    Azithromycin cyp3a4

    Cytochrome P450 3A4 (abbreviated CYP3A4) (EC 1.) is an important enzyme in the body, mainly found in the liver and in the intestine. It oxidizes small foreign organic molecules (xenobiotics), such as toxins or drugs, so that they can be removed from the body. While many drugs are deactivated by CYP3A4, there are also some drugs which are activated by the enzyme. Some substances, such as grapefruit juice and some drugs, interfere with the action of CYP3A4. These substances will therefore either amplify or weaken the action of those drugs that are modified by CYP3A4. CYP3A4 is a member of the cytochrome P450 family of oxidizing enzymes. Several other members of this family are also involved in drug metabolism, but CYP3A4 is the most common and the most versatile one. Arc Mesa Educators has provided more than 400,000 credit hours and awarded 210,000 certificates to physicians and physician assistants, nurses, radiologic technologists, dentists and dental hygienists, dieticians, funeral directors and many others seeking credits for license renewal. Arc Mesa Educators is accredited by the Many drugs undergo oxidative biotransformation in order to be transformed from lipophilic to hydrophilic compounds so that they may be more readily eliminated from the body. The cytochrome P450 enzyme system is the major catalyst of oxidative biotransformation reactions involved in drug metabolism. The nomenclature of the cytochrome P450 enzyme system involves grouping the enzymes into families and subfamilies. Of the different isoforms of cytochrome P450, CYP3A4 is the most prevalent in humans and is the most important form of the enzyme in terms of drug metabolism. The cytochrome P450 enzyme system plays a significant role in drug metabolism, particularly with regard to drug interactions. Many drug interactions are a result of inhibition or induction of the cytochrome P450 enzymes.

    Aug 2, 2013. The study by Patel et al demonstrates that choosing to use an antibiotic that does not inhibit CYP3A4 eg, azithromycin is a simple way to avoid. For example, within the macrolide antibiotics, all of them are known inhibitors of CYP3A4 with the exception of azithromycin. For the calcium channel blockers. Due to its structural differences, azithromycin does not interact with CYP3A4, SLCO1B1 or SLCO1B3, and therefore has a longer half-life and fewer drug.

Мы живем в эру полипрагмазии, так что, сейчас нередко можно встретить пациента с каким-то хроническим заболеванием, который принимает полдюжины разных лекарств, или даже больше. Поскольку мы используем больше лекарств, и больше комбинаций разных лекарственных препаратов, чем когда-либо ранее, частота лекарственных взаимодействий в наше время сильно увеличилась. Лекарственные взаимодействия могут снижать эффективность одного или более препаратов в комбинации, или приводить к другим нежелательным эффектам. Лекарственные взаимодействия также рассматриваются как ошибки, которые потенциально можно предотвратить. С появлением электронной медицинской документации и электронных назначений все стали возлагать надежды на программное обеспечение, которое должно предупреждать делающего назначение врача о возможности взаимодействия с одним или более из принимаемых пациентом лекарств, и эти оповещения действительно достаточно часто встречаются. На самом деле, они настолько вездесущи, что в процессе назначения их часто игнорируют, так что в результате оказывается, что нельзя рассчитывать, на предотвращение всех взаимодействий электронной системой оповещений. Ниже приведены примеры частых лекарственных взаимодействий и предлагаемые способы их профилактики от профессора Douglas S.
