Real Life Pharmacology - Pharmacology Education for Health Care Professionals
In this episode, I discuss loperamide (Imodium) pharmacology, adverse effects, and drug interactions. Loperamide has opioid-type activity in the gut but has extremely low oral bioavailability. This allows it to be used for diarrhea but at lower doses won't cause systemic opioid-like effects. Loperamide abuse has been reported. Excessive dosages can increase the risk of cardiac arrest and other cardiovascular concerns. Medication causes of diarrhea should be ruled out prior to starting a medication like loperamide. I discuss numerous medications that can cause diarrhea in this podcast.

Thank you David "Batman" Brown OMS IV for developing this podcast. Thank you Joshua Hansen, OMS III for joining us! This podcast reviews the problem of Loperamide misuse as an alternative to other opioids. This was a way of looking at how metabolism, excretion and transporter pumps might affect the medications we use. We enjoyed our discussion and hope you find it as interesting as we did! Thank you Jordan Turner for creating the perfect bumper music!
Guest: Tyler S. Oesterle, M.D., M.P.H. (@OesterleMD) Host: Darryl S. Chutka, M.D. (@ChutkaMD) Opioid abuse remains a significant problem, and as law enforcement and regulatory agencies tighten access to prescription analgesics, individuals are seeking alternatives. It's been discovered that when taken at very high doses, loperamide can produce similar effects to the opioid analgesics and the drug is inexpensive when compared to the price of both illicit and prescription opioids. As a result, loperamide abuse has become a significant problem. In this episode we discuss loperamide abuse with Tyler Oesterle, M.D., M.P.H., a psychiatrist at Mayo Clinic's Rochester campus. We'll review the typical central nervous system effects of high dose loperamide and the associated safety issues. Specific topics: Current status of the opioid crisis in the U.S. Effects of loperamide in both therapeutic and excessive doses Reasons behind taking high dose loperamide in excessive doses Safety issues associated with high dose loperamide Potential of high dose loperamide leading to drug dependence Connect with the Mayo Clinic's School of Continuous Professional Development online at https://ce.mayo.edu/ or on Twitter @MayoMedEd.

SHOW NOTES: Antihistamines: Like so many other over-the-counter medications, the dose of antihistamines makes the poison. Sedation is the most common side effect in antihistamine overdose. Some, like diphenhydramine, are more toxic and have profound anticholinergic effects. Sinus tachycardia is one of the first presentations, but remember the phrases: Tachy as a tie, dry as a bone, mad as a hatter, red as a beet, hot as a hare and blind as a bat. Excitatory toxidromes can be confusing, but urinary retention, impaired bowel motility and the absence of diaphoresis will differentiate anticholinergic toxicity from the other excitatory toxidromes. the higher the dose, the more side effects seen, leading to seizures and cardiac toxicity. Physostigmine is an antidote for anticholinergic toxicity. Delirium is the main indication for physostigmine, but it can also be given to prevent intubation and at times to get a more accurate history from the patient. Physostigmine lowers the seizure threshold, so benzodiazepines are usually given prior administration. Most likely they have already been given to treat undifferentiated delirium and excitation. Of note, physostigmine is not the cure all for the toxidrome because it has a very short half life. In the setting of seizures in overdose, very few anticonvulsants are safe. Benzodiazepines are some of the safer GABAergic agents. GABA is our main CNS inhibitory neurotransmitter, it essentially "tones down the nerves". Propofol and some other GABAergic agents can also help with tachycardia and hyperthermia. In these settings, benzodiazepines are given in very high doses. Diphenhydramine causes sodium channel blockade, subsequently decreasing action potential. lowering calcium in the cells, and causing life threatening myocardial depression. Calcium is given in this circumstance, but the mainstay of treatment is sodium bicarbonate. It works by increasing overall sodium availability and the pH. The more acidotic the patient, the more of the drug becomes unbound and available. At higher pH levels, the sodium channel blockade weakens, and more of the drug becomes protein bound. What about other antihistamines? While overdose of other antihistamines will be uncomfortable, the life threatening seizures and cardiac toxicity is unique to diphenhydramine. Acetaminophen: Acetaminophen is the highest nationally in morbidity and mortality of all drug overdoses. Most often taken on it's own, it's also mixed into many over-the-counter remedies. In the first 24-hours post-ingestion, the symptoms can be minimal. It's metabolized in the liver, and a small portion is metabolized by CIP 2E1, resulting in the toxic metabolite NAPQI. Normally, glutathione will detoxify NAPQI, but in acetaminophen overdose, glutathione stores are depleted and the excess NAPQI creates havoc in the liver. In a reliable historian with an acute ingestion, the Rumack-Matthew nomogram is employed, and will help guide antidote therapy. Serum acetaminophen levels will not be helpful until 4 hours post-ingestion, unless something that slows GI transit time and absorption has been taken as well. N-acetylcysteine or "NAC", is the antidote for Tylenol. If given within eight hours of ingestion it can prevent any liver toxicity. It can also be started any time a serious ingestion is suspected. Keep in mind, delayed-release Tylenol, certain populations, and conditions can obscure the diagnosis and in those settings the Rumack-Matthew nomogram can no longer be used. Chronic alcoholics who have just stopped drinking and malnourished patients are at higher risk of toxicity. Subacute and chronic ingestion is also very common. Essential lab tests include serum acetaminophen levels, ALT and AST, and INR. One would expect any or all of these to be elevated in significant toxicity. If they are, NAC is given intravenously for nearly 24 hours. NAC won't reverse hepatotoxicity that has already occurred, but will prevent more from happening. Dextromethorphan: Dextromethorphan, referred to sometimes as "robotripping" or "robo-frying". Taken in excess causes an individual to become disassociated. It is an NMDA antagonist, like ketamine, LSD and PCP. Expect to see the same clinical signs of serotonin excess, as well as dystonia. Patients can alternate dramatically between vacant blank stares, to incredibly violent outbursts. Patient and staff safety is a crucial element in treating this toxidrome. Rotatory nystagmus, a distinctive rapid "clock ticking" of the eyes is diagnostic of this type of ingestion. Loperamide: When Loperamide, an over-the-counter antidiarrheal, is used in abuse it can lead to death. It acts similar to opioids, slowing down the GI tract but without the central effects, because it is actively expelled from the CNS. In large doses, however, it delivers an opioid-like high. Loperamide can cause respiratory depression, but also persistent arrhythmias. The lethal effects are due to loperamide's potassium channel blocker properties causing profound QT prolongation, sinusoidal waves and can lead to cardiac arrest. Potassium channel blockade is difficult to treat. ACLS drugs, electrolyte normalization like magnesium infusions, and even Narcan can be given, but more than likely these incredibly sick patients will need ECMO. Ibuprofen: Ibuprofen is, overall, a safe drug. Large quantities of the drug have to be taken for toxic effects. If taking over 200mg/kg if Ibuprofen, a patient is likely to have some GI symptoms and possibly an acute kidney injury. treatment would include possible admission for antiemetics and IV fluids. Ibuprofen is metabolized as a propionic acid anion. If ore than 400mg/kg are taken, it will result in an anion gap metabolic acidosis. At over 600mg/kg, a whole constellation of symptoms results: seizures, hypotension, and cardiac shock. These patients are severely ill and may require ECMO for an extended period of time. At this dosage, a 100kg patient would need to take 300 pills. Which leads to the question, "How did they fit that many pills in their stomach?" Activated Charcoal: Finally, a note on activated charcoal. It works great for almost everything, except alcohol ingestion and metals, by binding drugs in the GI tract. Drug absorption is decreased by 60% if given within an hour. It should be avoided if the airway is compromised or if the patient is a risk for seizure. In an intubated patient with recent ingestion, it's given via nasogastric tube. Thank-you for listening.
Loperamide 2mg Hard Capsules are used to treat two types of diarrhea. The two types have different age limits for adults and children aged 12 and over to treat attacks that can last up to 48 hours.https://recoverypartnernetwork.com/drug/opioid/loperamide-abuse
Loperamide abuse has been on the rise within the past ten years. When high doses of the drug are consumed, it can produce effects similar to opioids. https://recoverypartnernetwork.com/drug/opioid/loperamide-abuse
Imodium overdose can lead to symptoms that scale from mild nausea and vomiting to problems with the liver and heart. The FDA has recently introduced a new Imodium warning label, alerting the users that taking a higher dose than recommended may cause cardiac arrhythmias or heart attacks.https://recoverypartnernetwork.com/drug/opioid/loperamide-abuse
Loperamide typically starts working within 1 hour to ease your diarrhea. Most people will have to take Loperamide only for 1 to 2 days but, you may need to take it for longer if you have diarrhea due to intestinal problems such as Crohn's disease, ulcerative colitis, or short bowel syndrome.https://recoverypartnernetwork.com/drug/opioid/loperamide-abuse
Loperamide is a very safe, non-addictive drug that can be taken at doses of up to 8 capsules (16 milligrams) per day over a long period of time. However, It is not advised to consume more than 16 milligrams a day without seeking medical advice.https://recoverypartnernetwork.com/drug/opioid/loperamide-abuse
Loperamide is usually administered once at the beginning of the treatment and then up to four times a day after each loose stool until the diarrhea is better. It must not be taken more often than every 3 hours or longer than two days.https://recoverypartnernetwork.com/drug/opioid/loperamide-abuse
In this episode, recorded just before the New Year, I discuss recent news in brain cancer research. This includes:How the drug loperamide (brand name Imodium), induces cell death in glioblastoma cell lines and if this could have promise for real, human applications. Metabolic reprogramming via inhibition of a key cancer metabolite- D-2-Hydroxyglutarate (D-2-HG).Developments of liquid biopsies for glioma.

Acute Gastroenteritis- Author: Dr. Brian Geyer Introduction: Do both vomiting and diarrhea have to be present? No 1996 AAP guidelines, 2016 ACG guidelines, and 2017 IDSA guidelines all note diarrhea illness but may be vomiting predominant. Studies use more vague definitions like: > 1 episode of vomiting and/or > 3 episodes of diarrhea in 24 hours without known chronic cause like inflammatory bowel disease. Diarrhea is at least 3 unformed stools per day. Acute episode 29 days Patients in the ED may present with only some of these symptoms depending their time in course of illness. Literature Review: There is abundant literature on pediatric AGE but sparse research on AGE in adults. Therefore, many recommendations are extrapolated from the pediatric literature. Causes: 70% of US cases are estimated to be caused by viruses, norovirus being most common. o 26% norovirus o 18% rotavirus Among bacterial causes: o 5.3% Salmonella, most common o 5.3% Clostridium o 3% Campylobacter o 3% parasitic infections Large portion, 51%, have no cause identified. (In ED patients) Interestingly, 79% of cases never have a cause identified (not ED specific) In ED patients, only 25% ever have a cause identified, this increases to 49% when a stool sample is obtained. (not ED specific) Food poisoning is responsible for 5% of AGE but results in 30% of deaths. Most commonly: Salmonella, Clostridium perfringens, and Campylobacter Majority of foodborne illness is still viral, mostly norovirus E Coli is normal in the gut, but two most common causes are: Shiga toxin Ecoli (STEC) AKA enterohemorrhagic Ecoli (EHEC) - causes Hemolytic Uremic Syndrome in 5-10% Entertoxigenic Ecoli (ETEC) - causes traveler's diarrhea Both cause self-limited illness. Alternate Diagnoses: Appendicitis: In the peds literature, misdiagnosis of appendicitis as AGE leads to 47% absolute increased risk of perforation. Suggestive findings include: Migration of pain to RLQ RLQ tenderness on exam (initial or repeat) Absence of diarrhea Pain not improved with episodes of diarrhea Negative factors include multiple ill family members, recent international travel, presence of diarrhea (as defined above). Ciguatera Fish Poisoning Toxin produced by algae consumed by reef fish like grouper, red snapper, sea bass and Spanish mackerel. Symptoms begin 6-24 hours post ingestion. Fish tastes normal. Patients may develop neurological symptoms like paresthesias, generalized pruritis, and reversal of hot/cold sensation. Symptoms resolve spontaneously, and treatment with mannitol is controversial. Scombroid Poisoning Ingesting fish in the Scombroidae family - mackerel, bonito, albacore, and skipjack - that have been stored improperly Bacteria produce histidine decarboxylase which converts histidine to histamine Causes abdominal cramps and diarrhea, and may cause metallic bitter or peppery taste in mouth, and facial flushing within 20-30 min of ingestion Can be confused with allergic reaction Symptoms resolve in 6-8 hours Notification of health dept may prevent others from being infected. Page 5 Table 1- Distinguishing Factors in the Differential Diagnosis of AGE History: Table 2, page 6 has key questions to ask. Onset, timing, number of stools, presence of blood, fever, quality of abdominal pain and location, recent antibiotics, etc. Extremes of age, immunosuppression, and pregnancy should be identified. Mortality is highest in the patients >65 yo. Physical Exam: We talked about RLQ abd pain, but what about bloody stool? An observational study of 889 adults and 151 pediatric with AGE showed that a negative fecal occult test showed accurately excluded invasive bacterial etiology with a NPV 87% in adults and 96% in children. But PPV was only 24%. Laboratory Testing and Imaging: Dehydration is the biggest contributor to mortality, especially in the very young and elderly. Lab evaluation for dehydration is recommended in these populations. No consistent association between lab abnormalities and bacterial etiology. WBC and differential does not differentiate bacterial vs viral, but may help in identifying severity of illness. Hemoglobin and platelets are helpful if HUS is suspected. Stool Cultures: 2017 IDSA guidelines recommends them in patients with fever, bloody or mucoid stools, severe abdominal cramping or tenderness, or signs of sepsis, noting these patients are at higher risk of bacterial infection. Specifically, Salmonella, shigella, Campylobacter, and Yersinia 2016 ACG guidelines recommend them for patients with watery diarrhea and moderate to severe illness with fever for at least 72 hours. Consider them for immunocompromised patients and those with recent abx use or hospitalization. C Difficile testing is recommended for all patients with AGE who are age >2 with a history of recent abx use or recent hospitalization Blood cultures are recommended for patients

Loperamide, an opiate agonist of high specificity for p-receptors, was recently reported to suppress ACTH and cortisol levels in normal subjects, but not in patients with proven ACTH-dependent Cushing’s disease. However, there is little information on the site of action of loperamide in the hypothalamo-pituitary-adrenal axis of man. We investigated the effect of loperamide on pituitary hormone secretion in uiuo and in vitro. In seven normal subjects, basal ACTH plasma levels were significantly suppressed 3 h after loperamide administration (16 mg, orally) from 5 + 1 to 2 f 0 pmol/L (P < 0.0001). After the combined pituitary stimulation test (100 pg human CRH, 100 rg GnRH, 100 pg GH-releasing hormone, and 200 pg TRH), the ACTH peak (maximum increase at 30 min) was significantly blunted by loperamide from 9 + 1 to 4 of: 1 pmol/L (P < 0.001) and the area under the curve of ACTH from O-120 min was reduced from 35 + 5 to 23 + 4 pmol/L.2 h (P < 0.05). In the insulin-hypoglycemia test (0.15 IU/kg BW), neither the ACTH peak nor the area under the curve of ACTH was affected by loperamide. In six patients with Cushing’s disease and one patient with secondary adrenal insufficency due to hypothalamic failure, neither basal ACTH and cortisol levels nor CRH-stimulated levels were influenced by loperamide. In four cultured human corticotropic adenomas, loperamide was not able to reduce basal and CRH-induced ACTH secretion. In summary, loperamide is able to reduce basal and CRHinduced ACTH and cortisol levels in normal subjects, but not in patients with Cushing’s disease or secondary adrenal failure of hypothalamic origin. Loperamide has no significant effect on insulin-hypoglycemia- induced ACTH and cortisol levels and, therefore, no effect on stress-induced elevation of cortisol levels. Loperamide might act at a suprapituitary site in man in viuo, but, nevertheless, a pituitary site cannot be excluded.
