Interactions between Procyclidine and Slow-K

The potassium chloride in Slow-K has a major potential interaction with Acidosis.

The use of potassium salts is contraindicated in patients with hyperkalemia, since a further increase in serum potassium concentration in such patients can lead to cardiac arrhythmias or arrest. Potassium therapy should be administered cautiously in patients with conditions predisposing to hyperkalemia, such as chronic renal failure, systemic acidosis, acute dehydration, hypoaldosteronism (e.g., due to primary adrenal insufficiency or congenital adrenal enzyme deficiency), uncontrolled diabetes mellitus, and extensive tissue breakdown (e.g., due to severe burns, intravascular hemolysis, tumor lysis syndrome, or rhabdomyolysis). Close monitoring of serum potassium concentrations is recommended, as potentially fatal hyperkalemia can develop rapidly and is often asymptomatic, manifested only by an increased potassium level (6.5 to 8 mEq/L) and characteristic electrocardiographic changes (peaking of T waves, loss of P waves, depression of ST segment, prolongation of the QT interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9 to 12 mEq/L). Continuous or serial electrocardiography may be appropriate in some patients during replacement therapy, particularly if given intravenously.

The potassium chloride in Slow-K has a moderate potential interaction with Acidosis.

Hypokalemia in patients with metabolic acidosis should be treated with an alkalinizing potassium salt (i.e. acetate, bicarbonate, citrate, or gluconate) rather than potassium chloride, since alkali therapy helps to promote cellular uptake of potassium. Close monitoring of acid-base balance, serum electrolytes, electrocardiogram, and clinical status is recommended.

The potassium chloride in Slow-K has a major potential interaction with Adrenal Insufficiency.

The use of potassium salts is contraindicated in patients with hyperkalemia, since a further increase in serum potassium concentration in such patients can lead to cardiac arrhythmias or arrest. Potassium therapy should be administered cautiously in patients with conditions predisposing to hyperkalemia, such as chronic renal failure, systemic acidosis, acute dehydration, hypoaldosteronism (e.g., due to primary adrenal insufficiency or congenital adrenal enzyme deficiency), uncontrolled diabetes mellitus, and extensive tissue breakdown (e.g., due to severe burns, intravascular hemolysis, tumor lysis syndrome, or rhabdomyolysis). Close monitoring of serum potassium concentrations is recommended, as potentially fatal hyperkalemia can develop rapidly and is often asymptomatic, manifested only by an increased potassium level (6.5 to 8 mEq/L) and characteristic electrocardiographic changes (peaking of T waves, loss of P waves, depression of ST segment, prolongation of the QT interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9 to 12 mEq/L). Continuous or serial electrocardiography may be appropriate in some patients during replacement therapy, particularly if given intravenously.

Procyclidine 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 potassium chloride in Slow-K has a major potential interaction with Burns, External.

The use of potassium salts is contraindicated in patients with hyperkalemia, since a further increase in serum potassium concentration in such patients can lead to cardiac arrhythmias or arrest.

Continuous or serial electrocardiography may be appropriate in some patients during replacement therapy, particularly if given intravenously.

Procyclidine 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.

The potassium chloride in Slow-K has a major potential interaction with Dehydration.

Administration of potassium salts in severe dehydration may predispose to renal impairment. Therapy with potassium salts should be administered cautiously in patients with acute dehydration (e.g., due to severe or prolonged diarrhea or heat stress). Close monitoring of serum potassium concentrations is recommended, as potentially fatal hyperkalemia can develop rapidly and is often asymptomatic, manifested only by an increased potassium level (6.5 to 8 mEq/L) and characteristic electrocardiographic changes (peaking of T waves, loss of P waves, depression of ST segment, prolongation of the QT interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9 to 12 mEq/L). Continuous or serial electrocardiography may be appropriate in some patients during replacement therapy, particularly if given intravenously.

The potassium chloride in Slow-K has a major potential interaction with Dehydration.

Potassium chloride liquid suspension contains the stool softener, docusate sodium, as a dispersing agent. Clinical studies with potassium chloride liquid suspension indicate that minor changes in stool consistency may be common though usually well tolerated. However, patients may rarely experience diarrhea or cramping abdominal pain. Patients with severe or chronic diarrhea or who are dehydrated ordinarily should not be prescribed potassium chloride liquid suspension.

The potassium chloride in Slow-K has a major potential interaction with Esophageal Disease.

The use of all solid oral formulations of potassium is contraindicated in patients with arrested or delayed gastrointestinal (GI) transit, whether due to structural, pathological, or pharmacological causes. Potassium is irritating to the GI mucosa and may cause ulcerative and/or stenotic lesions during prolonged physical contact. Based on spontaneous adverse reaction reports, the frequency of small bowel lesions associated with enteric-coated preparations of potassium chloride is 40 to 50 per 100,000 patient-years, while that for wax matrix controlled-release formulations is less than one per 100,000 patient years. Esophageal ulceration has also been reported following administration of controlled-release formulations of potassium chloride in cardiac patients with esophageal compression due to enlarged left atrium. Potassium supplementation should be administered as a liquid preparation or as an aqueous suspension in patients with esophageal obstruction and/or delayed gastrointestinal transit time.

Because of ulcerogenic effects, oral potassium should be administered cautiously in patients with peptic ulcers or other upper gastrointestinal diseases associated with inflammation, bleeding, or perforation. Patients should be advised not to crush, chew, or break potassium tablets or capsules, and to take them with meals and a full glass of water or other liquid. Potassium liquids should be diluted prior to consumption.

Procyclidine 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 potassium chloride in Slow-K has a major potential interaction with Familial Periodic Paralysis.

Administration of potassium salts may precipitate attacks in familial hyperkalemic periodic paralysis or paramyotonia congenita. Therapy with potassium preparations should be administered cautiously in patients with these conditions.

The potassium chloride in Slow-K has a major potential interaction with Hyperkalemia.

The use of potassium salts is contraindicated in patients with hyperkalemia, since a further increase in serum potassium concentration in such patients can lead to cardiac arrhythmias or arrest. Potassium therapy should be administered cautiously in patients with conditions predisposing to hyperkalemia, such as chronic renal failure, systemic acidosis, acute dehydration, hypoaldosteronism (e.g., due to primary adrenal insufficiency or congenital adrenal enzyme deficiency), uncontrolled diabetes mellitus, and extensive tissue breakdown (e.g., due to severe burns, intravascular hemolysis, tumor lysis syndrome, or rhabdomyolysis).

Procyclidine 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.

Procyclidine 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.

Procyclidine has a moderate potential interaction with Liver Disease.

The clearance of anticholinergics may be decreased in the presence of liver disease. Therapy with anticholinergics should be administered cautiously and may require less frequent dosing to avoid adverse effects in patients with liver disease.

The potassium chloride in Slow-K has a major potential interaction with Peptic Ulcer.

The use of all solid oral formulations of potassium is contraindicated in patients with arrested or delayed gastrointestinal (GI) transit, whether due to structural, pathological, or pharmacological causes.

The potassium chloride in Slow-K has a major potential interaction with Renal Dysfunction.

The use of potassium salts is contraindicated in patients with severe renal impairment characterized by oliguria, anuria, or azotemia. Since potassium is excreted by the kidney, the administration of potassium salts in such patients, particularly by the intravenous route, may produce hyperkalemia and cardiac arrhythmias or arrest. Therapy with potassium salts should be administered cautiously in patients with diminished renal function or other conditions which impairs potassium excretion (e.g. adrenal insufficiency). Close monitoring of serum potassium concentrations is recommended, as potentially fatal hyperkalemia can develop rapidly and is often asymptomatic, manifested only by an increased potassium level (6.5 to 8 mEq/L) and characteristic electrocardiographic changes (peaking of T waves, loss of P waves, depression of ST segment, prolongation of the QT interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9 to 12 mEq/L). Continuous or serial electrocardiography may be appropriate in some patients during replacement therapy, particularly if given intravenously.

Procyclidine has a major potential interaction with Tardive Dyskinesia.

Anticholinergic agents and agents with secondary anticholinergic activity may aggravate tardive dyskinesia or induce previously suppressed symptoms. Therapy with these agents should be avoided, if possible, or administered cautiously in patients with preexisting tardive dyskinesia, particularly in the elderly. If tardive dyskinesia symptoms develop or worsen during treatment with an anticholinergic agent, prompt withdrawal of therapy will provide better chances of improving the condition.

Procyclidine 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.
