Vidarabine (IPA: vaɪˈdærəˌbaɪn) is an antiviral drug used in the treatment of herpes simplex and varicella zoster viruses. The spelling of Vidarabine is derived from its chemical structure, which includes a purine nucleoside called adenine. The -arabine suffix is commonly used in the naming of nucleoside analogs, indicating that the drug is a modified version of adenosine. The correct pronunciation of Vidarabine includes the stress on the second syllable and a prominent long "i" sound in the second and fourth syllables.
Vidarabine is a noun that refers to a synthetic antiviral medication used for the treatment of viral eye infections, particularly those caused by the herpes simplex virus. It is primarily available in the form of an ointment or cream that is applied topically to the affected area.
Vidarabine belongs to the purine nucleoside analogues class of drugs. As an analog of adenosine, it works by inhibiting the replication of the viral DNA, thereby preventing the virus from spreading and multiplying further. By inhibiting viral replication, vidarabine helps in reducing the severity and duration of viral eye infections.
This antiviral agent is specifically indicated for the treatment of herpetic keratitis, which is a viral eye infection affecting the cornea. It may also be used for other ocular viral infections under the supervision of a qualified healthcare professional.
As with any medication, there can be potential side effects associated with the use of vidarabine. Some common side effects may include mild burning or stinging sensations upon application, temporary blurred vision, irritation or redness of the eye, and allergic reactions such as itching or swelling. If any severe side effects or adverse reactions are experienced, immediate medical attention should be sought.
In conclusion, vidarabine is an antiviral medication used for the treatment of viral eye infections, particularly herpetic keratitis. It works by inhibiting the replication of viral DNA and reducing the severity and duration of the infection.
The word "Vidarabine" is derived from the combination of two components: "Vidar-" and "-abine".
- "Vidar" comes from "Vidarik" or "Vidarr", which is a figure in Norse mythology. Vidar is known as the son of Odin and the giantess Grid. He is depicted as a silent and powerful god who avenges the death of his father during the Ragnarok, the end of the world in Norse mythology. The exact reason behind the choice of this name for the drug is unclear.
-"-abine" is a common suffix used in pharmacology to indicate a nucleoside analogue or derivative. Many antiviral drugs end with this suffix, such as "Ribavirin" and "Lamivudine". The suffix "-abine" suggests that Vidarabine is a modified or synthetic nucleoside.
