MODAVIGIL 1 MODAVIGIL MODAFINIL CONSUMER MEDICINE INFORMATION WHAT IS IN THIS LEAFLET This leaflet answers some common questions about MODAVIGIL tablets. As this leaflet does not contain all the available information, it is important that you talk to your doctor or pharmacist. All medicines have risks and benefits. Your doctor has weighed the risks of you receiving MODAVIGIL ® against the benefits this medicine is expected to have for you. IF YOU HAVE ANY CONCERNS ABOUT TAKING THIS MEDICINE, ASK YOUR DOCTOR OR PHARMACIST. KEEP THIS LEAFLET. You may need to read it again. WHAT MODAVIGIL ® IS USED FOR MODAVIGIL ® is used to improve wakefulness in people with excessive daytime sleepiness associated with the medical condition known as narcolepsy or with Obstructive Sleep Apnoea/Hypopnoea Syndrome (OSAHS), or shift work sleep disorder (SWSD). In narcolepsy, there is a sudden and irresistible tendency to fall asleep during normal waking hours. This happens at unpredictable times, even when it is inappropriate or may be unsafe to do so. MODAVIGIL ® decreases this unwanted excessive daytime sleepiness. With OSAHS, daytime sleepiness may occur due to an interrupted night time sleep. MODAVIGIL ® only treats the symptom of sleepiness and does not treat the cause of OSAHS. Whilst taking MODAVIGIL ® you should continue with treatments intended to help manage your underlying medical condition, such as Continuous Positive Airway Pressure, unless your doctor tells you otherwise. If you have been diagnosed with moderate to severe chronic Shift Work Sleep Disorder (SWSD) and non-drug therapies have been unsuitable or unsuccessful, MODAVIGIL ® may be prescribed to keep you aw Leia o documento completo

The chemical structure is: * chiral centre The CAS registry number is 68693-11-8. DESCRIPTION Modafinil is a white to off-white, crystalline powder that is practically insoluble in water and cyclohexane. It is sparingly to slightly soluble in ethanol and acetone.

PHARMACOLOGY PHARMACODYNAMICS The precise mechanism(s) through which modafinil promotes wakefulness is unknown. Modafinil has wake-promoting actions but a pharmacological profile that is distinct from sympathomimetic amines, which increase wakefulness by other mechanisms. Modafinil does not bind to most of the potentially relevant receptors for sleep/wake regulation, including those for noradrenaline, serotonin, dopamine, GABA, adenosine, histamine-3 and benzodiazepines. Modafinil is not a direct- or indirect-acting dopamine receptor agonist and is inactive in several _in vivo_ preclinical models capable of detecting enhanced dopaminergic activity. _In vitro_, modafinil binds to the dopamine reuptake site with low affinity and causes an increase in extracellular dopamine, but no increase in dopamine release. Modafinil does not appear to be a direct or indirect α 1 -adrenergic agonist. Although modafin Leia o documento completo
