WHY IS PSORIASIS IMPORTANT FOR COMMUNITY PHARMACY? Psoriasis is a common skin condition that affects between 2 - 3% of the general population in Britain. In Scotland, it is estimated that around 150,000 people are currently living with some form of the condition.1 Psoriasis can become apparent at any age, however most often develops in adults under the age of 35 years. The condition affects men and women equally, and the severity of the conditions can vary greatly from person to person. In many people the condition represents a minor irritation,
however for others, it has a significant impact on their day-to-day lives, and can severely impact on their quality of life. Community pharmacy presents an access point for people suffering with this condition, as pharmacy staff knowledgeable in the disease state, are able to provide treatment options and information to help with the management of the condition.
WHAT IS PSORIASIS? Psoriasis is a skin condition, characterised primarily by red, flaky, crusty patches of skin covered with silvery scales. There are many different
forms of psoriasis and usually patients will experience periods of fewer symptoms followed by flare-ups, where symptoms will be much more apparent.
The most common form of psoriasis is Plaque psoriasis, accounting for up to 90% of cases. Here we see red, flaky, crusty patches of skin covered with silvery scales. These patches are most common at flexural points on the body, for example in the creases of the elbows and knees. In severe cases the skin around these joints can crack, split and bleed.
Scalp psoriasis affects parts of, or the entire scalp of a person. Some people find this to be extremely itchy, however many have no sensation of discomfort at all. Nail psoriasis is apparent in around 50% of patients suffering from psoriasis. Here the nails can develop small pits or dents, become discoloured and grow abnormally. Nails can become loose, dislodge and in severe cases will crumble.2
Guttate psoriasis (from Gutta, Latin for drop, spot, or speck) is characterised by the formation of small, <1cm sores
