What is Waklert 150 mg

Waklert 150 mg is a drug used to treat excessive daytime sleepiness. It contains Armodafinil, which helps promote wakefulness by affecting certain brain chemicals involved in regulating the sleep–wake cycle. This tablet is recommended for patients suffering from sleep-related disorders such as Narcolepsy, Obstructive Sleep Apnoea, Shift Work Sleep Disorder, etc. For people who find it difficult to stay awake at work and experience excessive daytime sleepiness, this medicine may be prescribed by the doctor based on the symptoms as the effects last for around 14 hours. A single tablet is recommended to be taken once a day.

How Waklert 150 mg Works

Waklert 150 mg is a wakefulness-promoting medicine that helps improve alertness and reduce excessive daytime sleepiness. Although its exact mechanism is not fully understood, Armodafinil is believed to influence neurotransmitters involved in regulating the sleep–wake cycle, helping improve alertness and reduce excessive daytime sleepiness. Armodafinil is the R-enantiomer (active isomer) of Modafinil and generally has a longer duration of action. The effects of Armodafinil typically last for around 14 hours. For persons working in late-night shifts or rotational shifts, this medicine may be prescribed.

It helps reduce excessive daytime sleepiness and improves alertness during normal waking hours.

Dosage

Frequently Asked Questions (FAQs)

1. Is Waklert stronger than Modalert?

Though both the drugs Waklert and Modalert are used for the treatment of sleep disorders, the effects of this medicine are slightly stronger than that of Modalert. Waklert contains Armodafinil, the R-enantiomer (active isomer) of Modafinil (the ingredient in Modalert). According to a study, Armodafinil maintained higher plasma concentrations later in the day in healthy subjects as compared to Modafinil. As a result, the different pharmacokinetic profile of armodafinil may result in improved wakefulness throughout the day in patients with excessive sleepiness compared with modafinil.

2. How long does it take for Waklert 150 mg to kick in?

It takes anywhere around 1 to 2 hours for the effects of Waklert to kick in. According to a 2012 study, peak plasma concentrations are reached in approximately 2 hours when the drug is taken on an empty stomach.
