Adult: For the management of symptoms: 30 mg bid. Alternatively, 10 mg tid. Treatment duration depends on the condition and patient response. Dosage and treatment recommendations may vary among individual products or between countries (refer to specific local product guidelines).
Administration
Nicergoline Should be taken on an empty stomach.
Contraindications
Recent MI, acute haemorrhage, orthostatic hypotension, severe bradycardia.
Special Precautions
Patient with mild bradycardia, gout, and hyperuricaemia. Renal impairment. Elderly. Pregnancy and lactation.
Adverse Reactions
Significant: CNS depression; reduced systolic or diastolic blood pressure; hyperuricaemia; fibrosis (e.g. pulmonary, cardiac, cardiac valvular, retroperitoneal); ergotism. Gastrointestinal disorders: Abdominal discomfort, diarrhoea, constipation, nausea. General disorders and administration site conditions: Feeling hot. Nervous system disorders: Dizziness, drowsiness, headache. Psychiatric disorders: Agitation, confusion, insomnia. Skin and subcutaneous tissue disorders: Pruritus, rash. Vascular disorders: Flushing.
Patient Counseling Information
This drug may cause dizziness or drowsiness, if affected, do not drive or operate machinery.
Monitoring Parameters
Monitor blood pressure periodically, particularly if given with other antihypertensive agents.
Overdosage
Symptom: Transient reduction in blood pressure, particularly with high doses.
Management: Symptomatic and supportive treatment. May administer sympathomimetics and perform continuous blood pressure monitoring in case of serious blood supply deficiency to the brain and heart.
Drug Interactions
May potentiate the effects of antihypertensive drugs. May potentiate the cardiac effects of β-blockers (e.g. propranolol). May antagonise the vasoconstrictor effect of sympathomimetic agents. May result in prolonged bleeding period with anticoagulants and aspirin.
Action
Description: Mechanism of Action: Nicergoline is a semisynthetic ergot derivative with α1-adrenergic blocking activity to produce vasodilation. It appears to exert additional properties that contribute to its effect on dementia or vascular disorders, such as increasing the cerebral blood circulation and consumption of glucose and oxygen and enhancing catecholaminergic neurotransmitter function. Nicergoline may also have an inhibitory effect on platelet aggregation. Pharmacokinetics: Absorption: Rapidly and well absorbed. Bioavailability: 5%. Time to peak plasma concentration: 1.5-3 hours (nicergoline); 3-5 hours (10 α-methoxy-9,10-dihydrolysergol [MDL]); 0.5-1 hour (1-methyl-10 α-methoxy-9,10-dihydrolysergol [MMDL]). Distribution: Volume of distribution: 224 L. Plasma protein binding: 34.7% (MDL); 14.7% (MMDL). Metabolism: Metabolised mainly via hydrolysis into MMDL (active metabolite), then via demethylation by CYP2D6 to form MDL (main active metabolite). Excretion: Via urine (82%); faeces (10%). Elimination half-life: 11-20 hours (MDL).
