Theobid is another brand name for a sustained-release form of theophylline, a bronchodilator used for respiratory conditions. Similar to Slo-bid, Theobid provides a steady release of theophylline over an extended period. This helps manage symptoms of asthma and COPD by keeping airways relaxed and open. It reduces the need for frequent dosing. Think of it as a slow-release version of theophylline.
