 Understanding medications and what they do

Sometimes there seems to be more medicine than disease and they can be difficult. Some can be purchased over the counter in pharmacies or other stores. Others require a doctor's prescription. Some are only available in hospitals.

What is medicine?

Medicines are chemicals or compounds used to cure, stop or prevent disease; ease symptoms; or aid in diagnosis. Advances in medicine have enabled doctors to cure many diseases and save lives.

Nowadays, medicines come from different sources. Many were developed from substances found in nature and many are still extracted from plants today.

Some medicines are made by mixing several chemicals in the lab. Others, like penicillin, are biologically engineered by inserting genes into organisms such as fungi and some bacteria that produce their desired substances.

When we think of medication, we often think of pills. But drugs can be delivered in different ways, such as:

No drug can be sold unless approved by the US Food and Drug Administration (FDA). Drug manufacturers conduct tests on all new drugs and send the results to the FDA.

The FDA allows new drugs to be used only if they work and if they are safe enough. When the benefits of a drug outweigh its known risks, the FDA usually approves the drug for sale. The FDA can withdraw a drug from the market at any time if it is found to have harmful side effects.

Different types of drugs

Medicines work in different ways. Some can cure an illness by killing or stopping the spread of invading microbes like bacteria and viruses. Others are used to treat cancer by killing cells because they stop them from dividing or multiplying. Some drugs replace missing substances or correct low levels of natural body chemicals, such as certain hormones or vitamins. Drugs can even affect parts of the nervous system that control body processes.

Almost everyone has taken antibiotics. Such drugs fight against bacterial infections. Your doctor may prescribe an antibiotic for things like strep throat or ear infections. Antibiotics work by either killing bacteria or stopping their multiplication so that the body's immune system can fight the infection.

Sometimes a part of the body can't make enough of the chemical. It can also make you sick. Someone with insulin-dependent diabetes, for example, has a pancreas that can't make enough insulin (a hormone that regulates glucose in the body). Some people have low production of thyroid hormone, which helps regulate how the body uses energy. In each case, doctors can prescribe medications to replace the missing hormone.

Some drugs treat the symptoms but cannot cure the illness causing the symptoms. (A symptom is something you feel when you're sick, like a cough or nausea.) So taking a lozenge might soothe a sore throat, but it won't kill those nasty strep bacteria.

Some medicines relieve pain. If you pull a muscle, your doctor may ask you to take ibuprofen or acetaminophen. These pain relievers, or analgesics, don't get rid of the source of the pain—your muscles will still be pulled. What they do is block the pathways that send pain signals from the injured or irritated body part to the brain (in other words, affect the way the brain reads pain signals) so that you don't hurt as much while your body recovers. .

As people age, they sometimes develop chronic or long-term conditions. Medicines can help control things like high blood pressure (high blood pressure) or high cholesterol. These medications do not cure the underlying problem, but they can help prevent some of its harmful effects on the body over time.

Among the most important drugs are immunizations (or vaccines). They protect the body from getting sick in the first place by immunizing or protecting against certain infectious diseases. Vaccines usually contain small amounts of an agent that resembles a specific germ or germs that have been modified or killed. When someone is vaccinated, it primes the body's immune system to "remember" the germ so that it can fight off future infections with that germ.

Most immunizations that prevent you from catching diseases such as measles, whooping cough and chickenpox are given by injection. No one thinks shots are funny. But the diseases they prevent can be very serious and cause symptoms that last much longer than the temporary discomfort of a shot. To make life easier, you can now get vaccinations at many pharmacies.

Although some drugs require a prescription, some are available over the counter. You can buy many medicines for pain, fever, cough or allergies without a prescription. But just because a drug is available over-the-counter (OTC), doesn't mean it's free of side effects. Take OTC medications with the same precautions as prescribed by a doctor.

take medicine

Regardless of the type of medication your doctor prescribes, it's always important to be safe and follow some basic rules:

Taking medication can seem like a hassle at times. But medicine is the most effective treatment for many ailments. If you have any questions about what a medicine does or how to take it, talk to your doctor or pharmacist.
