Previous experiments have shown that the generation of free radicals in rat brain homogenates is increased following pilocarpine-induced seizures and status epilepticus (SE). This study was aimed at investigating the changes in neurochemical mechanisms such as lipid peroxidation levels, nitrite content, glutathione reduced (GSH) concentration, superoxide dismutase and catalase activities in the...

Thirty eyes of 15 patients with open-angle glaucoma were followed up for a period of up to 1 year while being treated with Piloplex eye drops containg a new long-acting pilocarpine polymer salt. Average morning intraocular pressure (IOP) values during treatment with pilocarpine hydrochloride administered 4 times daily was 20.5 mmHg. Average morning IOP values during Piloplex medication adminis...

Cevimeline and pilocarpine are muscarinic agonists used clinically to treat dry mouth. In this study, we explored fluid secretion from mouse submandibular glands to determine the mechanism of cevimeline, pilocarpine, and an experimentally used agent carbachol. Cevimeline evoked almost the same amount of secretion at concentrations from 30 μM to 1 mM. Pilocarpine also induced secretion at a conc...

BACKGROUND Patients with radiation-induced xerostomia produce little or no saliva. Several studies have demonstrated the efficacy of systemic administration of pilocarpine hydrochloride in individuals with post-radiation xerostomia. However, analysis of pilocarpine lozenges for treatment of post-radiation xerostomia in patients with head and neck cancer has not been reported. METHODS The aim ...

This article examines the use of pilocarpine hydrochloride for radiation-induced xerostomia in patients with head and neck cancer. Four randomized controlled trials involving 401 patients met the authors' predefined inclusion criteria and were critically appraised. Three studies used topical pilocarpine as a mouthwash. Outcome measurements were both quantitative and qualitative. The studies rep...

I treated cynomolgus monkeys with topical echothiophate iodide twice daily for several months. Accommodative responses to topical or intramuscular pilocarpine were determined after ciliary ganglion or cholinergic nerve blockade. During echothiophate treatment, there was little or no accommodative response to intramuscular pilocarpine doses which were near maximal in nonechothiophate-treated eye...

The Ocusert-pilocarpine devides with seven days' therapeutic duration were compared with pilocarpine eye drops for efficacy and ocular tolerance in the management of glaucoma in 16 patients. Magnitude of pressure reduction with release rates of 20 mcg. and 40 mcg. of pilocarpine per hour were as effective in the treatment of glaucoma as 2 per cent and 4 per cent pilocarpine eye drops, respectiv...

Clinical and experimental evidence indicates that the amygdala is involved in limbic seizures observed in patients with temporal lobe epilepsy. Here, we used simultaneous field and intracellular recordings from horizontal brain slices obtained from pilocarpine-treated rats and age-matched nonepileptic controls (NECs) to shed light on the electrophysiological changes that occur within the latera...

Status epilepticus is the most common serious neurological condition triggered by abnormal electrical activity, leading to severe and widespread cell loss in the brain. Lithium has been one of the main drugs used for the treatment of bipolar disorder for decades, and its anticonvulsant and neuroprotective properties have been described in several neurological disease models. However, the therap...

Understanding the pathophysiogenesis of temporal lobe epilepsy (TLE) largely rests on the use of models of status epilepticus (SE), as in the case of the pilocarpine model. The main features of TLE are: (i) epileptic foci in the limbic system; (ii) an "initial precipitating injury"; (iii) the so-called "latent period"; and (iv) the presence of hippocampal sclerosis leading to reorganization of ...
