Pam uses


DESCRIPTION

Chemical name: 2-formyl-1-methylpyridinium chloride oxime. Available in the United States as Pam for Injection (PROTOPAM Chloride), Pam chloride is frequently referred to as 2-PAM Chloride.

Structural formula:

C7H9CIN2O M.W. 172.61

Pam chloride occurs as an odorless, white, nonhygroscopic, crystalline powder which is soluble in water. Stable in air, it melts between 215º and 225º C, with decomposition.

The specific activity of the drug resides in the 2-formyl-1-methylpyridinium ion and is independent of the particular salt employed. The chloride is preferred because of physiologic compatibility, excellent water solubility at all temperatures, and high potency per gram, due to its low molecular weight.

Pam chloride is a cholinesterase reactivator.

Pam for intravenous injection or infusion is prepared by cryo-desiccation. Each vial contains 1000 mg of sterile Pam chloride, and sodium hydroxide to adjust pH, to be reconstituted with 20 mL of Sterile Water for Injection, USP. The pH of the reconstituted solution is 3.5 to 4.5. Intramuscular or subcutaneous injection may be used when intravenous injection is not feasible.

PROTOPAM structural formula

CLINICAL PHARMACOLOGY

The principal action of Pam chloride is to reactivate cholinesterase (mainly outside of the central nervous system) which has been inactivated by phosphorylation due to an organophosphate pesticide or related compound. The destruction of accumulated acetylcholine can then proceed, and neuromuscular junctions will again function normally. Pam chloride also slows the process of “aging” of phosphorylated cholinesterase to a nonreactivatable form, and detoxifies certain organophosphates by direct chemical reaction. The drug has its most critical effect in relieving paralysis of the muscles of respiration. Because Pam chloride is less effective in relieving depression of the respiratory center, atropine is always required concomitantly to block the effect of accumulated acetylcholine at this site. Pam chloride relieves muscarinic signs and symptoms, salivation, bronchospasm, etc., but this action is relatively unimportant since atropine is adequate for this purpose.

Pam has been studied in animals as an antidote against numerous organophosphate pesticides, chemicals, and drugs. Regardless of whether or not animal studies suggest that the organophosphate poison to which a particular patient has been exposed is amenable to treatment with Pam chloride, the use of Pam chloride should, nevertheless, be considered in any life-threatening situation resulting from poisoning by these compounds, since the limited and arbitrary conditions of pharmacologic screening do not always accurately reflect the usefulness of Pam chloride in the clinical situation.

CLINICAL STUDIES

There are no adequate and well controlled clinical studies that establish the effectiveness of Pam chloride as a treatment for poisoning with organophosphates having anticholinesterase activity. However, its use has been considered to be successful against poisoning with numerous pesticides, chemicals, and drugs.

Pharmacokinetics

Animal studies suggest that the minimum therapeutic concentration of Pam in plasma is 4 µg/mL; this level is reached in about 16 minutes after a single injection of 600 mg Pam chloride. In one study of healthy adult volunteers and patients self-poisoned with organophosphate compounds, a single intramuscular injection of 1000 mg of Pam chloride resulted in mean peak plasma levels of 7.5 ± 1.7 µg/mL and 9.9 ± 2.4 µg/mL, respectively. Time to reach the mean peak plasma levels in both groups was similar, 34 minutes in healthy adults and 33 minutes in poisoned patients. Mean half-life was about 3 hours in both groups.

Some evidence suggests that a loading dose followed by continuous intravenous infusion of Pam chloride may maintain therapeutic levels longer than short intermittent infusion therapy. In a cross-over study of seven healthy adults (18 – 50 years) a short intravenous infusion dose of 16 mg/kg over 30 minutes was compared to an intravenous loading dose of 4 mg/kg over 15 minutes, followed by 3.2 mg/kg/hr for 3.75 hours (for a total dose of 16 mg/kg). Results showed that the mean time over which plasma levels were maintained above 4 µg/mL was prolonged in the volunteers who received a loading dose followed by continuous infusion as compared to those who received short infusion therapy (257.5 ± 50.5 min vs. 118.0 ± 52.1 min). Use of continuous intravenous infusion in adult patients with organophosphate poisoning has been described in several case reports, with and without loading doses. Infusion rates ranged from 400 – 600 mg/hr. In one case the blood levels were 11.6 – 13.7 µg /mL when given 400 mg/hr over 5 days (measured at 5, 10 and 18 hours). In another case following an initial loading dose of 1000 mg, blood levels were 11.79 µg /mL when given 500 mg/hr and 17.26 µg /mL when given 600 mg/hr. In the latter case the Pam elimination half-life was 4 hours. In two other cases blood levels were not measured.

Pam chloride is distributed throughout the extracellular water; its apparent volume of distribution at steady state has been reported to range from 0.60 to 2.7 L/kg. Pam chloride is not bound to plasma protein.

Pam chloride is relatively short acting and repeated doses may be needed, unless continuous intravenous infusion is selected. Simulations suggest that after a dose of 1000 mg given intravenously, concentrations fall below 4 µg/mL in about 1.5 hours. The short duration of action of Pam chloride and the necessity for repeated doses should be considered especially where there is any evidence of continuing absorption of the poison. The apparent half-life of Pam chloride is 74 to 77 minutes. The drug is rapidly excreted in the urine by renal tubular secretion, partly unchanged, and partly as a metabolite produced by the liver. After intramuscular administration of 1000 mg of Pam chloride, the renal clearance has been reported to be 7.2 ± 2.9 mL/min/kg in healthy volunteers and 3.6 ± 1.5 mL/min/kg in organophosphate-poisoned patients.

In one study of 11 organophosphate-poisoned pediatric patients (age, 0.8 to 18 years), an intravenous loading dose of 15-50 mg/kg (mean 29 mg/kg) of Pam chloride followed by a continuous infusion of 10-16 mg/kg/hr (mean 14 mg/kg/hr) over 12 to 43 hours (mean 27 ± 8 hours) resulted in an average steady state plasma concentration of 22.2 mg/L (6.9 to 47.4 mg/L) and an average body clearance of 0.88 L/kg/hr (0.28 to 2.20 L/kg/hr). After the continuous infusion was discontinued, determinations of the apparent volume of distribution and half-life ranged from 1.7 to 13.8 L/kg and from 2.4 to 5.3 hours, respectively.

INDICATIONS AND USAGE

Pam is indicated as an antidote:


The principal indications for the use of Pam are muscle weakness and respiratory depression. In severe poisoning, respiratory depression may be due to muscle weakness.

CONTRAINDICATIONS

There are no known absolute contraindications for the use of Pam. Relative contraindications include known hypersensitivity to the drug and other situations in which the risk of its use clearly outweighs possible benefit.

WARNINGS

Pam is not effective in the treatment of poisoning due to phosphorus, inorganic phosphates, or organophosphates not having anticholinesterase activity.

Pam is not indicated as an antidote for intoxication by pesticides of the carbamate class since it may increase the toxicity of carbaryl.

PRECAUTIONS

General

Pam has been well tolerated in most cases, but it must be remembered that the desperate condition of the organophosphate-poisoned patient will generally mask such minor signs and symptoms as have been noted in normal subjects.

Intravenous administration of Pam should be carried out slowly and, preferably, by continuous or intermittent infusion, since temporary worsening of cholinergic manifestations may occur if Pam is infused too rapidly. The intermittent infusion rate should not exceed 200 mg/minute. If intravenous administration is not feasible, intramuscular or subcutaneous injection should be used.

Pam should be used with great caution in treating organophosphate overdosage in cases of myasthenia gravis since it may precipitate a myasthenic crisis.

Because Pam is excreted in the urine, a decrease in renal function will result in increased blood levels of the drug. Thus, the dosage of Pam should be reduced in the presence of renal insufficiency.

Laboratory Tests

Treatment of organophosphate poisoning should be instituted without waiting for the results of laboratory tests. Red blood cell, plasma cholinesterase, and urinary paranitrophenol measurements (in the case of parathion exposure) may be helpful in confirming the diagnosis and following the course of the illness, although such tests may be normal in the face of clinically significant organophosphate poisoning. A reduction in red blood cell cholinesterase concentration to below 50% of normal has been seen only with organophosphate ester poisoning.

Drug Interactions

When atropine and Pam chloride are used together, the signs of atropinization may occur earlier than might be expected when atropine is used alone. This is especially true if the total dose of atropine has been large and the administration of Pam chloride has been delayed.

The following precautions should be kept in mind in the treatment of anticholinesterase poisoning, although they do not bear directly on the use of Pam chloride: since barbiturates are potentiated by the anticholinesterases, they should be used cautiously in the treatment of convulsions; morphine, theophylline, aminophylline, reserpine, and phenothiazine-type tranquilizers should be avoided in patients with organophosphate poisoning. Prolonged paralysis has been reported in patients when succinylcholine is given with drugs having anticholinesterase activity; therefore, it should be used with caution.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Because Pam chloride is indicated for short-term emergency use only, no investigations of its potential for carcinogenesis, mutagenesis, or impairment of fertility have been conducted by the manufacturer, or reported in the literature.

Pregnancy

Teratogenic Effects

Pregnancy Category C

Animal reproduction studies have not been conducted with Pam chloride. It is also not known whether Pam chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Pam chloride should be given to a pregnant woman only if clearly needed.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Pam chloride is administered to a nursing woman.

Pediatric Use

There are no adequate and well-controlled clinical trials that establish the effectiveness of Pam chloride in pediatric patients. Efficacy has been extrapolated from the adult population and is supported by nonclinical studies, pharmacokinetic studies in adults and experience in the pediatric population. As in adults, laryngospasm, cardiac arrest, tachycardia, and muscle rigidity or paralysis have been reported following rapid intravenous injection. Muscle fasciculations, apnea, and convulsions have also been reported.

Geriatric Use

Clinical studies of Pam did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

Forty to 60 minutes after intramuscular injection, mild to moderate pain may be experienced at the site of injection.

Pam chloride may cause blurred vision, diplopia and impaired accommodation, dizziness, headache, drowsiness, nausea, tachycardia, increased systolic and diastolic blood pressure, hyperventilation, and muscular weakness when given parenterally to normal volunteers who have not been exposed to anticholinesterase poisons. In patients, it is very difficult to differentiate the toxic effects produced by atropine or the organophosphate compounds from those of the drug.

Elevations in SGOT and/or SGPT enzyme levels were observed in 1 of 6 normal volunteers given 1200 mg of Pam chloride intramuscularly, and in 4 of 6 volunteers given 1800 mg intramuscularly. Levels returned to normal in about 2 weeks. Transient elevations in creatine phosphokinase were observed in all normal volunteers given the drug.

When atropine and Pam chloride are used together, the signs of atropinization may occur earlier than might be expected when atropine is used alone. This is especially true if the total dose of atropine has been large and the administration of Pam chloride has been delayed. Excitement and manic behavior immediately following recovery of consciousness have been reported in several cases. However, similar behavior has occurred in cases of organophosphate poisoning that were not treated with Pam chloride.

DRUG ABUSE AND DEPENDENCE

Pam is not subject to abuse and possesses no known potential for dependence.

OVERDOSAGE

Manifestations of Overdosage

Observed in normal subjects only: dizziness, blurred vision, diplopia, headache, impaired accommodation, nausea, slight tachycardia. In therapy it has been difficult to differentiate side effects due to the drug from those due to the effects of the poison.

DOSAGE AND ADMINISTRATION

Organophosphate Poisoning

Treatment should include general supportive care, atropinization, and decontamination, in addition to the use of Pam. Treatment is most effective if initiated immediately after poisoning. Administration of Pam should be carried out slowly and, preferably, by infusion. If intravenous administration is not feasible, intramuscular or subcutaneous injection should be used. Generally, little is accomplished if Pam is given more than 36 hours after termination of exposure to the poison. When the poison has been ingested, it is particularly important to take into account the likelihood of continuing absorption from the lower bowel since this constitutes new exposure and fatal relapses have been reported after initial improvement. In such cases, additional doses of Pam may be needed every three to eight hours. In effect, the patient should be “titrated” with Pam as long as signs of poisoning recur. As in all cases of organophosphate poisoning, care should be taken to keep the patient under observation for at least 48 to 72 hours.

If dermal exposure has occurred, clothing should be removed and the hair and skin washed thoroughly with sodium bicarbonate or alcohol as soon as possible.

Supportive care, including airway management, respiratory and cardiovascular support, correction of metabolic abnormalities, and seizure control, may be necessary in cases of severe organophosphate poisoning.

Atropine should be given as soon as possible after hypoxemia is improved. Atropine should not be given in the presence of significant hypoxia due to the risk of atropine-induced ventricular fibrillation. In adults, atropine may be given intravenously in doses of 2 to 4 mg. This should be repeated at 5- to 10-minute intervals until full atropinization or signs of atropine toxicity appear (delirium, hyperthermia, muscle twitching).

Some degree of atropinization should be maintained for at least 48 hours, and until any depressed blood cholinesterase activity is reversed.

Use of morphine, theophylline, aminophylline, reserpine, and phenothiazine-type tranquilizers should be avoided in patients with organophosphate poisoning. Prolonged paralysis has been reported in patients when succinylcholine is given with drugs having anticholinesterase activity; therefore, it should be used with caution.

After the effects of atropine become apparent, Pam may be administered.

Symptoms Of Nerve Agent And Insecticide Poisoning

Pam dosing is based, in part, on the severity of symptoms of nerve agent intoxication. These symptoms include the following:

MILD symptoms:


SEVERE symptoms:

Symptoms in INFANTS AND YOUNG CHILDREN:

* These symptoms are sometimes observed in healthy infants and young children. In this age group, these symptoms are less reliable than other symptoms listed. Symptoms must be considered collectively when nerve agent or pesticide exposure is known or suspected.

** Infants may become drowsy or unconscious, with muscle floppiness rather than muscle twitching, soon after exposure to nerve agents or pesticides.

ADULT DOSING

ADULT INTRAVENOUS DOSING:

Refer to the Preparation for Administration section for instructions on reconstitution and dilution of Pam that result in a 10-20 mg/mL solution for intravenous infusion.

Inject an initial dose of 1000 to 2000 mg of Pam, preferably as an infusion in 100 mL of normal saline, over a 15- to 30-minute period. If this is not practical or if pulmonary edema is present, the dose should be given slowly by intravenous injection, as a 50 mg/mL solution in water (e.g., 1000 mg in 20 mL). A second dose of 1000 to 2000 mg may be indicated after about one hour if muscle weakness has not been relieved. Additional doses may be given every 10-12 hours if muscle weakness persists.

Intravenous administration of Pam should be carried out slowly and, preferably, by continuous or intermittent infusion, since temporary worsening of cholinergic manifestations (i.e. tachycardia, cardiac arrest, laryngospasm, and muscle rigidity or paralysis) may occur if Pam is infused too rapidly. The intermittent infusion rate should not exceed 200 mg/minute. If intravenous administration is not feasible, intramuscular or subcutaneous injection should be used.

Evidence suggests that a loading dose followed by continuous intravenous infusion of Pam may maintain therapeutic levels longer than traditional short intermittent infusions therapy.

ADULT INTRAMUSCULAR DOSING:

Refer to the Preparation for Administration section for instructions on reconstitution of Pam that result in an approximate 300 mg/mL solution for intramuscular administration.

Intramuscular dosing in adults should be based on the severity of clinical symptoms.

PEDIATRIC INTRAVENOUS DOSING

Refer to the Preparation for Administration section for instructions on reconstitution and dilution of Pam that result in 10-20 mg/mL solution for intravenous infusion.

Pam can be given as intermittent intravenous infusions or as a loading dose followed by continuous intravenous infusion, depending upon the patient’s clinical condition. The specific dose given should depend upon the severity of the symptoms.

Loading Dose Following By Continuous Infusion

Administer a loading dose of 20-50 mg/kg over 15-30 minutes followed by a continuous infusion of 10-20 mg/kg/hour.

Intermittent Infusion Dosing

Administer an initial intermittent infusion of 20-50 mg/kg (not to exceed 2000 mg/dose) over 15-30 minutes. A second dose of 20-50 mg/kg may be indicated after about one hour if muscle weakness has not been relieved. Repeat dosing is permissible every 10-12 hours as needed.

If it is not practical to administer intermittent or continuous intravenous infusions, or if pulmonary edema is present, the 20-50 mg/kg dose should be given slowly (over not less than five minutes) by intravenous injection as a 50 mg/mL solution in water. Additional doses may be given every 10-12 hours if muscle weakness persists.

PEDIATRIC INTRAMUSCULAR DOSING

Refer to the Preparation for Administration section for instructions on reconstitution of Pam that result in an approximate 300 mg/mL solution for intramuscular administration.

Intramuscular injections in children should be administered in the anterolateral aspect of the thigh to avoid the nerve, artery and vein, as well as the femur.

Pharmacokinetic modeling using published data from the scientific literature was conducted to derive intramuscular dosing recommendations in the pediatric population. The specific intramuscular dose of Pam should depend upon the severity of the symptoms.

Anticholinesterase Overdosage

As an antagonist to such anticholinesterases as neostigmine, pyridostigmine, and ambenonium, which are used in the treatment of myasthenia gravis, Pam may be given in a dosage of 1000 to 2000 mg intravenously followed by increments of 250 mg every five minutes.

Preparation for Administration

Pam is supplied as 1000 mg single-dose vials for injection.

For INTRAVENOUS infusion: Reconstitute a single Pam 1000 mg vial by adding 20 mL of Sterile Water for Injection, USP, which results in a 50 mg/mL concentration.

The solution should further be diluted with Normal Saline for Injection, USP to achieve a concentration of 10 to 20 mg/mL (e.g. 1000 mg in 100 mL or 2000 mg in 100 mL).

For fluid restricted patients or for rapid administration (over at least 5 min), a maximum concentration of 50 mg/mL may be used.

For INTRAMUSCULAR injection: Reconstitute a single Pam 1000 mg vial by adding 3.3 mL of Sterile Water for Injection, USP for an approximate concentration of 300 mg/mL.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Discard unused solution after a dose has been withdrawn.

Frequently asked Questions

Can i drive or operate heavy machine after consuming Pam?

Depending on the reaction of the Pam after taken, if you are feeling dizziness, drowsiness or any weakness as a reaction on your body, Then consider Pam not safe to drive or operate heavy machine after consumption. Meaning that, do not drive or operate heavy duty machines after taking the capsule if the capsule has a strange reaction on your body like dizziness, drowsiness. As prescribed by a pharmacist, it is dangerous to take alcohol while taking medicines as it exposed patients to drowsiness and health risk. Please take note of such effect most especially when taking Primosa capsule. It's advisable to consult your doctor on time for a proper recommendation and medical consultations.

Is Pam addictive or habit forming?

Medicines are not designed with the mind of creating an addiction or abuse on the health of the users. Addictive Medicine is categorically called Controlled substances by the government. For instance, Schedule H or X in India and schedule II-V in the US are controlled substances.

Please consult the medicine instruction manual on how to use and ensure it is not a controlled substance.In conclusion, self medication is a killer to your health. Consult your doctor for a proper prescription, recommendation, and guidiance.
