  • CYP3A4 Mediated Pharmacokinetics Drug Interaction Potential of Maha
    www.nature.com/scientificreports OPEN CYP3A4 mediated pharmacokinetics drug interaction potential of Maha‑Yogaraj Gugglu and E, Z guggulsterone Sarvesh Sabarathinam1, Satish Kumar Rajappan Chandra2 & Vijayakumar Thangavel Mahalingam1* Maha yogaraja guggulu (MYG) is a classical herbomineral polyherbal formulation being widely used since centuries. The aim of this study was to investigate the efect of MYG formulation and its major constituents E & Z guggulsterone on CYP3A4 mediated metabolism. In vitro inhibition of MYG and Guggulsterone isomers on CYP3A4 was evaluated by high throughput fuorometric assay. Eighteen Adult male Sprague–Dawley rats (200 ± 25 g body weight) were randomly divided into three groups. Group A, Group B and Group C were treated with placebo, MYG and Standard E & Z guggulsterone for 14 days respectively by oral route. On 15th day, midazolam (5 mg/kg) was administered orally to all rats in each group. Blood samples (0.3 mL) were collected from the retro orbital vein at 0.25, 0.5, 0.75, 1, 2, 4, 6, 12 and 24 h of each rat were collected. The fndings from the in vitro & in vivo study proposed that the MYG tablets and its guggulsterone isomers have drug interaction potential when consumed along with conventional drugs which are CYP3A4 substrates. In vivo pharmacokinetic drug interaction study of midazolam pointed out that the MYG tablets and guggulsterone isomers showed an inhibitory activity towards CYP3A4 which may have leads to clinically signifcant interactions. Te use of alternative medicine such as herbal medicines, phytonutrients, ayurvedic products and nutraceuticals used widely by the majority of the patients for their primary healthcare needs.

  • Drug Interactions: What You Should Know
    DRUG INTERACTIONS: WHAT YOU SHOULD KNOW Council on Family Health Drug Interactions here are more opportunities today than ever before to learn about your health and to take Tbetter care of yourself. It is also more important than ever to know about the medicines you take. If you take several different medicines, see more than one doctor or have certain health conditions, you and your doctors need to be aware of all the medicines you take to avoid potential problems, such as drug interactions. Drug interactions may make your drug less effec- tive, cause unexpected side effects or increase the action of a particular drug. Some drug interactions can even be harmful to you. Reading the label every time you use a nonprescription or prescription drug and taking the time to learn about drug interactions may be critical to your health. You can reduce the risk of potentially harmful drug interactions and side effects with a little bit of knowledge and common sense. Drug interactions fall into three broad categories: ■ Drug-drug interactions occur when two or more drugs react with each other. This drug- drug interaction may cause you to experience an unexpected side effect. For example, mixing a drug you take to help you sleep (a sedative) and a drug you take for allergies (an antihistamine) can slow your reactions and make driving a car or operating machinery dangerous. ■ Drug-food/beverage interactions result from drugs reacting with foods or beverages. For example, mixing alcohol with some drugs may cause you to feel tired or slow your reactions.

Objectives: The objectives were to assess potential interactions between digoxin and other medications and to evaluate its degree, clinical outcomes as well as identify patients that may require constant monitoring and vigilance. Methods: The cross- sectional and prospective study involves the evaluation of digoxin interaction with other medications using online drug interaction software checkers developed by Medscape.com, Drug.com, Drugbank.com and Epocrates.
