Drug interactions are a complex issue that involves many factors, including the type of drug, dosage, the patient's physical condition, and so on. Some drug combinations may enhance the therapeutic effect, while others may increase side effects or cause danger. The following are some examples of common drug-enhancing interactions, but be sure to use any drug combination under the guidance of a doctor or pharmacist: 1. **Antibiotics and probiotics**: Certain probiotics combined with specific antibiotics can help reduce the intestinal flora imbalance caused by antibiotics. 2. **Cocktail therapy in AIDS treatment**: This type of therapy often combines multiple antiretroviral drugs to improve viral suppression. 3. **Levodopa and Carbidopa**: Used to treat Parkinson's disease, these two drugs can be used together to improve efficacy and reduce side effects. 4. **Antidepressants and antianxiety drugs**: Some antidepressants can be combined with antianxiety drugs (such as benzodiazepines) to enhance the effect, but they need to be used with caution to avoid dependence. 5. **Aspirin and clopidogrel**: In the prevention of cardiovascular and cerebrovascular events, the combination of these two drugs can enhance the antiplatelet effect, but may increase the risk of bleeding. It should be noted that the mixing of drugs must be carried out under the guidance of professional medical personnel to ensure safety and effectiveness. Mixing drugs without professional guidance may cause serious health risks.
