Capsule dosage forms

The pharmaeeutieal industry began to take over the produetion of most medications used by the medieal profession. In many ways this has provided superior service, new methods, and a vast array of innovative products that could not have been provided in a one-on-one situation. Research and development have been the hallmarks of the pharmaeeutieal manufaeturers. However, the very nature of providing millions of doses of a produet requires that the dosage forms (capsule, tablet, suppository) and doses (individual strengths of eaeh dose) be limited and results in a one-sided approach to therapy. It is simply not eeonomical for a pharmaeeutieal eompany to produce a produet in 50 different eoneeivable doses, or 15 different dosage forms, to meet the needs of the entire range of patients reeeiving therapy. Windows of activity are determined whieh meet most patient needs, but the very nature of the process is not able to meet all patient needs. 

Even if the same drug substance HPLC method is used for the drug product, forced decomposition studies must be performed again for the drug product to confirm the resolution of potential degradation products from the API. In addition, forced decomposition studies must also be performed for different dosage forms (capsule, tablet, suspension, injectable, etc.) of the same drug substance. 

HBS Hydrodynamically balanced system. A CR oral dosage form (capsule or tablet), which is designed to prolong the residence time within the stomach. Increased time for dissolution, prolonged absorption phase, and improved pharmacokinetic profile. Madopar HBS or Prolopa HBS (L-dopa + Benserazide) Vahelease (diazepam).

As a therapeutic agent, ch oline is adininistered orally in the form of symps or elixers containing the chloride, citrates or bitartrate, or in the form of compressed tablets or capsules of the dihydrogen citrate. Choline is also given in small doses as a nutritional supplement in combination with a variety of other materials. In dry pharmaceutical-dosage forms, the dihydrogen citrate is usually preferred because of its lower tendency to absorb atmospheric moisture. Both salts have been used parenteraHy. 

ORAL ADM IN I STRATI ON. The nurse can administer oral preparations without regard to meals. Tablets can be crushed and mixed with food or fluids if the patient has difficulty swallowing. Do not alternate between the dosage forms (ie, the tablets and the capsules). Dosses are not the same The recommended dosage of the capsules is 80% of the dosage for tablets and elixir. 

Do not inhale the powder dosage form or powder from capsules because it may irritate the skin or mucous membranes. 

Some antihistamines such as diphenhydramine, dimenhy-drinate, and meclizine are available without a prescription, making self-treatment convenient for patients. Antihistamines are available in a variety of dosage forms, including oral capsules, tablets and liquids. Liquid formulations are convenient for children or adults who are unable to swallow solid dosage forms.

The effect of particle size reduction on the bioavailability of nitrofurantoin was shown in Fig. 4. The microcrystalline form (< 10 pm) is more rapidly and completely absorbed from the tablet dosage form than is the macrocrystalline form (74-177 pm) from the capsule dosage form. This is not a completely satisfactory illustration of the effect of particle size on the rate and extent of availability, since other manufacturing variables have not been held constant. Nevertheless, it does suggest some correlation between particle size, dissolution rate, and rate of availability.
