In adults, the condition refers to any penis smaller than 2.8 inches in length. (2) In infants, a Micropenis is classed as any penis that is less than 0.75 inches in length. 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.
The next few slides will focus on drug metabolism. Some important preventable drug interactions are due to their effects on drug metabolizing enzymes, resulting in either inhibition (reduced activity) of the enzyme or induction (increased activity) of the enzyme. There are many potential consequences of changes in drug metabolism for a given drug.
