Vi-Atro (atropine / diphenoxylate) Disease Interactions

There are 24 disease interactions with Vi-Atro (atropine / diphenoxylate):

Major

Anticholinergics (Includes Vi-Atro) ↔ Autonomic Neuropathy

Severe Potential Hazard, High plausibility

Applies to: Autonomic Neuropathy

Agents with anticholinergic activity can exacerbate many of the manifestations of autonomic neuropathy, including tachycardia, anhidrosis, bladder atony, obstipation, dry mouth and eyes, cycloplegia and blurring of vision, and sexual impotence in males. Therapy with antimuscarinic agents and higher dosages of antispasmodic agents (e.g., dicyclomine or oxybutynin) should be administered cautiously in patients with autonomic neuropathy.

Anticholinergics (Includes Vi-Atro) ↔ Gi Obstruction

Severe Potential Hazard, High plausibility

Applies to: Esophageal Obstruction, Gastrointestinal Obstruction

Anticholinergics are contraindicated in patients with obstructive diseases such as achalasia, esophageal stricture or stenosis, pyloroduodenal stenosis, stenosing peptic ulcer, pyloric obstruction, and paralytic ileus. Anticholinergics may further suppress intestinal motility with resultant precipitation or aggravation of toxic megacolon.

Anticholinergics (Includes Vi-Atro) ↔ Glaucoma

Severe Potential Hazard, High plausibility

Applies to: Glaucoma/Intraocular Hypertension

Anticholinergic agents are contraindicated in patients with primary glaucoma, a tendency toward glaucoma (narrow anterior chamber angle), or adhesions (synechiae) between the iris and lens, as well as for the elderly and others in whom undiagnosed glaucoma or excessive pressure in the eye may be present. Because anticholinergics cause mydriasis, they may exacerbate these conditions.

Anticholinergics (Includes Vi-Atro) ↔ Obstructive Uropathy

Severe Potential Hazard, High plausibility

Applies to: Urinary Retention

In general, the use of anticholinergic agents is contraindicated in patients with urinary retention and bladder neck obstruction caused by prostatic hypertrophy. Dysuria may occur and may require catheterization. Also, anticholinergic drugs may aggravate partial obstructive uropathy. Caution is advised even when using agents with mild to moderate anticholinergic activity, particularly in elderly patients.

Major

Anticholinergics (Includes Vi-Atro) ↔ Reactive Airway Diseases

Severe Potential Hazard, Moderate plausibility

Applies to: Asthma

The use of systemic anticholinergics is contraindicated in the treatment of lower respiratory tract symptoms including asthma. Muscarinic receptor antagonists reduce bronchial secretions, which can result in decreased fluidity and increased thickening of secretions. However, ipratropium does not produce these effects and can be used safely in treating asthma.

Antimuscarinics (Includes Vi-Atro) ↔ Myasthenia Gravis

Severe Potential Hazard, Moderate plausibility

Applies to: Myasthenia Gravis

Because antimuscarinic agents have anticholinergic effects, they are contraindicated in patients with myasthenia gravis. Their use may be appropriate to reduce adverse muscarinic effects caused by an anticholinesterase agent.

Major

Antiperistaltic Agents (Includes Vi-Atro) ↔ Infectious Diarrhea

Severe Potential Hazard, High plausibility

Applies to: Infectious Diarrhea/Enterocolitis/Gastroenteritis, Infectious Diarrhea/Enterocolitis/Gastroenteritis

The use of drugs with antiperistaltic activity (primarily antidiarrheal and antimuscarinic agents, but also antispasmodic agents such as dicyclomine or oxybutynin at high dosages) is contraindicated in patients with diarrhea due to pseudomembranous enterocolitis or enterotoxin-producing bacteria. These drugs may prolong and/or worsen diarrhea associated with organisms that invade the intestinal mucosa, such as toxigenic E. coli, Salmonella and Shigella, and pseudomembranous colitis due to broad-spectrum antibiotics. Other symptoms and complications such as fever, shedding of organisms and extraintestinal illness may also be increased or prolonged. In general, because antiperistaltic agents decrease gastrointestinal motility, they may delay the excretion of infective gastroenteric organisms or toxins and should be used cautiously in patients with any infectious diarrhea, particularly if accompanied by high fever or pus or blood in the stool. Some cough and cold and other combination products may occasionally include antimuscarinic agents for their drying effects and may, therefore, require careful selection when necessary.

Major

Diphenoxylate (Includes Vi-Atro) ↔ Liver/Renal

Severe Potential Hazard, Moderate plausibility

Applies to: Hepatorenal Syndrome

Diphenoxylate should be used with extreme caution in patients with advanced hepatorenal disease and in all patients with abnormal liver function since hepatic coma may be precipitated. Diphenoxylate is contraindicated in patients with obstructive jaundice.

Major

Diphenoxylate (Includes Vi-Atro) ↔ Pseudomembranous Enterocolitis

Severe Potential Hazard, High plausibility

Applies to: Infectious Diarrhea/Enterocolitis/Gastroenteritis, Pseudomembranous Colitis

Antiperistaltic agents, such as diphenoxylate may prolong and/or worsen diarrhea associated with organisms that penetrate the intestinal mucosa and pseudomembranous enterocolitis associated with broad-spectrum antibiotics or enterotoxin-producing bacteria. Antiperistaltic agents should not be used in these conditions.

Moderate

Anticholinergics (Includes Vi-Atro) ↔ Cardiac Disease

Moderate Potential Hazard, Moderate plausibility

Applies to: Cardiovascular Disease

Anticholinergics block vagal inhibition of the SA nodal pacemaker. Therapy with anticholinergics should be administered cautiously to patients with tachycardia, congestive heart failure, or coronary artery disease. Premature ventricular depolarization, ventricular tachycardia, and fibrillation associated with anticholinergics are rare.

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
