Chemistry effect in life


What is chemistry? And how chemistry can effect on drugs?

Certainly chemistry is everywhere that you think, and we have to use it all the time in our daily lives, probably without knowing it. Chemistry in Your Life completed applications sections throughout.


The synthesis of most drugs is accomplished through the procurement of a precursor chemical that requires very little modification to yield the desired product. This is the case with the very popular synthesis of methamphetamine from ephedrine or pseudoephedrine. The nature of this synthesis is relatively simple, and the availability of the direct precursor to the general public in the form of cold/decongestant pills makes it all the more so. However, as a result of the proliferation of methamphetamine labs across the United States, governmental regulations and obliging drug companies have progressively made such pills more difficult to extract. This has resulted in the necessity of formulating more refined and ingenious extraction methodologies, which has actually become quite an art of its own.



Advil





Advil is in a group of drugs that called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing hormones that cause inflammation and pain in the body.

Advil is used to reduce fever and treat pain or inflammation caused by many conditions such as headache, toothache, back pain, arthritis, menstrual cramps, or minor injury.

Advil may also be used for purposes other than those listed in this medication guide.

Some important information about Advil are, increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use Advil. Do not use this medicine just before or after having heart bypass surgery.

This medicine can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking Advil. Older adults may have an even greater risk of these serious gastrointestinal side effects.

Avoid taking Advil if you are taking aspirin to prevent stroke or heart attack. Advil can make aspirin less effective in protecting your heart and blood vessels. If you must use both medications, take the Advil at least 8 hours before or 30 minutes after you take the aspirin. Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to Advil (such as ketoprofen or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen. Do not drink alcohol while taking Advil. Alcohol can increase the risk of stomach bleeding caused by this medicine. Avoid exposure to sunlight or artificial UV rays. Advil can make your skin more sensitive to sunlight and sunburn may result. Use a sunscreen and wear protective clothing if you must be out in the sun.
