Common Medications That Can Trigger Malignant Hyperthermia
Malignant Hyperthermia (MH) is a serious reaction to some drugs used in anesthesia. It’s important to know which drugs can cause MH to avoid it. Here are the main drugs linked to MH and how they affect people.
Anesthetic Agents
Some anesthetic drugs can cause MH. These drugs work with muscle cells, causing a hypermetabolic state in those at risk. Sevoflurane, desflurane, and isoflurane are known to trigger MH. Doctors must be careful when choosing anesthesia for patients at risk.
Muscle Relaxants
Muscle relaxants can also lead to MH. Succinylcholine is a muscle relaxant that often causes MH. It makes muscles contract a lot, raises calcium in muscles, and leads to a hypermetabolic crisis. To avoid MH, doctors should use other muscle relaxants instead.
Halogenated Inhalational Agents
Drugs like halothane and enflurane can also trigger MH. They release too much calcium in muscle cells, causing high metabolism, heat, and serious problems. It’s key to know these medications that can cause MH and avoid them in treatment.
| Category | Common Triggers |
|---|---|
| Anesthetic Agents | Sevoflurane, Desflurane, Isoflurane |
| Muscle Relaxants | Succinylcholine |
| Halogenated Inhalational Agents | Halothane, Enflurane |
High-Risk Drugs for Malignant Hyperthermia
Malignant hyperthermia (MH) is a serious condition caused by some drugs. It happens more often in people who are genetically at risk. Knowing which drugs are most likely to cause MH is key to avoiding bad reactions.
Succinylcholine
Succinylcholine is a muscle relaxant that’s a big risk for MH. It makes muscles release too much calcium, leading to muscle spasms and high fever. Because of this, doctors avoid using it in people who might get MH.
Desflurane
Desflurane is another drug that can cause MH. It works fast but is risky for people who might get MH. Doctors tell these people to stay away from it.
Isoflurane
Isoflurane is also a high-risk drug for MH. It can cause a big increase in body temperature and muscle stiffness. Researchers and doctors are looking for safer options for people at risk of MH.
| Drug Name | Risk Factor | Mechanism of Action |
|---|---|---|
| Succinylcholine | High | Depolarizing muscle relaxant causing massive calcium release |
| Desflurane | High | Volatile inhalational agent triggering abnormal calcium release |
| Isoflurane | High | Halogenated anesthetic inducing uncontrolled calcium release |
Why Certain Drugs Cause Hyperthermia in Susceptible Individuals
Some drugs can make people get too hot because of their genes. These genes affect how muscles handle calcium. The RYR1 gene is one that can be faulty, leading to problems with calcium.
When people with this issue take certain drugs, like strong anesthetics, it can cause big trouble. These drugs make muscles contract too much and metabolism goes up fast. This can make body temperature rise too high and be very dangerous.
Studies show that some drugs, like strong anesthetics and certain muscle relaxants, can make things worse. They mess with how muscles handle calcium in people who are more sensitive. This can lead to getting too hot.
A study by the Malignant Hyperthermia Association of the United States (MHAUS) looked into this. It found that people with certain gene changes are more at risk. These changes affect how calcium is balanced in muscles.
| Drug Type | Calcium Regulation Effect | Resulting Impact |
|---|---|---|
| Volatile Anesthetics | Increased calcium release | Severe muscle contractions, hyperthermia |
| Depolarizing Muscle Relaxants | Prolonged calcium elevation | Metabolic crisis, elevated body temperature |
