सुरक्षा सलाह: इस दवा को अपने डॉक्टर के निर्देशानुसार ही लें। गोली को पूरा निगलें, चबाएं या तोड़ें नहीं। इसे भोजन के साथ या बिना भोजन के ले सकते हैं, लेकिन पेट की परेशानी से बचने के लिए भोजन के साथ लेना बेहतर है। इस दवा के साथ शराब न लें। जब तक आपको पता न चले कि यह दवा आपको कैसे प्रभावित करती है, तब तक वाहन न चलाएं। अपने डॉक्टर को हृदय, यकृत या मानसिक स्वास्थ्य समस्याओं के बारे में बताएं।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAtomoxetine is rapidly absorbed after oral administration, with peak plasma concentrations occurring approximately 1 to 2 hours after dosing. Food does not significantly affect the extent of absorption but may delay the time to peak concentration.
DistributionAtomoxetine is widely distributed in the body. It is highly bound to plasma proteins, primarily albumin.
Protein BindingApproximately 98% bound to plasma proteins.
MetabolismAtomoxetine is extensively metabolized in the liver, primarily by the cytochrome P450 2D6 (CYP2D6) enzyme. It undergoes oxidative metabolism to form 4-hydroxyatomoxetine, which is then glucuronidated. Poor metabolizers of CYP2D6 may have higher plasma concentrations.
Half-LifeThe elimination half-life of atomoxetine is approximately 5 hours in extensive metabolizers and up to 21 hours in poor metabolizers.
ExcretionAtomoxetine and its metabolites are primarily excreted in the urine (more than 80%) and to a lesser extent in feces.
BioavailabilityThe absolute bioavailability of atomoxetine after oral administration is approximately 63% in extensive metabolizers and higher in poor metabolizers.
Onset of ActionThe onset of therapeutic effects may take 2 to 4 weeks, with full benefits often seen after 4 to 6 weeks of treatment.
Peak Plasma Time1 to 2 hours after oral administration.
Duration of ActionThe effects last for approximately 24 hours, allowing for once-daily dosing.

How It Works

Atomoxetine is a selective norepinephrine reuptake inhibitor (SNRI). It works by blocking the reuptake of norepinephrine into presynaptic neurons, thereby increasing the concentration of norepinephrine in the synaptic cleft. This enhances noradrenergic neurotransmission in the prefrontal cortex, which is thought to improve attention and reduce impulsivity and hyperactivity in ADHD.

Mechanism Steps

1
Binding to norepinephrine transporter: Atomoxetine selectively binds to the presynaptic norepinephrine transporter (NET) in the brain.
2
Inhibition of reuptake: It inhibits the reuptake of norepinephrine into presynaptic neurons, increasing its availability in the synaptic cleft.
3
Enhanced noradrenergic transmission: The increased norepinephrine levels enhance noradrenergic signaling in the prefrontal cortex, which is associated with improved attention and impulse control.
