In Vitro Drug Dissolution: Alternative Methods01:17

In Vitro Drug Dissolution: Alternative Methods

296
Alternative drug dissolution methods include the rotating bottle, intrinsic dissolution test, peristalsis, and the Franz diffusion cell method. The rotating bottle method involves meticulously rotating tightly capped controlled-release beads in a temperature-controlled bath. Periodic decanting of samples allows for residue assay, followed by refilling with fresh medium and testing at various pH levels to emulate the gastrointestinal tract conditions.In contrast, the intrinsic dissolution test...

Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids

768
In the complex environment of the gastric lumen, excessive acid secretion can lead to the formation or worsening of ulcers within the delicate mucosal layer. Antacids, such as sodium bicarbonate and calcium carbonate, provide relief by neutralizing this acid, transforming it into harmless salt and water. This neutralization process raises the gastric pH from a highly acidic level of 1 to a more basic 3-4, reducing the acidity within the stomach.
However, this neutralization reaction between...

Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents

1.8K
In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...

Factors Affecting Dissolution: Particle Size and Effective Surface Area

1.8K
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are...

Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors

1.0K
Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.
Gastric acid, a potent cocktail of hydrogen and chloride ions, is produced in specialized parietal cells within the...

    Area of Science:

    • Gastroenterology
    • Pharmacology

    Background:

    • Retained cholesterol gallstones after cholecystectomy pose a clinical challenge.
    • Monooctanoin, a medium chain triglyceride derivative, acts as a cholesterol solvent.

    Purpose of the Study:

    • To evaluate the efficacy and safety of monooctanoin for dissolving retained cholesterol gallstones.
    • To assess monooctanoin as an alternative treatment when mechanical stone removal is not possible.

    Main Methods:

    • Bile duct infusion of monooctanoin was administered to patients with retained gallstones.
    • Efficacy was determined by the rate of complete gallstone dissolution.
    • Toxicity and side effects were monitored.

    Main Results:

    • Complete gallstone dissolution was achieved in 50-75% of treated patients.
    • Monooctanoin demonstrated minimal toxicity with bile duct infusion.
    • Common gastrointestinal side effects included anorexia, nausea, vomiting, diarrhea, and abdominal pain.

    Conclusions:

    • Monooctanoin is an effective agent for cholesterol gallstone dissolution.
    • It presents a viable option for patients unsuitable for or unresponsive to mechanical stone removal.
    • While generally safe, potential absorption and infiltration risks necessitate careful administration.
