![]() Tablet weight monitoring devices:- High rate of tablet output with modern press requires continuous tablet weight monitoring with electronic monitoring devices like Thomas Tablet Sentinel, Pharmakontroll and Killan control System-MC. To avoid these problems, mechanized feeder can employ to force granules into die cavity. These also seen with poorly flowing granules. Granulation Feeding Device: In many cases, speed of die table is such that the time of die under feed frame is too short to allow adequate or consistent gravity filling of die with granules, resulting in weight variation and content uniformity. Tele: E-mail addresses: Stage Occurring During Compression Auxiliary Equipments I. They are in general the easiest and cheapest to package and ship of all oral dosage forms.Their cost is lowest of all the dosage forms.Advantages of the tablets The additional advantages of tablet dosages forms are as follows: Though these tablets are now made for oral administration they are not yet recognized by the official compendia. Hypodermic Tablets (Ht) Hypodermic tablets are soft, readily soluble tablets. These tablets are supplied primarily as a convenience for extemporaneous compounding and never dispensed as a dosage form. Dispensing Tablets (Dt) These tablets provide a convenient quality of potent drug that can be incorporated readily in to powders and liquids, thus circumventing the necessity to weigh small quantities. Suitable water-soluble lubricant is many times a constraint. Such tablets must be completely and rapidly soluble. I) Layered tablets ii) Press coated tablets E) Sustained release tablets F) Tablets for solution G) Effervescent tablets H) Compressed suppositories or inserts I) Buccal and sublingual tablets Molded tablets or tablet triturates (tt) Tablet triturates usually are made from moist material, using a mold that gives them the shape of cut sections of cylinder. A) Sugar coated tablets (sct) B) Film coated tablets (fct) C) Enteric-coated tablets (ect) D) Multi compessed tablets (mct): these are compressed Tablets made by more than one compression cycle. Types of tablets Compressed Tablets The tablets are formed by compression of powdered, crystalline, or granular active materials (API), alone or in combination with certain expients as required, such as binders, disintegrants, sustained release polymers, lubricants, diluents, flavors and colorants. Compressed tablets usually are prepared by large-scale production methods, while molded tablets generally involve small-scale operations. They are divided in to two general classes by whether they are made by compression or molding. They may differ greatly in size and weight depending on the amount of the dug substance present and the intended method of administration. Although tablets frequently are discoid in shape, they also exist in several shapes such as round, oval oblong, cylindrical or triangular etc. Tabletting equipment continues to improve in both production speed and the uniformity of the tablets compressed. Efforts are being made continually to understand more clearly the physical characteristics of powder compaction and the factors affecting the availability of the drug substance from the dosage form after oral administration. Although the basic medicinal approach for their manufacture has remained the same, tablet technology has undergone great improvement. ![]() Solid dosage form provides best protection to the drug against temperature, humidity, oxygen, light and stress during transportation and also ensures accuracy of dosage, compactness, portability, blandness of taste, and ease of administration. Among the drugs that are administered orally, solid dosage form represents the preferred class of product. Nevertheless, about 90% of all the drugs used to produce systemic effects are administered by the oral route. The Parenteral route of administration is important in treating the medical emergencies in which subject is comatose or can not swallow and in providing various types of maintenance therapy. Introduction The oral route of drug administration is the most important method of drug administration for systemic effects.
