Objective: To determine plasma pharmacokinetics of penciclovir following oral and rectal administration of famciclovir to young Asian elephants (Elephas maximus). Animals: 6 healthy Asian elephants (5 females and 1 male), 4.5 to 9 years old and weighing 1,646 to 2,438 kg. Procedures: Famciclovir was administered orally or rectally in accordance with an incomplete crossover design. Three treatment groups, each comprising 4 elephants, received single doses of famciclovir (5 mg/kg, PO, or 5 or 15 mg/kg, rectally); there was a minimum 12-week washout period between subsequent famciclovir administrations. Serial blood samples were collected after each administration. Samples were analyzed for famciclovir and penciclovir with a validated liquid chromatography–mass spectroscopy assay. Results: Famciclovir was tolerated well for both routes of administration and underwent complete biotransformation to the active metabolite, penciclovir. Mean maximum plasma concentration of penciclovir was 1.3 μg/mL at 1.1 hours after oral administration of 5 mg/kg. Similar results were detected after rectal administration of 5 mg/kg. Mean maximum plasma concentration was 3.6 μg/mL at 0.66 hours after rectal administration of 15 mg/kg; this concentration was similar to results reported for humans receiving 7 mg/kg orally. Conclusions and Clinical Relevance: Juvenile Asian elephants are susceptible to elephant endotheliotropic herpesvirus. Although most infections are fatal, case reports indicate administration of famciclovir has been associated with survival of 3 elephants. In Asian elephants, a dose of 8 to 15 mg of famciclovir/kg given orally or rectally at least every 8 hours may result in penciclovir concentrations that are considered therapeutic in humans.

Corona Discharge Therapy,an evidence-based therapeutic modality, was used on a 40-year-old female Malaysian elephant. The elephant was on systemic therapy for her wounds for 5 days. All therapies were then stopped for 4 days. Corona Discharge Therapy was subsequently applied on both the hind limb joints for 3 sessions. The non-invasive
treatment was made with a multi-patented, electronic therapeutic device called VET Sonotron without the concurrent use of drugs. Corona discharge beam (CDB) of the device was used to relieve the joint pain and inflammation. The skin surface of the elephant joints was scanned with the CDB emanating from a discharge electrode to
which was applied periodic bursts of radio frequency at 0.43 mHz, pulsed at 1 kHz of sound frequency. This therapy showed remarkable anti-inflammatory effects.

Regional perfusion with Triple sulpha was used to treat a severe abscess in a 7-year old female Asian elephant (Elephas maximus) housed at a temple in Tamil Nadu, India. The cow elephant was presented with an acute swelling at left shoulder that persisted despite 4 days of anti-inflammatory therapy. There was a 3-cm-deep, 5-cm-diameter abscess pocket that was subsequently debrided. Regional perfusion was performed by using 7% Tincture iodine for 15 days, and Triple sulpha in the wound pocket. Besides, the elephant received Enrofloxacin (dosed at 10 mg/kg b.wt.) and Meloxicam (dosed at 0.2 mg/kg b.wt.) intramuscularly. Within 2 days of administering the first perfusion, the swelling reduced dramatically. After 7 days of successive treatment, the elephant showed marked improvement. The affected skin area became normal after 60 days post-treatment.
