Oxybutynin is an anticholinergic medication used to relieve urinary and bladder difficulties, including frequent urination and inability to control urination, by decreasing muscle spasms of the bladder. It competitively antagonizes the M1, M2, and M3 subtypes of the muscarinic acetylcholine receptor.

Dược Lực Học : Oxybutynin is an antispasmodic, anticholinergic agent indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency, and frequency. Oxybutynin relaxes bladder smooth muscle. Oxybutynin exhibits only one-fifth of the anticholinergic activity of atropine on the rabbit detrusor muscle, but four to ten times the antispasmodic activity. Antimuscarinic activity resides predominantly in the R-isomer.
Cơ Chế Tác Dụng : Oxybutynin is an anticholinergic medication used to relieve urinary and bladder difficulties, including frequent urination and inability to control urination, by decreasing muscle spasms of the bladder. It competitively antagonizes the M1, M2, and M3 subtypes of the muscarinic acetylcholine receptor. Oxybutynin exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. No blocking effects occur at skeletal neuromuscular junctions or autonomic ganglia (antinicotinic effects). By inhibiting particularily the M1 and M2 receptors of the bladder, detrusor activity is markedly decreased.
Dược Động Học :
▧ Absorption :
Rapidly absorbed from gastrointestinal tract.
▧ Volume of Distribution :
* 193 L
▧ Protein binding :
91%-93%
▧ Metabolism :
Hepatic, primarily by CYP3A4
▧ Route of Elimination :
Oxybutynin is metabolized primarily by the cytochrome P450 enzyme systems, particularly CYP3A4, found mostly in the liver and gut wall. Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine. Also, less than 0.1% of the administered dose is excreted as the metabolite N-desethyloxybutynin.
▧ Half Life :
12.4-13.2 hours
Độc Tính : LD50=1220 mg/kg (Orally in rats, Goldenthal)
Chỉ Định : For the treatment of overactive bladder.
Tương Tác Thuốc :
  • Carbamazepine Oxybutynin may cause carbamazepine toxicity
  • Donepezil Possible antagonism of action
  • Galantamine Possible antagonism of action
  • Rivastigmine Possible antagonism of action
  • Tacrine The therapeutic effects of the central acetylcholinesterase inhibitor, Tacrine, and/or the anticholinergic, Oxybutynin, may be reduced due to antagonism. The interaction may be beneficial when the anticholinergic action is a side effect. Monitor for decreased efficacy of both agents.
  • Trimethobenzamide Trimethobenzamide and Oxybutynin, two anticholinergics, may cause additive anticholinergic effects and enhance their adverse/toxic effects. Monitor for enhanced anticholinergic effects.
  • Triprolidine Triprolidine and Oxybutynin, two anticholinergics, may cause additive anticholinergic effects and enhance their adverse/toxic effects. Monitor for enhanced anticholinergic effects.
  • Trospium Trospium and Oxybutynin, two anticholinergics, may cause additive anticholinergic effects and enhanced adverse/toxic effects. Monitor for enhanced anticholinergic effects.
