Pharmacokinetics refers to the absorption, distribution, metabolism, and excretion (ADME) of drugs within the body. With aging, various physiological changes occur that significantly impact these pharmacokinetic processes, which are particularly important in clinical geriatrics when prescribing medications to older adults.

Absorption: Aging can influence drug absorption, although the overall effect is often modest. One of the main changes in the gastrointestinal (GI) system is a reduction in gastric acid production, which may affect the solubility and, therefore, the absorption of certain drugs. The delayed gastric emptying time and decreased splanchnic blood flow in the elderly can also result in slower drug absorption.

Achalasia cardia

A 71-year-old female with longstanding history of episodic non-bilious projectile vomiting (mostly undigested food and saliva) presented with worsening of her symptoms and food intolerance during the previous six months. Over that time frame, she noted a sensation of food becoming stuck in her throat and progressive difficulty swallowing. This difficulty was initially related to solids and then progressively to liquids, which severely limited her food intake. She lost 8 kg since the symptoms started to worsen. She stays alone and does not smoke or drink alcohol. Her family history is non-contributory. Evaluation of her upper Gl endoscopy showed dilated esophagus and pooling of saliva and a tight GE junction. The barium swallow demonstrated dilated mid-distal esophagus with "bird beaking" appearance.
