Inn (Generic Name)
Vitria does not have an established International Nonproprietary Name (INN). The nearest recognized drug name is Vitravene, which contains the active ingredient fomivirsen. This medication is primarily utilized for treating cytomegalovirus (CMV) retinitis, especially in patients with AIDS. As of recent reviews, there is no evidence to support “Vitria” as an accepted medicinal product within major pharmaceutical databases or regulatory agencies, including the ANMDMR (National Agency for Medicines and Medical Devices of Romania).
Brand Names In Canada
In the Canadian market, “Vitria” is not recognized. Instead, Vitravene remains the primary branding under which fomivirsen is available. Since 2025, there has been no indication of "Vitria" being marketed or packaged; thus, healthcare practitioners and patients are directed to the existing product range, primarily focusing on Vitravene as a sole option for treatment related to CMV.
Atc Code & Dosage Forms
The ATC (Anatomical Therapeutic Chemical) classification for Vitravene is denoted as S01AD08, which indicates it falls under the category of ophthalmologicals, specifically as an antiviral medication.
The dosage form available is intravitreal injection, with a standard dosage of 330 μg per vial. This forms the main route of administration for patients suffering from CMV retinitis, allowing the drug to exert its therapeutic effects directly where needed in the eye.
Manufacturers & Registration Status
Vitravene was developed by ISIS Pharmaceuticals, which is now known as Ionis Pharmaceuticals. Although this medication received FDA approval previously, it was withdrawn from both U.S. and EU markets due to diminishing use linked to advancements in antiretroviral therapies that effectively reduced CMV retinitis incidents. Currently, there are no registered details regarding “Vitria” in Canada or Europe, making its status unclear.
Otc / Rx Classification
As for its classification, Vitravene is categorized as a prescription-only medication (Rx). It is vital for patients to consult healthcare providers to access this specific treatment for CMV-related eye conditions, ensuring proper monitoring and support due to its specific application.
Dosage & Administration for Vitravene
Understanding the dosing of Vitravene, especially for adult CMV retinitis, is crucial. The standard regimen includes:
- Induction Phase: 330 μg by intravitreal injection once weekly for three weeks.
- Maintenance Phase: 330 μg by intravitreal injection every other week.
Patients and caregivers should adhere to this schedule closely to maintain effective treatment.
Adjustments Based on Patient Factors
Considerations may need to be made based on patient demographics. For example, there’s little data on Vitravene's use in pediatric populations, so it is primarily indicated for adult use. Although adjustments for elderly patients haven’t been explicitly published, clinicians are encouraged to apply their judgment, monitoring for any potential side effects. When it comes to renal or hepatic impairment, the local intravitreal injection reduces systemic exposure, thus, guidelines around these factors remain minimal.
Treatment Duration, Storage, and Transport of Vitravene
Typically, treatment with Vitravene lasts as long as active CMV retinitis poses a risk to vision. Regular monitoring by an eye specialist is recommended to evaluate treatment effectiveness.
In terms of storage, Vitravene should be kept at a temperature range of 2–8°C (refrigerated), away from direct light and freezing conditions. For transport, maintaining controlled, refrigerated conditions is necessary, ensuring the medication remains effective until administration.
Safety & Warnings for Vitravene
Using Vitravene does come with its share of cautions. Patients must be aware of both absolute and relative contraindications. Absolute contraindications include:
- Hypersensitivity to fomivirsen or its components.
- Active ocular infections at the injection site.
Relative contraindications may involve severe local ocular inflammation, where monitoring of intraocular pressure is critical. Always consult a physician if any pre-existing conditions could affect treatment.
Common and Severe Side Effects
Like any medication, Vitravene does carry side effects. Commonly reported effects are mild to moderate, such as:
- Eye inflammation (iritis, vitritis)
- Increased intraocular pressure
- Cataract formation in the anterior chamber
- Ocular discomfort or pain
However, for certain populations, such as the elderly or those with compromised immune systems, the risks of severe side effects may be higher. Close monitoring is essential for these patients to address issues quickly.
Special Precautions with Vitravene
In special cases, particularly during pregnancy or in individuals with liver impairment, using Vitravene may require extra precautions. Pregnant women should only use the medication if clearly needed, as safety hasn’t been ensuring thorough testing in this group.
For patients with liver issues, careful monitoring is essential, despite the minimal systemic absorption from the local injection. Maintaining awareness of potential side effects should remain a priority for healthcare providers.
