Serious Adverse Events Following Chewing or Crushing Sustained-Release Medications Here are just a few examples published in the medical literature of patients who have been injured or have died after ingesting a sustained-release drug that was chewed or crushed: A year-old woman was hospitalized for a stroke.
Physiologic characteristics include. Food, other drugs, and digestive disorders can affect drug absorption and bioavailability. For example, high-fiber foods and calcium supplements may bind with a drug and prevent it from being absorbed.
Laxatives and diarrhea, which speed up the passage of substances through the digestive tract, may reduce drug absorption. Surgical removal of parts of the digestive tract such as the stomach or colon may also affect drug absorption. Where and how long a drug product is stored can affect drug bioavailability. The drug in some products deteriorates and becomes ineffective or harmful if stored improperly or kept too long.
Some products must be stored in the refrigerator or in a cool, dry, or dark place. Storage directions and expiration dates should be strictly adhered to complied with at all times. Merck and Co.

Which way is best will depend partly on the area of the gut affected by your IBD and partly on the nature of the drug itself.
Most of the drugs used for IBD have a tablet, capsule or granule form, so can be taken by mouth. Many people with IBD find this a convenient way to take their medication and it is easy for a doctor to change dosage levels if necessary.
This makes sure the drug is released in the right part of the digestive system — usually the small intestine small bowel or large intestine colon. This is why it can be important to swallow tablets or capsules whole and not to break or crush them. Taking a drug topically means applying it directly to the affected part of the body. This can mean that the drug works more efficiently. Another advantage can be that other parts of the body are not so readily affected by the drug, and this can reduce possible side effects.
Fish gelatin capsules. They are preferred for filling marine supplements such as EPA [eicosapentaenoic acid]-rich fish oil. Starch capsules. Starch capsules are made from potato starch. Their dissolution is pH independent, and they are suitable for enteric coating.
Pullulan capsules. These vegetarian capsules are made from tapioca, which is naturally fermented into pullulan. They provide a high barrier to oxygen. Polyvinl acetate PVA capsules. PEG when used as single vehicle is not compatible with other hard capsules. The oxygen permeability of PVA is low, resulting in a high barrier to oxygen. Liquid-filled hard capsules LFHC. LFHC can also be filled with tablets, pellets, or other capsules as combination fill. LFHC can be used for moisture-sensitive drugs.
These can be a cost-effective alternative to some soft gelatin capsule products and can also enhance bioavailability and improve product stability. Liquid encapsulation technology helps overcome many problems associated with the use of softgel capsules including high cost, waste, cross-contamination, migration of the drug into the capsule shell, and issues with low bioavailability.
Liquid-filled and semi-solid capsules by their nature are resistant to crushing and powdering and therefore provide a good basis for developing an abuse-resistant formulation. These capsules can also be enteric coated. HPMC hard capsules do not become brittle when they lose water 2. Soft gelatin capsules SGC. SGC have soft, globular, gelatin shells somewhat thicker than that of hard gelatin capsules. The gelation is plasticized by the addition of glycerin, sorbitol, or a similar polyol.
It may contain preservative to prevent the fungal growth. Large-scale production methods are generally required for the preparation of SGC. Consumer preference. The growing interest in capsules as a formulation is consumer driven. Consumers prefer capsules because they are tasteless, odorless, and easier to swallow.
Capsules are also considered to work faster and better. This preference has prompted pharmaceutical manufacturers to market products in capsule form even if the product already has been produced in tablet form.
