Overview of Pharmaceutical Powder Dosage Forms

Pharmaceutical Powder
Dosage Forms
 
Powder Dosage Forms
Powder are the simplest dosage forms and the basis of
many other solid dosage forms such as
TABLET,CAPSULE,etc.
Powder were originally designed as a convenient mode of
administering hard vegetable drugs such as roots, bark and
woods.
 
 
Powder Dosage Forms:
Advantages
1.
One can easily prepare the dose, and its composition’s elements
are found in a wide range.
2.
Powder doses have a higher shelf life and better physicochemical
stability than liquid dosages.
3.
Consumption of medicines in powder form can be a better
option for children and adults who suffer difficulty swallowing
capsules and tablets.
4.
Powder medication is an effective alternative for providing a
larger dose to the patient than any other.
5.
Mixing more than one medical agent provides great versatility to
the medicine.
Powder Dosage Forms: 
Disadvantage
1.
The drugs having unpleasant tastes are difficult to
consume in powder form.
2.
The powdered medicine is difficult to carry as it is heavy
and bulky.
3.
The hygroscopic drug is not good for dispensing in
powdered form.
4.
Powdered medication is not suitable where the medicine
can harm the stomach or become inactive in the stomach.
Types of Powder:
Bulk powder
The bulk powder is a finely powdered substance that
consists of medicinal drugs and can be used for internal
and external uses.
As the name implies, these powders are used in large
quantities, which can be limited by measuring them with
the help of teaspoons, cups, etc.
The major portion of bulk powder is tropical.
Types of Powder:
Dusting Powder
Dusting powders are those pharmaceutical powders that
contain single medicinal agents applied as dusting agents.
These powders are frequently used as medicinal powder
drugs and protect against skin irritation.
 The base for the dusting powder is clay, kaolin,
magnesium carbonate, talc and starch.
Douche powder is a powder drug that is used for the
cleaning solutions of intimate body parts for hygiene.
Douche powders are sometimes called douches.
 These powders are prepared for cleaning vaginal
problems.
This Powder is synthesized from the volatile substances,
and the pH lies in the parameter of 3.5 to 5.
Metal foil bags are equipped to prepare the commercial
douche powder packets.
Types of Powder:
Douche powder
Insufflations are the extremely small fine solid particles of
the pharmaceutical powder used to inject into the body.
The Powder can be easily injected into the patient’s body
with the help of the insufflator by inhaling the air current
when the insufflator bulb gets squeezed.
These packaged solutions provide an excellent solution for
administering insufflation.
Types of Powder:
Insufflations
These are finely divided solid dosage forms of
medicaments inhaled into nostrils.
FUNCTION Decongestion,Antiseptic,Bronchodilator.
PACKAGING Dispensed in flat metal boxes with hinged lid.
Types of Powder: 
Snuffs
Powder sprays are a better alternative than dusting powder as it is
dispensed with high pressure and uniform distribution in the
targeted place.
For an effective spray of the medicine on the target place, the
particles must be smaller than 50 microns if it gets packaged as a
powder spray.
Types of Powder:
Powder sprays
These types of pharmaceutical powders are those powders that are
composed of crystallized powders such as atropine, citric acid,
codeine, alums and caffeine.
This type of pharmaceutical Powder would become sticky if exposed
to a low-humidity environment as the water gets liberated from the
Powder. Drying the powder is supposed to get mixed with the bulky
Powder. Those solids which can spontaneously liberate water from
the hydrated salt are called efflorescent substances. In simple terms,
hydrated substances are generally referred to as the most
efflorescent substance. Some examples of efflorescent substances
are Na

Pharmaceutical powder dosage forms are the foundation of many solid dosage forms like tablets and capsules. They offer advantages such as ease of preparation, longer shelf life, and versatility in mixing medications. However, they also come with challenges such as unpleasant taste and difficulty in carrying. Different types of powders, including bulk powder, dusting powder, and douche powder, cater to various medicinal and hygienic needs.
