nausea, vomiting, early satiety, bloating, and poor glycemic control significantly affecting quality of life. Medication management often requires balancing effectiveness with safety, especially since many commonly prescribed drugs can either improve or worsen gastric emptying. In this episode of the Real Life Pharmacology podcast, we’ll review the medications used to treat gastroparesis, discuss their mechanisms of action, highlight important adverse effects, and identify medications that may contribute to or exacerbate delayed gastric emptying.

H2 blockers may not receive as much attention as proton pump inhibitors, but they continue to play an important role in managing acid-related disorders. In this episode of the Real Life Pharmacology podcast, we’ll review how H2 blockers work, compare the available agents, discuss important adverse effects, renal dose adjustments, drug interactions, and identify the patients who are most likely to benefit from these medications. Whether you’re a pharmacist, nurse, pharmacy technician, physician, or student, this episode provides practical clinical pearls you can apply immediately to patient care. In this episode, I also discuss a new podcast I discovered – go check out the Mechanism of Action Podcast! It is an entertaining and educational look at how many of the medications used today were discovered and derived.

Proton pump inhibitors (PPIs) are among the most commonly prescribed medications, but understanding how they work is essential for using them safely and effectively. In this episode of the Real Life Pharmacology podcast, we’ll break down the pharmacology of PPIs, including their mechanism of action, common brand and generic names, clinical uses, adverse effects, drug interactions, and important monitoring considerations. Whether you’re a pharmacist, nurse, pharmacy technician, or student, this episode will help reinforce the key concepts you need to confidently apply PPI pharmacology in clinical practice.

Naltrexone is often a first-line medication for AUD. It works as an opioid receptor antagonist, reducing the rewarding effects of alcohol and decreasing cravings. Patients frequently report that alcohol becomes less pleasurable while taking the medication. Oral naltrexone is typically dosed at 50 mg daily, while a long-acting injectable formulation is also available. Avoid use in patients taking opioids and use caution in significant liver dysfunction. Acamprosate helps maintain abstinence by modulating glutamate and GABA neurotransmission. Chronic alcohol use disrupts the balance between excitatory and inhibitory pathways in the brain, and acamprosate helps restore equilibrium. It is primarily eliminated renally, making it a useful option in patients with liver disease. The most common adverse effect is diarrhea. Disulfiram works through a completely different mechanism. It inhibits aldehyde dehydrogenase, causing acetaldehyde accumulation when alcohol is consumed. This can lead to flushing, nausea, vomiting, headache, and hypotension. Because of this aversive reaction, patient motivation and adherence are critical for success. Be sure to check out our free Top 200 study guide – a 31 page PDF that is yours for FREE!

In this episode, we explore monoamine oxidase inhibitors (MAOIs), one of the oldest yet most effective classes of antidepressants. We discuss how MAOIs such as phenelzine, tranylcypromine, isocarboxazid, and selegiline work by increasing serotonin, norepinephrine, and dopamine levels in the brain. The episode reviews their unique role in treatment-resistant and atypical depression, key adverse effects, important dietary considerations involving tyramine-containing foods, and potentially serious drug interactions. We also highlight practical clinical pearls to help pharmacists and healthcare professionals safely and effectively use these powerful but often underutilized medications.

In this episode, we explore four unique antidepressants that do not fit neatly into the traditional SSRI or SNRI categories: trazodone, nefazodone, vilazodone, and vortioxetine. Trazodone and nefazodone are classified as serotonin antagonist and reuptake inhibitors (SARIs), working primarily through blockade of 5-HT2 receptors while also inhibiting serotonin reuptake. Trazodone’s strong antihistamine and alpha-1 blocking properties make it highly sedating and commonly used off-label for insomnia, whereas nefazodone causes less sedation but is rarely prescribed today because of its association with severe and potentially fatal liver toxicity. Both agents are notable for producing less sexual dysfunction than many traditional SSRIs. We also discuss two newer multimodal antidepressants: vilazodone (Viibryd) and vortioxetine (Trintellix). Vilazodone combines serotonin reuptake inhibition with partial agonism at the 5-HT1A receptor, a mechanism often compared to combining an SSRI with buspirone. Vortioxetine has an even more complex pharmacology, acting as a serotonin reuptake inhibitor while modulating multiple serotonin receptor subtypes through agonist, partial agonist, and antagonist actions. This multimodal activity may contribute to benefits in cognitive symptoms associated with major depressive disorder. Throughout the episode, we compare receptor pharmacology, clinical applications, adverse effect profiles, and the unique characteristics that distinguish these medications from more commonly prescribed antidepressants.
