Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents

Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Cholinergic Antagonists: Pharmacokinetics

Cholinergic antagonists—such as antimuscarinics—are available in oral, topical, ocular, parenteral, and inhalational formulations. Most antimuscarinics are oral formulations, while scopolamine is available as a topical patch, and ipratropium and tiotropium are available as inhalation aerosols or powders. Atropine, tropicamide, and cyclopentolate are topically instilled in the eye. Most antimuscarinics are lipid-soluble and readily absorbed from the gastrointestinal tract and...
