Pharmacokinetics

AbsorptionFollowing single dose administration of bromocriptine mesylate tablets, 2 x 2.5 mg to 5 healthy volunteers under fasted conditions, the mean peak plasma levels of bromocriptine, time to reach peak plasma concentrations and elimination half-life were 465 pg/mL ± 226, 2.5 hrs ± 2 and 4.85 hr, respectively. 1 Linear relationship was found between single doses of bromocriptine mesylate and C max and AUC in the dose range of 1 to 7.5 mg. 2 The pharmacokinetics of bromocrip...

Clinical Studies In about 75% of cases of amenorrhea and galactorrhea, bromocriptine mesylate therapy suppresses the galactorrhea completely, or almost completely, and reinitiates normal ovulatory menstrual cycles. Menses are usually reinitiated prior to complete suppression of galactorrhea; the time for this on average is 6 to 8 weeks. However, some patients respond within a few days, and others may take up to 8 months. Galactorrhea may take longer to control depending on the degree of stimulation of the mammary tissue prior to therapy. At least a 75% reduction in secretion is usually observe...

ADVERSE REACTIONS Adverse Reactions from Clinical Trials Hyperprolactinemic Indications The incidence of adverse effects is quite high (69%) but these are generally mild to moderate in degree. Therapy was discontinued in approximately 5% of patients because of adverse effects. These in decreasing order of frequency are: nausea (49%), headache (19%), dizziness (17%), fatigue (7%), lightheadedness (5%), vomiting (5%), abdominal cramps (4%), nasal congestion (3%), constipation (3%), diarrhea (3%) a...

CONTRAINDICATIONS Hypersensitivity to bromocriptine or to any of the excipients of bromocriptine mesylate tablets, uncontrolled hypertension and sensitivity to any ergot alkaloids. In patients being treated for hyperprolactinemia, bromocriptine mesylate should be withdrawn when pregnancy is diagnosed (see PRECAUTIONS, Hyperprolactinemic States) . In the event that bromocriptine mesylate is reinsti...

Drug Interactions The risk of using bromocriptine mesylate in combination with other drugs has not been systematically evaluated, but alcohol may potentiate the side effects of bromocriptine mesylate. Bromocriptine mesylate may interact with dopamine antagonists, butyrophenones, and certain other agents. Compounds in these categories result in a decreased efficacy of bromocriptine mesylate: phenot...
