リバビリン 化学特性,用途語,生産方法

用途

ウィルス RNA ポリメラーゼ を阻害し、ウィルスの増殖阻害作用を示しま す。

用途

リバビリン(Ribavirin)は、抗ウイルス薬の一つで、主にC型肝炎やウイルス性出血熱等の治療で施行されている。

化学的特性

Colourless Solid

使用

Purine nucleoside analog; inhibits inosine monophosphate dehydrogenase (IMPDH). Used as an antiviral agent.

使用

aldosterone antagonist; antifibrogenic

使用

anti-infective, anti-fungal

使用

A broad spectrum antiviral nucleoside and inhibitor of inosine monophosphate dehydrogenase.

定義

ChEBI: A 1-ribosyltriazole that is the 1-ribofuranosyl derivative of 1,2,4-triazole-3-carboxamide. An inhibitor of HCV polymerase.

使用

Ribavirin is a guanosine analog with antiviral properties against DNA and RNA viruses, including respiratory syncytial virus, hepatitis C, and influenza. It acts as a prodrug that can be activated by either mono- or tri-phosphorylation by cellular kinases. These phosphorylated derivatives of ribavirin have diverse effects on both cellular and viral enzymes, resulting in suppression of viral replication.

brand name

Copegus (Roche); Rebetol (Schering); Virazole (Valeant).

獲得抵抗性

Development of resistant virus strains has not been demonstrated.

一般的な説明

White powder. Exists in two polymorphic forms.

空気と水の反応

Water soluble.

反応プロフィール

Ribavirin may be sensitive to prolonged exposure to light.

危険性

Mildly toxic by ingestion. An experimental teratogen.

火災危険

Flash point data for Ribavirin are not available; however, Ribavirin is probably combustible.

応用例(製薬)

A synthetic nucleoside. It is neither a classic pyrimidine nor a purine, but stereochemical studies indicate that it is a guanosine analog. It is usually formulated for administration by inhalation, but oral and intravenous preparations are also used.

薬物動態学

Oral absorption: 36–46%
Cmax 3 mg/kg oral: 4.1–8.2 μmol/L after 1–1.5 h
600 mg intravenous: 43.6 μmol/L end infusion
Plasma half-life: c. 24 h
Volume of distribution: 647 L
Plasma protein binding: <10%
Absorption
It is rapidly absorbed after oral administration. Mean peak concentrations after 1 week of oral doses of 200, 400 and 800 mg every 8 h were 5.0, 11.1 and 20.9 μmol/L, respectively. Trough levels 9–12 h after the end of 2 weeks’ therapy were 5.1, 13.2 and 18.4 μmol/L, respectively, indicating continued accumulation of the drug. Drug was still detectable 4 weeks later. Mean peak plasma concentrations after intravenous doses of 600, 1200 and 2400 mg were 43.6, 72.3 and 160.8 μmol/L, respectively; at 8 h the mean plasma concentrations were 2.1, 5.6 and 10.2 μmol/L. Aerosolized doses (6 g in 300 mL distilled water) are generally administered at a rate of 12–15 mL/h using a Collison jet nebulizer, the estimated dosage being 1.8 mg/kg per h for infants and 0.9 mg/kg per h for adults. When administered by small particle aerosol for 2.5–8 h, plasma concentrations ranged from 0.44 to 8.7 μmol/L.
Metabolism and excretion
It is rapidly degraded by deribosylation or amide hydrolysis, and together with its metabolites is slowly eliminated by the kidney. About 50% of the drug or its metabolites appear in the urine within 72 h and 15% is excreted in the stools. The remainder seems to be retained in body tissues, principally in red blood cells, which concentrate the drug or metabolites to a peak at 4 days, with a half-life of around 40 days. After intravenous administration 19.4% of the dose was eliminated during the first 24 h (compared with 7.3% after an oral dose), the difference reflecting the bioavailability.

臨床応用

RSV infections in infants (by nebulizer) in emergency situations (i.e. transplant recipients)
Lassa fever
Hepatitis C (in combination with interferon-α)
Use in RSV pneumonia in infants is no longer routine. It reduces mortality from Hantaan virus, the agent responsible for hemorrhagic fever with renal syndrome.

副作用

It is generally well tolerated, though adverse reactions appear to be related to dose and duration of therapy. Minor adverse reactions include metallic taste, dry mouth sensation and increased thirst, flatulence, fatigue and CNS complaints, including headache, irritability and insomnia. Daily doses of 1 g may cause unconjugated bilirubin levels to double and the reticulocyte count to increase. Hemoglobin concentrations may decrease with treatment or higher dosages; with doses of 3.9–12.6 g per day, a drop in hemoglobin was noted by days 7–13 of treatment, which was generally ‘rapidly’ reversible on withdrawal of the drug, but in some instances necessitated blood transfusion.
Aerosol administration of about 2 g in 36 or 39 h during 3 days is well tolerated, does not affect results of pulmonary function tests, and seems non-toxic.
It is both teratogenic and embryotoxic in laboratory animals, so precautions must be observed in women of childbearing age.
