Y55: Agents primarily acting on smooth and skeletal muscles and the respiratory system

The group of conditions classified under the title "Agents primarily acting on smooth and skeletal muscles and the respiratory system" refers to various health issues induced by substances that directly impact our body's smooth and skeletal muscles and the respiratory system. These substances can include a wide array of medical or recreational drugs, toxins, and poisons, among other agents. Commonly, these conditions may emerge due to accidental or intentional overexposure to or misuse of such agents. Symptoms can range widely but usually involve muscle pain or weakness, abnormal movements, breathing difficulties, or respiratory distress. These conditions can evolve fairly swiftly or develop over a longer period, depending on the type and quantity of the agent involved and the individual's health status. It is vital to understand that these conditions can affect multiple body systems and can result in severe health complications if not promptly addressed.
