The evaluation of ointment base experiment

Formulation 4 has the lowest concentration of acetylsalicylic acid in distilled water. The results of the physical evaluation of ointment preparation with m ethanolic extract s of C. When a steady state has been reached diffusion through stratum corneam becomes the dominated pathway.

This test was performed on albino rats and weighing between g. It inhibits water loss from the skin by forming a greasy layer, and this in turns improves the hydration of the skin in dry scaly conditions.

In the case of a protective ointment, it serves to protect the skin against moisture, air, sun rays and other external factors. Cooled under stirring and soft mass of ointment is obtained. June 01, ; Published: In the first stage of wound, an inflammatory response occurs, which is characterized by hemostasis and inflammation.

This permeation can be possible only if the drug possesses certain physicochemical. The quantity emulsifying wax in the formulation will also cause the hardness of the ointment to vary. Physicochemical evaluations and stability studies of different formulation of ointments Table 3: The quantity emulsifying wax in the formulation will also cause the hardness of the ointment to vary.

Acid soluble collagen was estimated using collagen-Type I as a standard. Factor affecting topical permeation: The objective was to study the impact of drug loading and type of ointment base on the in vitro performance IVRT and IVPT of ophthalmic ointments using acyclovir as a model drug candidate.

Based on the results of these tests, trails may be performed on human beings. Ointment is composed mostly of fluid hydrocarbons meshed in a matrix of higher melting solid hydrocarbons. Male Swiss albino mice g were used in the study and maintained under standard laboratory conditions of housing, food and water.

Thus, these formulations encourage the diffusion of drugs into the distilled water through the membrane.

Although there is a high amount of liquid paraffin to assist in the diffusion of acetylsalicylic acid, but insufficient emulsifying wax causes acetylsalicylic acid unable to disperse properly in ointment.

The other agents including extracts in different concentration were dissolved in purified water are added with stirring until the mixture congeals.Evaluation of different effects of ingredients towards the ointment formulation. Objective: To study the effect of ointment composition towards the physical properties of the ointment and the rate of drugs release from the ointment formulation.

oleaginous bases; absorption bases ; water in oil emulsion bases; oil in water emulsion bases ; water soluble or water miscible bases ; Each ointment base type has different physical characteristics and therapeutic uses based upon the nature of its components.

Background: This study examined the in vitro antibacterial property of extracts of Moringa oleifera and the effect of different concentrations of the ethyl-acetate extract on cuta. Formulation and evaluation of antiarthritic (anti-inflammatory) herbal preparation (Ointment) containing Menthol and Methyl Salicylate.

The Ointment formulation was designed by using five different ointment bases. Various formulation batches containing 5% Menthol and 15% Methyl Salicylate were prepared.

Clove Oil was used as a penetration enhancer.
