Typically, HCMV causes asymptomatic infection in the immunocompetent population, while in immunocompromised individuals or when transmitted vertically from the mother to the fetus it leads to systemic disease with severe complications and high mortality rate. Following primary infection, HCMV establishes a state of latency primarily in myeloid cells, from which it can be reactivated by various inflammatory stimuli. Several studies have shown that HCMV, despite being a DNA virus, is highly prone to genetic variability that strongly influences its replication and dissemination rates as well as cellular tropism. In this scenario, the few currently available drugs for the treatment of HCMV infections are characterized by high toxicity, poor oral bioavailability, and emerging resistance.

    ANNEX I SUMMARY OF PRODUCT CHARACTERISTICS 4 1. NAME OF THE MEDICINAL PRODUCT VISTIDE 2. QUALITATIVE AND QUANTITATIVE COMPOSITION Each vial contains cidofovir equivalent to 375 mg/5 ml (75 mg/ml) cidofovir anhydrous. The formulation is adjusted to pH 7.4. 3. PHARMACEUTICAL FORM Concentrate for solution for infusion 4. CLINICAL PARTICULARS 4.1 Therapeutic Indication Cidofovir is indicated for the treatment of CMV retinitis in patients with acquired immunodeficiency syndrome (AIDS) and without renal dysfunction. Until further experience is gained, cidofovir should be used only when other agents are considered unsuitable. 4.2 Posology and Method of Administration Before each administration of cidofovir, serum creatinine and urine protein levels should be investigated. The recommended dosage, frequency, or infusion rate must not be exceeded. Cidofovir must be diluted in 100 milliliters 0.9% (normal) saline prior to administration. To minimise potential nephrotoxicity, oral probenecid and intravenous saline prehydration must be administered with each cidofovir infusion. Dosage in Adults • Induction Treatment. The recommended dose of cidofovir is 5 mg/kg body weight (given as an intravenous infusion at a constant rate over 1 hr) administered once weekly for two consecutive weeks. • Maintenance Treatment. Beginning two weeks after the completion of induction treatment, the recommended maintenance dose of cidofovir is 5 mg/kg body weight (given as an intravenous infusion at a constant rate over 1 hr) administered once every two weeks. Cidofovir therapy should be discontinued and intravenous hydration is advised if serum creatinine increases by = 44 µmol/L (= 0.5 mg/dl), or if persistent proteinuria = 2+ develops. • Probenecid.

    Cheong et al. BMC Gastroenterology (2020) 20:305 https://doi.org/10.1186/s12876-020-01452-3 CASE REPORT Open Access “Black box warning” rash with entecavir - case report Xiong Khee Cheong1, Zhiqin Wong2*, Norazirah Md Nor3 and Bang Rom Lee4 Abstract Background: Hepatitis B infection is a significant worldwide health issue, predispose to the development of liver cirrhosis and hepatocellular carcinoma. Entecavir is a potent oral antiviral agent of high genetic barrier for the treatment of chronic hepatitis B infection. Cutaneous adverse reaction associated with entecavir has rarely been reported in literature. As our knowledge, this case was the first case reported on entecavir induced lichenoid drug eruption. Case presentation: 55 year old gentlemen presented with generalised pruritic erythematous rash on trunk and extremities. Six weeks prior to his consultation, antiviral agent entecavir was commenced for his chronic hepatitis B infection. Skin biopsy revealed acanthosis and focal lymphocytes with moderate perivascular lymphocyte infiltration. Skin condition recovered completely after caesation of offending drug and short course of oral corticosteroids. Conclusion: This case highlight the awareness of clinicians on the spectrum of cutaneous drug reaction related to entecavir therapy.

For the full list of excipients, see section 6.1. 3. Pharmaceutical Form A pink film-coated, oval, biconvex, beveled edge tablet debossed with “ M” on one side of the tablet and “ V45 ” on the other side. 4. Clinical Particulars 4.1 Therapeutic indications Valganciclovir Mylan is indicated for the treatment of cytomegalovirus (CMV) retinitis in acquired immunodeficiency syndrome (AIDS) patients. Valganciclovir Mylan Is indicated for the prevention of CMV disease in solid organ transplant patients at risk. 4.2 Dose and method of administration Caution – Strict adherence to dosage recommendations is essential to avoid overdose. Standard dosage Valganciclovir Mylan is administered orally and should be taken with food (see section 5.1). Valganciclovir Mylan is rapidly and extensively converted into the active ingredient ganciclovir. The bioavailability of ganciclovir from valganciclovir is up to 10-fold higher than from oral ganciclovir. The dosage and administration of Valganciclovir Mylan tablets as described below should be closely followed (see section 4.4). Treatment of cytomegalovirus (CMV) retinitis Adult patients Induction treatment of CMV retinitis For patients with CMV retinitis, the recommended dose is 900 mg (two 450 mg tablets) with food twice a day for 21 days. Prolonged induction treatment may increase the risk of bone marrow toxicity (see section 4.4).

  • Ganciclovir (Cytovene®)
    Ganciclovir (Cytovene®) Class: Ganciclovir is a nucleoside analogue of guanosine and a homologue of acyclovir. Valganciclovir is the valyl ester prodrug of ganciclovir Antiviral Activity: Ganciclovir has activity against nearly all herpesviruses. It has little activity against vaccina virus, human papilloma virus, or RNA viruses such as influenza A. Its main use is in the treatment and/or prophylaxis of CMV infection in immunocompromised patients. Mechanism of Action: Ganciclovir is phosphorylated to its triphosphate form (ganciclovir triphosphate), which competitively inhibits incorporation of deoxyguanosine triphosphate into elongating DNA. Short subgenomic CMV DNA fragments continue to be synthesized in the presence of ganciclovir. These DNA fragments are not packaged into virions and are therefore not considered infectious. Mechanism of Resistance: Mutations producing an inability to phosphorylate ganciclovir are the most common mechanism of resistance. Pharmacokinetics: Intravenous ganciclovir achieves higher Cmax values then oral ganciclovir. However, oral ganciclovir produces serum concentrations that are more sustained over the course of the day. The absolute bioavailability of oral ganciclovir is approximately 8.5%. The absolute bioavailability of ganciclovir from administration of valganciclovir tablets with food is approximately 60%. The plasma protein binding of ganciclovir is negligible (<2%). The kidneys are the primary route of elimination for ganciclovir. Adverse Effects: The main dose-limiting adverse effect is bone marrow

HCMV infection is extremely common in human populations and can cause severe resistance; diseases in immunocompromised hosts. Ganciclovir is the most widely used antiviral drug for ganciclovir cytomegalovirus infection and works by blocking the amplification of HCMV. HCMV strains resis- tant to ganciclovir have been detected in recent decades and mainly result from mutations in UL97 (protein kinase) and UL54 (DNA polymerase) genes. In order to understand the prevalence of resistance of HCMV in Taiwan, we studied 40 clinical isolates to detect the mutations of UL97 and UL54 that might be related to resistance. The results showed that no mutation known to cause ganciclovir resistance was detected in any strain, but some polymorphisms (N685S, A688V, A885T, N898D in UL54; D605E in UL97) were frequently observed.
