🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by blocking muscarinic acetylcholine receptors, particularly the M3 subtype, on the smooth muscle of the urinary bladder. Acetylcholine is a chemical messenger that normally stimulates the bladder muscle to contract, causing the urge to urinate. By blocking these receptors, this medicine reduces involuntary bladder contractions, allowing the bladder to hold more urine and decreasing episodes of urgency and leakage. It also reduces secretions from salivary glands, which explains the common side effect of dry mouth.
Mechanism Steps
💡 How to Take cystran 2.5 tablet
Strength: Immediate-release tablet containing 2.5 mg of oxybutynin.
Dosage Information
| Adult Dosage | The usual starting dose of this medicine for adults is 2.5 mg taken two to three times daily. Your doctor may gradually increase the dose based on your response and tolerability, up to a maximum of 5 mg three times daily (15 mg per day). The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not adjust the dose without consulting your doctor. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Older adults (above 65 years) are more sensitive to the anticholinergic effects of this medicine, including confusion, constipation, and urinary retention. The starting dose should be low, and dose increases should be made cautiously. Regular monitoring for cognitive and urinary side effects is recommended. |
| Renal Impairment | No specific dose adjustment is provided in the product literature for renal impairment. However, because oxybutynin is excreted by the kidneys, caution is advised in patients with severe renal impairment. Dose adjustment should be individualized by a clinician based on clinical response and tolerability. |
| Hepatic Impairment | Oxybutynin is extensively metabolised in the liver. In patients with mild to moderate hepatic impairment, no dose adjustment is typically required. In severe hepatic impairment, the dose should be reduced or used with caution, as the half-life may be prolonged. Individualize the dose based on clinical response. |
| Maximum Daily Dose | The maximum recommended daily dose for adults is 15 mg per day (5 mg three times daily) of the immediate-release formulation. |
