Interactions between Gastrosed and Mitotane

The hyoscyamine in Gastrosed has a moderate potential interaction with Arrhythmia.

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

The hyoscyamine in Gastrosed has a moderate potential interaction with Arrhythmia.

Antimuscarinic agents block vagal inhibition of the SA nodal pacemaker. These agents should be administered cautiously in patients with tachycardia, congestive heart failure, or coronary artery disease. Premature ventricular depolarization or ventricular tachycardia or fibrillation associated with antimuscarinic drugs is rare.

The hyoscyamine in Gastrosed has a major potential interaction with 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.

The hyoscyamine in Gastrosed has a major potential interaction with 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.

The hyoscyamine in Gastrosed has a moderate potential interaction with Bleeding Disorder.

Antimuscarinic agents may cause a delay in gastric emptying and possibly antral stasis in patients with gastric ulcer. Therapy with antimuscarinic agents should be administered cautiously to patients with gastric ulcer.

The hyoscyamine in Gastrosed has a moderate potential interaction with Cardiovascular Conditions and Disorders.

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.

Mitotane has a moderate potential interaction with Depression.

Symptoms of depression consisting of lethargy and somnolence have been reported during mitotane therapy. Therapy with mitotane should be administered cautiously to patients with or predisposed to depression. Clinical monitoring of psychological behavior is recommended.

The hyoscyamine in Gastrosed has a minor potential interaction with Diarrhea.

Diarrhea may be a symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. Antimuscarinic agents may further aggravate the diarrhea. Therefore, these drugs should be administered cautiously in patients with diarrhea.

The hyoscyamine in Gastrosed has a major potential interaction with Esophageal 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.

The hyoscyamine in Gastrosed has a minor potential interaction with Fever.

Atropine-like agents may increase the risk of hyperthermia in patients with fever by producing anhidrosis. Therapy with atropine-like agents should be administered cautiously in febrile patients.

The hyoscyamine in Gastrosed has a major potential interaction with 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.

The hyoscyamine in Gastrosed has a moderate potential interaction with GERD.

Antimuscarinic agents decrease gastric motility and relax the lower esophageal sphincter which promotes gastric retention and can aggravate reflux. These drugs should be administered cautiously in patients with gastroesophageal reflux or hiatal hernia associated with reflux esophagitis.

The hyoscyamine in Gastrosed has a major potential interaction with 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.

The hyoscyamine in Gastrosed has a minor potential interaction with High Blood Pressure.

Cardiovascular effects of anticholinergics may exacerbate hypertension. Therapy with anticholinergic agents should be administered cautiously in patients with hypertension.

The hyoscyamine in Gastrosed has a minor potential interaction with Hyperthyroidism.

In general, agents with anticholinergic activity may exacerbate hyperthyroidism. Therapy with anticholinergics should be administered cautiously in patients with hyperthyroidism. Thyroid levels should be monitored if usage is prolonged.

Mitotane has a major potential interaction with Infection.

Mitotane inhibits production of corticosteroids and alters extra-adrenal metabolism of endogenous and exogenous steroids. All patients treated with mitotane should be instructed to immediately report signs and symptoms of infection or other illnesses. Therapy with mitotane should be withheld immediately following shock or severe trauma or infection. Exogenous steroids should be administered since the suppressed adrenal may not immediately begin to secrete steroids.

The hyoscyamine in Gastrosed has a major potential interaction with Infectious 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.

The hyoscyamine in Gastrosed has a moderate potential interaction with Ischemic Heart Disease.

Antimuscarinic agents block vagal inhibition of the SA nodal pacemaker. These agents should be administered cautiously in patients with tachycardia, congestive heart failure, or coronary artery disease. Premature ventricular depolarization or ventricular tachycardia or fibrillation associated with antimuscarinic drugs is rare.

The hyoscyamine in Gastrosed has a moderate potential interaction with Liver Disease.

Atropine-like agents undergo significant hepatic metabolism. Therapy with atropine-like agents should be administered cautiously to patients with liver disease.

Mitotane has a moderate potential interaction with Liver Disease.

Mitotane is primarily metabolized by the liver. Metabolism and therapeutic activity may be altered in patients with hepatic impairment. Therapy with mitotane should be administered cautiously in patients with hepatic impairment. Clinical monitoring of hepatic function is recommended.

Mitotane has a moderate potential interaction with Menopause.

Ovarian macrocysts, often bilateral and multiple, have been reported in premenopausal patients receiving mitotane which might lead to adnexal torsion and hemorrhagic cyst rupture. It is recommended to use care when using this agent in premenopausal patients and to seek medical care if they experience gynecological symptoms such as vaginal bleeding and/or pelvic pain.

The hyoscyamine in Gastrosed has a major potential interaction with 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.

Mitotane has a moderate potential interaction with Neurological Disorders.

Unspecified brain damage and impairment of function have been reported during prolonged mitotane therapy. Therapy with mitotane should be administered cautiously to patients with neurologic impairment. Clinical monitoring of behavior and neurological function is recommended when continuous mitotane therapy exceeds two years.

The hyoscyamine in Gastrosed has a moderate potential interaction with Renal Dysfunction.

Atropine-like agents are primarily eliminated by the kidney. Therapy with atropine-like agents should be administered cautiously to patients with renal disease.

Mitotane has a major potential interaction with Shock.

Mitotane inhibits production of corticosteroids and alters extra-adrenal metabolism of endogenous and exogenous steroids. All patients treated with mitotane should be instructed to immediately report signs and symptoms of infection or other illnesses. Therapy with mitotane should be withheld immediately following shock or severe trauma or infection. Exogenous steroids should be administered since the suppressed adrenal may not immediately begin to secrete steroids.

The hyoscyamine in Gastrosed has a moderate potential interaction with Ulcerative Colitis.

Antimuscarinic agents may suppress intestinal motility and produce paralytic ileus with resultant precipitation of toxic megacolon. These drugs should be administered cautiously to patients with ulcerative colitis.

The hyoscyamine in Gastrosed has a major potential interaction with 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.
