Sycrest – Asenapine uses, dose and side effects


5 mg and 10 mg resorbable tablets, sublingual

What Sycrest is and what it is used for

Sycrest contains the active substance asenapine. This medicine belongs to a group of medicines called antipsychotics. Sycrest is used to treat moderate to severe manic episodes in adults with bipolar I disorder. Antipsychotic drugs affect chemical signaling substances that enable contact between nerve cells ( neurotransmitters ). Illnesses that affect the brain, such as bipolar I disorder, can be caused by chemical neurotransmitters in the brain, such as dopamine and serotonin, being out of balance and this imbalance can cause some of the symptoms you may experience. It is not known exactly how this drug works, but it is believed to regulate the balance between these chemical neurotransmitters.

Manic episodes associated with bipolar I disorder are a condition with symptoms such as feeling “high”, having an excess of energy, needing much less sleep than usual, speaking very quickly with ramblings, and sometimes being very irritable.
