The pharmacodynamics is he study of the effect generated by drugs in the organism of people. Also mentioned as pharmacodynamics, investigates the physiological and biochemical consequences that are registered at the organic level by the action of these substances.
Among the objectives of pharmacodynamics is the description of the primary or therapeutic effects of the drug. For example, pharmacodynamics may indicate that a remedy it is antipyretic (if it helps reduce fever) or anti-inflammatory (when it helps to reverse inflammation).
Other useful information provided by pharmacodynamics is linked to the side, collateral or unwanted effects of drugs. These are those referrals that, on occasions, can be detrimental to the Health. The Placebo effectmeanwhile, it occurs when manifestations appear that are not directly associated with the pharmacological action.
The mechanism of action (the way to act) and the activity center (the site where it acts) of the drug are other questions analyzed by pharmacodynamics. It is important to clarify that the reaction caused by the remedy in the body It does not depend exclusively on the characteristics of the drug itself, since various extrinsic factors such as the subject’s genetics, general condition and age influence. In addition, the interactions that occur between different drugs also affect pharmacodynamics.
It is known as pharmacokinetics, on the other hand, to the effects caused by the organism about a drug. Both pharmacodynamics and pharmacokinetics are important for understanding the link established between a dose of the substance and the organic response to it.
