Sterile dosage forms are those which are free from any microorganisms, dust, fibres, and foreign particles, and should be isotonic.

Parenteral preparations as name suggests (par+enteral) are those which are administered other than enteral routes.

 

Injectables:

Injectables are used to relax facial wrinkles and folds (such as “smile lines”), contour the body (such as reducing the appearance of a “double chin”) and improve the signs of facial fat loss by creating structure, framework and volume to the face and lips.



Eye drops:

These are the aqueous or oily solution or suspension that are installed into the conjunctival sac of the eye.

These are used as anaesthetics, anti-inflammatory agents, antiseptics, diagnostic agent, mitotics, mydriatics and artificial tears.

Examples:

  • Atropine sulphate eyedrops
  • Physostigmine eyedrops
  • Hyoscine eyedrops

 

Eye ointment:

  • These are placed in the conjunctival sac or applied to the margins of the eyelids. Ointments are thicker than drops and that means they can stay in your eye longer.
  • They are used when the medicine needs to work directly in your eye to relieve or treat eye conditions.

Eg: Bacitracin, ophthalmic ointment.
