Quibron-T

Product Monograph: Quibron-T (Theophylline, Extended-Release) Therapeutic Classification: Bronchodilator / Methylxanthine Schedule: Prescription Only (S4) 1. What is Quibron-T? A Deep Dive into Sustained Bronchodilation Look, I’ve been in practice for over twenty years, and I’ve seen respiratory pharmacology shift dramatically—from theophylline being the first-line workhorse to the rise of inhaled corticosteroids and long-acting beta agonists. But Quibron-T? This old warhorse still has a place in the stable, especially for that specific subset of patients who don’t tolerate inhaled therapies well or need that continuous, low-level bronchodilation overnight.
