This is considered significantly smaller than a ânormalâ male newbornâs penis, which is between 1.1 and 1.6 inches in length when stretched gently.
A drug interaction is a situation in which a substance (usually another drug) affects the activity of a drug when both are administered together.he opposite effect to synergy is termed antagonism. Two drugs are antagonistic when their interaction causes a decrease in the effects of one or both of the drugs. Both synergy and antagonism can both occur during different phases of the interaction of a drug with an organism, with each effect having a different name.
Abstract. Drugs may interact with other drugs or any diet or dietary supplement taken at the same time. Interactions may be pharmacodynamic in which interaction is close to the target organ and involves direct antagonism or addition of pharmacological properties.rug interactions are usually described as pharmacodynamic (where changes in drug action occur in the area of the target tissue) or pharmacokinetic (when one drug affects the absorption, distribution or excretion of another).
