How Motion Plus works

The mechanism of action of prochlorperazine has not been fully determined, but may be primarily related to its anti-dopaminergic effects. Prochlorperazine blocks the D2 dopamine receptors in the brain, which are somatodendritic autoreceptors. Inhibition of D2 receptor signaling results in the blockade of postsynaptic dopamine receptors in the mesolimbic system and an increased dopamine turnover. Nausea and vomiting are proposed to arise from peripheral or central stimulation of serotonin type 3 (5-HT3) and dopamine type 2 receptors, the predominant receptors expressed at the chemoreceptor trigger zone (CTZ). Prochlorperazine exerts antiemetic effects and was shown to inhibit apomorphine-induced vomiting by blocking D2 dopamine receptors in the CTZ..

Prochlorperazine may be administered without regards of meal.

Side Effects

As all paracetamol products, adverse drug reactions are rare (>1/10000, <1/1000) or very rare (<1/10000). Frequent adverse reactions at injection site have been reported during clinical trials (pain and burning sensation). Very rare cases of hypersensitivity reactions ranging from simple skin rash or urticaria to anaphylactic shock have been reported and require discontinuation of treatment. Cases of erythema, flushing, pruritus and tachycardia have been reported.

Drowsiness, jaw, neck, and back muscle spasms, fine worm-like tongue movements, rhythmic face, mouth, or jaw movements, slow or difficult speech, difficulty swallowing, restlessness and pacing, tremors, shuffling walk, skin rash, yellowing of the skin or eyes.

Toxicity

LD₅₀ and Overdose

Oral LD₅₀ in rats is 750 mg/kg. Intraperitoneal and subcutaneous LD₅₀ in mice are 191 mg/kg and 320 mg/kg, respectively. In placebo-controlled trials, there were increased incidences of mortality in elderly patients with dementia-related psychosis receiving antipsychotic medications. The risk of death in drug-treated patients was about 1.6 to 1.7 times that of placebo-treated patients. Deaths were largely resulting from cardiovascular, such as heart failure and sudden death, or infectious, such as pneumonia, conditions. Due to its antagonist action on dopamine receptors, prochlorperazine is associated with a risk for developing extrapyramidal symptoms such as tardive dyskinesia, which is a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements. This risk is also conferred on other antipsychotic agents that block dopamine receptors. It is proposed that increased duration of the drug treatment is likely thus increased total cumulative dose of antipsychotic drugs administered to the patient leads to increased risk for developing the syndrome and the likelihood that it will become irreversible. As with other antipsychotic agents, prochlorperazine is associated with a risk for causing neuroleptic malignant syndrome (NMS), which is a potentially fatal symptom complex, which is manifested as hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability.

There is no known antidote for prochlorperazine thus overdose treatment should be supportive and symptomatic. Overdose of prochlorperazine may produce dystonic reactions that involve extrapyramidal mechanism. To reduce these symptoms, antiparkinsonism drugs, barbiturates, or diphenhydramine may be used. Symptoms of central nervous system depression, such as somnolence or coma, may also be observed. Amphetamine, destroamphetamine, or caffeine and sodium benzoate may be used to induce stimulatory effects. In contrast, agitation and restlessness may also be seen in case of overdose. Other possible manifestations include convulsions, EKG changes and cardiac arrhythmias, fever, and autonomic reactions such as hypotension, dry mouth and ileus. Hypotension can be responded with the standard measures for managing circulatory shock.

Nonclinical Toxicology

In a rat developmental or reproductive toxicity study, abnormalities in both the reproductive measures and neurobehavioral testing were observed following administration of 25 mg/kg of prochlorperazine.

Use in specific populations

As the use of antipsychotic agents during the third trimester of pregnancy is associated with a risk for extrapyramidal and/or withdrawal symptoms following delivery, the use of prochlorperazine in pregnant patients is generally not recommended and it should be limited after careful consideration of the potential benefit of drug therapy justifying the potential risk to the fetus. Caution should be exercised when prochlorperazine is administered to a nursing mother. While lower doses of prochlorperazine is reported to be safe for elderly patients, caution is still advised, especially those with higher susceptibility to hypotension and neuromuscular reactions.

Precaution

Administration of Paracetamol in doses higher than recommended may result in hepatic injury, including the risk of severe hepatotoxicity and death. Do not exceed the maximum recommended daily dose of Paracetamol. Use caution when administering Paracetamol in patients with the following conditions: hepatic impairment or active hepatic disease, alcoholism, chronic malnutrition, severe hypovolemia (e.g., due to dehydration or blood loss), or severe renal impairment (creatinine clearance < 30 ml/min). There were infrequent reports of life-threatening anaphylaxis requiring emergent medical attention. Discontinue Paracetamol IV immediately if symptoms associated with allergy or hypersensitivity occurs. Do not use Paracetamol IV in patients with Paracetamol allergy.

Caution should be taken while performing tasks that require alertness, such as driving or using machinery. Use of alcohol can cause extreme drowsiness. This medication may increase sensitivity to sunlight. Prolonged sun exposure should be avoided and a sunscreen and protective clothing should be taken when anybody is exposed to the sun. This medication can reduce sweating making more susceptible to heat stroke.

Interaction

Alcohol, barbiturate & other sedatives may increase the CNS depressant action. Some drugs like Antacids, antiparkinson's drug, lithium may interfere the absorption of Prochlorperazine. This drug may interfere the plasma concentration of Propanolol, Phenobarbital.

Volume of Distribution

Volume of distribution is about 0.9L/kg. 10 to 20% of the drug is bound to red blood cells. Acetaminophen appears to be widely distributed throughout most body tissues except in fat.

In a preliminary pharmacokinetic study involving healthy volunteers, the mean apparent volume of distribution following intravenous administration of 6.25 mg and 12.5 mg prochlorperazine were approximately 1401 L and 1548 L, respectively. Prochlorperazine is reported to be distributed to most body tissues with high concentrations being distributed into liver and spleen. There is evidence that phenothiazines are excreted in the breast milk of nursing mothers.

Elimination Route

Following oral administration, prochlorperazine is reported to be well absorbed from the gastrointestinal tract. The onset of pharmacological action is about 30 to 40 minutes following oral administration and 10 to 20 minutes following intramuscular administration. The duration of action for all routes is about 3 to 4 hours. Following oral administration in healthy volunteers, the mean oral bioavailability was about 12.5%. In these patients, the time to reach the peak plasma concentrations was about 5 hours. Repeated oral dosing resulted in an accumulation of prochlorperazine and its metabolite. Following multiple twice daily dosing, the steady state of prochlorperazine was reached by 7 days.

Half Life

The half-life for adults is 2.5 h after an intravenous dose of 15 mg/kg. After an overdose, the half-life can range from 4 to 8 hours depending on the severity of injury to the liver, as it heavily metabolizes acetaminophen.

Following intravenous and single oral dose administration, the terminal elimination half live were 9 and 8 hours, respectively.

Clearance

Adults: 0.27 L/h/kg following a 15 mg/kg intravenous (IV) dose. Children: 0.34 L/h/kg following a 15 mg/kg intravenous (IV dose).

The mean plasma clearance (CL) of prochlorperazine following intravenous administration in healthy volunteers was approximately 0.98L/h x kg. The mean renal clearance was about 23.6 mL/h.

Elimination Route

Prochlorperazine is reported to be mainly excreted via the feces and bile. Low quantities of unchanged prochlorperazine and its metabolite were detectable in the urine.

Pregnancy & Breastfeeding use

Pregnancy Category C. There are no studies of intravenous Paracetamol in pregnant women; however, epidemiological data on oral Paracetamol use in pregnant women show no increased risk of major congenital malformations. Animal reproduction studies have not been conducted with IV Paracetamol and it is not known whether Paracetamol IV can cause fetal harm when administered to a pregnant woman. Paracetamol IV should be given to a pregnant woman only if clearly needed. There are no adequate and well-controlled studies with Paracetamol IV during labor and delivery; therefore, it should be used in such settings only after a careful benefit-risk assessment. While studies with Paracetamol IV have not been conducted, Paracetamol is secreted in human milk in small quantities after oral administration.

No evidence of adverse effects of this drug has been reported during pregnancy & lactation.

Contraindication

Paracetamol is contraindicated in patients with known hypersensitivity to its active ingredient or to any of the excipients in the intravenous formulation. Also contraindicated in patients with severe hepatic impairment or severe active liver disease

Hypersensitivity to prochlorperazine or any component of the formulation, severe CNS depression; coma; should not be used in children <2 years of age or <10 kg.

Special Warning

Pediatric Use: The safety and effectiveness of Paracetamol IV for the treatment of acute pain and fever in pediatric patients ages 2 years and older is supported by evidence from adequate and well-controlled studies of Paracetamol IV in adults.

Geriatric use: No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients.

Patients with Hepatic Impairment: Paracetamol is contraindicated in patients with severe hepatic impairment or severe active liver disease and should be used with caution in patients with hepatic impairment or active liver disease. A reduced total daily dose of Paracetamol may be warranted.

Patients with Renal Impairment: In cases of severe renal impairment (creatinine clearance < 30 ml/min), longer dosing intervals and a reduced total daily dose of Paracetamol may be warranted.
