What are pergolide tablets?

PERGOLIDE (Permax®) can help treat Parkinson's disease. Pergolide helps to improve muscle control and movement difficulties. Pergolide will not cure Parkinson's disease, but will help to control the symptoms of the disease. Pergolide tablets are taken together with other tablets that control parkinsonian symptoms. Generic pergolide tablets are available.

NOTE: This drug is being removed from the US market. If you are currently taking Pergolide, contact your doctor about stopping this medicine and finding an alternative therapy. Do not stop taking this medicine without first speaking to your doctor. Abruptly stopping this medicine can be dangerous. You must gradually reduce the dose or you may get severe side effects.

What should I tell my health care provider before I take this medicine?

They need to know if you have any of these conditions:
• dizzy or fainting spells
• history of heart disease or heart valve disease
• low blood pressure
• an unusual or allergic reaction to pergolide, ergot alkaloids (like ergonovine or ergotamine), other medicines, foods, dyes, or preservatives
• pregnant or trying to get pregnant
• breast-feeding

How should I take this medicine?

Take pergolide tablets by mouth. Follow the directions on the prescription label. Swallow the tablets with a drink of water. Take your doses at regular intervals. Do not take your medicine more often than directed.

Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.

What drug(s) may interact with pergolide?

metoclopramide
• medicines for mental problems and psychotic disturbances

Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking pergolide?

Visit your prescriber or health care professional for regular checks on your progress. It may be several weeks or months before you feel the full effect of pergolide. Continue to take your medicine on a regular schedule and do not stop taking except on your prescriber's advice.

You may get dizzy or have difficulty controlling your movements. Do not drive, use machinery, or do anything that needs mental alertness until you know how pergolide affects you. Pergolide may cause abrupt drowsiness or sleep. If you experience abrupt sleepiness without warning, do not drive or use machinery while taking pergolide, and do not perform other activities where falling asleep could result in an injury. If you experience sudden sleep without warning, contact your health care professional immediately. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can increase possible dizziness; avoid alcoholic drinks.

Pergolide may make your mouth dry. Chewing sugarless gum, sucking hard candy and drinking plenty of water may help. Visit your dentist regularly.

If you are going to have surgery, tell your prescriber or health care professional that you are taking pergolide.

Pergolide (Permax) is an ergoline-based dopamine receptor agonist used for the treatment of Parkinson's disease.

Parkinson's disease is associated with low levels of the neurotransmitter dopamine in the brain. Pergolide has some of the same effects as dopamine in the body.

Indications

Pergolide is also used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinson's disease, although it has also been used to treat discomfort or pain in the lower extremities that can only be relieved by moving the legs. Pergolide is often used in conjunction with other medicines in the treatment of Parkinson's disease. Since Pergolide can reduce prolactin levels, it is often used to treat hyperprolactinemia.

Furthermore, pergolide may also be used for veterinary purposes. It is commonly used for the treatment of pituitary pars intermedia hyperplasia or Equine Cushing's Syndrome (ECS) in horses.[1]

Side Effects

The drug is in decreasing use, as it was reported in 2003 to be associated with a form of heart disease called cardiac fibrosis.[2] This problem is thought to be due to pergolide's action at the 5-HT2B serotonin receptors of cardiac myocytes, causing proliferative valve disease by the same mechanism as ergotamine, methysergide, fenfluramine, and other serotonin 5-HT2B agonists, including serotonin itself when elevated in the blood in carcinoid syndrome. Pergolide can rarely cause Raynaud's phenomenon. Among similar antiparkinsonian drugs, cabergoline but not lisuride exhibit this same type of serotonin receptor binding.[3] In January, 2007, cabergoline (Dostinex) was reported also to be associated with valvular proliferation heart damage.[4] In March 2007, pergolide was withdrawn from the U.S. market due to serious valvular damage that was shown in two independent studies.[5]

Pergolide has also been shown to impair associative learning.[6]

At least one British Pergolide user has attracted some media attention with claims that it has caused him to develop a gambling addiction.[7][8] On March 30, 2007, manufacturers of Pergolide agreed to withdraw the drug from the U.S. market after several published studies revealed a link between the drug and increased rates of valvular dysfunction.[9] However, Pergolide is still available in many other countries.
