Major challenges hindering the growth of the global erectile dysfunction drugs market.

The global erectile dysfunction drugs market is expected to grow at a CAGR of -4.30% during the forecast period. Major challenges affecting the growth of the global erectile dysfunction drugs market include patent expiry of blockbuster drugs, side-effects of available drugs, and poor reimbursement scenario.

The drugs used for the treatment of erectile dysfunction increase the level of nitric oxide, which is a vasodilator. Vasodilators widen the blood vessels and increase the blood flow, which helps in maintaining penile erection. Thus, alterations in the blood flow, which are caused by these drugs, result in side-effects such as headache, body ache, dizziness, problems in digestion, vision changes, and congestion. In some cases, these drugs may also lead to harmful side-effects such as priapism and audio and visual impairments, including color blindness.

As a result of these side-effects, patients with erectile dysfunction often resort to alternative approaches such as natural supplements, acupuncture, and psychological treatments. These approaches are not as efficient as the drugs, but since they pose minimal side-effects, there is a high patient propensity toward them. Thus, the side effects of erectile dysfunction drugs available in the market are limiting the growth of the global erectile dysfunction drugs market during the forecast period.
