Combination drug therapy as a strategy to improve the efficacy and safety of treatment of herpes simplex virus infections: potential risks and prospects. (PubMed, Vopr Virusol) - "Standard treatment with acyclovir, penciclovir, or the corresponding prodrugs valacyclovir and famciclovir is usually sufficient to stop recurrent HSV infections. When combining drugs that affect the pathogen in different ways, it is important to maintain the therapeutic effect with the use of lower doses due to the synergistic nature of the interaction, which reduces the likelihood of developing unwanted side effects of drugs. The review presents current data on the state and possible prospects for the development of combination therapy for HSV infections, obtained as a result of searching the literature related to anti-herpetical therapy using the PubMed, Medline databases, RSCI, the international registry of clinical trials of the US National Institutes of Health."

Ocular tolerance and tear film pharmacokinetics of 1 % penciclovir cream in cats. (PubMed, Res Vet Sci) - "While oral famciclovir is effective, its use is limited by poor bioavailability and compliance challenges...In the second study, tear fluid samples collected over 24 h revealed that penciclovir concentrations remained above the minimal inhibitory concentration (0.30 μg/ml) for FHV-1 for over 8 h on average, with a terminal half-life of 8.75 h. These findings indicate that Fenlips® is well tolerated and achieves pharmacologically relevant concentrations in the tear film, supporting its potential use as a twice-daily topical treatment for herpetic keratoconjunctivitis in cats."

Ruvidar®-An Effective Anti-Herpes Simplex Virus Agent. (PubMed, Viruses) - "Currently, effective FDA approved anti-herpetic drugs include acyclovir and later-generation derivatives (valacyclovir and famciclovir), which inhibit viral DNA synthesis...In these experiments, we evaluated the ability of Ruvidar® to restrict HSV-1 replication in Vero cells, both by itself and in combination with acyclovir and metformin in the absence of light activation to mimic deep tissue...We also discovered additive and synergistic anti-HSV-1 effects when combinational therapy was tested. Ruvidar® also restricted HSV-1 replication in human U251 glioblastoma astrocytoma cells, remained highly effective against acyclovir-resistant HSV-1 mutants, and protected infected cells from virus-induced cytopathology."

Viral Infections of the Vulva: A Narrative Review. (PubMed, Life (Basel)) - "First-line treatments like oral acyclovir/famciclovir for HSV and topical imiquimod or podophyllotoxin (±cryotherapy) for HPV are supported by adjunctive measures for self-limiting conditions. Personalized, multidisciplinary management that combines prevention, precision diagnostics, tailored therapy, psychosocial support, and economic considerations offers the greatest promise for improving clinical and quality-of-life outcomes in patients with vulvar viral infections. We aim to outline best practices for the diagnosis and management of common vulvar viral infections, providing practical guidance for clinicians to improve recognition and therapeutic decision-making."

Topical and Systemic Therapeutic Approaches in the Treatment of Oral Herpes Simplex Virus Infection: A Systematic Review. (PubMed, Int J Mol Sci) - "Topical treatments, including acyclovir cream, docosanol, and newer formulations, primarily reduce lesion duration and alleviate local symptoms when applied early...Novel delivery methods and combination strategies, such as acyclovir-hydrocortisone formulations or photodynamic therapy, may enhance local efficacy and symptom control. Systemic Therapies: Systemic antivirals, such as acyclovir, valacyclovir, and famciclovir, target both lesion resolution and recurrence prevention...Future research should focus on mechanism-based therapies, novel delivery systems, and standardized outcome measures to guide personalized treatment strategies. Emerging therapies targeting viral latency, immune modulation, and gene-editing technologies hold promise for long-term suppression and personalized management of HSV infections."

Ulcerated Genital Lesions in Pemphigus Vulgaris: Herpes Simplex Virus as a Crucial Differential Diagnosis (ESDR 2025) - "Treatment included prednisone 1 mg/kg/day for pemphigus and initially famciclovir 125 mg twice daily for 10 days for herpes, later changed to acyclovir 400 mg three times daily for 3 weeks due to economic factors and persistence of lesions. Herpes lesions improved within the first week, while pemphigus lesions required prolonged treatment. This case highlights the importance of considering multiple diagnoses in mucosal and genital lesions of patients with immunosuppressed pemphigus, emphasizing that genital ulcerative lesions require a systematic and individualized diagnostic approach due to their diverse potential etiologies."

Recurrent vs. Nonrecurrent Superficial Non-Healing Corneal Ulcers in Cats: A Multifactorial Retrospective Analysis. (PubMed, Animals (Basel)) - "Systemic medications were more often used in recurrent cases, notably oral lysine (47.8% vs. 26.5%; p = 0.049) and famciclovir (17.4% vs. 2.6%; p = 0.016). Recurrent cases also showed significantly higher rates of concurrent viral (p < 0.001) and bacterial/fungal infections (p = 0.027). In conclusion, recurrent superficial non-healing corneal ulcers were associated with age and systemic illness, emphasizing the need for early diagnosis and management of underlying conditions."

When the Lungs Breathe Trouble: Ureaplasma Infection Causing Hyperammonemia Syndrome, Followed by HSV Pneumonitis, After Bilateral Lung Transplant (ISHLT 2025) - "He underwent bilateral lung transplant with induction on basiliximab and methylprednisolone 1 week later, and started on maintenance immunosuppression with corticosteroids, mycophenolate, and tacrolimus...He was initiated on dialysis, lactulose, and rifaximin for HALT, and doxycycline and azithromycin for empiric mollicute coverage; his ammonia subsequently down trended with these interventions...Prophylactic famciclovir was transitioned to acyclovir for fourteen days, with valacyclovir thereafter as alternative viral prophylaxis...Empiric testing of serum ammonia for the week after lung transplant may trigger concern for mollicute infection, which historically carries high mortality after lung transplantation. Meanwhile, while airway wall erythema due to reperfusion injury may be observed soon after transplantation, new sudden onset erythema in subsequent weeks should provoke investigation for infectious causes, particularly HSV pneumonitis."
