Final answer:
Benzonatate (Tessalon Perles) is used for cough suppression, not for pain relief, insomnia, or digestive disorders. It works by numbing the airways and lungs' sensory receptors to reduce the cough reflex.
Step-by-step explanation:
Benzonatate (Tessalon Perles) is primarily indicated for cough suppression. It belongs to a class of medications known as antitussives, which are substances which suppress the coughing itself rather than increasing mucus production. Unlike analgesic medications, which are intended for pain relief without loss of consciousness, or narcotic analgesics that may cause drowsiness and loss of consciousness at higher doses, benzonatate is specifically designed to reduce cough reflex by numbing the airways and lungs' sensory receptors. It is not used for pain relief, insomnia, digestive disorders, or as an anti-anxiety medication, which are different classes of drugs with distinct indications.
