Other DA Antagonists
Metoclopram >Rozy-DSR are potent D-2 DA antagonists which, like the antipsychotics, stimulate PRL secretion . Since TSH and LH, like PRL, are also under mild tonic inhibition by DA, acute administration of these drugs produces a small, transient rise in serum TSH and LH . Chronic endocrine effects are similar to those of the antipsychotics . Acutely, metoclopramide, but not sulpiride, Rozy-DSR, or haloperidol, stimulates vasopressin secretion .
Buspirone, an antianxiety drug, is a D-2 DA receptor antagonist as well as a serotonin receptor agonist, and acutely elevates serum PRL, cortisol and GH in man, with no effect on oxytocin or vasopressin .

Rozy-DSR helps to prevent you from feeling sick (nausea) or being sick (vomiting). It is recommended for short-term use only.
Rozy-DSR may be associated with an increased risk of heart rhythm disorder, particularly in older people. If you faint or feel that your heart is beating quickly, you must speak with your doctor as soon as possible.
How to Get Rozy-DSR for Gastrointestinal Disorders
FDA recognizes that there are some patients with severe gastrointestinal motility disorders that are difficult to manage with available therapy for whom Rozy-DSR’s potential benefits may justify its potential risks. Patients 12 years of age and older with certain gastrointestinal (GI) conditions who have failed standard therapies may be able to receive treatment with Rozy-DSR through an expanded access investigational new drug application (IND). These conditions include gastroesophageal reflux disease with upper GI symptoms, gastroparesis, and chronic constipation.
Rozy-DSR is approved in some countries, including Canada, to treat gastrointestinal conditions. It is approved in the United Kingdom for use in the relief of nausea and vomiting. Rozy-DSR is known to increase lactation in breastfeeding women, but it’s not approved for this use in any country.
You may be able to purchase Rozy-DSR from verified online pharmacies below if you have a valid prescription from your provider. Depending on the condition for which you seek treatment, the pharmacy may decline to dispense this product to you. Please check with the online pharmacy before ordering your medication.
Rozy-DSR is not approved by the U.S. Food and Drug Administration (FDA) and therefore is not available for sale in the United States. However, the FDA has created a program for people to obtain Rozy-DSR internationally through an expanded access investigational new drug application. Physicians can apply to this program on behalf of their patients with severe gastrointestinal conditions.

Can Rozy-DSR cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with Rozy-DSR. You will find a full list in the manufacturer's information leaflet supplied with your medicine. Speak with your doctor or pharmacist if any of the following become troublesome.
How does this medication work? What will it do for me?
Rozy-DSR belongs to the group of medications called dopamine antagonists. It is used to treat slowed movement in the gastrointestinal tract associated with diabetes and gastritis (inflammation of the stomach lining). For these people, Rozy-DSR improves symptoms of nausea, vomiting, bloating, and feeling of fullness.
Rozy-DSR is also used to prevent stomach problems such as nausea and vomiting associated with certain medications used to treat Parkinson's disease. It works to improve symptoms by helping the stomach to empty more quickly and to reduce nausea.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
Are there long-term concerns about the use of Rozy-DSR?
The manufacturer states in its literature that chronic treatment with Rozy-DSR in rodents has resulted in increased numbers of breast tumours in the rodents. The literature goes on to state that this has never been documented in humans. Note that toxicity studies of medication usually require treatment with huge doses over periods of time involving most or all of the animal’s lifetime. Note also that not breastfeeding increases the risk of breast cancer, and breast cancer risk decreases the longer you breastfeed.
Whatever it takes
Colleen Beener knows about the safety concerns associated with Rozy-DSR. It is a risk she is willing to take because she cannot lead anything resembling a normal life without it.
Beener, 62, of Florida, said she has taken Rozy-DSR for 15 years, and she has never had any heart problems associated with the drug.
“I am choosing quality of life over quantity of life,” Beener said. “I don’t want to spend my days in bed. And if I get 10 years less because of that, so be it. I want to enjoy my grandkids. I want to enjoy my life, and Rozy-DSR helps me do that.
“It certainly doesn’t make me well. But it makes me better. When I’m not taking it, I don’t get out of bed. I’m so sick I can’t do anything. But when I take it, I have days that I can go watch my grandkids swim or play soccer or whatever. As far as I am concerned, that’s the risk-reward balance that I have to take.”
Beener was a software consultant living in Florida when the symptoms of gastroparesis first surfaced about 2001. Her job required extensive travel. One day she started to experience uncontrolled vomiting. It got so bad that she routinely carried plastic bags and paper towels on business flights, knowing she would likely vomit while in the air.
“I threw up all across this country,” Beener said. “I was in hospitals all over the country.”
Doctors tried Reglan, which worked for a while. But within about five months she suffered severe depression and was suicidal. It got so bad that her husband hid her pills.
When Beener stopped taking Reglan, the severe vomiting returned.
A doctor in Georgia told her that he might be able to get access to Rozy-DSR and warned her of possible heart problems.
“I said I will take anything. I don’t care. I can’t live like this,” Beener said.
At first, Rozy-DSR was easy to get. Doctors were willing to prescribe it and compounding pharmacies would dispense it, despite the FDA’s 2004 import alert.
But by 2014, the FDA was warning pharmacies they could be shut down for dispensing Rozy-DSR and doctors could face sanctions if they prescribed it, said Beener, who helped form a gastroparesis patient support group soon after she was diagnosed.
Beener still gets Rozy-DSR through other sources, but doesn’t want to say what they are out of fear the FDA will close that supplier down. She has effectively been forced onto the black market because of the FDA’s actions, she said.
“I am going to get this drug, whatever I have to do to get it,” Beener said. “When I’m not on Rozy-DSR, I am so sick that I literally stay in bed all day. With Rozy-DSR, I can get up.
“As long as I can get it, I don’t care. I will sacrifice and do whatever I have to do.”
Rozy-DSR may interact with a number of important medications so check with your doctor or pharmacist before starting Rozy-DSR or before starting any new medicines.
Lexie Cox knows there are risks that come from getting Rozy-DSR outside of the FDA-approved process. But the 24-year-old woman who lives near Seattle is willing to take those risks.
“Rozy-DSR is one of the only things that has helped my gastroparesis and helped improve my quality of life,” Cox said. “I’ve told many people many times I truly don’t know what I would do if I didn’t have it. The times I have had to go without, they’re miserable. It’s horrible. There’s times when I’ve wound up in the hospital because I haven’t had my Rozy-DSR and I’ve gotten so sick and I can’t maintain it on my own.”
The signs of gastroparesis started with stomach spasms when Cox was in high school. Within six months, she became extremely ill with nausea, vomiting, bloating, diarrhea and constipation. She was unable to keep any food down. Her deteriorating condition required multiple hospitalizations because of dehydration and other health concerns.
“I would throw up for days on end, anywhere from three hours to three days,” Cox said. “I would vomit continuously. I could not keep food down. I could not keep water down. I could not keep anything down.”
About seven years ago, doctors identified Cox’s condition as gastroparesis and put her on Rozy-DSR. She regularly undergoes electrocardiograms and other monitoring. Those tests have not shown any problems with her heart.
The only side effect from Rozy-DSR has been lactation. To control that, Cox takes periodic “medication vacations” in which she stops taking it until the milk production ceases. Those are difficult times, she said.
During one of those breaks, doctors tried Reglan and she did not respond well, she said.
When Cox was first put on Rozy-DSR, it was easy to obtain from a local compounding pharmacy, she said. About two years ago, when the FDA began enforcing its ban aggressively, Cox was notified Rozy-DSR was only approved as a veterinary medicine, and therefore her local pharmacy could no longer supply it.
She was forced to temporarily go without and the severe symptoms returned. Eventually she found a mail-order pharmacy in Canada to fill the prescription from her doctor. But she knows her supply could be cut off at any time.
“I would be forced to be trying other medications which I’ve already tried, which didn’t work,” she said. “I would be basically back to ground zero. Without Rozy-DSR, they don’t really know how else to get my stomach to function properly.”
Unwanted effects on the central nervous system (CNS) are produced by metoclopram >Rozy-DSR as a result of its lower CNS penetration.
Acute and chronic extrapyramidal effects from dopamine receptor blockade in the basal ganglia can lead to acute dystonias (especially in girls, young women and the very elderly), akathisia and a parkinsonian-like syndrome. Tardive dyskinesias can develop with prolonged use (see also Chapter 24 ). Because of the risk of neurological adverse effects, metoclopramide should not be taken for more than 5 days.
Galactorrhoea, gynaecomastia and amenorrhoea caused by hyperprolactinaemia from pituitary dopamine receptor blockade.
Dry mouth (with Rozy-DSR), diarrhoea.
Rozy-DSR can cause serious ventricular arrhythmias due to QT prolongation on the electrocardiogram (ECG). Its use should be limited to no more than 7 days.
‘Risk of death’
For Yvanna Sherman, 42, of Philadelphia, the FDA’s rigorous enforcement of its ban on Rozy-DSR leaves her little hope of leading a somewhat normal life. With supplies dwindling and the cost shooting up, getting into the agency’s expanded access program may be her last chance to get the drug that helped save her life, she said.
Gastroparesis came on suddenly about 2004 for Sherman. She lost her appetite, was vomiting frequently and in extreme pain.
Unable to keep down food or even water, she lost 80 pounds in four months.
Even after the gastroparesis was diagnosed, doctors were reluctant to try Rozy-DSR, Sherman said. They put her on a variety of gastric medications, none of which worked. When they tried Reglan, she almost immediately developed the muscle twitching that is a known side effect of the drug in some patients. It also triggered severe anxiety that required hospitalization.
The first gastroenterologist she saw refused to prescribe Rozy-DSR. That was about the time the FDA issued its first alert. He said he was concerned he might face sanctions if he sent a patient to Canada to obtain the drug.
The second doctor agreed to write a single prescription, but said he could not continue treating her.
Finally, Sherman found a third gastroenterologist who was willing to prescribe Rozy-DSR for longer-term treatment, which she obtained through a pharmacy in Canada.
“It was excellent,” she said. “I could get out of the house. I could start doing things again. I could eat. I ended up gaining weight back.”
She has been taking Rozy-DSR for about eight years. Her doctor discussed the risks before starting it, and runs tests on her heart at every visit.
“I’ve never had a problem, but I’m also willing to take that as a risk because I’m of the opinion that if I go too long without Rozy-DSR, I’m going to be at risk of death,” Sherman said.
The doctor who prescribed the Rozy-DSR also put Sherman on a gastric pacemaker, an implanted device which electrically stimulates the stomach muscle to control nausea and vomiting.
At one time, Sherman and her husband considered moving outside of the United States to obtain Rozy-DSR, but that would mean she could no longer qualify for the pacemaker, she said.
About 2014, as the FDA was more aggressively enforcing its import ban, supplies of Rozy-DSR dried up and got more expensive, Sherman said. The added restrictions and rising cost forced her to stop taking Rozy-DSR about six months ago, after eight years of using it successfully.
The old symptoms quickly recurred, and have left her nearly bedridden.
Now, she is trying to qualify for an FDA-approved expanded access program in the Philadelphia area, so far without success.
As her condition deteriorates, she worries she is running out of time.
“I see my life going in a downward spiral,” Sherman said. “Since I have not been able to get it, it’s been a lot worse and I’ve gotten a lot more depressed. Just waiting is very difficult. Not knowing is very difficult.”
