How Does Optivar Work?
Optivar is part of a class of drugs called antihistamines. Specifically, it is an H1 receptor antagonist. This means that it blocks a specific type of histamine receptor in the body (known as H1 receptors). Because allergic reactions are partly caused by the release of histamine from certain cells in the body, Optivar can help relieve or prevent allergy symptoms
In addition to blocking histamine receptors, Optivar also seems to decrease the release of histamine from the cells in the body and may also inhibit other substances (such as leukotrienes), which are produced by the body in response to an allergen.
In clinical studies, Optivar was shown to prevent and relieve itching of the eyes due to allergies. In these studies, a dose of this medication was shown to start working quickly (within three minutes) and last for about eight hours.
