Dr. Suchdev, Dr. Mirazita and Dr. Yadati have once again been recognized by their peers as Top Doctors in New Hampshire Magazine’s annual Top Docs issue for 2025. This honor is recognition of their unwavering commitment to high-quality care, their expertise and skill in their respective fields, and the compassionate approach they offer patients at Oasis Therapeutics.
SPRAVATO® (esketamine) is a groundbreaking nasal spray approved by the FDA for adults struggling with two challenging types of depression:
Treatment-Resistant Depression (TRD): Designed for individuals who have not responded to at least two different antidepressants.
Major Depressive Disorder (MDD) with Acute Suicidal Ideation or Behavior: A rapid-acting option for individuals experiencing intense symptoms and an urgent need for stabilization.
Unlike traditional oral antidepressants that may take weeks to work, SPRAVATO® has been shown to deliver symptom relief in as little as 24 hours.
SPRAVATO® operates differently from standard treatments by acting on NMDA receptors in the brain. This novel approach helps reset neural pathways that contribute to depression. Administered in our certified treatment center at Oasis Therapeutics, patients self-administer the nasal spray under clinical supervision and remain on-site for observation for a minimum of two hours to ensure safety.
We work with many major insurance providers to help make SPRAVATO® accessible to our patients.

Response Rate:
Conventional antidepressant medications generally yield positive treatment responses in about 40% to 60% of patients. In contrast, clinical research on SPRAVATO® (esketamine) has reported response rates reaching up to 70% (Popova et al., 2019, American Journal of Psychiatry).
Onset of Therapeutic Effect:
Whereas standard antidepressants may require between four to six weeks before users begin to notice any significant improvement, esketamine (SPRAVATO®) has been associated with symptom relief in as little as 24 hours, according to clinical trial data (BMC Psychiatry, 2022).
Sustained Remission Rates:
In a clinical trial, 43.8% of individuals who continued treatment with Spravato alongside an oral antidepressant at the three-month mark had entered remission from major depressive episodes.
