It can appear that there are more drugs than there are illnesses at times, and it can be difficult to keep track of all of the different types. Some are available over-the-counter at pharmacies and other retail establishments. Others necessitate the use of a doctor’s prescription. Some are only available in hospitals, while others are available anywhere.
What Are Medicines?
Medicine is a substance or combination of substances that are used to treat, slow, or prevent disease; alleviate symptoms or aid in the diagnosis of illnesses. Doctors have been able to treat numerous ailments and save many lives as a result of medical advancements.
In today’s world, medicines can be obtained from a multitude of sources. Many were originated from compounds found in nature, and many are still produced today using plant-based extracts.
Some medicines are created in laboratories by combining a number of different substances. Others, such as penicillin, are produced as byproducts of organisms such as fungi. And a handful of them has even been biologically created, with genes being inserted into bacteria that cause them to generate the desired compound.
In order to become a pharmacist or to manufacture one’s own medications, one must first obtain the necessary certificates from the appropriate university. Please visit the pharmacy university in Malaysia for additional information.
Different Types of Medicine
Medicines have a variety of effects on the body. It is possible to heal an illness by destroying or slowing the transmission of invading microorganisms, including pathogens such as bacteria and viruses. Cancer is treated with other drugs that work by either destroying cancer cells as they divide or preventing them from proliferating. Some medications are used to replace missing ingredients or to correct low levels of natural body chemicals, such as hormones or vitamins, in the body. Medicines can even have an effect on portions of the nervous system that are in charge of controlling bodily function.
Antibiotics have been taken by nearly everyone. This sort of medication is used to combat bacterial infections. For conditions such as strep throat or an ear infection, your doctor may recommend that you take an antibiotic. Antibiotics operate by either killing bacteria or preventing them from reproducing, allowing the body’s immune system to fight off the illness and heal itself.
Sometimes a chemical cannot be produced by a certain portion of the body. That has the potential to make you sick as well. In the case of insulin-dependent diabetes, for example, the patient’s pancreas is unable to make sufficient insulin (a hormone that regulates glucose in the body). Some people have decreased thyroid hormone production, which affects how the body uses energy and can cause weight gain. In any of these situations, doctors can prescribe medications to replenish the hormone that has been depleted.
Some medications can alleviate symptoms but are unable to heal the underlying ailment that is causing them. Symptoms (which include things like cough and nausea) are whatever you experience while you are sick. So while swallowing a lozenge may provide temporary relief from a sore throat, it will not eliminate the nefarious strep germs.
