Clonazepam +
Escitalopram Tablet

Mechanism

The pharmacodynamic properties of clonazepam are common among benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects . Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absence seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations, as well as irregular spikes and waves . The agent can also decrease the frequency, amplitude, duration, and spread of discharge in minor motor seizures. Generalized EEG abnormalities are more readily suppressed by clonazepam than are focal EEG abnormalities such as focal spikes . Clonazepam has beneficial effects in generalized and focal epilepsies. Belongs to a class of medications called selective serotonin re-uptake inhibitors (SSRIs). These agents cause an increase in serotonin levels in neuronal synapses by preventing the re-uptake of serotonin (5-HT) into the presynaptic terminals of serotonergic neurons. As compared to other SSRIs, it appears to have a relatively quick onset of effect due to its potency. SSRIs as a class have been associated with abnormal bleeding, particularly in patients receiving concomitant therapy with other medications affecting hemostasis, and with the development of serotonin syndrome. Use escitalopram with caution in patients with a higher-than-baseline risk of bleeding and in patients receiving concomitant therapy with other serotonergic drugs. Escitalopram may also cause a discontinuation syndrome with abrupt removal of the drug, and should be slowly tapered if discontinuation of therapy is warranted.

Pharmacokinetics

• Absorption: Both drugs are well absorbed orally with good bioavailability.
• Distribution: Widely distributed in body tissues and cross the blood-brain barrier.
• Metabolism: Escitalopram is metabolized via CYP enzymes, while Clonazepam undergoes hepatic metabolism.
• Elimination: Excreted mainly via urine as metabolites.

Side Effects

• Drowsiness
• Dizziness
• Nausea
• Fatigue
• Dependence (long-term use)

Contraindication

• Concurrent use with MAO inhibitors

Interaction

• Avoid alcohol (increased sedation)
• Contraindicated with MAO inhibitors
• Caution with CNS depressants
• Risk of serotonin syndrome with SSRIs/SNRIs

Warning and Precautions
