DESCRIPTION
Oxybutynin chloride is a white crystalline solid, readily soluble in water and acids, but relatively insoluble in alkalis. Chemically, it is the d,i-(racemic) form of 4-diethyl-amino-2-butynyl phenylcyclohexylglycolate hydrochloride with the following formula:
C22H32ClNO3 M.W. 393.9
Each tablet for oral administration contains oxybutynin chloride, USP 5 mg.
Inactive ingredients include calcium stearate, microcrystalline cellulose, anhydrous lactose, sodium starch glycolate and FD&C Blue #1.

CLINICAL PHARMACOLOGY
Oxybutynin chloride exerts direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. It exhibits only one-fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects).
Oxybutynin relaxes bladder smooth muscle. In patients with conditions characterized by involuntary bladder contractions, cystometric studies have demonstrated that oxybutynin increases bladder (vesical) capacity, diminishes the frequency of uninhibited contractions of the detrusor muscle, and delays the initial desire to void. Oxybutynin thus decreases urgency and the frequency of both incontinent episodes and voluntary urination.
Oxybutynin chloride was well tolerated in patients administered the drug in controlled studies of 30 days duration and in uncontrolled studies in which some of the patients received the drug for two years. Pharmacokinetic information is not currently available.
- INDICATIONS AND USAGE
-
CONTRAINDICATIONS
Oxybutynin chloride is contraindicated in patients with untreated angle closure glaucoma and in patients with untreated narrow anterior chamber angles since anticholinergic drugs may aggravate these conditions. It is also contraindicated in partial or complete obstruction of the gastrointestinal tract, paralytic ileus, intestinal atony of the elderly or debilitated patient, megacolon, toxic megacolon complicating ulcerative colitis, severe colitis and myasthenia gravis. It is contraindicated in patients with obstructive uropathy and in patients with unstable cardiovascular status in acute hemorrhage.
Oxybutynin chloride is contraindicated in patients who have demonstrated hypersensitivity to the product.
-
WARNINGS
Oxybutynin chloride, when administered in the presence of high environmental temperature, can cause heat prostration (fever and heat stroke due to decreased sweating). Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance, treatment with oxybutynin chloride would be inappropriate and possibly harmful.
Oxybutynin chloride 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.
Alcohol or other sedative drugs may enhance the drowsiness caused by oxybutynin.
-
PRECAUTIONS
Oxybutynin chloride should be used with caution in the elderly and in all patients with autonomic neuropathy, hepatic or renal disease. Oxybutynin may aggravate the symptoms of hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, hiatal hernia, tachycardia, hypertension, and prostatic hypertrophy.
Administration of oxybutynin chloride to patients with ulcerative colitis may suppress intestinal motility to the point of producing a paralytic ileus and precipitate or aggravate toxic megacolon, a serious complication of the disease.
Carcinogenesis, Mutagenesis, Impairment of Fertility
A 24-month study in rats at dosages up to approximately 400 times the recommended human dosage showed no evidence of carcinogenicity.
Oxybutynin showed no increase in mutagenic activity when tested in Schizosac-charomyces pompholiciformis, Saccharomyces cerevisiae, and Salmonella typhimurium test symptoms. Reproduction studies in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility.
Pregnancy
Category B: Reproduction studies in the hamster, rabbit, rat, and mouse have shown no definite evidence of impaired fertility or harm to the animal fetus. The safety of oxybutynin chloride administered to women who are or who may become pregnant has not been established. Therefore, oxybutynin should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards.
-
ADVERSE REACTIONS
Following administration of oxybutynin chloride, the symptoms that can be associated with the use of other anticholinergic drugs may occur:
Cardiovascular: Palpitations, tachycardia, vasodilatation.
Dermatologic: Decreased sweating, rash.
Gastrointestinal/Genitourinary: Constipation, decreased gastrointestinal motility, dry mouth, nausea, urinary hesitance and retention.
Nervous System: Asthenia, dizziness, drowsiness, hallucinations, insomnia, restlessness.
Ophthalmic: Amblyopia, cycloplegia, decreased lacrimation, mydriasis.
Other: Impotence, suppression of lactation.
-
OVERDOSAGE
The symptoms of overdosage with oxybutynin chloride may be any of those seen with other anticholinergic agents. Symptoms may include signs of central nervous system excitation (e.g., restlessness, tremor, irritability, convulsions, delirium, hallucinations), flushing, fever, nausea, vomiting, tachycardia, hypotension or hypertension, respiratory failure, paralysis, or coma.
In the event of an overdose or exaggerated response, treatment should be symptomatic and supportive. Maintain respiration and induce emesis or perform gastric lavage (emesis is contraindicated in precomatose, convulsive, or psychotic state). Activated charcoal may be administered as well as a cathartic. Physostigmine may be considered to reverse symptoms of anticholinergic intoxication.
Hyperpyrexia may be treated symptomatically with ice bags or other cold applications and alcohol sponges.
