Effect of bolus composition on esophageal transit: concise communication
Summary
Swallowing pills with water and in a sitting position improves esophageal transit. This simple technique can prevent medication-induced esophageal injury, such as esophagitis or erosions.
Area of Science:
- Gastroenterology
- Nuclear Medicine
- Pharmacology
Background:
- Esophageal transit disorders can lead to complications like esophagitis.
- Non-invasive methods are needed to assess esophageal function.
- Solid medications can cause esophageal injury if not properly swallowed.
Purpose of the Study:
- To evaluate the impact of posture and liquid/solid consistency on esophageal transit.
- To determine optimal conditions for swallowing solid medications.
- To reduce the incidence of medication-related esophageal damage.
Main Methods:
- Esophageal scintigraphy was used in 40 healthy volunteers.
- Transit of liquids, capsules, and solid food (chicken liver) was assessed.
- Factors studied included body posture (sitting vs. supine) and water intake.
Main Results:
- Liquids cleared completely in one swallow, regardless of posture.
- Solid capsules or food frequently remained in the esophagus without sensation when swallowed without water.
- Upright posture improved clearance of solids compared to supine.
- Swallowing capsules with 15ml water after a sip ensured complete transit.
Conclusions:
- Assisting patients to a sitting position and having them sip water before swallowing medication improves esophageal transit.
- This practice may decrease esophagitis from oral antibiotics and erosions from aspirin.
- Esophageal scintigraphy is a valuable tool for studying esophageal transit dynamics.

01:18Routes of Drug Administration: Enteral
Medications can be administered through the enteral route using liquids, capsules, or tablets.
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

01:24Upper GI Series: Barium Swallow
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.

01:18Drug Delivery: Enteral Route
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

01:20Factors Affecting Dissolution: Drug Permeability, Stability and Stereochemistry
Orally administered drugs primarily enter the systemic circulation via passive diffusion through the intestinal membranes. The drug's absorption is influenced by drug stability in the gastrointestinal GI tract, membrane permeability, the surface area available for absorption, luminal drug concentration, and residence time in the lumen. Drug permeability can be enhanced by adjusting the lipophilicity, polarity, or molecular size of the drug, promoting its passive transport across intestinal...
01:19One-Compartment Open Model for IV Bolus Administration: General Considerations
The one-compartment model is a pharmacokinetic tool that models the body as a single, uniform compartment, facilitating the understanding of drug distribution and elimination. This model is particularly beneficial for intravenous (IV) bolus administration, where the drug rapidly circulates throughout the body.
The drug's presence in the body is defined by an equation representing the difference between the rates of drug entry and exit. Key parameters—elimination rate constant, half-life,...

01:18Formulation and Manufacturing Process: Physical Attributes of Generic Tablets and Capsules
Bioequivalence in generic drugs, such as tablets and capsules, refers to their pharmaceutical equivalence to the brand-name counterparts. However, for therapeutic equivalence, manufacturers must also consider physical attributes like size, shape, and weight (FDA Guidance for Industry, December 2003). Discrepancies in these aspects could impact patient compliance and cause medication errors. For instance, swallowing difficulties, often experienced with larger tablets or capsules, can lead to...
