beta blocker

Beta-adrenergic blocking agent.

bronchial blocker

Abbreviation: BB
A device for facilitating single-lung ventilation during thoracic surgery or thoracoscopy. The bronchial blocker is placed into the mainstem bronchus on the side of the chest where the operation is being performed, and its balloon is inflated within the airway. Potential complications of the device include dislodgement, misplacement, or accumulation of fluid behind the blockade.

calcium channel blocker

Abbreviation: CCB
Any of a group of drugs that slow the influx of calcium ions into smooth muscle cells, resulting in decreased arterial resistance and oxygen demand. These drugs are used to treat angina, hypertension, vascular spasm, intracranial bleeding, congestive heart failure, and supraventricular tachycardia. Because hypotension occurs as both an intended and, occasionally, an unwelcome effect, blood pressure must be monitored especially closely during the initial treatment period.

H2 blocker

See: H2-receptor antagonist

Interestingly, additional pharmacogenetic testing did not explain the occurrence of this side effect, since the patient was found to be extensive metabolizer of beta blocking agents.
Landmark study results reported by researchers showed that the beta blocking agent Coreg(r) (carvedilol) decreased mortality rates by 35 percent in patients with the most advanced stage of heart failure who were already taking standard therapy.
While the introduction of treatment with beta blocking agents, angiotensin converting enzyme (ACE) inhibitors, and aldosterone antagonists has significantly reduced mortality in CHF, the condition remains the leading cause of hospital admissions in patients over 65 years of age.
