| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
| The study is looking at the cerebrospinal fluid pharmacokinetics of intravenous paracetamol. |
|
| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To evaluate the distribution of intravenous paracetamol within the body, in particular the penetration from blood into the fluid surrounding the spinal cord. |
|
| E.2.2 | Secondary objectives of the trial |
To measure the effect of intravenous paracetamol on prostaglandins (mediators involved in inflammation in the body). To measure the concentration of AM404 (a metabolite of paracetamol which prevents the reuptake of cannabinoids). This may provide more information on the mechanism of action of paracetamol. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
Adult patients aged 18 and 80 years from whom full written informed consent will be sought. Patients undergoing surgery who require a spinal anaesthetic and paracetamol as part of their routine anaesthetic Patients who fall into the American Society of Anesthesiologists scoring system of ASA I−III. Patients with no known clotting abnormalities Patients who have given written informed consent
|
|
| E.4 | Principal exclusion criteria |
Patients with any contraindication to spinal anaesthesia Patients with known clotting abnormalities. Pregnant women. Patients who have known hypersensitivity to paracetamol. Any patients who are deemed unsuitable by the investigators due to medical reasons. Subjects who have received an investigational drug or have used an investigational device in the 30 days preceding to study entry.

| E.5 End points |
| E.5.1 | Primary end point(s) |
| The cerebrospinal levels of paracetamol post administration of intravenous paracetamol |
