A suppository is a solid dosage form in which one or more APIs are dispersed in a suitable base and molded or otherwise formed into a suitable shape for insertion into the rectum to provide local or systemic effect
The presentation deals with a detailed study of soft gelatin capsules. this involves the production of soft gelatin capsule based on the importance of base adsorption factor and minim/gram factor. also quality control studies was also elaborated.

Types
Type A – derived from an acid treated precursor
isoelectric point in the region of pH 9.0
Type B – derived from an alkali treated precursor
isoelectric point in the region of pH 4.7
3. Manufacture of Gelatin

8. Q C Tests
Content Uniformity
I. Determine content of active ingredient – 10 caps. – Average - less than 15% (85-
115%)- Passes
2 or more – over 15% & less than 25% - II
II. Determine content of AI in 20 more – Average of 30 caps – Not more than 3 over 15%
& less than 25% - (75-125%) Passes
Weight Variation
I. Wt. of 20 caps – Average – all less than 10% - (90-110%) Passes
1 or more out of limit (more than 10% and less than 25% – II
II. Wt. of intact cap – open, empty contents & weight empty caps – More than 3 deviates
– III
III. Wt. of 40 more – Average of 60 caps – Not more than 6 deviates - Passes
Disintegration
I. 6 – if 1 fails – 12 more – Not less than 16 of 18 should disintegrate – Passes
Dissolution
10. Intro
Medicaments enclosed in a soft, soluble gelatin shells
Also known as Soft Elastic Capsules or Soft Gels
Advantages
Liq. To solid form
Dosage uniformity & accuracy
Bioavailability
Lesser irritation in stomach
Sealed – suit able for liquid and volatile drugs
Atmospheric oxidation is prevented
Elegant in appearance
Can be prepared as Suppositories or Pessaries
Breath fresheners, perfumes, bath oils, suntan oils and skin
creams
11. Disadvantages
Limited no. of firms have the filling facility
Expensive when compared to direct compression tabs.
Intimate contact with the shell – oily vehicles-proteolytic effect
Not suitable for water miscible and volatile liquids – migrate into hydrophilic shell
Glycerin and PG cannot be the major constituent – Soften the gelatin
Not suited for acidic subs. – Hydrolysis and leakage
Not suited for alkaline subs. – Tan the shell and affect solubility
Substances not stable in the presence of moisture
Formulation of Soft Gelatin Shell
Gelatin
Water
Plasticizers –glycerin, sorbitol, propylene glycol
Coloring agents – H2O soluble dyes, lakes, pigments, veg. colors
Opacifying agents – Titanium dioxide
Flavouring agents – Ethyl vanillin, essential oils (not more than 2%)
Sweetening agents – Sucrose (not more than 5%)
Preservatives – Methyl & Propyl paraben, Sod. metabisulphite, Pot. Bisulphite
Acids – Fumaric acid to aid solubility
