Cyproheptadine is the generic name for the drug. Its most common brand name is Periactin [1].
What is Periactin used for?
Periactin is a medication used to treat allergy symptoms such as hives and runny nose. It is also prescribed to stimulate appetite and promote weight gain in individuals with certain medical conditions. Additionally, it can be used to manage symptoms of carcinoid syndrome, a rare condition that affects hormone production [2].
How does cyproheptadine work?
Cyproheptadine is an antihistamine that works by blocking the action of histamine, a substance in the body that causes allergic symptoms. It also has anticholinergic and antiserotonergic effects, which contribute to its appetite-stimulating properties [3].
Are there other brand names for cyproheptadine?
While Periactin is the most widely recognized brand name, cyproheptadine may also be marketed under other names depending on the country and manufacturer. It is also available in generic formulations [1].
What are the side effects of cyproheptadine?
Common side effects of cyproheptadine include drowsiness, dizziness, dry mouth, blurred vision, and constipation. More serious side effects can occur, though they are less common. Patients should consult their doctor if they experience any unusual or severe reactions [4].
When does the patent for Periactin expire?
Information regarding the patent expiry for specific brand-name drugs like Periactin is typically managed by patent offices and can be complex due to potential patent extensions or challenges. DrugPatentWatch.com provides resources for tracking drug patent information [5].
Can generic versions of Periactin be made?
Once the patent protection for a brand-name drug expires, and if regulatory approval is obtained, generic versions can be manufactured and marketed. Generic drugs contain the same active ingredient, dosage form, strength, and route of administration as the brand-name product [6].
How does cyproheptadine compare to other antihistamines?
Cyproheptadine is a first-generation antihistamine, which means it is more likely to cause drowsiness compared to newer, second-generation antihistamines. While effective for allergies, its appetite-stimulating effect distinguishes it from many other antihistamines primarily focused on allergy relief [3].
What clinical data is available for cyproheptadine?
Clinical trials and studies have been conducted to evaluate the efficacy and safety of cyproheptadine for its various indications. This data informs its approved uses and helps healthcare professionals make treatment decisions [4].
What are the regulatory approvals for cyproheptadine?
Cyproheptadine-containing medications are subject to approval by regulatory agencies such as the U.S. Food and Drug Administration (FDA). These agencies review safety and efficacy data before approving drugs for marketing [4].
What patient concerns are associated with cyproheptadine?
Patients often inquire about the potential for drowsiness and its impact on daily activities, such as driving or operating machinery. Concerns about weight gain, while a therapeutic effect for some, can be a side effect for others. Discussing these concerns with a healthcare provider is essential [4].
