Each tablet for oral administration contains:
Propantheline bromide USP.................................................. 15 mg
Propantheline bromide, a synthetic quaternary ammonium compound, occurs as white or nearly white crystals. It is odorless and has a bitter taste, and is very soluble in water and chloroform; practically insoluble in ether, acetone and ethyl acetate. It is designated chemically as (2-Hydroxyethyl) diisopropylmethyl-ammonium bromide xanthene-9-carboxylate.
The structural formula is:
Each tablet contains corn starch, hydrogenated vegetable oil, lactose monohydrate and magnesium stearate. In addition to the ingredients listed above, each tablet contains Opacode Black (monogramming ink), Opadry Clear and Opadry White. Opacode Black contains ammonium hydroxide, black iron oxide, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze. Opadry Clear contains hypromellose and polyethylene glycol. Opadry White contains hypromellose, polyetheylene glycol, polysorbate 80 and titanium dioxide.
Propantheline - Clinical Pharmacology
Propantheline bromide inhibits gastrointestinal motility and diminishes gastric acid secretion. The drug also inhibits the action of acetylcholine at the postganglionic nerve endings of the parasympathetic nervous system.
Propantheline bromide is extensively metabolized in man primarily by hydrolysis to the inactive materials xanthene-9-carboxylic acid and (2-hydroxyethyl) diisopropylmethylammonium bromide. In a bioavailability study, peak plasma concentrations of Propantheline were achieved in about one hour, following a single oral dose.
The plasma elimination half-life of Propantheline is about 1.6 hours. Approximately 70% of the dose is excreted in the urine, mostly as metabolites. The urinary excretion of Propantheline is about 3% after oral tablet administration.
Propantheline should be used with caution in the elderly and in all patients with autonomic neuropathy, hepatic or renal disease, hyperthyroidism, coronary heart disease, congestive heart failure, cardiac tachyarrhythmias, hypertension, or hiatal hernia associated with reflux esophagitis, since anticholinergics may aggravate this condition.
In patients with ulcerative colitis, large doses of Propantheline may suppress intestinal motility to the point of producing paralytic ileus and, for this reason, may precipitate or aggravate toxic megacolon, a serious complication of the disease.
Information for Patients
Propantheline may produce drowsiness or blurred vision. The patient should be cautioned regarding activities requiring mental alertness, such as operating a motor vehicle or other machinery or performing hazardous work, while taking this drug.
Anticholinergics may delay absorption of other medication given concomitantly. Excessive cholinergic blockade may occur if Propantheline is given concomitantly with belladonna alkaloids or synthetic and semisynthetic anticholinergic agents, narcotic analgesics such as meperidine, Type 1 antiarrhythmic drugs (e.g., disopyramide, procainamide, or quinidine), antihistamines, phenothiazines, tricyclic antidepressants, or other psychoactive drugs. Propantheline may also potentiate the sedative effect of phenothiazines. Increased intraocular pressure may result from concurrent administration of anticholinergics and corticosteroids.
Concurrent use of Propantheline with slow-dissolving tablets of digoxin may cause increased serum digoxin levels. This interaction can be avoided by using only those digoxin tablets that rapidly dissolve by USP standards.
Carcinogenesis, Mutagenesis, Impairment of Fertility
No long-term fertility, carcinogenicity, or mutagenicity studies have been done with Propantheline.
PregnancyPregnancy Category C
Animal reproduction studies have not been conducted with Propantheline. It is also not known whether Propantheline can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Propantheline should be given to a pregnant woman only if clearly needed.
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Propantheline is administered to a nursing woman. Suppression of lactation may occur with anticholinergic drugs.
Safety and effectiveness in children have not been established.
