Tedral

Tedral is a pharmaceutical drug that was commonly used to treat asthma and bronchitis. It was manufactured by the Abbott Laboratories and was discontinued in the United States in 1999. The active ingredients in Tedral were theophylline, ephedrine, and phenobarbital.

Composition[edit | edit source]

Tedral contained three active ingredients: theophylline, ephedrine, and phenobarbital.

Theophylline is a bronchodilator that works by relaxing the muscles around the airways in the lungs, which allows them to open up and makes it easier to breathe.
Ephedrine is a decongestant and bronchodilator that reduces swelling and constricts blood vessels in the nasal passages and widens the lung airways, allowing you to breathe more easily.
Phenobarbital is a barbiturate, used to relieve anxiety and induce sleep, but in this context, it was used to counteract the stimulant effects of theophylline and ephedrine.

Uses[edit | edit source]

Tedral was primarily used to treat asthma and bronchitis. It helped to control symptoms such as wheezing, shortness of breath, and chest tightness.

Discontinuation[edit | edit source]

Tedral was discontinued in the United States in 1999 by its manufacturer, Abbott Laboratories. The reasons for the discontinuation were not publicly disclosed, but it is speculated that the development of newer, safer asthma medications may have played a role.

Side Effects[edit | edit source]

Like all medications, Tedral had potential side effects. These included insomnia, nervousness, nausea, and palpitations. Due to the presence of phenobarbital, prolonged use could potentially lead to drug dependence.
