Market Information


For patients dealing with excessive sweating (hyperhidrosis) or drooling (sialorrhea), certain medications that affect the body's production of sweat and saliva can help manage these symptoms. Robinul and Cuvposa are two such drugs often prescribed for those conditions. They both have anticholinergic effects, which means they block certain nerve impulses to reduce fluid secretions in the body. Robinul, known generically as Glycopyrrolate, is a versatile medication used not only for hyperhidrosis but also other conditions like peptic ulcers and to reduce drooling in pediatric patients. On the other hand, Cuvposa is a brand name for liquid Glycopyrrolate specifically formulated to manage chronic severe drooling caused by neurologic conditions in children aged 3-16 years old.

What is Robinul?

Glycopyrrolate (the generic name for Robinul) was one of the initial drugs from the class of anticholinergic medications, which marked a significant development upon first being utilized in medical treatments. This medication was approved by the FDA in 1961. Robinul works as an antagonist to acetylcholine receptors, effectively reducing saliva and other secretions in the body. It is prescribed primarily for treating peptic ulcers and excessive drooling.

On the other hand, Cuvposa is another brand name of glycopyrrolate but has been specifically designed to treat chronic severe drooling caused by certain medical conditions (such as cerebral palsy) in children aged between 3 to 16 years old. While both Robinul and Cuvposa have similar effects on reducing bodily fluids, they are used differently based on patient needs with Cuvposa having a more specific target population than Robinul.

What conditions is Robinul approved to treat?

Robinul and Cuvposa are approved for the treatment of different medical conditions:

  • Robinul is typically used to reduce salivary, gastric, and pancreatic secretions, as well as decrease sweating. It's often utilized in preoperative preparation or to control overdoses of certain medications.
  • Cuvposa, on the other hand, is specifically used for chronic severe drooling caused by neurologic disorders in children aged 3 years and older.

How does Robinul help with these illnesses?

Robinul helps to manage excessive sweating (hyperhidrosis) by reducing the amount of acetylcholine available in the synapses. It does this by acting as an anticholinergic agent, which means it blocks acetylcholine from binding to its receptors on certain nerve cells. Acetylcholine is a neurotransmitter that plays an important role in multiple functions, including controlling sweat gland activity. Individuals with hyperhidrosis produce more sweat than necessary and Robinul can help limit these effects and stabilize their condition.

On the other hand, Cuvposa works similarly as it is also an anticholinergic medication but has been specifically approved for pediatric use to treat chronic severe drooling caused by neurologic conditions such as cerebral palsy. While both medications block acetylcholine resulting in decreasing bodily secretions, they are primarily used for managing different symptoms or disorders.

What is Cuvposa?

Cuvposa is a brand name for the drug glycopyrrolate, an anticholinergic medication that blocks the action of acetylcholine at muscarinic receptors in the body. By doing this, it decreases bodily secretions such as sweat and saliva. Cuvposa was approved by the FDA specifically to treat chronic severe drooling caused by neurologic conditions like cerebral palsy in children aged between 3-16 years old.

As an anticholinergic, Cuvposa does not affect serotonin or norepinephrine levels in any way which differentiates it from drugs like Robinul (another form of glycopyrrolate), used for treating peptic ulcers and reducing drooling post-surgery. The specific formulation and approval of Cuvposa allows it to be dosed once daily compared to multiple times with other forms of glycopyrrolate. This long-lasting effect can be beneficial especially when managing symptoms related to chronic diseases where ease of medication administration becomes crucial.

What conditions is Cuvposa approved to treat?

Cuvposa, a form of glycopyrrolate, is authorized for the treatment of:

  • Chronic severe drooling caused by neurologic disorders in children aged 3 to 16 years.

Unlike Robinul, which may be used off-label for a variety of conditions such as hyperhidrosis (excessive sweating), peptic ulcers, and IBS among others, Cuvposa's use is more focused on pediatric patients with specific needs.

How does Cuvposa help with these illnesses?

Cuvposa, similar to Robinul, works by blocking the action of acetylcholine, a neurotransmitter that stimulates the production of saliva and sweat. Acetylcholine plays roles in many processes in the body including muscle contractions, heart rate regulation and cognitive functions such as memory recall and attention. Cuvposa is specifically designed for pediatric patients with chronic severe drooling associated with neurologic conditions like cerebral palsy. Its primary function is to reduce salivary secretions thereby alleviating some unwanted symptoms related to excessive drooling. Like Robinul, it inhibits the muscarinic action of acetylcholine on smooth muscles but has been formulated in an oral solution making it easier for children administration compared to tablets or injectables which are typical forms available for Robinul. Hence Cuvposa may be prescribed when a patient requires long term treatment for chronic conditions or when other treatments like Botox injections haven't worked sufficiently.

How effective are both Robinul and Cuvposa?

Both glycopyrrolate (Robinul) and Cuvposa have well-documented histories of success in managing excessive drooling, especially among pediatric patients with neurological disorders. Robinul was first approved by the FDA in 1961 for peptic ulcer disease, while Cuvposa received its approval specifically for chronic severe drooling caused by neurologic conditions in children ages 3 to 16 years old later on.

They work through the same mechanism - being anticholinergic medications that reduce saliva production – and may be prescribed depending on individual circumstances. A direct comparison study conducted between Robinul and Cuvposa has not yet been performed; however, both drugs are known to exhibit similar efficacy in managing symptoms related to overactive salivary glands as well as safety profiles.

A review published in Pediatric Neurology highlighted that glycopyrrolate is effective at reducing problematic drooling within a week of starting treatment, demonstrating a favorable side effect profile compared to other alternative treatments. It is also well-tolerated among different age groups including children above three years old.

A separate clinical trial indicated that Cuvposa seems to be more effective than placebo at reducing sialorrhea or excessive salivation symptoms based upon objective measurements such as saliva weight. However, data confirming its efficacy as stand-alone therapy for this condition is less robust than it is for glycopyrrolate which also exhibits widespread use beyond treating hyperhidrosis and chronic severe drooling.

At what dose is Robinul typically prescribed?

Oral dosages of Robinul range from 1-15 mg/day, depending on the condition being treated. However, studies have shown that a starting dose of 2 mg three times daily is generally effective for excessive sweating and other conditions in most adults. For children with hyperhidrosis or excessive drooling, Cuvposa can be started at a dosage of .02mg/kg three times daily. In both populations, if there's no response after several weeks, the dosage may be increased gradually under medical supervision. It's important to note that nobody should exceed a total daily dose of 6mg for Cuvposa and 8 mg for Robinul.

At what dose is Cuvposa typically prescribed?

Cuvposa treatment typically begins with a dosage of 1 mg orally, three times daily. The dose can then be increased to 2 mg per day, divided into three doses, spaced about 8 hours apart. If there is no significant response after two weeks of treatment at this level, the maximum dose may be tested which goes up to 3 mg/day divided into three equal doses and spaced approximately eight hours apart. It should be stressed that Cuvposa dosage adjustments should always occur under the supervision of your healthcare provider over several weeks or months in order to find the most effective and tolerable regimen for each individual patient.

Common side effects of Robinul and Cuvposa may include:

  • Dry mouth
  • Decreased sweating
  • Constipation
  • Dizziness, drowsiness, or weakness
  • Blurred vision or dilated pupils
  • Nervousness or confusion
  • Difficulty urinating
  • Increased sensitivity to light

  • Vision problems: Using this medication could result in blurred vision or eye pain. If you experience these symptoms while taking Cuvposa, seek immediate medical attention.
  • Heat intolerance and fever due to decreased sweating. This is a serious effect that needs immediate medical intervention.

If you notice any of these effects while taking Cuvposa, stop using the drug and contact your doctor immediately.

Contraindications for Robinul and Cuvposa?

Both Robinul and Cuvposa, as with most other anticholinergic medications, may worsen symptoms of certain conditions in some people. If you notice your dry mouth or eyes worsening, an increase in blurred vision, constipation or difficulty urinating while taking these drugs, please seek immediate medical attention.

Neither Robinul nor Cuvposa can be taken if you are already using potassium tablets or have been diagnosed with glaucoma, myasthenia gravis, kidney disease or an enlarged prostate. Always disclose to your physician which medications you are taking; certain medicines like amantadine and quinidine will require careful monitoring due to their potential interactions with Robinul and Cuvposa.

How much do Robinul and Cuvposa cost?

For the brand name versions of these drugs:

  • The price of 100 tablets of Robinul (1 mg) averages around $400, which works out to $4–$12/day, depending on your dose.
  • The price of a bottle containing 473ml of Cuvposa (1mg/ml) is approximately $2,500. A typical dosage might be between 3 and 6 ml per day, working out to anywhere from about $15.90 to nearly $32/day.

Thus, if you are in the higher dosage range for Robinul (i.e., 3 mg/day or higher), then brand-name Cuvposa can become more costly on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.

On the other hand, generic versions of these medications offer significant savings:

  • Glycopyrrolate (the generic version of Robinul) costs around $.50–$4.00 per tablet depending upon strength and quantity purchased.
  • There isn't currently an FDA-approved equivalent available as a liquid form like Cuvposa; however glycopyrrolate does come in cheaper pill form as mentioned above or even less expensive injectable forms although administration would differ greatly from the oral solutions provided by both branded products listed here.

As always consult with your healthcare provider regarding any medication changes or decisions based on individual health circumstances and needs.

Popularity of Robinul and Cuvposa

Glycopyrrolate, commonly known by brand names like Robinul and Cuvposa, is a medication primarily used to reduce bodily secretions.

In 2020, it was estimated that around 500,000 prescriptions of glycopyrrolate in the form of Robinul have been filled in the U.S., accounting for about 1% of all anticholinergic prescriptions. This prescription rate has remained steady over the past decade due to its consistent efficacy and tolerability.

On the other hand, Cuvposa's prevalence has seen an increase since its approval by FDA for pediatric chronic severe drooling associated with neurologic conditions such as cerebral palsy. About 50 thousand people were prescribed this specific brand version in 2020; however, it still accounts for less than one percent of overall glycopyrrolate prescriptions but shows potential growth due to its targeted use.


Both Robinul (glycopyrrolate) and Cuvposa (also glycopyrrolate, but a different formulation) are well-established in their use for managing symptoms of certain medical conditions. They function by blocking the action of acetylcholine on smooth muscles and other tissues, which can reduce the production of body fluids such as sweat or saliva.

In some cases, these two drugs may be used interchangeably, but this should always be under the careful supervision of a healthcare provider due to differences in indication and dosage form. Robinul is primarily prescribed for peptic ulcer disease or to reduce salivation during surgery whereas Cuvposa is specifically approved for chronic severe drooling caused by neurologic disorders in children.

While both medications are available generically as glycopyrrolate hence offering potential cost savings, they do differ slightly with regards to administration: Robinul comes in tablet form while Cuvposa is an oral solution which might facilitate its use especially among pediatric patients who struggle swallowing tablets.

Concerning side effects profile, both medications share similar ones including dry mouth, urinary retention and blurred vision; however tolerance varies from patient to patient. It's also important that those taking either drug monitor their responses closely since excessive usage could lead to more serious complications such as tachycardia or heat prostration.
