VT Doses Atropine 1% (Atropine)

VT Doses Atropine 1% (Atropine) Uses, Dosage, Side Effects, Food Interaction and all others data.

VT Doses Atropine 1% (Atropine) binds to and inhibit muscarinic acetylcholine receptors, producing a wide range of anticholinergic effects. VT Doses Atropine 1% (Atropine) is an anticholinergic agent which competitively blocks the muscarinic receptors in peripheral tissues such as the heart, intestines, bronchial muscles, iris and secretory glands. Some central stimulation may occur. VT Doses Atropine 1% (Atropine) abolishes bradycardia and reduces heart block due to vagal activity. Smooth muscles in the bronchi and gut are relaxed while glandular secretions are reduced. It also has mydriatic and cycloplegic effect.

VT Doses Atropine 1% (Atropine), a naturally occurring belladonna alkaloid, is a racemic mixture of equal parts of d- and l-hyoscyamine, whose activity is due almost entirely to the levo isomer of the drug. VT Doses Atropine 1% (Atropine) is commonly classified as an anticholinergic or antiparasympathetic (parasympatholytic) drug. More precisely, however, it is termed an antimuscarinic agent since it antagonizes the muscarine-like actions of acetylcholine and other choline esters. Adequate doses of atropine abolish various types of reflex vagal cardiac slowing or asystole. The drug also prevents or abolishes bradycardia or asystole produced by injection of choline esters, anticholinesterase agents or other parasympathomimetic drugs, and cardiac arrest produced by stimulation of the vagus. VT Doses Atropine 1% (Atropine) may also lessen the degree of partial heart block when vagal activity is an etiologic factor. VT Doses Atropine 1% (Atropine) in clinical doses counteracts the peripheral dilatation and abrupt decrease in blood pressure produced by choline esters. However, when given by itself, atropine does not exert a striking or uniform effect on blood vessels or blood pressure.

How VT Doses Atropine 1% (Atropine) works

VT Doses Atropine 1% (Atropine) binds to and inhibit muscarinic acetylcholine receptors, producing a wide range of anticholinergic effects.

Dosage

VT Doses Atropine 1% (Atropine) dosage

Adult:

IV: Bradycardia: 500 mcg every 3-5 mins. Total: 3 mg.
IV/IM: Organophosphorus poisoning: 2 mg every 10-30 mins until muscarinic effects disappear or atropine toxicity appears.
IM/SC: Premedication in anesthesia: 300-600 mcg 30-60 mins before anesthesia.
IV/IM/SC: Poisoning or overdosage with compound having muscarinic actions: 0.6-1 mg, repeat 2 hrly.
Ophthalmic: Inflammatory eye disorders: As 0.5-1% solution: 1-2 drops 4 times/day.
Ophthalmic: refraction: 1% solution 1 drop twice daily for 1-2 days before procedure.
Oral: Non ulcer dyspepsia, Irritable bowel syndrome, Diverticular disease: 0.6-1.2 mg as a single dose at bedtime.

Usual Pediatric Dose for Anesthesia:

7 to 16 pounds: 0.1 mg, IV, IM, or subcutaneously
17 to 24 pounds: 0.15 mg, IV, IM, or subcutaneously
24 to 40 pounds: 0.2 mg, IV, IM, or subcutaneously
40 to 65 pounds: 0.3 mg, IV, IM, or subcutaneously
65 to 90 pounds: 0.4 mg, IV, IM, or subcutaneously
Over 90 pounds: 0.4 to 0.6 mg, IV, IM, or subcutaneously

Side Effects

Injection: Dry mouth, dysphagia, constipation, flushing and dryness of skin, tachycardia, palpitations, arrhythmias, mydriasis, photophobia, cycloplegia, raised intraocular pressure. Toxic doses cause tachycardia, hyperpyrexia, restlessness, confusion, excitement, hallucinations, delirium and may progress to circulatory failure and resp depression.

Eye drops or ointment: Systemic toxicity esp in children, on prolonged use may lead to irritation, hyperaemia, oedema and conjunctivitis. Increased intraocular pressure.

Toxicity

Oral, mouse: LD₅₀ = 75 mg/kg. Symptoms of overdose includes widespread paralysis of parasympathetically innervated organs. Dry mucous membranes, widely dilated and nonresponsive pupils, tachycardia, fever and cutaneous flush are especially prominent, as are mental and neurological symptoms. In instances of severe intoxication, respiratory depression, coma, circulatory collapse and death may occur.

Precaution

Reflux oesophagitis; elderly; infants and children; Pregnancy.

Interaction

Additive anticholinergic effects with quinidine, antidepressants and some antihistamines.

Food Interaction

Avoid alcohol.
Take with food.

VT Doses Atropine 1% (Atropine) Alcohol interaction

[Moderate] GENERALLY AVOID:

Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous.

In addition, the potential for abuse may be increased with the combination.

The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system.

No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load.

However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.

Alcohol should generally be avoided during therapy with anticholinergic agents.

Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.

VT Doses Atropine 1% (Atropine) Hypertension interaction

[Minor] Cardiovascular effects of anticholinergics may exacerbate hypertension.

Therapy with anticholinergic agents should be administered cautiously in patients with hypertension.

Elimination Route

VT Doses Atropine 1% (Atropine) is rapidly and well absorbed after intramuscular administration. VT Doses Atropine 1% (Atropine) disappears rapidly from the blood and is distributed throughout the various body tissues and fluids.

Half Life

3.0 ± 0.9 hours in adults. The half-life of atropine is slightly shorter (approximately 20 minutes) in females than males.

Elimination Route

Much of the drug is destroyed by enzymatic hydrolysis, particularly in the liver; from 13 to 50% is excreted unchanged in the urine.

Pregnancy & Breastfeeding use

Pregnancy Category C. Animal reproduction studies have not been conducted with atropine. It also is not known whether atropine can cause fetal harm when given to a pregnant woman or can affect reproduction capacity. VT Doses Atropine 1% (Atropine) should be given to a pregnant woman only if clearly needed.

Contraindication

Glaucoma, chronic respiratory disease, sick sinus syndrome, thyrotoxicosis, cardiac failure, pyloric stenosis, prostatic hypertrophy.

Acute Overdose

May cause hyperthermia, hypertension, increased respiratory rate, nausea and vomiting. May also lead to CNS stimulation. Severe intoxication may lead to CNS depression, coma, respiratory failure and death.
