| | Anticholinergic drugs used in Parkinson's disease: An overlooked class of drugs from a pharmacokinetic perspective. |
 | | For example, in muscarinic receptors of rat brain, the IC values for atropine, benztropine, trihexyphenidyl, procyclidine, and orphenadrine were found to be 0.0022, 0.018, 0.026, 0.070, and 0.37 mM, respectively (8). |
 | | For example, in humans, Cmax of trihexyphenidyl have been reported to be 10 ng/mL (n=1 subject); 7.15±2.58 ng/ml (n=8 subjects), and approximately 50 ng/mL (n=2 subjects) after single oral doses of 2, 4, and 15 mg, respectively, of trihexyphenidyl HCl (9-11). |
 | | A recent paper has indicated that high tissue uptake of trihexyphenidyl and biperiden were facilitated by intralysosomal uptake of drug (23). |
