4 CLINICAL PARTICULARS

4.1 Therapeutic indications

Videne Surgical Scrub is a broad-spectrum antiseptic for topical use. It is indicated for preoperative hand disinfection by the surgical team, or for disinfecting the site of incision prior to elective surgery.

4.2 Posology and method of administration

Pre-operative surgical scrub – after first wetting the hands and arms with water, approximately 3.5ml of Videne Surgical Scrub is applied and rubbed thoroughly on to these areas. A brush may be used to scrub the nails. A little water is added to develop a lather and finally this must be rinsed off with running water.

Pre-operative skin preparation – the site of incision should be washed with Videne Surgical Scrub two or three times a day prior to the operation.

Immediately before surgery the skin should be moistened with water, Videne Surgical Scrub applied and rubbed thoroughly into the area for several minutes. A sterile gauze swab is used to develop a lather which must be finally rinsed off with water.

Only water should be used to dilute Videne Surgical Scrub.

Neonates:

Do not use on neonates, refer to Section 4.3 Contraindi­cations.

Children and Elderly:

There are no special dosage recommendations for children or elderly patients.

Renal Impairment:

Patients with renal impairment should refer to Section 4.4, special warnings and precautions for use.

4.3 Contraindications

Videne Surgical Scrub must never be administered orally, and is contraindicated in neonates, and during pregnancy and lactation.

Regular or prolonged use should be avoided in patients with thyroid disorders or those receiving lithium therapy.

Hypersensitivity to any of the ingredients.

4.4 Special warnings and precautions for use

Care must be taken when Videne Surgical Scrub is used on known iodinesensitive subjects, although such people do not normally react to iodinated povidone.

The application of povidone-iodine to large wounds or severe burns may produce systemic adverse effects such as metabolic acidosis, hypernatraemia, and impairment of renal function.

4.5 Interactions with other medicinal products and other forms of interaction

It is to be expected that povidone-iodine reacts with protein and various other organic substances such as blood and pus components, for example. This interaction may impair efficacy.

As a result of oxidation, the concomitant application of Videne Surgical Scrub and enzymatic wound treatment agents weakens the action of the enzyme components of both drugs. The latter is also true of hydrogen peroxide and taurolidine as well as of disinfectants containing silver (formation of silver iodide).

Videne Surgical Scrub must not be used concomitantly or immediately following disinfectants containing mercury (risk of chemical burns due to the formation of mercury iodide).

Videne Surgical Scrub must not be used concomitantly with or immediately after the application of octenidine-based antiseptics to the same or adjacent areas as transient dark discolouration can occur at the areas concerned.

In patients receiving concomitant lithium therapy, regular application of Videne Surgical Scrub should be avoided as, especially in the case of application of povidone-iodine to extensive areas, larger amounts of iodine may be absorbed. In exceptional cases, this can induce (transient) hypothyroidism. In this special situation, a synergistic effect might also occur as lithium may also induce hypothyroidism.

Due to the oxidising action of povidone-iodine, when patients are undergoing treatment with Videne Surgical Scrub various diagnostic agents can give falsepositive results (inter alia toluidine and guaiac resin for the determination of haemoglobin or glucose in the stools or urine).

During the application of povidone-iodine uptake of iodine by the thyroid gland may be reduced; this can lead to disturbances in thyroid scanning, PBI (proteinbound iodine) determination and radioiodine diagnostics and make planned radioiodine therapy impossible. A waiting period of at least 1–2 weeks should be observed after discontinuing the povidone-iodine treatment before conducting a new thyroid scan.

4.6 Pregnancy and lactation

Videne Surgical Scrub is not recommended for use during pregnancy because of the possibility of absorption through skin and subsequent interference with tests of neonatal thyroid function. Videne Surgical Scrub should not be used in neonates or during lactation. Refer to Section 4.3, Contraindications.

4.7 Effects on ability to drive and use machines

None stated.

4.8 Undesirable effects

In very rare instances Videne Surgical Scrub may produce skin reactions in iodinesensitive subjects. These reactions subside on cessation of treatment.

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system: Yellow Card Scheme, Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

In cases where Videne Surgical Scrub has been taken orally, gastric lavage with dilute starch mucilage or a 1 % solution of sodium thiosulphate must be administered. The electrolyte balance must be corrected and lost fluids replaced.

5.1 Pharmacodynamic properties

ATC Code:   D08AG02

Dermatological­s/Antiseptics and Disinfectants/po­vidone-iodine

Povidone-iodine has antiseptic activity and is mainly used for the treatment of contaminated wounds and pre-operative preparation of skin and mucous membranes. It is considered to be less irritant than iodine.

5.2 Pharmacokinetic properties

Povidone-iodine is slightly absorbed when applied to the skin. lodides are excreted mainly in the urine, with smaller amounts appearing in the faeces, saliva and sweat.

5.3 Preclinical safety data

Povidone-iodine had a low acute toxicity in both dogs and cats following either oral or intraperitoneal administration. Absorption of iodine through intact skin is low following the application of solutions of povidone-iodine although systemic absorption of iodine is greatly increased if the solutions are applied to broken skin, mucous membranes or are introduced into cavities of the body. At subcutaneous dose levels of up to 75mg/Kg/day, povidone-iodine was non-teratogenic in rabbits following administration to pregnant animals during the period of organogenesis.

Some early in vitro studies indicated a possible mutagenic action for povidone-iodine. However, a number of later studies, using in vitro and in vivo test systems, do not indicate a significant level of mutagenic/genotoxic activity for povidone-iodine. Although conflicting data have been published, there is no convincing evidence to suggest that povidone-iodine adversely affects wound healing. Concentration of 0.05 and 0.5% povidone-iodine did not cause significant ocular damage when administered into the vitreous cavities of rabbits’ eyes. There is some evidence to suggest that povidone-iodine-containing solutions applied to the round window of the chinchilla ear could result in high frequency hearing loss
