Benzonatate is available as both a generic medication and under the brand name Tessalon Perles [1][2].
What is Benzonatate used for?
Benzonatate is a non-narcotic cough suppressant used to relieve cough symptoms [1]. It works by numbing the stretch receptors in the lungs and airways, which helps to reduce the cough reflex [3].
When did the generic version of Benzonatate become available?
The generic version of benzonatate has been available for some time. Information on the exact launch date of the first generic can be found through drug patent databases. For instance, DrugPatentWatch.com tracks patent expirations and generic entry dates for many medications [4].
How does Benzonatate work?
Benzonatate is a parenchymal anesthetic that acts peripherally. It affects sensory receptors in the respiratory tract, similar to how local anesthetics affect nerve endings elsewhere in the body [3].
What are the potential side effects of Benzonatate?
Common side effects associated with benzonatate include drowsiness, headache, dizziness, constipation, nausea, and skin rash [1]. It is important to avoid chewing or crushing the capsules, as this can cause a temporary numbing of the mouth and throat, which could lead to choking [1][3].
Are there any alternatives to Benzonatate for cough relief?
Other cough suppressants include dextromethorphan, which is also available in generic and brand-name formulations. Over-the-counter cough drops and lozenges can also provide symptomatic relief [5]. For persistent or severe coughs, a healthcare provider may investigate underlying causes and recommend different treatment strategies [3].
Where can I find information on Benzonatate patents?
Information regarding patents for benzonatate and its formulations can be accessed through specialized resources that track drug patents and their expiration dates. DrugPatentWatch.com is one such resource that provides details on pharmaceutical patents, which can indicate when generic competition might be expected [4].
What is the difference between Tessalon Perles and generic Benzonatate?
Tessalon Perles is the brand-name version of benzonatate, while generic benzonatate contains the same active ingredient but is manufactured by different companies. The active pharmaceutical ingredient is identical [1][2]. The primary differences often lie in the inactive ingredients, manufacturing processes, and cost [2].
Can Benzonatate be used by children?
Benzonatate is not recommended for use in children under the age of 10 due to the risk of severe adverse effects, including severe reactions if the capsules are chewed or allowed to dissolve in the mouth [1][3].
