A pharmacist is the person of drugs or the expert on drugs. S/he is the only expert on drugs, for expertise regarding drugs requires knowledge in depth in all the facts of pharmacy. It is his/her professional responsibility to know all about the drugs. No educational program other than that in pharmacy provides the background to understand completely all about drugs.

Among the professions of pharmacists like community pharmacy, institutional pharmacy, whole sale pharmacy, industrial pharmacy, government service, pharmaceutical education, organizational management, in my country industrial pharmacy offers great opportunity to the pharmacists.

Industrial pharmacy is a profession of unique hybrid of business and profession.

So an industrial pharmacist should have proper knowledge about drugs and also about medical progress, commence marketing and technology. To be a self-sufficient pharmacist beside academic knowledge, practical knowledge is essential.

This is why after appearing the Bachelor of Pharmacy examination in-plant training was arranged by the discipline in renowned ORION Laboratories Ltd.. This training has sharpened our academic knowledge what we learnt in the last few years .We have completed training in Orion Laboratories Ltd. a fast growing pharmaceutical company in Bangladesh.

Tablet Section

Tablets may be defined as the solid unit dosage form of medicament or medicaments with or without suitable diluents or excipients and prepared either by molding or by compression. They vary greatly in shape, size and weight which depend upon the amount of medicament and the mode of administration. Excipients may include diluents, binders, disintegrating agents, lubricants, sweetening agents, flavoring and coloring agents.


Tablets have following advantages:

  1. Easy to carry.
  2. Easy to swallow and may provide the greatest ease of swallowing with the least tendency for “hang-up” above the stomach, especially when coated, provided that tablet disintegration is not excessively rapid.
  3. They lend themselves to certain special – release profile products, such as enteric or delay-release products.
  4. Attractive in appearance.
  5. Unpleasant taste can be masked by coating.
  6. Do not require any measurement of dose.
  7. Can be divided into halves and quarters by drawing lines during manufacturing to facilitate breakage whenever a fractional dose is required.
  8. An accurate amount of medicament even if very small can be incorporated.
  9. Tablets provide prolong stability to medicament.
  10. The incompatibilities of medicaments and their deterioration due to environmental factors are less in tablet form.
  11. Since they are generally produced on a large scale therefore their cost of production is relatively low.
  12. They have the best combined properties of chemical, mechanical and microbiologic stability of all the oral forms.

During training we have observed the manufacturing of the following tablets:

· Nidazyl

· EC Plus

· Deslor

· Maxical Plus

Different solid manufacturing unit

The different solid manufacturing units are:

§ Dispensing unit

§ Granulation unit

During tablet manufacturing, the raw materials needed for a batch of drugs are taken from the Warehouse (RM&PM) department after accurate weighing and to the production area. These materials then go for granulation, milling, blending and drying processes as required. Plain tablets and tablets cores are produced in the various compression rooms using the machinery listed previously.

After compression, many tablet cores get a coating. Products then wait in quarantine area in Finished Goods Store, until the quality control laboratory confirms their standardized quality and authorizes their release. The whole process of tablet manufacturing ensures “Good Manufacturing Practice.”




The oral use of liquid Pharmaceutical has generally been justified on the basis of ease of administration to those who have difficulty in swallowing solid dosage form. A drug administer in solution is immediately available for absorption and in most case is more rapidly and efficiently absorbed than the same amount of drug administered in tablet and capsules.

In liquid section oral suspension, syrup etc. are manufactured. During my visit, I have observed the manufacturing of

  • Deslor syrup
  • Orioplex syrup
  • Pep-2 syrup

Syrup/Elixir/Emulsion: These products are filled into clean glass bottle and sealed by automatic bottle filling and sealing machine

· Secondary packaging

· Cartooning/Box: After primary packing products are pack into paper/printed cartoon. In this time, Batch no. Mfg date, Exp date must be check and maintain strictly.

· Master cartooning: Small individual cartoons or boxes are pack into fibre board cartoon according to batch no, it is called master cartooning.



Capsules are the solid unit dosage form of medicament in which the drug(s) is enclosed in a practically tasteless, hard or soft soluble container or shell made up of a suitable form of gelatin.

Gelatin shells are supplied in a number of sizes. The number varies from 000 to 5, the former being the largest and later the smallest. The exact amount of a medicament which can be filled in a particular size of capsule shell depends upon density of the material to be filled in. Generally the capacity varies from 600mg to 30mg.


  • Capsules are tasteless, odorless and can be easily administered.
  • Attractive in appearance.
  • The drugs having unpleasant odor and taste are enclosed in a tasteless shell.
  • They can be filled quickly and conveniently therefore the physician can change the dose and combination of drugs to suit the individual patient. This is an advantage over tablets.
  • Flexibility in onset and duration of action also contribute to the suitability of the capsule as a pharmaceutical dosage form.
  • Ease of formulation.
  • Limited potential for incompatibilities.
  • Good stability.
  • Easy to swallow.
  • They are economical.
  • They are easy to handle and carry.


· Capsules are not usually used for the administration of extremely soluble materials such as potassium chloride or ammonium chloride.

· Capsules should not be used for highly effervescent or deliquescent materials. Effervescent materials may cause the capsule to soften.

· Deliquescent powders may dry the capsule shell to excessive brittleness.

· The concentrated solutions which require previous dilution are unsuitable for capsules because if administered as such lead to irritation in the stomach.

Capsule shell has two parts: Body and cap. Several designs of locking systems in the capsule shells are available.

During my visit I have observed the manufacturing of following capsules.
