Derma Gran AF
Derma Gran AF Uses, Dosage, Side Effects, Food Interaction and all others data.
Derma Gran AF topical cream is a broad-spectrum antimycotic which offers a high antifungal activity against dermatophytes, yeasts and other phyco-Asco and Adelomycetes, with a potent antibacterial activity against Gram-positive bacilli and cocci. Derma Gran AF topical cream proved to be markedly effective in secondary infected mycoses, which under other treatments were resistant or reappeared. Derma Gran AF topical cream does not stain skin or clothes.
The active ingredient, Derma Gran AF, is a synthetic imidazole anti-fungal agent with a broad spectrum of activity against pathogenic fungi (including yeast and dermatophytes) and gram-positive bacteria (Staphylococcus and Streptococcus spp). It may act by interfering with the permeability of the fungal cell membranes. When administered orally, Derma Gran AF is incompletely absorbed from the gastrointestinal tract, peak plasma levels of about 1 µg per ml have been achieved after a dose of 1 gm per day. Derma Gran AF is inactivated in the body and 10-20% of an oral dose is excreted in the urine, mainly as metabolites, within 6 days. About 50% of an oral dose may be excreted unchanged in the faeces.
Derma Gran AF is an azole antifungal that functions primarily through inhibition of a specific demethylase within the CYP450 complex. As miconazole is typically applied topically and is minimally absorbed into the systemic circulation following application, the majority of patient reactions are limited to hypersensitivity and cases of anaphylaxis. Patients using intravaginal miconazole products are advised not to rely on contraceptives to prevent pregnancy and sexually transmitted infections, as well as not to use tampons concurrently.

How Derma Gran AF works
Derma Gran AF is an azole antifungal used to treat a variety of conditions, including those caused by Candida overgrowth. Unique among the azoles, miconazole is thought to act through three main mechanisms. The primary mechanism of action is through inhibition of the CYP450 14α-lanosterol demethylase enzyme, which results in altered ergosterol production and impaired cell membrane composition and permeability, which in turn leads to cation, phosphate, and low molecular weight protein leakage.
In addition, miconazole inhibits fungal peroxidase and catalase while not affecting NADH oxidase activity, leading to increased production of reactive oxygen species (ROS). Increased intracellular ROS leads to downstream pleiotropic effects and eventual apoptosis.
Lastly, likely as a result of lanosterol demethylation inhibition, miconazole causes a rise in intracellular levels of farnesol. This molecule participates in quorum sensing in Candida, preventing the transition from yeast to mycelial forms and thereby the formation of biofilms, which are more resistant to antibiotics. In addition, farnesol is an inhibitor of drug efflux ABC transporters, namely Candida CaCdr1p and CaCdr2p, which may additionally contribute to increased effectiveness of azole drugs.
Dosage
Derma Gran AF dosage
For oral administration: Dosage is based on 15 mg/kg/day.
- Adults: 1-2 tea-spoonfuls of gel four times daily
- Children aged 6 years and over: One tea-spoonful of gel four times daily
- Children aged 2-6 years: One tea-spoonful of gel twice daily
- Infants under 2 years: Half tea-spoonful of gel twice daily.
For localised lesions of the mouth:
A small amount of gel may be applied directly to the affected area with a clean finger. For topical treatment of the oropharynx, the gel should be kept in the mouth for as long as possible. Treatment should be continued for up to 2 days after the symptoms have cleared.
For oral candidasis, dental prostheses:
Should be removed at night and brushed with the gel.
The dosage is same for all the ages.
For skin infections: Apply some cream to the lesions twice daily and rub it well with finger until it has fully penetrated the skin. All lesions usually disappear after 2 to 5 weeks. Prolong treatment for some 10 days to prevent relapse.
For nail infections: Clip infected nail as shortly as possible. Apply some cream once daily to the infected nail and rub with your finger, cover nail with a non-perforated occlusive plastic bandage.
Also after loosening of the infected nail (from 2-3 weeks onwards) uniterrupted treatment should be continued until the growth of a new nail has set in and definite cure can be observed (usually after seven months or more).
Side Effects
Topical application of Derma Gran AF Nitrate has almost no side effect.
For oral gel: Occasionally, nausea and vomiting have been reported, and with long term treatment, diarrhoea. In rare instances, allergic reactions have been reported. There are isolated reports of hepatitis, for which the causal relationship with Derma Gran AF has not been established.
Toxicity
Derma Gran AF overdose has not been reported. Patients experiencing an overdose are at an increased risk of severe adverse effects such as headache, skin irritation, diarrhea, nausea, vomiting, abdominal pain, and dysgeusia. Symptomatic and supportive measures are recommended.
Derma Gran AF has an oral LD50 of 500 mg/kg in rats.
Precaution
If the concomitant use of Derma Gran AF and anticoagulants is envisaged, the anticoagulant effect should be carefully monitored and titrated. It is advisable to monitor Derma Gran AF and phenytoin levels, if they are used concomitantly. Particularly in infants and young children, caution is required to ensure that the gel does not obstruct the throat. Hence, the gel should not be applied to the back of the throat and the full dose should be divided into smaller portions. Observe the patient for possible choking.
Interaction
Derma Gran AF can inhibit the metabolism of drugs metabolised by the Cytochrome P450-3A and -2C9 families. This can result in an increase or prolongation of their effects, including side effects. Derma Gran AF Oral Gel should not be used during treatment with the following drugs: terfenadine, astemizole,mizolastine, cisapride, triazolam, oral midazolam, dofetilide, quinidine, pimozide, CYP3A4 metabolised HMG-CoA reductase inhibitors such as simvastatin and lovastatin.
Food Interaction
No interactions found.Derma Gran AF Cholesterol interaction
[Minor] Elevations in cholesterol and triglyceride levels may occur in patients receiving intravenous miconazole and are attributed to the drug vehicle, Cremophor EL (polyethoxylated castor oil).
These increases are reversible upon discontinuation of miconazole therapy.
Clinicians should be cognizant of these effects when interpreting lab results of hyperlipidemic patients during treatment with miconazole.

Derma Gran AF Disease Interaction
Volume of Distribution
A 1200 mg miconazole vaginal suppository resulted in a calculated apparent volume of distribution of 95 546 L while a 100 mg vaginal cream yielded an apparent volume of distribution of 10 911L.
Elimination Route
Derma Gran AF given to healthy volunteers as a single 50 mg oral tablet produced a mean Cmax of 15.1 ± 16.2 mcg/mL, a mean AUC0-24 of 55.2 ± 35.1 mcg*h/mL, and a median Tmax of 7 hours (range 2.0-24.1). In these patients measurable plasma concentrations ranged from 0.5 to 0.83 mcg/mL.
Topical miconazole is absorbed poorly into the systemic circulation. In pediatric patients aged 1-21 months given multiple topical applications of miconazole ointment for seven days, the plasma miconazole concentration was less than 0.5 ng/mL in 88% of the patients, with the remaining patients having a concentration of 0.57 and 0.58 ng/mL, respectively. Similarly, patients. administered with a vaginal 1200 mg ovule had a mean Cmax of 10.71 ng/mL, mean Tmax of 18.4 hours, and mean AUC0-96 of 477.3 ng*h/mL.
