How Atrop Pc works

Atropine binds to and inhibit muscarinic acetylcholine receptors, producing a wide range of anticholinergic effects.

The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation. Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days.

Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10.

Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive. High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.

Dosage

Atrop Pc 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

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.

The intraperitoneal LD₅₀ in rats is 2g/kg and 65mg/kg in mice. The subcutaneous LD₅₀ in rats is 147mg/kg and >3500mg/kg in mice. The oral LD₅₀ in mice is 1680mg/kg. In humans, the oral TDLO in men is 9mg/kg/2W and in women is 14mg/kg/13D.

Patients experiencing an overdose of prednisolone may present with gastrointestinal disturbances, insomnia, and restlessness. Overdose of oral prednisolone may be treated by gastric lavage or inducing vomiting if the overdose was recent, as well as supportive and symptomatic therapy. Chronic overdosage may be treated by dose reduction or treating patients on alternate days. An overdose by the ophthalmic route is not expected to cause problems.

Precaution

Reflux oesophagitis; elderly; infants and children; Pregnancy.

Interaction

Additive anticholinergic effects with quinidine, antidepressants and some antihistamines.

Volume of Distribution

A 0.15mg/kg dose of prednisolone has a volume of distribution of 29.3L, while a 0.30mg/kg dose has a volume of distribution of 44.2L.

Elimination Route

Atropine is rapidly and well absorbed after intramuscular administration. Atropine disappears rapidly from the blood and is distributed throughout the various body tissues and fluids.

Oral prednisolone reaches a C_max of 113-1343ng/mL with a T_max of 1.0-2.6 hours. Oral prednisolone is approximately 70% bioavailable.

Half Life

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

Prednisolone has a plasma half life of 2.1-3.5 hours. This half life is shorter in children and longer in those with liver disease.

Clearance

A 0.15mg/kg dose of prednisolone has a clearance of 0.09L/kg/h, while a 0.30mg/kg dose has a clearance of 0.12L/kg/h.

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.

Prednisolone is over 98% eliminated in 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. 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.

Storage Condition

Store atropine at room temperature between 20 to 25° C. Store away from heat, moisture, and light. Keep atropine out of the reach of children.
