Abstract

The skin is the largest organ of the body is subjected to different conditions that threaten its integrity - pathogenic invasion and other circumstances. The elimination of these skin infections and the maintenance of skin integrity, thus, are paramount importance against the invasion of microorganism and setting in of more serious and systemic infections. Hence, we created a fixed dose ointment preparation that contains Mupirocin 2 pcnt and zinc oxide 10 pcnt . Mupirocin is a natural antibacterial produced from the fermentation of bacteria Pseudomonas flourescens that has an antimicrobial activity against gram positive bacteria. Zinc oxide is an inorganic compound appearing as a white powdery substance that is used as an additive to dermatological preparations for its drying and antibacterial properties. When Mupirocin and Zinc Oxide are combined together they exhibit enhanced bactericidal and protective effect. The combination of these two targets to eliminate susceptible infections and promote re-epitherlialization to hasten the wound healing process. The ointment was chosen as the vehicle for this dermatological preparation owning the hydrophobic characteristic of the two components. This will render greater miscibility between the two. The ointment is also desired since it adheres to both dry and wet surfaces and gives better occlusion, considering the nature of skin lesions for which the preparation is indicated.

Description

CINZOTECT a) A brief statement of its nature and purposes
Mupirocin is a naturally-occurring antibiotic obtained from fermentation of the bacteria
Pseudomonas fluorescens. It is both bacteriostatic and bactericidal at appropriate concentrations to susceptible organisms of the Staphylococcus and Streptococcus genera.
These organisms are found on the skin and commonly infect skin lesions. Mupirocin was approved for use as a topical preparation by the US FDA in 1987 and as an intranasal formulation in 1995. It is currently available in the local market under various trade names.
Zinc Oxide is an inorganic compound commonly added in dermatological preparations for its drying and anti-bacterial properties. More recent and comprehensive studies have shown that zinc oxide is an important cofactor for the activity of numerous enzymes needed for bodily functions such as immunity and wound healing.
The ointment was chosen as the vehicle for this dermatological preparation owing to the hydrophobic characteristic of the two components. This will render greater miscibility between the two. The ointment is also desired since it adheres to both dry and wet surfaces and gives better occlusion, considering the nature of skin lesions for which the preparation is indicated. b) Complete and detailed enabling description
MUPIROCIN
Mupirocin is a natural antibacterial produced from fermentation of the bacteria Pseudomonas fluorescens. Its chemical formula is C2sHa4Os and its IUPAC name is 9-[(E)-4-[(2S,3R,4R,5S)- 3,4-dihydroxy-5-[[(2S,3S)-3- [(2S,3S)-3-hydroxybutan-2-yljoxiran-2-yljmethyl] oxan-2-yl}-3- methylbut-2-enoylJoxynonanoic acid.
It is a mixture of several pseudomonic acids. At least 90% of this mixture is characterized as
Pseudomonic acid A (PA-A). The remaining acids are characterized as: Pseudomonic acid B (PA-B) with an additional hydroxyl group at C8; Pseudomonic acid C (PA-C) with a double bond between C10 and C11, instead of the epoxide of PA-A; and Pseudomonic acid D (PA-D) with a double bond at C4" and C5’ in the 9-hydroxy-nonanoic acid portion of mupirocin.
: ACTION
Topical Antibacterial
MECHANISM OF ACTION
Mupirocin is bacteriostatic at low concentrations and bactericidal at high concentrations.
However, it is possible to achieve these bactericidal concentrations with topical preparations.
Mupirocin is able to inhibit protein synthesis by binding to the isoleucyl t-RNA synthetase in Staphylococcus and Streptococcus bacteria. There is no in vitro cross-resistance with other antimicrobials and resistance is rare.
Its antimicrobial activity has been proven against the following Gram-positive bacteria:
Staphylococcus aureus, Streptococcus pyogenes (Group A beta-hemolytic), Staph. epidermidis and Staph. Saphrophyticus. It is also active against some Gram-negative bacteria but has no antimicrobial activity against anaerobic bacteria, Chlamydia and fungi.
INDICATIONS AND USAGE
Mupirocin is used to treat primarily and secondarily infected skin lesions by susceptible organisms such as impetigo, furuncles, carbuncles, open wounds, dermatoses, abrasions, insect bites, minor cuts, minor burns, ulcers and for the prevention of infection in suture wounds.
ZINC OXIDE
Zinc oxide is an inorganic compound appearing as a white powdery substance.
Zinc Oxide is used as an additive to dermatological preparations for its drying and antibacterial properties. It also becomes an effective barrier on the skin as it is not absorbed readily by the skin.
ACTIONS
Enhances re-epithelialization, drying, antibacterial
MECHANISM OF ACTION
Zinc Oxide has been shown to be an important cofactor in the activity of more than 300 enzymes in the body which, in tum, are necessary for maintaining and enhancing immune functions and other physiological processes as re-epithelization in wound healing. Specifically, zinc oxide has been shown to upregulate factors such as Insulin-like Growth Factor-1 and the activity of matrix metalloproteinase enzymes needed to induce the mitotic activity of cells in the basal layer of the epidermis.
: INDICATIONS AND USAGE
Zinc oxide in topical preparations may be applied to minor bums, cuts, incontinence- associated dermatitis (or diaper rash) or where protection of the skin and maintenance of skin integrity is desired in those with chafing, chapping, excoriations, eczema, ostomy sites and surgical wounds. d) Distinct and explicit claims we seek to be protected e Brand Name:
