Benzydamine oral rinse is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to treat and prevent mouth pain, inflammation, and swelling. The active ingredient, benzydamine, is an analgesic and anti-inflammatory agent that works by blocking the production of prostaglandins, which are chemicals in the body that cause pain and inflammation. Benzydamine oral rinse is available by prescription only and is typically used to treat conditions such as mouth sores, gum inflammation, and pain after dental procedures.
Pharmacology and Mechanism of Action
Benzydamine is a pyridine derivative with anti-inflammatory, analgesic, and antipyretic properties. It is believed to work by inhibiting the synthesis of prostaglandins, which are key mediators of inflammation and pain. By reducing prostaglandin production, benzydamine helps to alleviate pain, swelling, and inflammation in the mouth and throat. The exact mechanism of action of benzydamine is not fully understood, but it is thought to involve the inhibition of cyclooxygenase (COX) enzymes, which are responsible for converting arachidonic acid into prostaglandins.
Indications and Usage
Benzydamine oral rinse is indicated for the treatment and prevention of mouth pain, inflammation, and swelling. It is commonly used to treat conditions such as:
- Mouth sores and ulcers
- Gum inflammation and gingivitis
- Pain after dental procedures, such as tooth extraction or surgery
- Mucositis, a condition characterized by inflammation and ulceration of the mucous membranes in the mouth and throat
Benzydamine oral rinse is typically used as a 0.15% solution, which is swished around the mouth for 30 seconds to 1 minute before being spit out. The usual dosage is 15 mL, used 3-4 times a day, as needed.
| Indication | Dosage | Frequency |
|---|---|---|
| Mouth sores and ulcers | 15 mL | 3-4 times a day |
| Gum inflammation and gingivitis | 15 mL | 3-4 times a day |
| Pain after dental procedures | 15 mL | 3-4 times a day, as needed |
Contraindications and Precautions
Benzydamine oral rinse is contraindicated in patients with a known hypersensitivity to benzydamine or any other ingredient in the formulation. It is also contraindicated in patients with a history of asthma, as benzydamine may exacerbate asthma symptoms. Precautions should be taken when using benzydamine oral rinse in patients with a history of gastrointestinal bleeding, as NSAIDs can increase the risk of bleeding.
