Operators of a Dublin sex shop accused of selling a Viagra-like drug without authorization will reportedly face trial in Dublin in May.

According to the Irish Independent Brian O'Byrne, of Capel Street in Dublin and Jacqueline Byrne of Kilnamanagh, Tallaght, Dublin, have both been accused of breaching medicinal products regulations.

The case was reportedly brought against them by the Irish Medicines Board (IMB) over products that were allegedly on sale at an adult shop called Shauna's located on Dublin's Capel Street, in 2010.

It is alleged that the proprietors kept and sold Kamagra tablets containing the prescription only medicine Sildenafil, a drug commonly used to treat erectile dysfunction.

They are also accused of stocking coconut, peach and passion fruit flavoured Kamagra oral jelly as well as a cream called Retardin, which reportedly helps prevent premature ejaculation.

A lawyer for the IMB told Judge John O'Neill this week that the trial was due to take place on May 14 but a different date was being sought to suit their witnesses.

Judge O'Neill heard that the trial is expected to last two days and there are to be two defense witnesses called.

O'Byrne and Byrne have both pleaded not guilty. Combined, they face twenty-five charges under the Medicinal Products regulations.
