Латуда

Латуда Uses, Dosage, Side Effects, Food Interaction and all others data.

The efficacy of Латуда in schizophrenia could be mediated through a combination of central Dopamine D2 and Serotonin 5HT2A receptor antagonism.

Латуда is a benzothiazol derivative that is an antagonist and binds with high affinity to Dopamine-2 (D2) (Ki = 0.994 nM), 5-HT2A (Ki = 0.47 nM) receptors, and 5-HT7 receptors (Ki = 0.495 nM). It also binds with moderate affinity to alpha-2C adrenergic receptors (Ki = 10.8 nM) and is a partial agonist at 5-HT1A receptors (Ki = 6.38 nM). Its actions on histaminergic and muscarinic receptors are negligible.

Uses

Латуда Hydrochloride is an atypical antipsychotic. This is used for the treatment of: Schizophrenia, Depressive episodes associated with Bipolar I Disorder (bipolar depression), as monotherapy and as adjunctive therapy with lithium or valproate.

Латуда is also used to associated treatment for these conditions: Acute Depressive Episode, Schizophrenia

How Латуда works

Латуда is an atypical antipsychotic that is a D2 and 5-HT2A (mixed serotonin and dopamine activity) to improve cognition. It is thought that antagonism of serotonin receptors can improve negative symptoms of psychoses and reduce the extrapyramidal side effects that are often associated with typical antipsychotics.

Dosage

Латуда dosage

Schizophrenia-

  • Starting Dose: 40 mg once daily
  • Recommended Dose:40 mg to 160 mg once daily

Bipolar Depression-

  • Starting Dose:20 mg once daily
  • Recommended Dose:20 mg to 120 mg once daily

Латуда should be taken with food. Administration with food substantially increases the absorption of Латуда.

Side Effects

Somnolence, akathisia, extrapyramidal symptoms, and nausea.

Precaution

Cerebrovascular adverse reactions in elderly patients with dementia-related psychosis: Increased incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack).

Neuroleptic malignant syndrome: Manage with immediate discontinuation and close monitoring.

Tardive dyskinesia: Discontinue if clinically appropriate.

Metabolic changes: Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. These metabolic changes include hyperglycemia, dyslipidemia, and weight gain.

Hyperglycemia and diabetes mellitus: Monitor patients for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Monitor glucose regularly in patients with diabetes or at risk for diabetes.

Dyslipidemia: Undesirable alterations have been observed in patients treated with atypical antipsychotics.

Weight Gain: Gain in body weight has been observed. Monitor weight.

Hyperprolactinemia: Prolactin elevations may occur.

Leukopenia, neutropenia and agranulocytosis: Perform complete blood counts (CBC) in patients with a pre-existing low white blood cell count (WBC) or a history of leukopenia or neutropenia. Consider discontinuing Латуда if a clinically significant decline in WBC occurs in the absence of other causative factors.

Orthostatic hypotension and syncope: Dizziness, tachycardia or bradycardia, and syncope may occur, especially early in treatment. In patients with known cardiovascularor cerebrovascular disease, and in antipsychotic-naïve patients, consider a lower starting dose and slower titration.

Interaction

The Латуда dose should be reduced to half of the original level when used concomitantly with moderate inhibitors of CYP3A4 (e.g., Diltiazem, Atazanavir, Erythromycin, Fluconazole, Verapamil, etc.). If Латуда is used concomitantly with a moderate CYP3A4 inducer, it may be necessary to increase the Латуда dose.

Grapefruit: Grapefruit and grapefruit juice should be avoided in patients taking Латуда, since these may inhibit CYP3A4 and alter Латуда concentrations.

Food Interaction

  • Take with food. The manufacturer recommends co-administration with at least 350 calories.

[Major] GENERALLY AVOID: Grapefruit juice may significantly increase the plasma concentrations of lurasidone.

The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.

Inhibition of hepatic CYP450 3A4 may also contribute.

The interaction has not been studied with grapefruit juice, but has been reported for other CYP450 3A4 inhibitors.

When a single 10 mg dose of lurasidone was administered with the potent CYP450 3A4 inhibitor ketoconazole (400 mg

The AUC of lurasidone's active metabolite increased by 6-fold.

Another potent CYP450 3A4 inhibitor, posaconazole, has been reported to increase lurasidone AUC by approximately 4.5-fold.

When a single 20 mg dose of lurasidone was administered with the moderate CYP450 3A4 inhibitor diltiazem (extended release formulation 240 mg

In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands.

Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition.

GENERALLY AVOID: Alcohol may potentiate some of the central nervous system and hypotensive effects of lurasidone.

Use in combination may result in increased sedation, dizziness, hypotension, and impairment of judgment, thinking, and psychomotor skills.

ADJUST DOSING INTERVAL: Food increases the oral bioavailability of lurasidone.

According to the product labeling, lurasidone mean Cmax and AUC were increased approximately 3-fold and 2-fold, respectively, when administered with food relative to under fasting conditions.

Латуда AUC was not affected by meal size (in the range of 350 to 1000 calories) or fat content.

In clinical studies, lurasidone was administered with food.

MANAGEMENT: Patients treated with lurasidone should avoid consumption of grapefruit and grapefruit juice as well as alcohol.

Латуда should be taken with food (at least 350 calories).

Латуда Cholesterol interaction

[Moderate] Atypical antipsychotic drugs have been associated with undesirable alterations in lipid levels.

While all agents in the class have been shown to produce some changes, each drug has its own specific risk profile.

Before or soon after initiation of antipsychotic medication, obtain a fasting lipid profile at baseline and monitor periodically during treatment.

Volume of Distribution

6173 L

Elimination Route

Латуда is readily absorbed and quickly reaches maximal concentrations (Cmax) within 1-4 hours. When taken with food, there is a two-fold increase in exposure and time to maximal concentration is increased by 0.5-1.5 hours. This occurs regardless of fat or caloric content.
Bioavailability = 9-19%.

Clearance

3902 mL/min

Elimination Route

Urine (~9%) and feces (~80%)
