Help me pls!!!

metformin (glucophage) is an oral antidiabetic that belongs to the chemical class of biguanides. it inhibits hepatic glucose production and increases sensitivity of peripheral tissue to insulin. you might want to do a little studying on insulin resistance since this is what the oral diabetic medications are commonly prescribed for.

terbutaline sulfate is a selective beta agonist and mostly used as a bronchodilator. it is chemically classified as a catecholamine. it relaxes bronchial smooth muscle by acting on the beta-2 adrenergic receptors resulting in bronchodilation, diuresis, central nervous system stimulation, cardiac stimulation, and relaxation of the smooth muscles of the uterus. it is used for bronchospasm and has been more recently investigated in the use of premature labor.

here are some links that will give you information about these drugs, how they work as well as some of the nursing implications in the use of them. hope this gives you enough information for your test! you are most likely going to be asked what the side effects of these drugs are. metformin, in particular, has some side effects that are quite well known that sometimes result in the drug having to be discontinued. i'm not quite sure about the side effects of terbutaline, but i do know that i have mostly seen it given subcutaneously or iv which makes it unavailable for most home use. in doing some of the searching for information for you i saw that there were other oral preparations of beta-2 adrenergic receptors, both long and short acting, that were more commonly ordered for home use. good luck on your test!

http://www.pharmacology2000.com/diabetes/physio1.htm - there is information about biguanides, and specifically metformin, on this pharmacology school page near the bottom (use your "find" function on the edit menu of your tool bar to get to it faster). it gives you all the basics that you will need to know about this drug that distinguishes it from others along with it's side effects.

http://www.globalrph.com/diabetes.htm - information on metformin

http://www.drugguide.com/classification_articles/antidiabetics.htm - has nursing implications for patients on antidiabetic medications. information about metformin is scattered thoughout this page.

http://www.pharmacology2000.com/autonomics/adrenergics/adren1.htm - you will find information about terbutaline on this page. it is a smooth muscle relaxant, a catecholamine. it's use in respiratory problems is about 2/3 down this webpage.

http://www.drugguide.com/classification_articles/bronchodilators.htm - information about bronchodilators, including some specific information about how the beta-adrenergic agonists work. includes nursing implications.

thanks for the reply.it really hepls...
