Pridinol 

Pridinol is an orally active, blood-brain permeable, muscarinic acetylcholine receptor (mAChR)-directed muscle relaxant. Pridinol reduces the conduction of impulses to spinal motor neurons and exerts muscle relaxant activity. Pridinol inhibits skeletal muscle contractures in diseases of both central and peripheral origin and can be used in research in the field of musculoskeletal diseases^[1][2].

The in vitro dissolution characteristics of Pridinol are slightly affected by pH (pH 1.2, 4.5, 6.8)^[1].
The lower limit of detection of Pridinol in biological samples is 0.0500 ng/mL and the upper limit is 50 ng/mL^[1].
