Arotril 1 mg

Description

Indications:

Arotril is primarily prescribed for the management of panic disorder, both with and without agoraphobia. Panic disorder is characterized by unexpected panic attacks, accompanied by persistent concerns about future episodes and their potential consequences.

In addition to treating panic disorder, Arotril is also indicated for the treatment of Lennox-Gastaut Syndrome (petit mal variant), akinetic seizures, and myoclonic seizures. It is particularly useful in cases where patients with absence seizures (petit mal) do not respond adequately to succinimides.

However, the long-term effectiveness of Arotril beyond 9 weeks has not been systematically evaluated in controlled clinical trials. For patients requiring extended treatment, healthcare providers should regularly assess the continued benefits of the medication.

Take the medication strictly as per the advice of a registered healthcare professional.

Pharmacology:

Clonazepam, the active ingredient in Arotril, belongs to the benzodiazepine class of medications, which exert several pharmacological effects, including anticonvulsant, sedative, muscle relaxant, and anxiolytic properties. These effects are mediated by enhancing GABAergic neurotransmission at inhibitory synapses, which increases the action of the neurotransmitter GABA on chloride ion flux across the postsynaptic membrane.

Animal studies also suggest that clonazepam may influence serotonin. Furthermore, both animal data and electroencephalographic (EEG) studies in humans have demonstrated clonazepam’s ability to suppress various types of paroxysmal brain activity, including spike-and-wave discharges observed in absence seizures (petit mal) and other generalized epileptic conditions.

Based on these findings, clonazepam has been found to be beneficial in treating both generalized and focal epilepsies.

Dosage & Administration:

Oral Dosage:

• Adults (Seizure Disorders): The starting dose for adults with seizure conditions should not exceed 1.5 mg per day, divided into three doses. The dose may be gradually increased by 0.5 to 1 mg every 3 days until the seizures are controlled or until side effects limit further dose increases. The recommended maintenance dose is individualized, with a maximum daily dose of 20 mg.

• Adults (Panic Disorder): The initial dose for panic disorder treatment is 0.25 mg, divided into two doses per day. After 3 days, the dose can be increased to 1 mg/day, which is the typical target dose for most patients.

• Pediatric Patients (Seizures): To minimize drowsiness in infants and children (up to 10 years or 30 kg), the starting dose should be 0.01 to 0.03 mg/kg/day, not exceeding 0.05 mg/kg/day. This should be divided into two or three doses per day.

Injection Dosage:

• Infants & Children: The recommended dose is 0.5 mg (half of a vial) given by slow IV injection or IV infusion.

• Adults: The recommended dose for adults is 1 mg (1 vial) by slow IV injection or IV infusion. This dose may be repeated as required, typically 1-4 mg is sufficient for reversal of status epilepticus.

Important Injection Information:
For IV injection, do not exceed a rate of 0.25-0.5 mg per minute, and the total dose should not surpass 10 mg. Always follow healthcare professional guidance for correct administration.

Take the medication strictly as per the advice of a registered healthcare professional.

Drug Interactions:

Arotril does not significantly affect the pharmacokinetics of phenytoin, carbamazepine, or phenobarbital. However, the impact of Arotril on the metabolism of other drugs remains unstudied.

---

Contraindications:

Arotril should not be used in patients with a known hypersensitivity to benzodiazepines or in those with significant liver disease (either clinical or biochemical). It can be used with caution in patients with open-angle glaucoma under appropriate treatment, but it is contraindicated in those with acute narrow-angle glaucoma.

---

Side Effects:

The most common side effects are related to central nervous system (CNS) depression. These include:

• Drowsiness (observed in about 50% of patients)
• Ataxia (approximately 30%)
• Behavioral changes in around 25% of patients

Other potential side effects include:

• Abnormal eye movements
• Tremors, confusion, and depression
• Amnesia, hallucinations, increased libido, and sleep disturbances (insomnia)
• Psychosis, palpitations, and vertigo can also occur.

---

Pregnancy & Lactation:

• Pregnancy: Clonazepam has been linked to congenital malformations in preclinical studies, and anticonvulsants are known teratogens. The drug should only be used during pregnancy if the potential benefits outweigh the risks. High doses during the third trimester may cause issues such as hypothermia, hypotonia, respiratory depression, and poor feeding in the neonate. Withdrawal symptoms have occasionally been reported in newborns.

• Lactation: Clonazepam passes into breast milk in small amounts. Breastfeeding should be avoided during treatment with Arotril.

---

Precautions & Warnings:

• Seizure Disorders: In patients with coexisting seizure disorders, Arotril may increase the risk of generalized tonic-clonic seizures, which may require adjusting other anticonvulsants.

• Concomitant Use of Valproic Acid: The combination of Arotril and valproic acid may induce absence status.

---

Use in Special Populations:

• Pediatric Use: Special care must be taken in infants and small children to manage increased salivation and maintain airway patency.

• Geriatric Use: Elderly patients are more sensitive to benzodiazepines, which may result in enhanced effects even at similar plasma concentrations.

• Renal Impairment: No dose adjustment is required for patients with renal impairment.

• Hepatic Impairment: In patients with liver cirrhosis, Arotril’s clearance may be reduced, which could necessitate dosage adjustments.

---

Overdose Effects:

Symptoms of Overdose include:

• Drowsiness, ataxia, and confusion
• Speech difficulty, abnormal eye movements, and nystagmus
• Severe cases can lead to apnoea, hypotension, and coma

Treatment involves:

• Supportive care, such as monitoring vital signs and addressing CNS or cardiorespiratory effects.
• In some cases, flumazenil, a benzodiazepine antagonist, may be used, but only under close medical supervision.

---

Storage Conditions:

Store Arotril in a dry place, away from direct light and heat, and ensure it is out of reach of children.
