Haloperidol, a conventional antipsychotic, was mixed with piperine in a ketamine-induced schizophrenia rat model to evaluate the interaction potential of this mixture through in-vitro and in-vivo analyses. Piperine, known for its CYP450 enzyme inhibitory effects, enhances the bioavailability of various drugs. Initial in-vitro assays using a high-throughput fluorometric method showed that the haloperidol-piperine mixture inhibited CYP3A4 and CYP2D6 enzymes, comparable to positive controls.

  • Acute encephalitis syndrome (AES) is a significant health issue in India, primarily caused by the Japanese Encephalitis (JE) virus, particularly affecting children under 15, despite vaccination efforts.
  • A study involving 266 children in Uttar Pradesh assessed the immune response to the SA-14-14-2 JE vaccine, finding that a majority (97.74%) had no detectable anti-JEV-specific IgG antibodies after two doses.
  • Results indicated a declining trend in antibody levels over time, highlighting the need for booster doses to maintain immunity against the JE virus in vaccinated children.

Background: In healthy volunteers, the probe drug method is widely practised to assess the pharmacokinetic mediated herb-drug interactions (HDI). We analyzed the clinical evidence of CYP3 A4 probe drug, Midazolam.

Methods: Literatures, where Midazolam was used as a probe drug for prediction of herb-drug interaction, were surveyed through an online database such as google scholar, Scopus, Cochrane, PubMed and clinicaltrials.

Objective: To analyze the safety and efficacy of certain biologics DMARDs (Adalimumab, Baricitinib, Pefacitinib and Sirukumab) either used alone or as a combination with MTX for management of rheumatoid arthritis.

Method: We conducted a systematic literature review on various phase 3 Randomized controlled trails, double blind, placebo controlled, parallel group clinical trials for 52 weeks from 2017 to 2019 conforming to the Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines. The primary efficacy endpoints were American College of Rheumatology 20 response rate improvement criteria, other secondary endpoints were American College of Rheumatology 50/70 response rates, Health Assessment Questionnaire Disability Index, Disease Activity Score-28 for rheumatoid arthritis with Erythrocyte Sedimentation Rate/C Reactive Protein and Radiographic outcomes.

Background: CYP450 enzymes in the liver have a significant role in the metabolism of xenobiotics. Probe drug strategy is broadly used to evaluate the pharmacodynamic and pharmacokinetic drug/ herb-drug interactions/ food-drug interactions. Probe drugs reveal the exact pathway of drug metabolism in the liver by their targeted tractability property.

Purpose: Type 2 diabetes mellitus (T2DM) is a multifactorial disease characterized by insulin resistance. As time progresses, monotherapy often does not provide effective glycemic control, generating the need for an add-on therapy. Hence, multiple oral hypoglycemic agents formulated as a single-dose form called fixed-dose combinations (FDCs) play an essential role in glycemic control.
