";s:4:"text";s:5569:" These changes are basically modifications in the concentration of the drugs. Drug-Drug Interaction A change in a drug’s effect on the body when the drug is taken together with a second drug. There are many causes of drug interactions. In this case the increase in active metabolite AIt can often occur that a patient is taking two drugs that are enzymatic inductors, one inductor and the other inhibitor or both inhibitors, which greatly complicates the control of an individual's medication and the avoidance of possible adverse reactions. The following table shows the most common: 2. reciprocal actions or influences among people, such as mother-child, husband-wife, client-nurse, or parent-teacher.

Anytime you take more than one medication, or even mix it with certain foods, beverages, or over-the-counter medicines, you are at risk of a drug interaction. The effects caused by medicinal plants should be considered in the same way as those of medicines as their interaction with the organism gives rise to a pharmacological response. Drug-drug interactions occur when two or more drugs react with each other. The organism has mechanisms to counteract these situations (by, for example, increasing If drug A is metabolized by a cytochrome P450 enzyme and drug B inhibits or decreases the enzyme's activity, then drug A will remain with high levels in the plasma for longer as its inactivation is slower. However, the negative interactions are usually of more interest because of their pathological significance, and also because they are often unexpected, and may even go undiagnosed. For example, one drug may alter the The risk of a drug-drug interaction increases with the number of drugs used.When two drugs are used together, their effects can be additive (the result is what you expect when you add together the effect of each drug taken independently), Both synergy and antagonism can occur during different phases of the interaction between a drug, and an organism. If a drug is present in the digestive tract's absorption zone for less time its blood concentration will decrease. As a result, enzymatic inhibition will cause an increase in the drug's effect. A drug-drug interaction can delay, decrease, or enhance absorption of either drug. As in the previous case, it is possible to find paradoxical situations where an active metabolite causes the drug's effect. Avoid these practices. Taking a medication that was prescribed for someone else or bought off of the Internet can be dangerous, too and lead to unexpected drug interactions. Some drugs, such as the prokinetic agents increase the speed with which a substance passes through the intestines. In these cases the drug that arrives first binds with the plasma protein, leaving the other drug dissolved in the plasma, which modifies its concentration. By studying the conditions that favor the appearance of interactions, it should be possible to prevent them, or at least diagnose them in time. Look up a drug to see which other drugs it interacts with and how serious those interactions are. As a result, enzymatic induction will cause a decrease in the drug's effect. The mechanisms underlying most herb-drug interactions are not fully understood.It is possible to take advantage of positive drug interactions. , drug-drug interaction The combined effect of drugs taken concurrently.
Although the number of potential interacting drug combinations is very large only a small number are relevant in clinical practice. This can cause a wide range of adverse reactions. The result may be antagonism or synergism and may be lethal in some cases. Modifications in the effect of a drug are caused by differences in the absorption, transport, distribution, metabolism or excretion of one or both of the drugs compared with the expected behavior of each drug when taken individually. It is possible that this can occasionally lead to a paradoxical situation, where the enzymatic inhibition causes a decrease in the drug's effect: if the metabolism of drug A gives rise to product AIf drug A is metabolized by a cytochrome P450 enzyme and drug B induces or increases the enzyme's activity, then blood plasma concentrations of drug A will quickly fall as its inactivation will take place more rapidly. They are usually included in the category of foods as they are usually taken as a tea or food supplement.
