Pilocarpine HCl (Pilocarpal; NSC-5746; Ocusert; Pilocar;Pilocar SMP; Salagen; NSC5746), the hydrochloride salt of pilocarpine, is a naturally occurring and nonselective muscarinic acetylcholine receptor agonist used to treat dry mouth caused by radiotherapy in patients with head and neck cancer and in patients with Sjogren's syndrome. It is also used to produce an experimental model of epilepsy. Pilocarpine is a parasympathomimetic alkaloid extracted from the leaves of tropical American shrubs from the genus Pilocarpus. Pilocarpine acts on a subtype of muscarinic receptor (M3) found on the iris sphincter muscle, causing the muscle to contract and engage in miosis.
| ln Vitro |
The morphology and viability of human corneal stromal (HCS) cells are assessed using light microscopy and the MTT assay, respectively, in order to assess the cytotoxicity of pilocarpine. HCS cells exposed to Pilocarpine at concentrations between 0.625 and 20 g/L exhibit morphological abnormalities such as cellular shrinkage, cytoplasmic vacuolation, detachment from the culture matrix, and eventually death, as well as dose- and time-dependent proliferation retardation, according to morphological observations. However, there is no discernible difference between the controls and those exposed to Pilocarpine below the concentration of 0.625 g/L. The MTT assay results show that after being exposed to pilocarpine above a concentration of 0.625 g/L, the cell viability of HCS cells decreases with time and concentration (P<0.01 or 0.05), but HCS cells treated with pilocarpine below a concentration of 0.625 g/L do not significantly differ from controls[2]. With an EC50 of 2.4 mM, the partial muscarinic agonist Pilocarpine induces concentration-dependent relaxation in isolated rat tail artery segments that have been constricted with Penylephrine (10 to 200 nM)[3].

| ln Vivo |
Examined is the saliva secreted by the exercised (EX) and control (CN) rats in response to pilocarpine. Pilocarpine induces a considerably higher amount of saliva in the EX rats than in the CN rats (P<0.01). On the other hand, the EX rats' saliva had a considerably lower Na+ concentration than the CN rats' (P<0.05)[1].

Solubility in Formulation 1: ≥ 2.08 mg/mL (8.50 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (8.50 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
