Bevonium is a prescription drug used to treat high blood pressure. It belongs to a class of drugs called angiotensin receptor blockers (ARBs). ARBs work by blocking the action of a hormone called angiotensin II, which causes blood vessels to constrict and can lead to high blood pressure. Bevonium helps relax blood vessels and lower blood pressure, reducing the risk of stroke, kidney disease, and other serious health conditions. Bevonium is taken once daily and should be taken with food. Common side effects of Bevonium include dizziness, headache, and nausea.
Bevonium, also known by its chemical name piribenzil, was a parasympatholytic antimuscarinic drug with several properties:
- Antimuscarinic: Bevonium blocked the action of the neurotransmitter acetylcholine in the body, specifically at muscarinic receptors. This led to the relaxation of smooth muscles in various organs.
- Antispasmodic: Bevonium helped relax smooth muscles in the digestive and urinary tracts, relieving spasms and pain.
- Bronchodilator: In the airways, Bevonium relaxed smooth muscles, potentially easing breathing in conditions like asthma.
However, it's crucial to note that Bevonium is no longer a commercially available medication. Its use was discontinued due to the availability of safer and more effective alternatives with similar properties.
Here are some additional points about Bevonium:
- Common form: Bevonium was often used as its methyl sulfate salt (Bevonium metilsulfate).
- Mechanism of action: By blocking acetylcholine at muscarinic receptors, Bevonium interfered with the normal function of the parasympathetic nervous system, which is responsible for various involuntary bodily functions.
- Side effects: Bevonium could cause various side effects, including dry mouth, constipation, blurred vision, urinary retention, and dizziness.
