Issues for surgery
For treatment of hypertension – loss of blood pressure (BP) control if omitted.
Risk of hypotension when continued.
Advice in the perioperative period
Elective and emergency surgery
Continue – monitor BP.
Post-operative advice
Restart post-operatively when next dose is due.
Monitor BP.
Interactions with common anaesthetic agents
Inhalational Anaesthetics
See also Hypotension below.
Lercanidipine may reduce the minimum alveolar concentration (MAC) of inhalational anaesthetics by up to 20%.
Hypotension
Lercanidipine can increase the risk of hypotension when used concomitantly with remifentanil or inhalational/intravenous anaesthetics.
Neuromuscular blocking drugs (NMBDs)
Lercanidipine may prolong neuromuscular blockade when used concomitantly with NMBDs. The clinical significance is unknown, but bear the potential interaction in mind in case of unexpected response to treatment.
Dantrolene
There is a potential interaction between intravenous dantrolene and calcium-channel blockers leading to acute hyperkalaemia and cardiovascular collapse. This interaction has occurred in animal studies with some calcium-channel blockers (CCBs). It is recommended that co-administration of lercanidipine with dantrolene should be avoided.
Interactions with other common medicines used in the perioperative period
Hypotension
Lercanidipine can increase the risk of hypotension when used concomitantly with droperidol or prochlorperazine.
Macrolide antibiotics
Macrolide antibiotics (e.g. clarithromycin, erythromycin), which are inhibitors of CYP3A4, may increase the effects of lercanidipine leading to hypotension. Monitor the patient and consider reducing the dose of the lercanidipine if necessary.
Whilst single surgical prophylactic doses should not pose a problem, continued post-operative treatment may require close monitoring. Consult current product literature.
