Pralam
Pralam Uses, Dosage, Side Effects, Food Interaction and all others data.
Pralam is a triazolo analogue of the 1,4-benzodiazepine class of drugs. It is an anxiolytic with hypnotic and anticonvulsive properties. Pralam is presumed to produce its effects via interacting with the Gamma Aminobutyric Acid (GABA) - benzodiazepine receptor complex. Like all benzodiazepines, it causes a dose related CNS depressant activity varying from mild impairment of task performance to hypnosis.
Pralam is indicated to treat anxiety and panic disorders. The mechanism by which its cell receptor interactions translate to a clinical effect is not known.
Pralam exerts its effects through interaction with BNZ-1, BNZ-2, and GABA-A receptors. Pralam binding to BNZ-1 is thought to influence sedation and anti-anxiety, BNZ-2 may influence memory, coordination, muscle relaxation, and anticonvulsive activity, and GABA-A may calm patients by increasing the affinity of GABA-A receptors for GABA.
The metabolism of alprazolam is mediated largely through the action of CYP3As and so alprazolam is contraindicated with CYP3A inhibitors such as ketoconazole and itraconazole.

How Pralam works
Pralam is a triazolobenzodiazepine used to treat certain anxiety and panic disorders. Pralam acts on benzodiazepine receptors BNZ-1 and BNZ-2. The active metabolites 4-hydroxyalprazolam acts on these receptors with 0.20 times the potency of alprazolam and alpha-hydroxyalprazolam acts on these receptors with 0.66 times the potency.
The effect of alprazolam on BNZ-1 mediates the sedation and anti-anxiety effects of the drug while the action on BNZ-2 mediates effects on memory, coordination, muscle relaxation, and anticonvulsive activity.
Pralam also couple with GABA-A receptors to enhance GABA binding to its receptor. This interaction mediates inhibition of the nervous system and results in a calming effect.
The molecular mechanisms as well as the clinical effects of alprazolam have both been well demonstrated, however the means by which the molecular mechanism translates to a clinical effect is still not understood.
Dosage
Pralam dosage
Treatment should be initiated with a dose of 0.25 to 0.5 mg three times daily. Depending on the response, dose may
be increased at intervals of 3 to 4 days in increments of no more than 1 mg per day. The maximum dose should not
exceed 4 mg/day. Occasional patients with panic disorder may need as much as 10 mg a day to achieve a
successful response and in these cases periodic reassessment and consideration of dosage adjustment is required.
Dosage should be individualized for maximum beneficial effect with a lowest possible dose. If side-effects occur at
starting dose, dose may be lowered. When discontinuing therapy, dosage should be reduced gradually by no more
than 0.5 mg every three days.
In elderly patients or in patients with advanced liver disease, the usual starting dose is 0.25 mg, two or three times
daily and may be gradually increased if needed and tolerated. Safety and effectiveness of Pralam in individuals
below 18 years of age have not been established.
Pralam XR 1 should be administered once daily, preferably in the morning by patients who are on multiple dosage
regimen of Pralam 0.25/0.5 mg. The tablets should be taken intact, they should not be chewed, crushed, or broken.
Side Effects
Side effects, if occur, are generally observed at the beginning of therapy and usually disappear upon continued medication. The most frequent side effects are drowsiness and light headedness. The other side effects, that may occur include depression, headache, confusion, dry mouth, constipation etc.
Toxicity
Pralam overdose can present as sleepiness, confusion, poor coordination, slow reflexes, coma, and death. Taking alprazolam with alcohol lowers the threshold for overdose. Patients should have their respiration, pulse, and blood pressure monitored. Patients can be treated by gastric lavage and intravenous fluids.. If hypotension occurs, patients may be treated with vasopressors. In known, or suspected overdoses, patients can be given the benzodiazepine receptor antagonist flumazenil in addition to other methods of management.
Oral LD50 in rats is 331-2171mg/kg.
Pralam is a pregnancy category D teratogen meaning there is evidence of risk to the fetus of a mother taking alprazolam but in some cases the benefit may outweigh the risk. Children born to these mothers are also at risk of withdrawal symptoms, flaccidity, and respiratory issues.
Benzodiazepines are expressed in human breast milk and so nursing is generally not recommended in mothers taking alprazolam.
Pralam is not associated with carcinogenicity, mutagenicity, or impairment of fertility.
Precaution
Because Pralam may produce psychological and physical dependence, increment of dose or abrupt discontinuation of Pralam therapy should not be done without physician's advice. Duration of therapy must be determined by the physicians. Pralam should be administered with caution to patients with hepatic or renal disease, chronic pulmonary insufficiency or sleep apnea.
Interaction
Pralam produces additive CNS depressant effects when co-administered with other psychotropic medications, anticonvulsants, antihistaminics, ethanol and other drugs which themselves produce CNS depression.
Food Interaction
- Avoid alcohol. Alcohol may potentiate the CNS depressant effects of this drug.
- Avoid grapefruit products.
- Limit caffeine intake.
- Take with or without food. Food increases the Cmax of extended release alprazolam by 25%, but the AUC and half life are not affected.
[Moderate] GENERALLY AVOID: The pharmacologic activity of oral midazolam, triazolam, and alprazolam may be increased if taken after drinking grapefruit juice.
The proposed mechanism is CYP450 3A4 enzyme inhibition.
In addition, acute alcohol ingestion may potentiate CNS depression and other CNS effects of many benzodiazepines.
Tolerance may develop with chronic ethanol use.
The mechanism may be decreased clearance of the benzodiazepines because of CYP450 hepatic enzyme inhibition.
Also, it has been suggested that the cognitive deficits induced by benzodiazepines may be increased in patients who chronically consume large amounts of alcohol.
MANAGEMENT: The manufacturer recommends that grapefruit juice should not be taken with oral midazolam.
Patients taking triazolam or alprazolam should be monitored for excessive sedation.
Alternatively, the patient could consume orange juice which does not interact with these drugs.
Patients should be advised to avoid alcohol during benzodiazepine therapy.
Pralam Drug Interaction
Moderate: duloxetine, duloxetine, escitalopram, escitalopram, pregabalin, pregabalin, metoprolol, metoprololUnknown: amphetamine / dextroamphetamine, amphetamine / dextroamphetamine, aspirin, aspirin, omega-3 polyunsaturated fatty acids, omega-3 polyunsaturated fatty acids, cyanocobalamin, cyanocobalamin, ascorbic acid, ascorbic acid, cholecalciferol, cholecalciferol
Volume of Distribution
Volume of distribution following oral administration is 0.8-1.3L/kg. Pralam crosses the blood-brain barrier.
Elimination Route
Oral bioavailability of a standard release tablet of alprazolam is 84-91% with a time to maximum concentration of 1.8 hours. A 1mg oral dose of alprazolam leads to a maximum plasma concentration of 12-22mcg/L. Pralam is rapidly absorbed in the gastrointestinal tract.
Data for the area under the curve and the effect of taking alprazolam with food are not readily available.
Half Life
11.2 hours in healthy patients. The half life is 16.3h in the elderly, 5.8-65.3h in patients with alcoholic liver disease, 9.9-40.4h in obese patients. The half life is 25% higher in Asian patients compared to Caucasians. Other studies have shown the half life to be 9-16h.
Clearance
Oral clearance is 0.90±0.21mL/min/kg but this increases to 2.13±0.54mL/min/kg when given with CYP3A inducers. Other studies have demonstrated a clearance of 0.70-1.5mL/min/kg.
Elimination Route
Pralam is mainly eliminated in the urine. A large portion of the dose is eliminated as unmetabolized alprazolam. 2
Pregnancy & Breastfeeding use
Pregnancy: Pralam has been categorized in pregnancy category D; that means, it should be avoided in pregnancy.
Lactation: Like other benzodiazepines, Pralam is assumed to be excreted in breast milk. Therefore, nursing should not be undertaken by mothers who must use Pralam.
Contraindication
Contraindicated in patients with hypersensitivity to alprazolam or other benzodiazepines. Pralam is also contraindicated in patients with myasthenia gravis, acute narrow angle glaucoma, during pregnancy and also in infants.
Special Warning
Use in Children: Safety and efficacy of Pralam in patients under the age of 18 years has not been established.
Acute Overdose
Manifestations of Pralam over dosage include somnolence, confusion, impaired coordination, diminished reflexes and coma. In such cases of over dosage general supportive measures should be employed along with immediate gastric lavage.
Interaction with other Medicine
The CNS-depressant action of Pralam may be aggravated by concomitant use of other psychotropic drugs, anticonvulsants, antihistaminics, alcohol and oral contraceptives.
Storage Condition
Pralam tablets should be stored in a cool and dry place, protected from light and moisture.
