About

Anticholium® per Se is a randomized, double-blind, placebo-controlled, monocentric trial to assess whether the CAP can be transferred from bench to bedside. In this pilot study, 20 patients with perioperative sepsis and septic shock as a result of intra-abdominal infection are enrolled. According to randomization, participants are treated with physostigmine salicylate (verum group) or 0.9% sodium chloride (placebo group) for up to 5 days. The mean Sequential Organ Failure Assessment (SOFA) score during treatment and subsequent intensive care of up to 14 days is used as surrogate outcome (primary endpoint). Secondary outcome measures include 30- and 90-day mortality. An embedded pharmacokinetics and pharmacodynamics study investigates plasma concentrations of physostigmine and its metabolite eseroline. Further analyses will contribute to the understanding of the role of various cytokines in the pathophysiology of human sepsis. A computer-generated list is used for blocked randomization.

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Quadruple Blind

---

20 participants in 2 patient groups, including a placebo group

Treatment Group

Active Comparator group

Description:

The treatment group receives an infusion of 0.04 mg/kg physostigmine salicylate with a maximum dose of 4 mg. The infusion is administered at 0.4 mg/min (= 1 mL/min = 60 mL/h). The initial dose is followed by a continuous infusion of 0.017 mg/min, i.e. 1 mg/h (= 0.042 mL/min = 2.5 mL/h) for 2-5 days, i.e. 48-120 hours (treatment phase).

Treatment:

Drug: Physostigmine

Placebo Group

Placebo Comparator group

Description:

The placebo group is treated with 0.9% sodium chloride.

Treatment:

Drug: Isotonic Saline
