产品描述 Description

Pilocarpine HCl is a miotic drug that acts as a M3-type muscarinic acetylcholine receptor (M3 muscarinic receptor) agonist, causing ciliary muscle contraction that opens up the trabecular meshwork which allows aqueous humour drainage and a resultant reduction in IOP[1]. Pilocarpine HCl is a hydrophilic drug used for managing IOP in the treatment of glaucoma[2]

Pilocarpine HCl encapsulated by liposomes can keep their integrity and physicochemical properties for at least 15 month[3].Pilocarpine HCl specifically inhibits Candida albicans biofilm formation and pathogenicity through interaction with a muscarinic-like receptor[4]. Pilocarpine HCl has acaricidal activity on larvae (LC50=2.6 mg?mL-1) and engorged females (LC50=11.8 mg?mL-1) of R.(B.) microplus[5]

Pilocarpine HCl have apparent functional protective effects in xerostomia models: an increase in the volume of saliva without any change in salivary content. This prophylactic action of pilocarpine HCl may provide a new clinical treatment for irradiation xerostomia in patients with head and neck cancer[6]. Oral activity responses to pilocarpine HCl are enhanced in neonatal 6-OHDA-treated rats[7]

盐酸毛果芸香碱是一种缩瞳药，作为 M3 型毒蕈碱型乙酰胆碱受体（M3 毒蕈碱受体）激动剂，引起睫状肌收缩，打开小梁网，允许房水排出，从而降低眼压 [1]。盐酸毛果芸香碱是一种亲水性药物，在治疗青光眼时用于控制眼压[2]

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

C.albicans SC5314

Preparation Method

Standardized C. albicans SC5314 (1×106 cells/ml) were inoculated in RPMI with or without Pilocarpine HCl on Thermanox coverslips (13mm) within a 24-well tissue culture plate and then incubated for 24h at 37℃.

Reaction Conditions

0-50mM

Applications

Light microscopy revealed that Pilocarpine HCl inhibited filamentation and biofilm formation in a dose-dependent manner. Furthermore, visually, in the presence of increasing concentrations of Pilocarpine HCl, more C.albicans cells maintained a yeast morphology, suggesting that Pilocarpine HCl was inhibiting the yeast-to-hypha transition. Scanning electron microscopy analysis further confirmed the fact that Pilocarpine HCl inhibited biofilm formation due to inhibition of the yeast-to-hypha transition in a dose-dependent manner.
Animal experiment [2]:

Animal models

Male Sprague-Dawley rats, seven-week-old

Preparation Method

Each rat was fasted overnight before the experiment, but had free access to drinking water. The rat was anaesthetized with urethane (1.25 g/kg, s.c.) and its body temperature was maintained at 37℃ during the subsequent experiment. After intubating the trachea, the duct of the right parotid gland was cannulated for the collection of saliva. Pilocarpine hydrochloride (0.05, 0.1, 0.2 or 0.4mg/kg in 1mL) or distilled water was administered intraduodenally and the saliva was collected for 120min after this administration

Dosage form

0.05, 0.1, 0.2 or 0.4mg/kg in 1mL

Applications

The mean salivary output for 120min without pilocarpine hydrochloride was 1.58±0.99μL (n=6). Pilocarpine hydrochloride (0.05-0.4mg/kg, intraduodenal) dose-dependently increased salivary output for 120 min in normal rats, the total volumes being 3.02±0.73 μL (0.05 mg/kg; n = 6), 3.91±0.50 μL (0.1 mg/kg; n = 6; P < 0.05 vs control), 5.74±0.99 μL (0.2 mg/kg; n = 6; P < 0.05 vs control) and 23.65±3.25 μL (0.4 mg/kg; n = 6; P < 0.05 vs control).
