BACKGROUND Pyridostigmine bromide (3-[[(dimethylamino)-carbonyl]oxy]-1-methylpyridinium bromide), a reversible inhibitor of cholinesterase, is given orally in tablet form, and a treatment schedule of multiple daily doses is recommended for adult patients. Nanotechnology was used in this study to develop an alternative sustained-release delivery system for pyridostigmine, a synthetic drug with h...

I read the recent publication by Leong et al on the effect of pyridostigmine or Mestinon on human platelet aggregation with a great interest. In medicine, pyridostigmine has been investigated for its effect on biochemical and hematological parameters. Indeed, such effects have already been studied in animal models. Somani et al reported on signifi cant change due to receipt of pyridostigmine in...

Mentally or emotionally stressful situations occur throughout our lives and cause physiological haemodynamic responses. In patients with coronary artery disease, such events can also induce myocardial ischaemia and ventricular arrhythmias, increasing mortality rates. The purpose of the present study was to determine the acute effects of the oral administration of pyridostigmine, a reversible ch...

Objective: To characterise the effects of acetylcholinesterase inhibition with pyridostigmine on parasympathetic tone in patients with chronic heart failure (CHF). Design: Prospective randomised, double blind crossover trial. Setting: University hospital outpatient heart failure clinic. Patients: 20 ambulatory subjects with stable CHF (mean age 55 years, mean ejection fraction 24%). Interventio...

OBJECTIVE To evaluate the long-term (for up to 3 months) efficacy and safety of single or combined therapy with midodrine and pyridostigmine for neurogenic orthostatic hypotension (OH). METHODS This was a randomized, open-label clinical trial. In total, 87 patients with symptomatic neurogenic OH were enrolled and randomized to receive 1 of 3 treatments: midodrine only, pyridostigmine only, or...

Pyridostigmine bromide, a reversible anticholinesterase drug, was used by military personnel during the Gulf War. They were under physical stress and might have been exposed to low-dose nerve gas, sarin. This study examined the interactions of low-dose sarin and pyridostigmine in exercised mice. Male NIH Swiss mice were treated as follows: 1) Control; 2) Sarin (0.01 mg/kg, sc); 3) exercise; 4) ...

Experiments tested the effect of stress coupled with cholinesterase inhibition on blood pressure, heart rate, baroreflex index, and variability in time and frequency domain in conscious mice. The objective was to determine whether cholinergic systems interact with stress to alter cardiovascular responses. Male C57BL/6J mice with arterial catheters were exposed to 3-day treatments: 1) intermitte...
