Oxyphenonium Bromide
Before using Oxyphenonium Bromide, it is crucial for patients to consult their healthcare provider due to several important precautions:
- Caution in Pre-existing Conditions: Oxyphenonium Bromide has anticholinergic properties and should be used cautiously in patients with glaucoma, urinary retention, myasthenia gravis, intestinal obstruction, and severe heart disease. These conditions can be worsened by the drug’s action on the autonomic nervous system.
- Elderly Patients: Older adults are more susceptible to the sedative and cognitive effects of Oxyphenonium Bromide, which may cause confusion, drowsiness, or blurred vision, potentially impairing the ability to perform daily activities. Doses should be started low and adjusted accordingly.
- Central Nervous System (CNS) Effects: The drug can cause drowsiness, confusion, and dizziness, which can be particularly concerning for patients engaging in activities that require full mental alertness, such as driving or operating heavy machinery.
- Renal and Hepatic Impairment: In patients with liver or kidney dysfunction, dose adjustments may be necessary due to altered drug metabolism and excretion. Monitoring may be required in these populations.
- Pregnancy and Breastfeeding: Oxyphenonium Bromide falls under Category C for pregnancy, meaning it may pose risks to a developing fetus, and should only be used if the potential benefits outweigh the risks. The drug may also pass into breast milk and should be avoided while breastfeeding unless advised by a healthcare provider.
- Monitor for Adverse Reactions: It is important to be vigilant for any severe side effects such as tachycardia, hypertension, or severe constipation, especially in older adults or patients with cardiovascular issues.
Oxyphenonium Bromide is primarily used for its anticholinergic and antispasmodic effects. It is indicated for:
- Irritable Bowel Syndrome (IBS): It is commonly prescribed for IBS to alleviate symptoms such as abdominal cramps, gas, and intestinal spasms.
- Peptic Ulcers: Oxyphenonium can help reduce gastrointestinal motility and gastric acid secretion, aiding in the management of peptic ulcers by preventing further irritation and promoting healing.
- Gastrointestinal Disorders: It is used to reduce intestinal cramping and discomfort associated with various gastrointestinal disorders, including gastroenteritis and post-operative ileus (intestinal paralysis following surgery).
- Other Spastic Conditions: It may be prescribed for various conditions associated with smooth muscle spasms, such as bladder spasm and certain respiratory conditions.
Oxyphenonium Bromide should not be used in the following conditions:
- Glaucoma: Particularly contraindicated in patients with angle-closure glaucoma or other forms of glaucoma due to the risk of increasing intraocular pressure.
- Urinary Retention: It is contraindicated in patients with urinary retention or obstructive uropathy, as it can further inhibit the ability to urinate.
- Severe Heart Disease: Oxyphenonium Bromide can worsen cardiac arrhythmias and should not be used in patients with severe cardiovascular conditions such as heart failure, arrhythmias, or myocardial infarction.
- Myasthenia Gravis: As it may exacerbate muscle weakness, it should not be used in individuals with myasthenia gravis.
- Hypersensitivity: Patients with known hypersensitivity to Oxyphenonium Bromide or any of its components should avoid using the drug.
Common and severe side effects of Oxyphenonium Bromide include:
- Common Side Effects:
- Dry Mouth: A typical anticholinergic side effect that may lead to difficulty swallowing and discomfort.
- Constipation: Due to the drug’s effect on the gastrointestinal system, constipation is a common side effect and may require dietary changes or additional interventions.
- Blurred Vision: As a result of its anticholinergic properties, Oxyphenonium Bromide can impair accommodation, leading to blurred vision.
- Drowsiness: Sedation is a common side effect, leading to impaired mental alertness and difficulty concentrating.
- Severe Side Effects:
- Tachycardia: An increase in heart rate may indicate the development of cardiac arrhythmias, a serious side effect requiring immediate medical attention.
- Urinary Retention: Difficulty urinating or complete urinary retention may occur, especially in patients with pre-existing urinary conditions.
- Severe Dizziness or Confusion: Particularly in elderly patients, severe dizziness or cognitive impairment may occur, which can affect day-to-day functioning.
- Severe Allergic Reactions: Rare, but severe allergic reactions such as rash, itching, swelling, and difficulty breathing may indicate an anaphylactic response.

Oxyphenonium Bromide is a muscarinic antagonist and anticholinergic agent. It works by blocking the action of acetylcholine at muscarinic receptors in smooth muscles, leading to:
- Reduction in Smooth Muscle Contraction: It reduces the tone of smooth muscles, particularly in the gastrointestinal and urinary systems, helping to alleviate spasms and cramping.
- Decreased Gastric Acid Secretion: Oxyphenonium inhibits the secretion of gastric acid, which is beneficial in treating conditions like peptic ulcers and gastroesophageal reflux disease (GERD).
- Improved Gastrointestinal Motility: By relaxing the smooth muscles, it slows down gut motility, providing relief in conditions where excessive motility (like diarrhea) or spasm is problematic.
Oxyphenonium Bromide can interact with a variety of substances, which may affect its effectiveness or safety:
- CNS Depressants: Combining Oxyphenonium Bromide with other CNS depressants (such as benzodiazepines, antihistamines, or alcohol) can enhance drowsiness and sedation, increasing the risk of dizziness and fall-related injuries.
- Other Anticholinergics: Co-administration with other anticholinergic medications (e.g., atropine, scopolamine, antihistamines) can intensify the dry mouth, constipation, and urinary retention effects.
- Antacids: Antacids may affect the absorption of Oxyphenonium Bromide, potentially reducing its therapeutic effect. It is advised to space the intake of antacids and Oxyphenonium by at least an hour.
- Antidiarrheal Medications: Combining Oxyphenonium Bromide with antidiarrheal agents (e.g., loperamide) may cause excessive slowing of gut motility, leading to severe constipation or bowel obstruction.
For Oxyphenonium Bromide, the typical starting dose is:
- Oral Dose: The usual adult dose is 1 to 2 mg taken orally two to three times daily.
- Adjustments: The dose may be increased based on the patient's response, with a maximum dose typically around 6 mg/day.
- Duration: Treatment should be continued as prescribed by the healthcare provider. Doses may be reduced or discontinued if adverse effects occur.
Oxyphenonium Bromide is typically not recommended for use in pediatric patients, particularly those under the age of 18, as its safety and efficacy have not been well established in this population. For children, alternative treatments should be explored based on their specific condition.

In patients with renal impairment, Oxyphenonium Bromide should be used cautiously. Dose adjustments may be necessary due to decreased renal clearance, leading to drug accumulation and increased risk of adverse effects. Patients with severe kidney dysfunction may require closer monitoring and possible dose reduction.
