This case report details a rare instance of pentazocine (Fortwin) abuse in a 32-year-old female. The abuse led to severe myogenic contractures of her knee joints, highlighting potential complications of opioid use.
Area of Science:
- Pharmacology
- Clinical Case Study
- Toxicology
Background:
- Pentazocine is a widely prescribed synthetic opioid analgesic for managing moderate to severe pain.
- Parenteral opioid abuse is associated with known complications such as skin ulcerations, abscesses, indurations, and sclerosis.
Observation:
- A rare case of pentazocine (Fortwin) abuse presented in a 32-year-old female patient.
- The patient exhibited severe myogenic contractures affecting her knee joints.
Findings:
- This case highlights an unusual presentation of pentazocine abuse.
- The drug abuse resulted in significant musculoskeletal complications, specifically knee joint contractures.
Implications:
- This case underscores the importance of monitoring for substance abuse in patients presenting with unusual or severe complications.
- Healthcare providers should be aware of the potential for rare, severe musculoskeletal complications arising from pentazocine abuse.
- Further research may be warranted to understand the specific mechanisms linking pentazocine abuse to myogenic contractures.

Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
