Can I give otilonium (antimuscarinic agent) to anyone with muscle spasms?

From the Guidelines

No, otilonium should not be given to anyone with muscle spasms without a proper diagnosis and consideration of its specific indications. Otilonium is specifically indicated for treating abdominal pain and discomfort associated with irritable bowel syndrome (IBS) and other functional gastrointestinal disorders, as stated in the british society of gastroenterology guidelines on the management of irritable bowel syndrome 1. It works by blocking muscarinic receptors and calcium channels in the smooth muscle of the gastrointestinal tract, helping to reduce intestinal spasms and pain. Some key points to consider when prescribing otilonium include:

• The typical dosage for adults with IBS is 40-80 mg taken 2-3 times daily before meals.
• Otilonium should be avoided in patients with glaucoma, urinary retention, prostatic hypertrophy, or known hypersensitivity to the drug.
• Common side effects include dry mouth, constipation, and blurred vision. For skeletal muscle spasms, more appropriate treatments would include muscle relaxants like baclofen, cyclobenzaprine, or tizanidine, depending on the cause and location of the spasms, as antispasmodics are among the most frequently used over-the-counter treatments for IBS and can be divided into antimuscarinics and smooth muscle relaxants 1. Always consult with a healthcare provider for proper diagnosis and treatment of muscle spasms.

From the FDA Drug Label

The FDA drug label specifically mentions relief of minor aches and pains of muscles and joints due to certain conditions, but it does not directly mention muscle spasms as an indication for use 2.

From the Research

Administration of Otilonium for Muscle Spasms

• Otilonium bromide is a spasmolytic agent that has been primarily used to treat patients with Irritable Bowel Syndrome (IBS) [(3,4,5,6)].
• The drug acts locally in the large bowel wall, inhibiting the main patterns of human colonic motility and contractility caused by excitatory motor neurons stimulation and excitatory neurotransmitters [(3,5)].
• Otilonium bromide has been shown to be effective in reducing gastrointestinal symptoms and abdominal pain in patients with IBS [(4,5,6)].
• However, its use is not limited to IBS, as it has also been used as a premedication for gastrointestinal endoscopic procedures due to its spasmolytic effect 7.

Considerations for Administration

• Otilonium bromide is a calcium antagonist with a direct myolytic effect, which makes it suitable for use in spastic conditions and functional dyskinesias of the gastroenteric apparatus 7.
• The drug has been shown to be well-tolerated, with no significant side effects reported in clinical studies [(4,7,6)].
• While otilonium bromide may be effective in treating muscle spasms, its use should be limited to patients with specific conditions, such as IBS or those undergoing gastrointestinal endoscopic procedures [(3,4,7,5,6)].

Specific Conditions for Use

• Otilonium bromide is not recommended for use in patients with muscle spasms due to other causes, as its efficacy and safety in these conditions have not been established [no direct evidence].
• Patients with certain medical conditions, such as gastrointestinal obstruction, or those taking certain medications, should use otilonium bromide with caution and under medical supervision [no direct evidence].
