1. Assignment 2.This chapter contains information on over 30 different ophthalmic drugs (dispersed throughout the chapter). To help you learn these agents, use your word processor to prepare a table listing/comparing each drug and its indications. You can use the following format:

Brand Name

Therapeutic Category

Mechanism of Action

Specific Uses in Surgical Patient

Fill in the indicated information for each drug. For information on specific uses, talk to the medical and nursing staffs at your practice site and identify specific uses of the drug in the patients they see and care for. For example, what procedures are performed at your practice site in which sodium hyaluronate is used? Recognize that some drugs may not be used by your medical staff. For those of you who do not currently work in an OR setting, see what information you can find about the specific uses of each product from information on the web. Use some of the drug information sites provided in other lessons, such as:

• http://www.drugs.com
• http://www.pdrhealth.com/drug_info/index.html
• http://www.rxlist.com
• http://www.nlm.nih.gov/medlineplus/druginformation.htm

An alternative is to perform a search by drug name in Google or another search engine.

When your table is complete, save the document as an .rtf file. Please save your file using the following naming convention: LastNameFirstInitial-Lesson10-DrugTable.rtf.
