Even the bra industry has admitted that a bra will NOT keep breasts from sagging, and that it will only hold them into a position that a particular bra design is designed to do, while the bra is being worn, and when the bra is removed, the breasts will no longer retain that position.
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).
There might also be similar drugs which worked the exact same way, binding to the same receptor. The only ways in which these drugs could differ from the practical point of view are in pharmacokinetics (how fast each drug enters and clears the body) and how potent each drug is. The latter term is one that may easily be misunderstood due to common usage differing from scientific usage.
