In our daily lives, we are often faced with health problems and dilemmas in drug choice. Among the many medicines, some are widely recommended and used, while others are less well known. Puzzledly, overlooked drugs are often affordable and effective, but often go unnoticed on the shelves of pharmacies. 
Why is this happening? Is it because these drugs lack effectiveness, or is it simply because they are inexpensive? Or, do pharmacies have other recommendations? These questions have piqued curiosity about the deeper reasons behind the choice of drugs. 
In daily life, there are some drugs that, although not high, play an important role in the maintenance of health. These drugs are often not advertised or recommended by pharmacy staff, but their effectiveness in preventing and ailmenting common ailments should not be underestimated. For example, for mild pain and fever, common nonsteroidal anti-inflammatory drugs (such as ibuprofen) can provide effective relief. These drugs are less costly, but they are not inferior to more expensive alternatives in terms of relieving mild pain, reducing fever, etc. Similarly, for minor indigestion or excess stomach acid, common antacids and sodium bicarbonate preparations can provide immediate relief, and these medications are also relatively low in pharmacies. In common respiratory ailments, such as common coughs and colds, simple medications such as honey lemonade or glycerin sulfonamide cough drops often provide immediate relief at a relatively low cost. Their effectiveness is widely recognized in everyday life, but they are often not the preferred recommendation in pharmacies. The existence of these "guardians" reminds us that when choosing a drug, we should not be just swayed by the ** or the brand. Effective medications don't have to be expensive, and these affordable options are just as trustworthy for everyday ailments. 
*Loading....When it comes to drug selection, ** and effect are often seen as two interrelated factors. Many people believe that drugs with high ** are more effective. However, this is not always the case. Many affordable drugs are not inferior to ** drugs in terms of effectiveness. For example, basic medications for high systemic arterial blood pressure, such as amlodipine or diuretics, are inexpensive but highly effective in controlling blood pressure. The cost-effectiveness of these drugs has been confirmed in multiple studies, and there is no significant gap in their role in preventing cardiovascular events compared to newer and more expensive drugs. Similarly, in the management of glucose metabolism abnormalities, some traditional drugs such as metformin, which are less costly but are very effective in controlling blood glucose levels. These drugs have been clinically used and researched for a long time, and their safety and efficacy have been widely recognized. 
*Loading....In pharmacies, there are often drugs that become "unpopular" because they are not the focus of big brands or advertising. These drugs are often overlooked because they are cheap, but in specific cases, their effects are very significant. For example, for minor burns or cuts, a basic silver sulfonamide cream is an economical and effective option. Although it is not as well known as some newer topicals, it is highly effective in promoting wound healing. On the other hand, for **ordinary** fungal infections, drugs like clotrimazole, although not high, are comparable in effectiveness to more expensive drugs. The reason why these drugs are not often recommended in pharmacies may be related to the profit structure and marketing strategy of the pharmacy. However, as consumers and patients, it is important to understand these "unpopular" but cost-effective drugs to make more informed drug choices. These drugs can serve as an effective and economical option when faced with health problems. 
*Loading....Smart medicine is not only about choosing the right medicine, but also about a process that combines knowledge and practice. Understanding and utilizing those affordable and effective medicines is important for maintaining one's health. First of all, understanding common diseases and corresponding drug choices is fundamental. For example, for common headaches, muscle aches, or minor colds, knowing which over-the-counter medications, such as acetaminophen or ibuprofen, are safe and effective to use is important for self-management. Secondly, the right way to take medication is also crucial. This includes knowing the correct dosage of the drug, when, and possibly*** For example, in patients with dybetic metabolism, proper use of metformin or other hypoglycemic drugs, following doctor's instructions, and avoiding inappropriate dose adjustments are essential for glycemic control. In addition, smart medication also means seeking professional advice when necessary. While many medications can be purchased without a doctor's prescription, it is important to be aware of an individual's health status and any potential health risks before using any medication.
