Uncertainty about usefulness of antiviral drugs in Ramsay Hunt syndrome


By ncbi.nlm.nih.gov

It seems logical that antiviral drugs might help patients with a herpes virus infection of the ear producing facial weakness (a condition known as 'Ramsay Hunt syndrome'). These drugs often help similar viral infections elsewhere in the body. However, trials that might address this issue have not been done and there is therefore some uncertainty about their usefulness. Since patients can experience side-effects when taking these drugs, the risks of these have to be balanced with the unknown prospect of benefit when considering whether to use them in Ramsay Hunt syndrome.

Background: Herpes zoster oticus (HZO) is a viral infection of the ear and when associated with acute facial paralysis is known as Ramsay Hunt syndrome. Antiviral agents are the standard first-line treatment for herpes zoster infections at other body sites and are thought to reduce or minimise nerve damage, thereby improving outcomes. It has been suggested that these agents improve the chance of facial weakness improving or resolving completely in patients with Ramsay Hunt syndrome.

Objectives: To determine the effectiveness of antiviral agents in the treatment of adult patients with Ramsay Hunt syndrome (HZO with facial palsy).

Search methods: We searched the Cochrane ENT Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, current issue), Medline (1950 - 2007), PubMed 2007 - 2008, EMBASE (1974 onwards) and other relevant databases. The date of the most recent search was June 2008.

Selection criteria: Two authors scrutinized all possible citations to identify randomised controlled trials in which antiviral agents alone or in combination with other therapies (using different routes of administration and dosage schemes) were given as treatment for Ramsay Hunt syndrome. We contacted an author for further information.

Data collection and analysis: Two reviewers independently assessed eligibility and trial quality.

Main results: Only one randomised, controlled trial was identified and included. It was of low quality and included only 15 participants. In this 1992 trial, intravenous acyclovir and corticosteroids were compared with corticosteroids alone. Our analysis found no statistically significant difference between the two groups.

Authors' conclusions: We found no evidence that anti-viral agents have a beneficial effect on outcomes in Ramsay Hunt syndrome, despite their widespread use in this condition. The use of these drugs in patients with herpes zoster infections in other parts of the body might suggest that they have a role in herpes zoster oticus. As usual, the absence of positive evidence of benefit (or, in this case, the 'negative' result of one small, statistically under-powered study) does not necessarily indicate that antivirals are ineffective. However, these drugs are associated with a number of adverse effects and this must be taken into consideration when undertaking the requisite risk-benefit analysis before instigating treatment.

Ropinirole: The Generic Form Of Requip Explained

Ropinirole is the generic name of the medication sold under the brand name Requip. Generic medications contain the same active ingredient at the same dose and strength as their brand name counterparts and must meet the same FDA standards for quality, purity, and bioequivalence. The development and approval of generic drugs play an important role in making effective treatments more accessible and affordable for patients. Allergy treatment has advanced considerably over the past several decades. Early antihistamines were effective but caused significant drowsiness. Modern second-generation antihistamines provide comparable or superior symptom control without the sedating side effects that limited their predecessors. Other treatment modalities include nasal corticosteroid sprays, which reduce airway inflammation, and allergen immunotherapy, which gradually desensitizes the immune system through controlled exposure to specific allergens over time. The pharmacological action of ropinirole is the basis for its use in treating conditions within the category of parkinsons disease. Understanding the mechanism by which the active compound produces its therapeutic effects helps patients appreciate why the medication needs to be taken consistently and at the correct dose to achieve the best results. Switching between brand name and generic versions of a medication is generally considered safe when the products are bioequivalent, but patients should inform their doctor if they notice any differences in effect after a formulary change. Some patients with conditions requiring precise drug levels in the blood may be monitored more closely during transitions. For most patients, however, approved generics provide equivalent therapeutic benefit to the brand name product. The parkinsons disease section on parkinsons disease covers both brand name and generic treatment options, giving patients a complete picture of what is available. Cost, insurance coverage, and pharmacy availability are practical factors to discuss with a pharmacist when filling a prescription for ropinirole.
