Because it Matters

Therapeutic Focus

Acute migraine headache attacks are moderate-to-severe headaches that can cause pulsing or intense throbbing sensations in the head. They are often accompanied by nausea, vomiting, and extreme sensitivity to light and sound.

CL-H1T

Sumatriptan & Promethazine

A novel combination of sumatriptan and rapid release promethazine, CL-H1T is currently being investigated for treatment of acute migraine attacks and the prevention or reduction of Migraine-Associated Nausea and Vomiting (MANV).

A clinically diagnosed migraine consists of at least 5 attacks lasting 4 to 72 hours when untreated.1

It is estimated that 35 million Americans suffer from migraines, but many of these people struggle to find relief because of their Migraine-Associated Nausea and Vomiting (MANV).1

Approximately 60%-90% of patients with migraines develop nausea during attacks.2

Approximately 50%-62% of patients with migraines experience vomiting during attacks.2

For these reasons, Charleston Laboratories is dedicated to developing novel combinations for the acute treatment of migraine attacks — without Migraine-Associated Nausea and Vomiting (MANV).

Nausea and vomiting significantly hinder migraine management by limiting oral absorption of treatments, in some cases causing more burden on the patient’s quality of life.2
