Mirakof® SR 50 mg is a sustained-release tablet containing Butamirate Citrate, a non-opioid antitussive agent. It is used to relieve dry (non-productive) coughs associated with various conditions, including viral infections, acute lower respiratory tract infections (such as tracheitis, laryngitis, and bronchitis), whooping cough, and for pre- and post-operative cough sedation in patients undergoing surgical procedures and bronchoscopy. The medication acts directly on the brain's cough center to suppress the cough reflex without causing sedation. It is rapidly absorbed, reaching maximum concentration within 9 hours, and has a plasma elimination half-life of approximately 13 hours.
