Bacnorm

Bacnorm Uses, Dosage, Side Effects, Food Interaction and all others data.

Bacnorm blocks dopamine receptors and in higher doses, it also blocks serotonin receptors in chemoreceptor trigger zone of the CNS. It enhances the response to acetylcholine of tissue in upper GI tract causing enhanced motility and accelerated gastric emptying w/o stimulating gastric, biliary, or pancreatic secretions. It also increases lower esophageal sphincter tone.

Bacnorm increases gastric emptying by decreasing lower esophageal sphincter (LES) pressure. It also exerts effects on the area postrema of the brain, preventing and relieving the symptoms of nausea and vomiting. In addition, this drug increases gastrointestinal motility without increasing biliary, gastric, or pancreatic secretions.

Because of its antidopaminergic activity, metoclopramide can cause symptoms of tardive dyskinesia (TD), dystonia, and akathisia, and should therefore not be administered for longer than 12 weeks.

How Bacnorm works

Bacnorm causes antiemetic effects by inhibiting dopamine D2 and serotonin 5-HT3 receptors in the chemoreceptor trigger zone (CTZ) located in the area postrema of the brain. Administration of this drug leads to prokinetic effects via inhibitory actions on presynaptic and postsynaptic D2 receptors, agonism of serotonin 5-HT4 receptors, and antagonism of muscarinic receptor inhibition. This action enhances the release of acetylcholine, causing increased lower esophageal sphincter (LES) and gastric tone, accelerating gastric emptying and transit through the gut. Bacnorm antagonizes the dopamine D2 receptors. Dopamine exerts relaxant effect on the gastrointestinal tract through binding to muscular D2 receptors.

Should be taken on an empty stomach. Take ½ hr before meals.

Side Effects

Extrapyramidal symptoms (usually acute dystonic reactions); parkinsonism; tardive dyskinesia; restlessness, drowsiness, dizziness, anxiety, confusion, tremor; hallucinations (rare); depression w/ suicidal ideation; hypotension, HTN, GI disturbances, dyspnoea, visual disturbances, urinary frequency and incontinence, headache; hypersensitivity reactions (rash, bronchospasm, angioedema); galactorrhoea or related disorders; blood disorders; transient increase in plasma-aldosterone concentration. IV: Cardiac conduction disorders, transient flushing of face and upper body (high dose).

Toxicity

The rat oral LD50 of metoclopramide is 750 mg/kg.

Some symptoms of an overdose with metoclopramide include drowsiness, disorientation, and extrapyramidal reactions. Drugs that manage Parkinson's disease or anticholinergic drugs or antihistamines with anticholinergic properties should be employed to treat extrapyramidal symptoms. Normally, these symptoms subside within 24 hours. Unintentional overdose in infants receiving the oral solution of metoclopramide resulted in seizures, extrapyramidal symptoms, in addition to a lethargic state.

In addition, methemoglobinemia has been found to occur in premature and full-term neonates after a metoclopramide overdose. Intravenous methylene blue may treat metoclopramide-associated methemoglobinemia. It is important to note that methylene blue administration may lead to hemolytic anemia in patients who suffer from G6PD deficiency, which can result in fatality. Dialysis has not been shown to be effective in sufficiently eliminating metoclopramide in an overdose situation due to low plasma distribution of this drug.

Precaution

Patients with underlying neurological conditions, cardiac conduction disturbances, uncorrected electrolyte imbalance, bradycardia. Renal and hepatic impairment. Elderly, childn. Pregnancy and lactation.

Interaction

Antagonistic effect with anticholinergics and morphine derivatives. Potentiation of sedative effects with CNS depressants. Additive effect with other neuroleptics on the occurrence of extrapyramydal disorders. May increase the risk of serotonin syndrome with serotonergic drugs (e.g. SSRIs). May decrease digoxin bioavailability. May increase ciclosporin bioavailability. May prolong the neuromuscular blocking effect of mivacurium and suxamethonium. Increased exposure levels with strong CYP2D6 inhibitors (e.g. fluoxetine). May reduce plasma concentration of atovaquone.

Food Interaction

  • Avoid alcohol.
  • Take before a meal. Co-administration with food decreases bioavailability - take 30 minutes before meals.

[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.

Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.

Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Bacnorm Hypertension interaction

[Moderate] In a study involving patients with essential hypertension, intravenously administered metoclopramide was shown to induce the release of catecholamines.

Therapy with metoclopramide should be administered cautiously in patients with hypertension because of potential increases in blood pressure.

Volume of Distribution

The volume of distribution of metoclopramide is approximately 3.5 L/kg. This implies a high level of tissue distribution. Bacnorm crosses the placental barrier and can cause extrapyramidal symptoms in the fetus.

Elimination Route

Bacnorm is rapidly absorbed in the gastrointestinal tract with an absorption rate of about 84%. The bioavailability of the oral preparation is reported to be about 40.7%, but can range from 30-100%.

Nasal metoclopramide is 47% bioavailable. A 15mg dose reaches a Cmax of 41.0 ng/mL, with a Tmax of 1.25 h, and an AUC of 367 ng*h/mL.

Half Life

The mean elimination half-life of metoclopramide in people with healthy renal function ranges from 5 to 6 hours but is prolonged in patients with renal impairment. Downward dose adjustment should be considered.

Clearance

The renal clearance of metoclopramide is 0.16 L/h/kg with a total clearance of 0.7 L/h/kg. Clinical studies showed that the clearance of metoclopramide may be reduced by up to 50% in patients with renal impairment. After high intravenous doses, total metoclopramide clearance ranged from 0.31 to 0.69 L/kg/h.

Elimination Route

About 85% of an orally administered dose was measured in the urine within 72 hours during a pharmacokinetic study. An average of 18% to 22% of 10-20 mg dose was recovered as free drug within 3 days of administration.

Pregnancy & Breastfeeding use

Category B: Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1st trimester (and there is no evidence of a risk in later trimesters).

Contraindication

GI haemorrhage, mechanical obstruction or GI perforation; confirmed or suspected pheochromocytoma; history of neuroleptic or metoclopramide-induced tardive dyskinesia; epilepsy, Parkinson's disease; history of methaemoglobinaemia with metoclopramide or of NADH cytochrome-b5 deficiency. Concomitant use with levodopa or dopaminergic agonists.

Acute Overdose

Symptoms: Extrapyramidal disorders, drowsiness, decreased level of consciousness, confusion, hallucination, cardiorespiratory arrest.

Management: Symptomatic treatment with continuous monitoring of CV and resp functions. In case of extrapyramidal symptoms, treatment is symptomatic (benzodiazepines in childn and/or anticholinergic antiparkinsonian medicinal products in adults).
