Current asthma medicines include inhalers. A common inhaler used in asthma is called a beta-agonist (for example salbutamol). They improve asthma symptoms by stimulating areas in the human airway resulting in widening of the human airway. Although these drugs are useful after the first dose, longterm use can cause worsening asthma symptoms.
Beta-blockers are the complete opposite type of medication. Just now they are avoided in patients with asthma as after the first dose they can cause airway narrowing and cause an asthma attack.
New research has suggested that long term use of beta-blockers can reduce airway inflammation which can improve asthma control and improve symptoms.
This research was done in asthmatic patients who didn't need inhaled steroids to control their asthma. What the investigators want to do is see if the same benefit of beta-blocker use is asthma can be seen in people who take inhaled steroids.

There is an unsatisfied medical need for a first-line treatment of proliferating IHs with a good benefit/risk profile. Based on the recent findings of encouraging results obtained with pro...
The purpose of this study is to determine whether propranolol can decrease pain symptoms in a common subset of patients admitted to a burn center after thermal burn.
Propranolol has been the first-line treatment for alarming hemangiomas. However, some hemangiomas are propranolol-resistant. The authors reported 1 propranolol-resistant hemangioma which was treated w...

A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.
Asthma attacks caused, triggered, or exacerbated by OCCUPATIONAL EXPOSURE.
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
A cardioselective beta-adrenergic blocker possessing properties and potency similar to PROPRANOLOL, but without a negative inotropic effect.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
