Urodynamic results in these patients were consistent with the clinical results. Among the various anticholinergics, oxybutynin carried the highest risk of dementia. Oxybutynin is an anticholinergic drug for overactive bladder. It also comes as a 60-mg extended-release capsule that you take once per day. It’s available in many strengths, including 1-mg and 2-mg tablets or 2-mg and 4-mg capsules. Table 3 shows the incidence of adverse events judged by investigators to be at least possibly related to treatment and reported by at least 5% of patients.The most common adverse events reported by patients receiving Oxybutynin chloride 5-20 mg/day were the expected side effects of anticholinergic agents. In fact, you may not feel the full effect of fesoterodine for If you don’t respond to small doses of other bladder control drugs, your doctor may recommend trospium. According to the Mayo Clinic, OAB may cause you to urinate at least If you do have OAB, it can affect your quality of life. Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle. A lower starting dose of 2.5 mg two or three times a day is recommended for the frail elderly.Pediatric patients over 5 years of age: The usual dose is one 5-mg tablet two times a day. Oxybutynin therapy is not associated with QTc interval prolongation and is unlikely to produce ventricular arrhythmias. The incidence of dry mouth was dose-related.In addition, the following adverse events were reported by 1 to <5% of patients using Oxybutynin chloride (5-20 mg/day) in all studies. Because postmarketing adverse events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Its metabolic products include phenylcyclohexylglycolic acid, which is pharmacologically inactive, and desethylOxybutynin, which is pharmacologically active.Oxybutynin is extensively metabolized by the liver, with less than 0.1% of the administered dose excreted unchanged in the urine.

It is freely soluble in water and in alcohol; very soluble in methanol and in chloroform; soluble in acetone; slightly soluble in ether; very slightly soluble in hexane.Oxybutynin Chloride Tablets, USP also contain magnesium stearate, microcrystalline cellulose, and pregelatinized starch.Oxybutynin Chloride Tablets, USP are for oral administration.Therapeutic Category: Antispasmodic, anticholinergic.FDA approved dissolution test specifications differ from USP.Oxybutynin chloride exerts a direct antispasmodic effect on smooth muscle and inhibits the muscarinic action of acetylcholine on smooth muscle.
1. Oxybutynin chloride thus decreases urgency and the frequency of both incontinent episodes and voluntary urination.Antimuscarinic activity resides predominately in the R-isomer.
Activated charcoal as well as a cathartic may be administered.Overdosage with Oxybutynin chloride has been associated with anticholinergic effects including central nervous system excitation (e.g., restlessness, tremor, irritability, convulsions, delirium, hallucinations), flushing, fever, dehydration, cardiac arrhythmia, vomiting, and urinary retention. Healthline Media does not provide medical advice, diagnosis, or treatment. It is not known if oxybutynin, a drug with a similar pharmacological profile, causes QT prolongation. Both patients fully recovered with symptomatic treatment.Adults: The usual dose is one 5-mg tablet two to three times a day. The plasma concentration-time profiles for R- and S-Oxybutynin are similar in shape; Figure 1 shows the profile for R-Oxybutynin.Oxybutynin chloride steady-state pharmacokinetics was also studied in 11 pediatric patients with detrusor overactivity associated with a neurological condition (e.g., spina bifida).

It’s available in the following forms: oral tablet (Ditropan, Ditropan XL)
This study demonstrates the inhibitory effect of anticholinergic drug oxybutynin on voltage‐dependent K + (Kv) channels in rabbit coronary arterial smooth muscle cells.
