Action ⬆ ⬇

Activates dopamine receptors in the CNS.
Decreases prolactin secretion.
Reduces fasting and postprandial blood glucose concentrations by increasing insulin sensitivity.

Relief of rigidity and tremor in parkinsonism.
Restoration of fertility in hyperprolactinemia.
Reduction in tumor size.

Classifications ⬆ ⬇

Therapeutic Classification: antiparkinson agents, antidiabetics

Pharmacologic Classification: dopamine agonists

Pharmacokinetics ⬆ ⬇

Absorption: Parlodel is poorly absorbed (30%) from the GI tract; 65–95% of Cycloset dose is absorbed (undergoes extensive first-pass metabolism; only 7% of dose reaches systemic circulation).

Distribution: 90–96% protein bound.

Metabolism/Excretion: Completely metabolized by the liver (metabolized by CYP3A4); primarily excreted in bile (2–6% excreted unchanged in urine).

Half-life: Biphasic—initial phase 4–4.5 hr, terminal phase 8–20 hr.

Patient/Family Teaching ⬆ ⬇

Instruct patient to take medication as directed. Take missed doses within 4 hr of the scheduled dose or omit. Do not double doses. Caution patient to avoid abrupt discontinuation to prevent withdrawal syndrome (apathy, anxiety, depression, fatigue, insomnia, sweating, pain). Advise patient to read the Patient Package Insert before taking and with each Rx refill, in case of changes.
- May cause drowsiness and dizziness. Caution patients to avoid driving and other activities requiring alertness until response to medication is known.
- Caution patient to change positions slowly to minimize orthostatic hypotension. Health care professional should be notified if orthostatic hypotension occurs.
- Caution patient to avoid concurrent use of alcohol during the course of therapy.
- Instruct patient to inform health care professional immediately if signs of MI (severe chest pain, fainting, fast heartbeat, increased sweating, continuing or severe nausea and vomiting, nervousness, shortness of breath, weakness) or increasing shortness of breath is noted; pulmonary infiltrates and pleural effusions may occur with long-term therapy.
- Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult health care professional before taking any Rx, OTC, or herbal products.
- Advise patient to notify health care professional if new or increased gambling, sexual, binge eating or other intense urges occur.
- Rep: Advise females of reproductive potential to notify health care professional if pregnancy is planned or suspected and to avoid breastfeeding during therapy. Advise women to consult with health care professional regarding a nonhormonal method of birth control. If bromocriptine is used during pregnancy, notify health care professional if signs and symptoms of high blood pressure, heart attack, seizures, stroke or psychosis (losing touch with reality) occur during postpartum period. If bromocriptine is used for infertility, since pregnancy may occur prior to reinitiation of menses, advise patient to take a pregnancy test at least every 4 wk during amenorrheic period, and, once menses are reinitiated, every time a menstrual period is missed. Discontinue therapy as soon as pregnancy has been established.
- Emphasize the importance of regular follow-up examinations to determine effectiveness and monitor side effects.
Infertility: Instruct women treated for infertility to obtain daily basal body temperatures to determine when ovulation occurs.
Pituitary Tumors: Instruct patients taking bromocriptine for pituitary tumors to inform health care professional immediately if signs of tumor enlargement (blurred vision, sudden headache, severe nausea, and vomiting) occur.
Type 2 Diabetes: Explain to patient that this medication controls hyperglycemia but does not cure diabetes. Therapy is long term.
- Review signs of hypoglycemia and hyperglycemia with patient. If hypoglycemia occurs, advise patient to drink a glass of orange juice or ingest 2–3 tsp of sugar, honey, or corn syrup dissolved in water or an appropriate number of glucose tablets and notify health care professional.
- Encourage patient to follow prescribed diet, medication, and exercise regimen to prevent hypoglycemic or hyperglycemic episodes.
- Instruct patient in proper testing of serum glucose and ketones. These tests should be closely monitored during periods of stress or illness and health care professional notified if significant changes occur.
- Advise patient to carry a form of sugar (sugar packets, candy) and identification describing disease process and medication regimen at all times.
