When you hear lopinavir ritonavir, a fixed-dose combination antiretroviral drug used to treat HIV infection. Also known as Kaletra, it's not just another pill—it's a backbone treatment for many people living with HIV. This combo works because lopinavir blocks a key enzyme HIV needs to copy itself, while ritonavir boosts lopinavir’s effect by slowing down how fast your body breaks it down. Together, they keep the virus in check, reduce viral load, and help preserve immune function.
This pair is part of a larger group called protease inhibitors, a class of HIV drugs that target the virus’s ability to mature and become infectious. Unlike some newer HIV meds that require just one pill a day, lopinavir ritonavir often comes in capsules or tablets taken twice daily, sometimes with food to improve absorption. It’s not usually the first choice for beginners anymore—newer drugs have fewer side effects—but it’s still widely used in resource-limited settings, for children, or when other treatments fail. People who’ve been on HIV meds for years might still rely on it because it’s proven, reliable, and often cheaper than newer options.
It’s not without trade-offs. Common side effects include nausea, diarrhea, and headaches. Long-term use can raise cholesterol and triglycerides, which is why doctors monitor blood work regularly. It also interacts with a lot of other drugs—like statins, sedatives, and even some herbal supplements—so it’s critical to tell your provider everything you’re taking. If you’re on this combo, you’re not just managing HIV; you’re managing a complex drug system that requires attention to timing, diet, and other medications.
