Boniton
Boniton - General Information
A nucleoside that is composed of adenine and d-ribose. Boniton or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Boniton itself is a neurotransmitter.
Pharmacology of Boniton
Boniton is an endogenous nucleoside occurring in all cells of the body and is not chemically related to other antiarrhythmic drugs. Boniton is indicated for the conversion to sinus rhythm of paroxysmal supraventricular tachycardia (PSVT), including that associated with accessory bypass tracts (Wolff-Parkinson-White Syndrome). Boniton is antagonized competitively by methylxanthines such as caffeine and theophylline, and potentiated by blockers of nucleoside transport such as dipyridamole. Boniton is not blocked by atropine.
Boniton for patients
Boniton Interactions
Intravenous Adenocard (adenosine) has been effectively administered in the presence of other cardioactive drugs, such as quinidine, beta-adrenergic blocking agents, calcium channel blocking agents, and angiotensin converting enzyme inhibitors, without any change in the adverse reaction profile. Digoxin and verapamil use may be rarely associated with ventricular fibrillation when combined with Adenocard. Because of the potential for additive or synergistic depressant effects on the SA and AV nodes, however, Adenocard should be used with caution in the presence of these agents. The use of Adenocard in patients receiving digitalis may be rarely associated with ventricular fibrillation.
The effects of adenosine are antagonized by methylxanthines such as caffeine and theophylline. In the presence of these methylxanthines, larger doses of adenosine may be required or adenosine may not be effective. Adenosine effects are potentiated by dipyridamole. Thus, smaller doses of adenosine may be effective in the presence of dipyridamole. Carbamazepine has been reported to increase the degree of heart block produced by other agents. As the primary effect of adenosine is to decrease conduction through the A-V node, higher degrees of heart block may be produced in the presence of carbamazepine.
Boniton Contraindications
Intravenous Adenocard (adenosine) is contraindicated in:
1. Second- or third-degree A-V block (except in patients with a functioning artificial pacemaker).
2. Sinus node disease, such as sick sinus syndrome or symptomatic bradycardia (except in patients with a functioning artificial pacemaker).
3. Known hypersensitivity to adenosine.
Additional information about Boniton
Boniton Indication: For controlling paroxysmal supraventricular tachycardia (PSVT). This drug can also be used diagnostically for stable, wide complex tachyardias of unknown type.
Mechanism Of Action: Boniton slows conduction time through the A-V node, can interrupt the reentry pathways through the A-V node, and can restore normal sinus rhythm in patients with paroxysmal supraventricular tachycardia (PSVT), including PSVT associated with Wolff-Parkinson-White Syndrome.
