Does atropine worsen bradycardia...

Does atropine worsen bradycardia?

Atropine doses below 0.5 mg should be avoided, because sub-therapeutic atropine levels can cause bradycardia. At higher doses, the dominant effect of atropine is usually to increase the heart rate. Doses <0.5 milligram and slow injection have been associated with paradoxical bradycardia.

Can atropine cause liver damage?

Hepatotoxicity. Despite widespread use over many decades, atropine has not been linked convincingly to episodes of liver enzyme elevations or clinically apparent liver injury. Atropine is metabolized by the liver, but is usually given in low doses (<1 mg) for short periods only.

Does atropine cause gastrointestinal spasms?

Normally when acetylcholine acts on these receptors it causes the muscle in the gut to contract. By preventing this, atropine helps the muscle in the gut to relax. This reduces involuntary contractions and spasms of the muscle.近視加深

Will atropine decrease HR?

High doses of atropine cause blockade of muscarinic receptors at the cardiac sinoatrial node and are parasympatholytic, markedly increasing heart rate and decreasing heart rate variability.

What is atropine used to control?

Atropine Sulfate Injection is an antimuscarinic agent used to treat bradycardia (low heart rate), reduce salivation and bronchial secretions before surgery, as an antidote for overdose of cholinergic drugs or mushroom poisoning.
