Final answer:
Malignant hyperthermia is an adverse effect to certain drugs, while synergistic interactions enhance drug effects and antagonistic interactions may reduce effectiveness or increase risk of adverse effects. Agonist drugs enhance or mimic neurotransmitter effects.
Step-by-step explanation:
Malignant hyperthermia is an adverse effect to certain drugs. This serious reaction is characterized by the rapid rise in body temperature and severe muscle contractions when the susceptible individuals are exposed to certain general anesthetics or muscle relaxants. Recognizing and treating this condition quickly is crucial to prevent potentially life-threatening complications.
Synergistic drug interactions are those where two or more drugs interact in a way that enhances or improves the therapeutic effect of one or both drugs. On the other hand, antagonistic interactions involve drugs working against each other, which may inhibit their effectiveness or increase the risk of adverse effects. An example of an antagonistic interaction is when antacids affect the absorption of certain antimicrobials, reducing their effectiveness in treating infections.
An agonist drug helps a neurotransmitter system by mimicking or enhancing the effects of the neurotransmitter. For example, a drug that acts as an agonist may bind to the receptors and activate them or it may increase the neurotransmitter levels by preventing their reuptake, leading to prolonged effects.
