Specifically, crystalline forms dissolve slower than amorphous forms since they require more energy to leave the lattice during dissolution. The stablest crystalline polymorph has the lowest dissolution rate. Dissolution also differs between anhydrous and hydrous forms of a drug. Anhydrous forms often dissolve faster but sometimes are less soluble.
Softgels can be an effective delivery system for oral drugs, especially poorly soluble drugs. This is because the fill can contain liquid ingredients that help increase the solubility or permeability of the drug across the membranes in the body. Liquid ingredients are difficult to include in any other solid dosage form, such as a tablet.
Effervescent tablets mostly come in capsules constructed for these tablets. They may contain an anti-bacterial coating and are water resistant. The cap contains a little spring-like spiral, which helps keeping the tablets in place during transportation and prevents them from breaking. The cap also contains little balls made out of silica gel. [18]
Aqueous solutions have the advantage of being safer to deal with than solvent-based systems but may not be suitable for drugs which are degraded by hydrolysis. Procedure. The active ingredient and excipients are weighed and mixed. The wet granulate is prepared by adding the liquid binder–adhesive to the powder blend and mixing thoroughly.
The capsule cloaks antigenic proteins on the bacterial surface that would otherwise provoke an immune response and thereby lead to the destruction of the bacteria. Capsular polysaccharides are water-soluble, commonly acidic, and have molecular weights on the order of 100,000 to 2,000,000 daltons .
Sublingual strips—similar to tablets in that they easily melt in the mouth and dissolve rapidly. Suboxone is an example of medication that comes in a sublingual strip. Multi-purpose tablets—Soluble tablets for either oral or sublingual (or buccal ) administration, often also suitable for preparation of injections, Hydrostat ( hydromorphone ...
The FDA also urged consumers to avoid purchasing fat-dissolving products from websites, noting that the products might be ineffective and may carry a risk of severe side effects.
Lipophilicity (from Greek λίπος "fat" and φίλος "friendly") is the ability of a chemical compound to dissolve in fats, oils, lipids, and non-polar solvents such as hexane or toluene. Such compounds are called lipophilic (translated as "fat-loving" or "fat-liking" [1] [2]). Such non-polar solvents are themselves lipophilic, and the ...
