Acyclovir and Valaciclovir are two antiviral drugs. Because these two are in the same class, their mechanism of action is similar. Acyclovir Acyclovir is an antiviral drug synthesized using the nucleoside extracted from the sponge Cryptotethya crypta. It is available in the market under many brand names. Acyclovir is a very commonly used drug, and the commonest indication is Herpes viral infections. It may be used in pregnancy if the benefits outweigh the risks only. The mechanism of action of acyclovir is complicated. Once the drug enters the body the viral enzyme called thymidine kinase converts it to acyclovir monophosphate. Then, cellular kinase enzymes convert it into acyclovir triphosphate. This final product blocks DNA replication and viral reproduction. Acyclovir is very effective against many species of herpes virus family, and resistance to the drug action is encountered very rarely. Therefore, if taken in tablet form the amount that reaches the blood is small. Therefore to obtain high concentrations, acyclovir should be given intravenous. Half-life is the time taken to reduce the concentration by half. Both are new antiherpesviral prodrugs (in the same class as acyclovir). Indication: Acute herpes zoster in the immunocompetent host. (Their role in genital herpes will be discussed in a future Therapeutics Letter). Mechanism of Action: Reduce viral replication by inhibiting viral DNA polymerase. Pharmacokinetics: Valacyclovir is a prodrug of, and metabolized to acyclovir; the oral bioavailability of acyclovir from valacyclovir is 54% as compared to 15-30% for acyclovir. Famciclovir is a prodrug for the active metabolite penciclovir; the mean oral bioavailability of penciclovir from famciclovir is 77%. Penciclovir plus acyclovir are primarily eliminated unchanged by the kidneys and have mean half-lives of 2.5 hours.

The use of gabapentin in dogs is primarily to manage chronic nerve pain, with mild effectiveness managing seizures. As with human use, the mechanism that allows the medication to work is not well understood, however, while it is structurally similar to the neurotransmitter GABA, it does not negatively affect its function. That is not to say that there are no negative gabapentin side effects in dogs, but with regular use that is monitored by a veterinarian the benefits of gabapentin for dogs outweigh the risks. Every dog will react differently to the medication and working to find the gabapentin dosage for dogs that are similar to your own with your veterinarian will ensure the best results. Gabapentin in dogs is used in varying doses depending on the severity of the pain that they are experiencing. The medication tends to be more effective when it can be used in conjunction with other types of pain relievers such as NSAIDs. Common disorders that gabapentin dogs receive treatment for include: hyperalagesia, allodynia, chronic arthritis pain, and other nerve pain disorders.
