A 25 year old asthmatic patient on theophylline is given ciprofloxacin by his dentist. He developed dyspnea and palpitations. Probable cause is:
Ciproﬂoxacin reduces plasma protein binding of theophylline
Ciproﬂoxacin inhibits metabolism of theophylline
Ciproﬂoxacin increases metabolism of theophylline
Ciproﬂoxacin displaces receptor binding of theophylline
