Levophed Dopamine Dobutamine
Receptors: These three medications are used to support the heart and cardiovascular system ie. blood pressure and heart rate. They are known as sympathomimetics and have a similar response to what you would think of as adrenaline. Each has variable effect on either heart rate, heart function (in terms of strength of 'squeeze') and on blood vessels which would translate to higher blood pressure. ...Read more
I was wondering what are the differences of levophed, dopamine and dobutamine in terms of their action?
You Asked for It----: Dobutamine- direct b1 receptor stimulant or agonist in the sympathetic nervous system. Levophed- vasoconstrictor peripherally (alpha adrenergic effects) and beta adrenergic stimulant at the level of the heart and coronary vessels dopamine- dual b1 and Alpha adrenergic effects. Useful in hypovolemic shock because of conservancy of renal blood flow. Also, works centrally in other complex ways. ...Read more

Pleasurable: Pleasurable activities, foods, exercises, images, drinks (careful, i don t mean necessarily "those"...), even sex. Those things you enjoy the most, increase your dopaminergic activity. Wherever your passion is, like my brother says. That is in general. Now, in presence of a disease (like parkinsons), the whole mechanism lacks enough neurotransmitter to make this ideas effective.
