Actions and Spectrum: 

diphenoxylate/atropine is a combination medication used to treat diarrhea. It works by slowing down the movement of the intestines, which reduces the frequency and urgency of bowel movements and helps to relieve diarrhea symptoms. The medication contains two active ingredients: diphenoxylate and atropine. 

diphenoxylate is an opioid agonist that acts on the mu-opioid receptors in the gastrointestinal tract. It works by slowing down the motility of the intestines, reducing the amount of fluid and electrolytes lost through the bowel movements, and improving the consistency of stools. diphenoxylate is structurally like the narcotic pain medication meperidine (Demerol) but has a much lower potential for abuse. 

atropine is added to the formulation to discourage misuse of diphenoxylate, as it can cause unpleasant side effects such as dry mouth, blurred vision, and urinary retention. Atropine also has some antidiarrheal effects on its own, as it reduces intestinal motility and secretions and can help to relieve cramps and spasms. 

The combination of diphenoxylate and atropine has a broad spectrum of activity against different types of diarrhea, including acute and chronic diarrhea caused by infectious, inflammatory, or functional disorders. However, it is not recommended for use in patients with bacterial infections or other specific causes of diarrhea, as it may interfere with the elimination of the infectious agent and delay the resolution of the infection.

Diphenoxylate/atropine is contraindicated in children under 6 years of age due to the risk of respiratory depression, coma, and death, especially when overdosed. Extreme caution must be used when administering this medication to pediatric patients, and it should never be used in children under the age of 2. Use only the lowest effective dose for the shortest possible duration to minimize the risk of serious adverse effects. 

Contraindication/Caution: 

Allergy or hypersensitivity to diphenoxylate, atropine, or any of the ingredients in the formulation. 

  • Severe liver disease or hepatic encephalopathy, as the medication may worsen these conditions. 
  • Infectious diarrhea caused by bacteria, viruses, or parasites, as the medication may slow down the elimination of the infectious agent and delay the resolution of the infection. 
  • Glaucoma or other eye conditions that can be worsened by the anticholinergic effects of atropine. 
  • Respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), as the medication may cause respiratory depression or worsen these conditions. 
  • Pregnancy or breastfeeding, as the safety and efficacy of the medication have not been established in these populations. 

Caution should also be exercised when using diphenoxylate/atropine in patients with certain medical conditions, such as inflammatory bowel disease, kidney disease, or heart disease, as well as in patients taking other medications that may interact with diphenoxylate/atropine. The medication may cause drowsiness, dizziness, or impaired coordination, so patients should avoid driving or operating heavy machinery until they know how the medication affects them. 

Pregnancy consideration: diphenoxylate/atropine should be used in pregnancy only if the assumed benefits outweigh potential risks 

Breastfeeding warnings: Some of the active metabolites of the diphenoxylate are secreted in breastmilk but are unknown for atropine 

Hence consult your physician for the same 

Pregnancy category: 

  • Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester. 
  • Category B: There is no affirmation of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women. 
  • Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a product in humans; Pregnant women must take care of the potential risks. 
  • Category D: There is adequate data available with sufficient evidence of human fetal risk from various platforms. However, despite potential dangers may be used only in emergency cases for potential benefits. 
  • Category X: Drugs listed in this category outweigh risks over benefits. The drug is not for pregnant women. 
  • Category N: No data is available for the drug under this category. 

Pharmacology: 

diphenoxylate/atropine is a combination medication used for the treatment of diarrhea. diphenoxylate is an opioid medication that works by slowing down the movement of the intestines and reducing the frequency and volume of bowel movements. Atropine is added to the medication to discourage abuse of diphenoxylate, which can be addictive if taken in large amounts. 

Pharmacodynamics: 

diphenoxylate is a synthetic opioid agonist that binds to the mu-opioid receptors in the gastrointestinal tract, which slows down the propulsive contractions of the smooth muscle and reduces the secretions in the intestinal tract. This results in reduced peristalsis and increased transit time, which leads to decreased frequency and volume of bowel movements. 

atropine is an antimuscarinic agent that works by blocking the action of acetylcholine at muscarinic receptors in the gastrointestinal tract. atropine inhibits the secretions in the intestinal tract and reduces smooth muscle contractions, which results in a further decrease in bowel movement frequency and volume. 

Pharmacokinetics: 

diphenoxylate is absorbed slowly and incompletely from the gastrointestinal tract. The drug is metabolized in the liver, primarily by glucuronidation, and the metabolites are excreted in the urine. 

atropine is rapidly absorbed from the gastrointestinal tract and is widely distributed throughout the body. The drug is metabolized in the liver and excreted primarily in the urine. 

Administration: 

diphenoxylate/atropine is available as a tablet and is typically taken orally. The recommended dose for adults is 2 tablets (2.5 mg diphenoxylate/0.025 mg atropine per tablet) four times a day or as directed by a healthcare provider. The medication should be taken with a full glass of water. 

It is important to follow the dosing instructions provided by the healthcare provider and not exceed the recommended dose. Diphenoxylate has the potential for abuse and addiction, and taking more than the recommended dose or taking it for longer than prescribed can lead to dependence. 

Patients should not take diphenoxylate/atropine for more than 48 hours without consulting a healthcare provider. If symptoms persist or worsen after 48 hours of treatment, a healthcare provider should be consulted to rule out underlying conditions. Patients should also avoid alcohol while taking diphenoxylate/atropine, as alcohol can increase the sedative effects of the medication. 

In addition to taking diphenoxylate/atropine as directed, patients should also maintain good hydration by drinking plenty of fluids to replace those lost due to diarrhea. Electrolyte replacement solutions may also be recommended in severe cases of diarrhea.

Pronounced: dahy-fen-ok-suh-leyt -atruh-peen 

Why do we use diphenoxylate/atropine? 

diphenoxylate/atropine is used to treat acute or chronic diarrhea in adults. It is a combination medication that contains diphenoxylate, an opioid medication that slows down the movement of the intestines and reduces the frequency and volume of bowel movements, and atropine, which is added to the medication to discourage its abuse. 

Diarrhea can result from a variety of causes, including infections, medications, and digestive disorders. The goal of treatment is to reduce the frequency and volume of bowel movements and to alleviate associated symptoms such as cramping, abdominal pain, and dehydration. 

diphenoxylate/atropine can help to slow down the movement of the intestines and reduce the volume and frequency of bowel movements, thereby helping to alleviate the symptoms of diarrhea. atropine is added to the medication to discourage its abuse, as diphenoxylate can be addictive if taken in large amounts.

Actions and Spectrum: 

diphenoxylate/atropine is a combination medication used to treat diarrhea. It works by slowing down the movement of the intestines, which reduces the frequency and urgency of bowel movements and helps to relieve diarrhea symptoms. The medication contains two active ingredients: diphenoxylate and atropine. 

diphenoxylate is an opioid agonist that acts on the mu-opioid receptors in the gastrointestinal tract. It works by slowing down the motility of the intestines, reducing the amount of fluid and electrolytes lost through the bowel movements, and improving the consistency of stools. diphenoxylate is structurally like the narcotic pain medication meperidine (Demerol) but has a much lower potential for abuse. 

atropine is added to the formulation to discourage misuse of diphenoxylate, as it can cause unpleasant side effects such as dry mouth, blurred vision, and urinary retention. Atropine also has some antidiarrheal effects on its own, as it reduces intestinal motility and secretions and can help to relieve cramps and spasms. 

The combination of diphenoxylate and atropine has a broad spectrum of activity against different types of diarrhea, including acute and chronic diarrhea caused by infectious, inflammatory, or functional disorders. However, it is not recommended for use in patients with bacterial infections or other specific causes of diarrhea, as it may interfere with the elimination of the infectious agent and delay the resolution of the infection.

Diphenoxylate/atropine is contraindicated in children under 6 years of age due to the risk of respiratory depression, coma, and death, especially when overdosed. Extreme caution must be used when administering this medication to pediatric patients, and it should never be used in children under the age of 2. Use only the lowest effective dose for the shortest possible duration to minimize the risk of serious adverse effects. 

Contraindication/Caution: 

Allergy or hypersensitivity to diphenoxylate, atropine, or any of the ingredients in the formulation. 

  • Severe liver disease or hepatic encephalopathy, as the medication may worsen these conditions. 
  • Infectious diarrhea caused by bacteria, viruses, or parasites, as the medication may slow down the elimination of the infectious agent and delay the resolution of the infection. 
  • Glaucoma or other eye conditions that can be worsened by the anticholinergic effects of atropine. 
  • Respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), as the medication may cause respiratory depression or worsen these conditions. 
  • Pregnancy or breastfeeding, as the safety and efficacy of the medication have not been established in these populations. 

Caution should also be exercised when using diphenoxylate/atropine in patients with certain medical conditions, such as inflammatory bowel disease, kidney disease, or heart disease, as well as in patients taking other medications that may interact with diphenoxylate/atropine. The medication may cause drowsiness, dizziness, or impaired coordination, so patients should avoid driving or operating heavy machinery until they know how the medication affects them. 

Pregnancy consideration: diphenoxylate/atropine should be used in pregnancy only if the assumed benefits outweigh potential risks 

Breastfeeding warnings: Some of the active metabolites of the diphenoxylate are secreted in breastmilk but are unknown for atropine 

Hence consult your physician for the same 

Pregnancy category: 

  • Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester. 
  • Category B: There is no affirmation of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women. 
  • Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a product in humans; Pregnant women must take care of the potential risks. 
  • Category D: There is adequate data available with sufficient evidence of human fetal risk from various platforms. However, despite potential dangers may be used only in emergency cases for potential benefits. 
  • Category X: Drugs listed in this category outweigh risks over benefits. The drug is not for pregnant women. 
  • Category N: No data is available for the drug under this category. 

Pharmacology: 

diphenoxylate/atropine is a combination medication used for the treatment of diarrhea. diphenoxylate is an opioid medication that works by slowing down the movement of the intestines and reducing the frequency and volume of bowel movements. Atropine is added to the medication to discourage abuse of diphenoxylate, which can be addictive if taken in large amounts. 

Pharmacodynamics: 

diphenoxylate is a synthetic opioid agonist that binds to the mu-opioid receptors in the gastrointestinal tract, which slows down the propulsive contractions of the smooth muscle and reduces the secretions in the intestinal tract. This results in reduced peristalsis and increased transit time, which leads to decreased frequency and volume of bowel movements. 

atropine is an antimuscarinic agent that works by blocking the action of acetylcholine at muscarinic receptors in the gastrointestinal tract. atropine inhibits the secretions in the intestinal tract and reduces smooth muscle contractions, which results in a further decrease in bowel movement frequency and volume. 

Pharmacokinetics: 

diphenoxylate is absorbed slowly and incompletely from the gastrointestinal tract. The drug is metabolized in the liver, primarily by glucuronidation, and the metabolites are excreted in the urine. 

atropine is rapidly absorbed from the gastrointestinal tract and is widely distributed throughout the body. The drug is metabolized in the liver and excreted primarily in the urine. 

Administration: 

diphenoxylate/atropine is available as a tablet and is typically taken orally. The recommended dose for adults is 2 tablets (2.5 mg diphenoxylate/0.025 mg atropine per tablet) four times a day or as directed by a healthcare provider. The medication should be taken with a full glass of water. 

It is important to follow the dosing instructions provided by the healthcare provider and not exceed the recommended dose. Diphenoxylate has the potential for abuse and addiction, and taking more than the recommended dose or taking it for longer than prescribed can lead to dependence. 

Patients should not take diphenoxylate/atropine for more than 48 hours without consulting a healthcare provider. If symptoms persist or worsen after 48 hours of treatment, a healthcare provider should be consulted to rule out underlying conditions. Patients should also avoid alcohol while taking diphenoxylate/atropine, as alcohol can increase the sedative effects of the medication. 

In addition to taking diphenoxylate/atropine as directed, patients should also maintain good hydration by drinking plenty of fluids to replace those lost due to diarrhea. Electrolyte replacement solutions may also be recommended in severe cases of diarrhea.

Why do we use diphenoxylate/atropine? 

diphenoxylate/atropine is used to treat acute or chronic diarrhea in adults. It is a combination medication that contains diphenoxylate, an opioid medication that slows down the movement of the intestines and reduces the frequency and volume of bowel movements, and atropine, which is added to the medication to discourage its abuse. 

Diarrhea can result from a variety of causes, including infections, medications, and digestive disorders. The goal of treatment is to reduce the frequency and volume of bowel movements and to alleviate associated symptoms such as cramping, abdominal pain, and dehydration. 

diphenoxylate/atropine can help to slow down the movement of the intestines and reduce the volume and frequency of bowel movements, thereby helping to alleviate the symptoms of diarrhea. atropine is added to the medication to discourage its abuse, as diphenoxylate can be addictive if taken in large amounts.
