detrustitol retard
detrustitol retard Uses, Dosage, Side Effects, Food Interaction and all others data.
detrustitol retard is a competitive, specific muscarinic receptor antagonist which exhibits a selectivity for the urinary bladder over salivary glands, which have been demonstrated in non clinical pharmacological in vivo studies. detrustitol retard has a high specificity for muscarinic receptors. A major active metabolite (5-hydroxymethyl derivative) of tolterodine exhibits a pharmacological profile which is similar to that of the parent compound. In extensive metabolisers this metabolite contributes significantly to the therapeutic effect of tolterodine. The effect of treatment can be expected within 4 weeks.
detrustitol retard is a competitive muscarinic receptor antagonist. Both urinary bladder contraction and salivation are mediated via cholinergic muscarinic receptors. After oral administration, tolterodine is metabolized in the liver, resulting in the formation of the 5-hydroxymethyl derivative, a major pharmacologically active metabolite. The 5-hydroxymethyl metabolite, which exhibits an antimuscarinic activity similar to that of tolterodine, contributes significantly to the therapeutic effect. Both tolterodine and the 5-hydroxymethyl metabolite exhibit a high specificity for muscarinic receptors, since both show negligible activity or affinity for other neurotransmitter receptors and other potential cellular targets, such as calcium channels. detrustitol retard has a pronounced effect on bladder function. The main effects of tolterodine are an increase in residual urine, reflecting an incomplete emptying of the bladder, and a decrease in detrusor pressure, consistent with an antimuscarinic action on the lower urinary tract.

Uses
detrustitol retard Tartrate is used for the treatment of overactive bladder with symptoms of urinary urgency, frequency, and/or urge incontinence.
detrustitol retard is also used to associated treatment for these conditions: Urinary Bladder, Overactive
How detrustitol retard works
Both tolterodine and its active metabolite, 5-hydroxymethyltolterodine, act as competitive antagonists at muscarinic receptors. This antagonism results in inhibition of bladder contraction, decrease in detrusor pressure, and an incomplete emptying of the bladder.
Dosage
detrustitol retard dosage
The recommended dose for tolterodine is 2 mg twice daily. In case of troublesome side effects the dose may be reduced from 2 mg to 1 mg twice daily.
The recommended total daily dose of tolterodine is 2 mg (1 mg b.i.d.) for patients with impaired renal function, impaired liver function, or receiving concomitant medication with potent CYP3A inhibitors, such as macrolide antibiotics (e.g. erythromycin and clarithromycin) or azole antifungal agents (e.g. ketoconazole, itraconazole and miconazole). After six months the need for further treatment should be considered.
Side Effects
detrustitol retard may cause mild to moderate antimuscarinic effects, like dryness of mouth, dyspepsia and/or reduced lacrimation.
Precaution
detrustitol retard should be used with caution in the following patients:
- at risk for urinary retention
- at risk for decreased gastrointestinal motility
- with impaired renal function
- with impaired hepatic function
Organic reasons for urge and frequency should be considered before treatment.
Interaction
Pharmacokinetic interactions are possible with other drugs metabolised by or inhibiting cytochrome P450 2D6 (CYP2D6) or CYP3A4. Concomitant treatment with fluoxetine does not result in a clinically significant interaction.
Ketoconazole, a potent inhibitor of CYP3A, significantly increased plasma concentrations of tolterodine when coadministered to poor metabolisers (i.e. persons devoid of CYP2D6 metabolic pathway).
Clinical studies have shown no interactions with warfarin or combined oral contraceptives (ethinyloestradiol or levonorgestrel).
Food Interaction
- Take with food.
detrustitol retard Alcohol interaction
[Moderate] GENERALLY AVOID:
Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous.
In addition, the potential for abuse may be increased with the combination.
The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system.
No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load.
However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.
Alcohol should generally be avoided during therapy with anticholinergic agents.
Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.

Volume of Distribution
- 113 ± 26.7 L
Half Life
1.9-3.7 hours
Elimination Route
Following administration of a 5-mg oral dose of 14C-tolterodine solution to healthy volunteers, 77% of radioactivity was recovered in urine and 17% was recovered in feces in 7 days.
Pregnancy & Breastfeeding use
There are no studies in pregnant women. Therefore, tolterodine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Use of tolterodine during lactation should be avoided since no data on excretion of the drug into breast milk in humans is available.
Contraindication
detrustitol retard is contraindicated in those patients with urinary retention, uncontrolled narrow angle glaucoma, known hypersensitivity to tolterodine or any other component of the drug.
Special Warning
Pediatric use: Safety and effectiveness of tolterodine in children have not been established.
Geriatric use: No overall differences in safety were observed between the older and younger patients treated with detrustitol retard.
Acute Overdose
Overdosage with detrustitol retard Tartrate capsules can potentially result in severe central anticholinergic effects and should be treated accordingly. ECG monitoring is recommended in the event of overdosage.
Storage Condition
Store in a cool and dry place. Protect from light. Keep out of the reach of children.
