An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. [1] This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine). [2]
Enteral administration may be divided into three different categories, depending on the entrance point into the GI tract: oral (by mouth), gastric (through the stomach), and rectal (from the rectum). (Gastric introduction involves the use of a tube through the nasal passage ( NG tube ) or a tube in the belly leading directly to the stomach ...
Buccal tablets offer many advantages over other solid dosage forms also intended for oral administration (e.g. enteric-coated tablets, chewable tablets, and capsules). Buccal tablets can be considered in patients who experience difficulty in swallowing, since these tablets are absorbed into the blood stream between the gum and cheek.
A tablet (also known as a pill) is a pharmaceutical oral dosage form (oral solid dosage, or OSD) or solid unit dosage form. Tablets may be defined as the solid unit dosage form of medication with suitable excipients. It comprises a mixture of active substances and excipients, usually in powder form, that are pressed or compacted into a solid ...
Single 20 to 40 mg oral doses generally give rise to peak plasma esomeprazole concentrations of 0.5-1.0 mg/L within 1–4 hours, but after several days of once-daily administration, these levels may increase by about 50%. A 30-minute intravenous infusion of a similar dose usually produces peak plasma levels on the order of 1–3 mg/L. The drug ...
Enteric coated tablets are designed to dissolve in the intestine, not the stomach, because the drug present in the tablet causes irritation in the stomach. Administering medication rectally. The rectal route is an effective route of administration for many medications, especially those used at the end of life.
Absorption is the journey of a drug travelling from the site of administration to the site of action. [1] [2]The drug travels by some route of administration (oral, topical-dermal, etc.) in a chosen dosage form (e.g., tablets, capsules, or in solution). [3]
Some methods to create a solvent-free film coating include injection molding coating, hot-melt coating, and spray congealing. [1] Each method has its own advantages and disadvantages, but the common theme amongst them is the need for very precise conditions that can satisfactorily apply a film coating to the oral dosage form.
