概要
Both theophylline and bupropion lower the seizure threshold, so combined use increases the risk of seizures. This is particularly relevant when theophylline levels are elevated or bupropion doses are high.
この相互作用をわかりやすく説明すると
Bupropion and Theophylline can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Bupropion belongs to Central Nervous System; Theophylline belongs to Respiratory.
なぜ起こるのか
Additive pharmacodynamic lowering of the seizure threshold.
対処法
Avoid the combination when possible, or use the lowest effective bupropion dose with gradual titration. Keep theophylline levels within the therapeutic range and avoid in patients with other seizure risk factors.
