Published Studies Related to Pyridostigmine

Efficacy of 3,4-diaminopyridine and pyridostigmine in the treatment of Lambert-Eaton myasthenic syndrome: a randomized, double-blind, placebo-controlled, crossover study. [2009.07]
3,4-Diaminopyridine and pyridostigmine are widely used to treat Lambert-Eaton myasthenic syndrome (LEMS), either alone or in combination... Therefore, we performed a placebo-controlled, double-dummy, double-blind, randomized, crossover study in nine patients with LEMS.

The effect of oral buspirone, pyridostigmine, and bethanechol on esophageal function evaluated with combined multichannel esophageal impedance-manometry in healthy volunteers. [2009.03]
BACKGROUND: There is limited information on medications with promotility effects on the esophagus. Studies in healthy volunteers have shown the potential role of the direct cholinergic agonist bethanechol and the serotonin receptor agonist buspirone in improving esophageal motility. It has been also shown that an acetylcholinesterase inhibitor, the short-acting drug edrophonium administered intravenously caused a greater increase in the esophageal contraction amplitude and duration than bethanechol. Edrophonium cannot be used as a promotility therapy owing to short duration of action and lack of oral administration. The use of another acetylcholinesterase inhibitor pyridostygmine with longer duration of action has not been studied. The aim of the study was to evaluate the effect of oral pyridostygmine (60 mg), buspirone (20 mg), and bethanechol (25 mg) on esophageal function assessed by combined multichannel intraluminal impedance-esophageal manometry... CONCLUSIONS: Oral pyridostygmine, buspirone, and bethanechol enhance esophageal motility with pyridostygmine appearing to have the greatest effect. A potential effect on improving esophageal function and symptoms in patients requires further study.

A six-month randomized controlled trial of exercise and pyridostigmine in the treatment of fibromyalgia. [2008.02]
OBJECTIVE: A subset of fibromyalgia (FM) patients have a dysfunctional hypothalamic-pituitary-insulin-like growth factor 1 (IGF-1) axis, as evidenced by low serum levels of IGF-1 and a reduced growth hormone (GH) response to physiologic stimuli. There is evidence that pyridostigmine (PYD) improves the acute response of GH to exercise in FM patients. The purpose of this study was to evaluate the clinical effectiveness of 6 months of PYD and group exercise on FM symptoms... CONCLUSION: Neither the combination of PYD plus supervised exercise nor either treatment alone yielded improvement in most FM symptoms. However, PYD did improve anxiety and sleep, and exercise improved fatigue and fitness. We speculate that PYD may have improved vagal tone, thus benefiting sleep and anxiety; this notion warrants further study.

Pyridostigmine, diethyltoluamide, permethrin, and stress: a double-blind, randomized, placebo-controlled trial to assess safety. [2006.10]
CONCLUSION: Combined, correct use of pyridostigmine, diethyltoluamide, and permethrin is well tolerated and without evidence of short-term physical or neurocognitive impairment.

Pyridostigmine treatment trial in neurogenic orthostatic hypotension. [2006.04]
BACKGROUND: Midodrine hydrochloride is the only drug demonstrated in a placebo-controlled treatment trial to improve orthostatic hypotension (OH) but it significantly worsens supine hypertension. By enhancing ganglionic transmission, pyridostigmine bromide can potentially ameliorate OH without worsening supine hypertension. OBJECTIVE: To evaluate the efficacy of a single 60-mg dose of pyridostigmine bromide, alone or in combination with a subthreshold (2.5 mg) or suprathreshold (5 mg) dose of midodrine hydrochloride, compared with placebo... CONCLUSIONS: Pyridostigmine significantly improves standing BP in patients with OH without worsening supine hypertension. The greatest effect is on diastolic BP, suggesting that the improvement is due to increased total peripheral resistance.

Clinical Trials Related to Pyridostigmine

Pyridostigmine and Its Effects on Autonomic Modulation in Diabetic Patients [Recruiting]
The purpose of the study is to determine if pyridostigmine bromide improves heart rate variability of type 2 diabetes mellitus subjects with cardiovascular autonomic neuropathy.

Use of Pyridostigmine for Constipation in Diabetics [Recruiting]
Doctors at Mayo Clinic are doing this study to learn if pyridostigmine, a drug, affects the speed at which food travels through the stomach, intestines and colon, and if pyridostigmine improves constipation symptoms in patients with diabetes. Pyridostigmine has been approved by the Food and Drug Administration (FDA) for routine clinical use, however, its use as proposed in this study is considered investigational.

A Study of Pyridostigmine in Postural Tachycardia Syndrome [Recruiting]

Pilot Study of Pyridostigmine Upon Immune Activation in HIV-1 Patients Who Have an Inadequate Immune Response [Not yet recruiting]
The purpose of this study is to determine whether the addition of Pyridostigmine to Highly Active Antiretroviral Therapy (HAART) increases the number of CD4+ T-cells in discordant patients in which viral load diminishes, but T-cell levels remain low after the initiation of treatment.

Testing Mestinon and Exercise in Fibromyalgia [Active, not recruiting]
The purpose of this trial was to test the combined and independent effects of 6 months of exercise and Mestinon in people with fibromyalgia. Specifically, we wanted to determine if Mestinon helped people with fibromyalgia have an easier time exercising and if their symptoms improved by the end of the trial.
