Why nuvigil vs provigil

However, armodafinil may have longer-lasting effects compared to modafinil. In a week randomized, clinical trial, both armodafinil and modafinil improved sleepiness in subjects working the night shift. Results found that armodafinil and modafinil were comparable with similar safety scores. In a meta-analysis comparing armodafinil and modafinil for obstructive sleep apnea, both drugs were found to be effective for treating sleepiness. Patients taking either drug tolerated side effects and experienced improved daytime wakefulness.

Armodafinil has been shown to have higher plasma concentrations in the body later in the day. Higher armodafinil levels in the body may result in better wakefulness compared to modafinil. While either drug can be used as a treatment for excessive sleepiness, it is best to consult a doctor for medical advice. Currently, there are no definitive studies that say one is more effective than the other. Armodafinil is usually prescribed as a mg tablet taken once daily. It is widely available as a generic medication that is covered by Medicare and insurance plans.

This price can be brought down with a SingleCare discount card. Depending on your insurance plan, modafinil may be covered. In fact, Medicare and most insurance plans cover modafinil for approved purposes. At participating pharmacies, you can use a SingleCare savings card to save money. The most common side effects associated with armodafinil and modafinil are headache, nausea, dizziness, and insomnia.

Modafinil may be more likely to cause other side effects such as nervousness, nasal congestion rhinitis , diarrhea, and back pain. Both medications can also cause dry mouth, indigestion dyspepsia , and anxiety. Side effects related to weight loss can also occur. Some people who take armodafinil or modafinil may experience decreased appetite. Other rare but serious side effects include allergic reactions such as rash and shortness of breath. Psychiatric side effects such as depression or psychosis are also possible.

Seek medical attention if you experience these side effects. This may not be a complete list. Consult your doctor or pharmacist for possible side effects.

Provigil modafinil and Nuvigil armodafinil are stimulant -like drugs used to treat excessive sleepiness. There are generics available for Provigil but not for Nuvigil.

They are manufactured by the same company Cephalon and have the same effects. Armodafinil Nuvigil is an enantiopure drug ; it is the R-enantiomer of modafinil Provigil.

In other words, there is only a small difference in their chemical structure. Both Provigil and Nuvigil increase the release of monamines, specifically catecholamines norepinephrine and dopamine, from synaptic terminals. They also elevate hypothalamic histamine levels. In terms of chemical composition, armodafinil is an enantiomer of modafinil.

It is possible that enantiomers of drugs bind differently to receptors in the body and therefore have different effects. For example, one enantiomer of Naproxen is used to treat liver pain but another causes liver poisoning with no analgesic effects. However, in the case of modafinil Provigil and armodafinil Nuvigil , both drugs have similar effects on the body.

Since the two drugs are not chemically identical, the patent application for Nuvigil was filed and approved separately. The patent for Provigil has expired and generics are available. Both Provigil and Nuvigil are used to treat narcolepsy, obstructive sleep apnea and shift work disorder. In addition, Provigil may be prescribed to treat ADHD , mood disorders, depersonalization disorder, cognitive enhancement, fatigue, cocaine addiction, post- chemotherapy cognitive impairment, weight loss, as a doping agent and in military and law enforcement.

Nuvigil was being considered as treatment for jet lag, schizophrenia and depression but failed to meet FDA approval for all of these uses. This was a multi-centric, randomized, comparative, and double-blind parallel group, clinical trial conducted over 18 sites across India. Coprescriptions not interfering with the study drug evaluation were allowed.

The test formulation was earlier found to be bioequivalent to the US FDA-approved formulation of armodafinil, in 26 healthy Indian volunteers [ 11 ]. The tablets of armodafinil and modafinil were identical in shape, size, and color and were dispensed in coded, identical, and opaque packs to conceal identity and maintain blinding.

Patients were evaluated for sleepiness score based on Stanford sleepiness Scale SSS at baseline, 4 weeks, 8 weeks, and 12 weeks [ 12 ]. All the assessments were done in the morning hours at the end of three consecutive night shifts. The primary efficacy endpoint was proportion of patients showing at least 2 grades of improvement responder based on SSS in both groups.

A general and detailed systemic examination was performed for all patients during each study visit. Blood samples were collected at baseline and at the end of the study for complete hemograms, liver function tests, renal function tests, lipid profile, and fasting blood glucose levels. Electrocardiograms were performed for all patients at baseline and at the end of the study. Demographic and baseline characteristics were summarized using descriptive statistics. Within group and between-groups comparisons were done using -test.

Global assessment for efficacy and tolerability was done by comparing the proportion of patients showing excellent and good response against proportion of patients showing fair and poor response. For all statistical tests, a value of less than or equal to 0. Two hundred and eleven patients of SWSD were recruited with subjects in armodafinil group and subjects in the modafinil group Figure 1.

The baseline demographic parameters of both groups were comparable Table 2. Both modafinil and armodafinil significantly improved sleepiness grades as compared to baseline Figure 2. At the end of therapy, compliance in both modafinil group and armodafinil group was found to be good and comparable indicating adequate patient adherence to therapy. The intention-to-treat analysis showed that the adverse event incidences in modafinil The adverse effect profile of both drugs was found to be similar with headache, nausea, and dry mouth being the common adverse effects Table 3.

There were no serious adverse events reported during the study. No adverse effects on cognitive or psychomotor functions reported during the study.

No incidences of accidents or absenteeism from work were noted during the study period as assessed from patient history. However, the increased values were within normal limits. In both groups, electrocardiograms were within normal at baseline and after completion of therapy in all patients. One patient in each group opted to discontinue therapy due to adverse events.

The adverse events that led to discontinuation were palpitation, anxiety, hypertension, depression, nervousness, and depressed mood in a patient receiving armodafinil and vomiting along with dizziness in another patient receiving modafinil.

The safety profile of armodafinil was found to be similar to modafinil. Both modafinil and armodafinil caused a slight increase in liver enzymes, and armodafinil caused a slight increase in blood urea nitrogen. This was not of clinical significance as the increased values were within normal laboratory limits [ 13 ]. The use of R-enantiomer of modafinil avoids unnecessary use of S-isomer and exerts less metabolic load on the body. This was due initial faster elimination of the S-isomer of modafinil.

This pharmacokinetic advantage was claimed to translate into therapeutic benefit. A limitation of the present study is that the assessment of sleep latency and polysomnography throughout the nightshift could not be done due to unavailability of patients and investigators.

This prevented assessment of the clinical correlates of pharmacokinetic advantages of armodafinil [ 7 ]. Armodafinil was found to be safe and effective in the treatment of SWSD. The study including investigational products was sponsored by Emcure Pharmaceuticals Ltd. The authors received a research grant from Emcure Pharmaceuticals Ltd. The study was sponsored by and investigational products provided by Emcure Pharmaceuticals Ltd. Similarities Provigil and Nuvigil are surprisingly alike when you compare the two.

Affected by Food Intake While taking food alongside your dose of Modafinil or Armodafinil will likely delay the onset of its effects by hours, the overall bioavailability of both drugs remains unchanged [ 8 , 9 ]. Both drugs clearly worked, came with minimal side effects, and were well tolerated by patients. Here are the most common effects reported by countless test subjects [ 13 ]: Improved short-term memory Increased focus Elevated confidence i.

Pharmacokinetic Properties Remember the paper we quoted earlier that stated Armodafinil may lead to improved wakefulness? Nuvigil conversation starts to get interesting. If you compare both enantiomers of Modafinil, the properties are quite different from one another: The R-enantiomer has a half-life of hours, while the S-enantiomer has a half-life of hours [ 15 ].

The S-enantiomer has a three-fold shorter duration than the R-enantiomer, and is also eliminated 3x faster than the R-enantiomer [ 16 ]. The R-enantiomer has a three-fold higher affinity for the dopamine transporter than the S-enantiomer, and thus it is 3x more effective at inhibiting dopamine uptake [ 14 ]. Dosing Regimen The ideal Modafinil dosage and the ideal Armodafinil dosage are not the same. However, the best dose to take for experiencing cognitive enhancement from either drug is similar to the one used for their prescribed conditions: For Provigil i.

Side Effects and Safety Concerns Armodafinil vs. There are a number of contra-indications with both Armodafinil and Modafinil that you should know about [ 21 ]: Both drugs may reduce the effectiveness of medications lowering blood pressure such as propranolol , as they slightly elevate blood pressure due to their stimulant properties. Modafinil Cost Comparison If you do a price comparison of Provigil vs. In our opinion, buying the generic variant of these nootropics through a reputable and legitimate online Modafinil vendor like Buy Moda is the way to go In terms of the generic variants, we would suggest going with Modalert for Modafinil and Waklert for Armodafinil.

Which Nootropic is Better? Daily dosing is only meant for those with the medical conditions for which either Modafinil or Armodafinil are prescribed In more specific terms, we avoid exceeding doses a week with either Modafinil or Armodafinil. Modafinil The Verdict So what can we conclude from this Armodafinil vs. Modafinil side-by-side comparison? You can expect immense cognitive benefits with little to no side effects from both smart drugs The only major difference between the two is in how you respond to them.
