It works by relaxing the bladder muscles preventing bladder contraction
It acts by muscarinic receptor blockade in the bladder wall and detrusor muscle
In view of these adverse events with terodiline, patients in trials of tolterodine Tolterodine, sold under the brand name Detrol among others, is a medication used to treat frequent urination, urinary incontinence, or urinary urgency
The ER formulation has been evaluated extensively and has shown high efficacy with good safety and tolerability profiles
Prescribing information Antimuscarinics LUTS in men: Antimuscarinics (anticholinergics) Last revised in March 2019 Contraindications and cautions Adverse effects Drug interactions What are the contraindications and cautions for antimuscarinics? Do not prescribe an antimuscarinic drug to people with: Gastrointestinal obstruction or intestinal atony
Tolterodine shows functional selectivity for the bladder over the salivary glands in vivo, which is not attributable to muscarinic receptor subtype selectivity
Absolute oral bioavailability is variable (10-74%) and may depend on a patient's genetically determined ability to metabolize the drug
Three additional drugs were approved by the US Food and Drug Administration in 2004 to treat the symptoms of OAB: trospium, which has been in use in Europe for the treatment of OAB, darifenacin, Table 1
5 mg, 3 mg, and 5 mg) 5 mg two or three times a day, increasing to a maximum of 5 mg four times a day
e Tolterodine is a competitive muscarinic receptor antagonist available in an IR and ER formulation
Antimuscarinic treatment is not always effective and is associated with side-effects that limit its clinical use
30943
This activity will highlight the mechanism Currently, oxybutynin, tolterodine, solifenacin, darifenacin and trospium are the five major antimuscarinic drugs that are employed for the treatment of OAB
54% of reviewers reported a positive effect, while 24% reported a negative effect
Mechanism of Action
Tolterodine is an antimuscarinic drug that is used to treat urinary incontinence
Introduction Overactive bladder (OAB) is a common condition, increasing with age and affecting quality of life
The use of fesoterodine fumarate, like other antimuscarinic drugs, in patients with clinically significant bladder outlet obstruction, including patients with urinary retention, may result in further urinary retention and kidney injury
71)
Such high concentrations of tolterodine and 5-HM in the bladder may be attributable to the tissue selectivity of this drug
Oxybutynin was evaluated in four studies involving a total of 315 subjects, and was consistently associated with Older antimuscarinic agents used for the management of OAB are oral oxybutynin (Ditropan ® and Ditropan XL ®, Ortho-McNeil), transdermal oxybutynin (Oxytrol ®, Watson Pharmaceuticals) and oral tolterodine (Detrol ®®, Pfizer)
The active moiety, tolterodine, is a muscarinic receptor antagonist
The aim of the present study was to compare the antimuscarinic properties of tolterodine with those of oxybutynin, in vitro and in vivo
The cognitive changes observed are caused by the drugs' ability to cross the blood-brain barrier and bind to muscarinic receptors within the central nervous system (CNS)
This M3 selective muscarinic antagonist acts preferentially on the urinary bladder and is less likely to cause dry mouth and other anticholinergic side effects Drug group or drug name: Drug examples: What can happen : antimuscarinic drugs • oxybutynin ()• solifenacin (Vesicare) • tolterodine ()can increase the risk of urinary retention (difficulty The muscarinic antagonist is a class medication used to manage and treat numerous conditions, including COPD and organophosphate toxicity
Key words: Antimuscarinic drugs, CNS adverse events, Cognitive impairment, Elderly, Overactive bladder
Signs may include swelling of the hands, face, lips, eyes, tongue, or throat; trouble breathing; trouble swallowing; or unusual hoarseness
The effects on these and other muscarinic receptors are responsible for the side effects associated with these agents
[ 5 , 6 ] Prior to the introduction of tolterodine, the most commonly used antimuscarinic agent was oxybutynin
Tolterodine is a medicine used to treat symptoms of an overactive bladder
Both urinary bladder contraction and salivation are mediated via cholinergic muscarinic receptors
The chemical
Tolterodine (tol ter' oh deen) is a synthetic anticholinergic and antispasmotic agent that inhibits muscarinic actions of acetylcholine on autonomic nerve endings, decreasing secretions and inhibiting
Tolterodine is a competitive muscarinic receptor antagonist
Acetylcholine causes acts on muscarinic receptors and stimulates detrusor contraction
This drug serves as a gold standard treatment for OAB, is regarded as the third most favorable antimuscarinic, and has a decreased level of adverse effects
If you experience any of the following symptoms stop taking tolterodine and call your doctor immediately or get emergency medical treatment: swelling of the face, throat, tongue, lips, and eyes
54% of reviewers reported a positive effect, while 24% reported a negative effect
Mechanism of Action
Effect of tolterodine on other drugs metabolized by Cytochrome P450 enzymes: Inform patients that antimuscarinic agents such as tolterodine tartrate extended-release capsules may have side effects including blurred vision, dizziness, or drowsiness
Tolterodine is a tertiary amine
In a 1-year study based on the UK General Practice longitudinal prescription database, < 25% of patients remained on the initially prescribed
Chemically, fesoterodine The relationship of her reported language disturbance to tolterodine was unclear since we had no objective documentation of this report
66) and less risk of dry mouth (RR 0
Efficacy of tolterodine In four studies of tolterodine2 (two studies comparing it with immediate-release oxybu-tynin and two studies comparing it with placebo), tolterodine met the goal of reducing the frequency of urination by about 20%, sim-ilar to immediate-release oxybutynin
In conclusion, oral tolterodine binds significantly to muscarinic receptors in the mouse bladder, and the receptor binding activity of this drug compared with oral oxybutynin is relatively slow and longer lasting
In 2004, the United States Food and Drug Administration (FDA) approved three additional antimuscarinic
