"Naropin® has the potential to become the drug of choice for spinal anaesthesia using various doses for different clinical situations," commented Kjell Ahlén, Global Medical Director for Anaesthesia. "It is anticipated that Naropin® for spinal anaesthesia will be welcomed as an effective and safe drug both in patients who receive operations on a day case basis as well as in patients who have to stay hospitalised following major surgery."
In clinical studies, Naropin® was shown to provide excellent spinal anaesthesia and muscular relaxation for orthopaedic, gynaecological or urological surgery and was well tolerated. A dose interval of 15-25 mg seems adequate to achieve good surgical anaesthesia. Naropin® has a favourable efficacy and safety profile.
Naropin® is currently approved for epidural anaesthesia during surgery and post-operative pain relief, pain relief in childbirth, Caesarean section, local infiltration anaesthesia, for surgery using peripheral nerve block techniques and for continuous peripheral nerve block for post operative pain relief.
The Netherlands acted as the Reference Member State in the Mutual Recognition procedure for European approval and Naropin® has already received approval for this new route of administration in Finland, New Zealand, Switzerland, Sweden, Iceland, Mexico, Argentina and Australia.

Notes to editor:
Spinal (= intrathecal or subarachnoid) block technique involves the injection of local anaesthetic into the cerebrospinal fluid at the lower part of the backbone, thereby temporarily stopping the nerve impulse transmission and the sensation of pain from a part of the body. For surgery, the 5.0 mg/ml concentration of Naropin® is selected so that muscle function is also anaesthetized, and thereby muscle relaxation is provided. Muscle relaxation is often required by the surgeon, especially during major orthopaedic surgery procedures. When general anaesthesia is used, muscle relaxation is instead achieved by addition of a neuromuscular blocking agent to the general anaesthetic agent.
