Renal impairment: Lower initial doses and more gradual dosage increase.Hepatic impairment: Lower initial doses and more gradual dosage increase.
Hypersensitivity to phenothiazines, comatose states, pre-exisitng CNS depression, severe CVS disorders, uncorrected hypokalaemia or any electrolyte imbalance, known or suspected QT prolongation, history of ventricular arrhythmias including torsades de pointes and porphyria. Bone-marrow suppression, phaeochromocytoma, or prolactin-dependent tumours, angle-closure glaucoma, history of jaundice, parkinsonism, DM, hypothyroidism, myasthenia gravis, paralytic ileus, prostatic hyperplasia, or urinary retention. Patients with reduced activity of cytochrome P450 isoenzyme CYP2D6.
Drug Precautions ::
Pregnancy, lactation; renal or hepatic impairment, epilepsy. Perform ECG screening and electrolyte measurement before therapy, after each dose increase and at 6-mthly intervals. Monitor for visual defects on long-term therapy. May impair ability to perform skilled tasks. Withdrawal of drug to be carried out gradually over 1-2 wk.
Drug Side Effects ::
Drowsiness, sedation, dry mouth, nasal congestion, blurring of vision, tremor, mydriasis, constipation, urinary retention, tachycardia, postural hypotension, sexual dysfunction, pigmentary retinopathy (high doses and prolonged therapy), contact dermatitis, tardive dyskinesias. Potentially Fatal: Neuroleptic malignant syndrome. Sudden deaths due to cardiac arrhythmias and arrest.
Pregnancy category ::
Drug Mode of Action ::
Thioridazine, a phenothiazine antipsychotic, exhibits strong beta-adrenergic blocking effects and depresses the release of hypothalamic and hypophyseal hormones by blocking postsynaptic mesolimbic, dopaminergic receptors in the brain.
Drug Interactions ::
Potentiates adverse effects of anticholinergics. Concurrent use of TCAs leads to raised blood levels of both drugs. May antagonise effects of levodopa, bromocriptine and other dopamine agonists. Avoid co-admin with drugs that cause electrolyte imbalance. Monitor phenytoin therapy due to inconsistent effects of thioridazine on phenytoin levels. Potentially Fatal: Increased risk of QT prolongation with class IA and class II antiarrhythmics, astemizole, cisapride, pimozide, droperidol, erythromycin IV, sparfloxacin, terfenadine, clarithromycin and other drugs that may prolong QT interval. Potentiates CNS depression with opioids. Increased risk of arrhythmias with ephedrine-like drugs e.g. phenylpropanolamine. Increased thioridazone levels with fluovoxamine, pindolol, propranolol, ritonavir and other CYP2D6 isoenzymes inhibitors (e.g. fluoxetine, paroxetine).
