Clinical Presentation

Overview of Autonomic Nervous System (ANS)

The autonomic nervous system regulates involuntary bodily functions, including heart rate, blood pressure, respiration, digestion, and sexual arousal. It is divided into the sympathetic and parasympathetic nervous systems, which work together to maintain homeostasis.

Underdosing Implications

Underdosing occurs when a patient receives less than the prescribed or required amount of medication. In the context of drugs affecting the ANS, this can lead to a range of clinical manifestations depending on the specific drug involved and the underlying condition being treated.

Signs and Symptoms

Common Symptoms of Underdosing

1. Increased Heart Rate (Tachycardia): Insufficient medication may fail to control heart rate, leading to tachycardia, especially in patients with conditions like hypertension or heart failure.
2. Hypotension: Patients may experience low blood pressure if medications that support vascular tone are underdosed.
3. Dizziness or Lightheadedness: Insufficient autonomic regulation can lead to orthostatic hypotension, causing dizziness upon standing.
4. Fatigue: Patients may report increased fatigue due to inadequate management of their condition.
5. Gastrointestinal Symptoms: Symptoms such as constipation or diarrhea may arise if medications affecting gut motility are underdosed.
6. Sweating Abnormalities: Patients may experience excessive sweating or anhidrosis (lack of sweating) depending on the drug's role in thermoregulation.

Specific Patient Characteristics

• Age: Older adults may be more susceptible to the effects of underdosing due to polypharmacy and altered pharmacokinetics.
