Background

Procyclidine is an antagonist of muscarinic acetylcholine receptors (K_is = 4.47, 42.66, 7.24, 6.03, and 4.79 nM for M_1-5 receptors, respectively).¹ It increases fine motor activity counts (ED₅₀ = 1.74 mg/kg) without affecting ambulatory activity in rats in a home-cage activity test.² Formulations containing procyclidine have been used in the treatment of parkinsonism and extrapyramidal dysfunction.

Protocol

Animal experiment:

Rats[1] Adult Sprague-Dawley female rats (weight 300-330 g) are used. Procyclidine given systemically causes a transient increase in locomotor activity (mainly non-ambulatory fine movements) in adult rats. Locomotor activity data (ambulations, fine movements) are evaluated using a two-way ANOVA to test whether co-administration of clonidine (0.025 mg/kg) with various doses of Procyclidine (10, 25, 50 and 75 mg/kg) altered the activity levels compared to the same doses of Procyclidine administered alone. A one-way ANOVA and subsequent comparisons are also conducted to establish whether the activity levels for each treatment group are different from saline controls.
