Precaution

The administration of general anesthetics to patients receiving Alfuzosin could cause profound hypotension. It is recommended that the tablets be withdrawn 24 hours before surgery. If symptoms of angina pectoris start or get worse, taking Alfuzosin should be stopped.

Interaction

Combinations contra-indicated: Alpha-1-receptor blockers. Combinations to be taken into account: Antihypertensive drugs, nitrates, potent CYP3A4 inhibitors such as ketoconazole, itraconazole and ritonavir. Repeated 200mg daily dosing of ketoconazole, for seven days resulted in a 2.1-fold increase in Cmax and a 2.5-fold increase in exposure of Uriten Tablet (Extended Release) 10 mg 10mg when administered as a single dose under fed conditions (high fat meal). Other parameters such as tmax and t1/2 were not modified. Cmax and AUC of Uriten Tablet (Extended Release) 10 mg 10mg, when administered as a single dose under fed conditions, increased 2.3- fold and 3.0- fold, respectively following 8-day repeated 400mg ketoconazole daily dosing. The administration of general anaesthetics to patients receiving Uriten Tablet (Extended Release) 10 mg could cause profound hypotension. It is recommended that the tablets be withdrawn 24 hours before surgery.Other forms of interaction: No pharmacodynamic or pharmacokinetic interaction has been observed in healthy volunteers between Uriten Tablet (Extended Release) 10 mg and the following drugs: warfarin, digoxin, hydrochlorothiazide and atenolol.

Pregnancy & Breastfeeding use

Due to the type of indication this is not applicable.

Contraindication

As with all alpha-1-blockers in some subjects, in particular patients receiving antihypertensive medications or nitrates, postural hypotension with or without symptoms (dizziness, fatigue, sweating) may develop within a few hours following administration. In such cases, the patient should lie down until the symptoms have completely disappeared. These effects are transient, occur at the beginning of treatment and do not usually prevent the continuation of treatment. The patient should be warned of the possible occurrence of such events. As with all alpha1-receptor blockers, Uriten Tablet (Extended Release) 10 mg should be used with caution in patients with acute cardiac failure. Care should be taken when Uriten Tablet (Extended Release) 10 mg is administered to patients who have had a pronounced hypotensive response to another alpha-1-blocker. Treatment should be initiated gradually in patients with hypersensitivity to alpha-1-blockers. Uriten Tablet (Extended Release) 10 mg should be administered carefully to patients being treated with antihypertensives. Blood pressure should be monitored regularly, especially at the beginning of treatment. Patients with congenital QTc prolongation, with a known history of acquired QTc prolongation or who are taking drugs known to increase the QTc interval should be evaluated before and during the administration of Uriten Tablet (Extended Release) 10 mg. In coronary patients, the specific treatment for coronary insufficiency should be continued. If angina pectoris reappears or worsens Uriten Tablet (Extended Release) 10 mg should be discontinued. As there are no clinical safety data available in patients with severe renal impairment (creatinine clearance < 30ml/min), Uriten Tablet (Extended Release) 10 mg 10mg prolonged released tablets should not be administered to this patient group. Patients should be warned that the tablet should be swallowed whole. Any other mode of administration, such as crunching, crushing, chewing, grinding or pounding to powder should be prohibited. These actions may lead to inappropriate release and absorption of the drug and therefore possible early adverse reactions. The ‘Intraoperative Floppy Iris Syndrome’ (IFIS, a variant of small pupil syndrome) has been observed during cataract surgery in some patients on or previously treated with alpha-1-blockers. Although the risk of this event with Uriten Tablet (Extended Release) 10 mg appears very low, ophthalmic surgeons should be informed in advance of cataract surgery of current or past use of alpha-1-blockers, as IFIS may lead to increased procedural complications. The ophthalmologists should be prepared for possible modifications to their surgical technique. Uriten Tablet (Extended Release) 10 mg 10mg prolonged release tablets contain hydrogenated castor oil which may cause stomach upset and diarrhoea.

Acute Overdose
