Issues for surgery
For Parkinson’s disease (PD) - risk of exacerbation of PD and akinesia if omitted.
For restless legs – loss of effect if omitted.
Risk of Dopamine Agonist Withdrawal Syndrome (DAWS) if omitted (see Further information).
Advice in the perioperative period
Elective and emergency surgery
Continue.
To minimise disruption to the patient’s usual medication regime pramipexole can be given with a sip of water up until anaesthetic induction.
If a long nil by mouth (NBM) period is anticipated post-operatively the patient’s specialist should be contacted pre-operatively for advice on alternative routes or medications.
Post-operative advice
Resume post-operatively at patient’s usual dose.
If a long NBM period is anticipated or if there are concerns regarding enteral absorption alternative routes / medications should be considered (see Further information).
Interactions with common anaesthetic agents
For general information regarding the use of anaesthetic agents in PD – see Parkinson’s Disease Overview.
Hypotension
Pramipexole can increase the risk of hypotension when used concomitantly with inhalational or intravenous anaesthetics.
Interactions with other common medicines used in the perioperative period
Antiemetics
Pramipexole can increase the risk of hypotension when used concomitantly with droperidol or prochlorperazine. However, these medications should be avoided in patients with PD as they exacerbate symptoms.
For general information regarding the use of antiemetics in PD – see Parkinson’s Disease Overview.
Further information
Dopamine Agonist Withdrawal Syndrome (DAWS)
Abrupt withdrawal or tapering of dopamine agonists is associated with DAWS, which mimics Neuroleptic Malignant Syndrome (NMS). Symptoms include apathy, anxiety, depression, nausea, fatigue, orthostatic hypotension, sweating and pain, which may be severe. Patients should be informed about this before tapering the dopamine agonist and monitored regularly thereafter. In case of persistent symptoms, it may be necessary to increase the dopamine agonist dose temporarily.
NBM period and alternative routes
If there is significant post-operative nausea and vomiting, post-operative ileus or concerns about enteral absorption, the oral route is likely to be unreliable and may lead to suboptimal treatment and potentially DAWS. Alternative routes or medications should be considered – see Parkinson’s Disease Overview.
Patients who do not rapidly regain the ability to take their usual PD medication should be seen by a PD specialist nurse or movement disorder consultant at the earliest opportunity.
If PD treatment is interrupted for more than one day or restless legs treatment is interrupted for more than a few days the manufacturer of ropinirole advises doses should be re-titrated.
Prescribing and administration
Access to the correct medication or formulation at the correct time remains a problem for people with PD whilst they are in hospital. Delayed doses can have serious implications. PD patients often have complex medication regimes; prescribers should take care to confirm the correct dose, formulation and time of administration with the patient or carer. The time of administration should be documented on the prescription chart and nursing staff should ensure that PD medications are given promptly.
