Global InformationTedral information
Tedral is a medicine formerly used to treat respiratory diseases such as asthma, chronic obstructive lung disease (COPD), chronic bronchitis, and emphysema.[1] It is a combination drug containing three active ingredients - theophylline, ephedrine, phenobarbital.[1] This medication relaxes the smooth muscle of the airways, making breathing easier.[2] The common side effects of Tedral include gastrointestinal disturbances, dizziness, headache and lightheadedness.[2][3][4] However, at high dose, it may lead to cardiac arrhythmias, hypertension, seizures or other serious cardiovascular and/or central nervous system adverse effects.[5][6][7] Tedral is contraindicated in individuals with hypersensitivity to theophylline, ephedrine and/or phenobarbital. It should be also used in caution in patients with cardiovascular complications, such as ischemic heart disease and heart failure and/or other disease conditions.[2][8] It can cause a lot of drug–drug interactions. Therefore, before prescribing patient with Tedral, drug interactions profile should be carefully checked if the patient had other concurrent medication(s). Being used as a treatment option for respiratory diseases for decades, Tedral was withdrawn from the US market in 2006 due to safety concerns.[9][10]
