PURPOSE Ripasudil is a novel Rho-associated protein kinase inhibitor that is used to treat ocular hypertension. However, the comparison of the intraocular pressure (IOP)-lowering effects between ripasudil alone and other ocular hypotensive drugs has not been studied thoroughly. The purpose of this study is to examine the ocular hypotensive effects of 0.4% ripasudil, 2% pilocarpine, 0.5% timolol...

Epilepsy is a common neurological disorder characterized by seizure and loss of neuronal cells by abnormal rhythmic firing of neurons in the brain. In the present study, we investigated the effect of treadmill exercise on gamma-aminobutyric acid (GABA)ergic neuronal loss in relation with neuronal activation using pilocarpine-induced epileptic rats. The rats were divided into four groups: contro...

There is controversy concerning the effect of pilocarpine in the reversal of radio-induced xerostomia; however, the tests are usually performed at the end of radiotherapy. The present study evaluated the radioprotective effects of pilocarpine when ingested during radiation treatment. Eleven patients (recently diagnosed with head and neck cancer who were not undergoing radiotherapy) were divided...

One of the major signs of severe organophosphate poisoning is seizures. Previous studies have shown that both muscarinic agonist- and organophosphate-induced seizures require activation of muscarinic acetylcholine receptors in the central nervous system. Seizures induced by the muscarinic agonist pilocarpine require the M1 receptor and are modulated by cannabinoid CB1 receptors. In this study, ...

PURPOSE To evaluate the comparative efficacy of latanoprost monotherapy versus combined carteolol and pilocarpine therapy in patients with newly diagnosed glaucoma. METHODS Masked randomized prospective trial. This study included 51 patients (64 eyes) with newly diagnosed glaucoma or ocular hypertension. The cases were randomly divided into two treatment groups for administration of latanopro...

Status epilepticus (SE) is one of the most serious manifestations of epilepsy. Systemic inflammation and damage of blood-brain barrier (BBB) are etiologic cofactors in the pathogenesis of pilocarpine SE while acute osmotic disruption of the BBB is sufficient to elicit seizures. Whether an inflammatory-vascular-BBB mechanism could apply to the lithium-pilocarpine model is unknown. LiCl facilitat...

Pilocarpine induces a profuse flow of saliva, and it may re-establish saliva production in cases of drug-induced oral dryness. The aim of the study (a sub-study to the previous trial investigating the pilocarpine fluid effects in individuals suffering from drug-induced dry mouth) was to search for saliva quality changes induced by the treatments. Sixty-five individuals were enrolled in a random...

The effect on accommodation of pilocarpine given intramuscularly was studied on two species of monkey (Cercopithecus aethiops and Macaca irus), six young individuals of each species. The results are given as dose-response curves; 0.2 mg. per kilogram of pilocarpine caused little change in refraction, generally less than 2 D., and 2.0 mg. per kilogravi caused a large change in refraction in both...

This work investigates pilocarpine trapped in a matrix diffusion-controlled drug delivery system using hydrophilic inserts of Poly(2-hydroxyethyl methacrylate) (pHEMA) to ensure an increased bioavailability of pilocarpine and prolong the length of time in which the medication remains in the eyes of the test subjects. The physical and chemical properties of pilocarpine were investigated to eluci...

Twelve patients with chronic simple glaucoma were treated for 1 week with Ocusert-40, and the effects on the pupil, intraocular pressure, and refraction were measured. A comparison was made with the effects of pilocarpine eyedrop therapy in 8 of these patients. Both forms of pilocarpine treatment gave satisfactory control of intraocular pressure and both constricted the pupil to a similar degre...
